INSTALL ATION<br />

Taking delivery of the stove<br />

Please check carefully that the stove is in perfect condition. Make sure that it has not been<br />

damaged in transit. Pay particular attention to the glass door and the fireclay bricks inside.<br />

Should you discover any damage, please inform your supplier at once. Do not light a fire<br />

in the stove.<br />

Damage sustained by the glass door and the fireclay bricks after the stove has been<br />

used is almost always caused by overheating or incorrect operation. In such cases, the<br />

manufacturer‘s guarantee will not apply and we will not be liable for any damage.<br />

CORRECT LOCATION<br />

n When choosing the location for your stove, make sure that it can be connected easily to<br />

the chimney in your house. Before installing the stove make sure you are aware of all the<br />

applicable national and local building regulations.<br />

n DROOFF stoves are normally delivered with an interchangeable connecting sleeve which<br />

makes it possible to fit the stovepipe both from the rear and from above (see data sheet<br />

"Technical Information"). As a rule, your stove will be prepared for connection from the<br />

top. However, if you prefer a different connection, replace the connecting sleeve with the<br />

sealing lid. It is extremely important that the opening which is not in use is firmly sealed<br />

with the lid.<br />

n The floor under the stove must be flat and level. Before installing the stove, make sure that<br />

the floor is able to bear the weight.<br />

n The floor under the stove must be resistant to heat and non-combustible (e.g. tiles or<br />

special floor plate). This non-combustible area must extend at least 50 cm in front of the<br />

stove and at least 30 cm to the side, measured from the front of the door.<br />

n The stove and the connecting pipe must be at a certain distance from combustible<br />

materials at the back and at the sides. They must also have a certain clearance from steelreinforced<br />

concrete walls. For the necessary safety clearances for your stove, please refer<br />

to the data sheet "Technical Information" or the plate attached to the back of the stove. For<br />

the necessary safety clearances for the connecting pipe, please refer to the data supplied<br />

by the pipe manufacturer.<br />

n Always ensure that no combustible objects or objects sensitive to heat are placed close<br />

to the glass door. See data sheet "Technical Information" for adequate clearances.<br />

CHIMNEY<br />

The stove functions by a simple principle of physics i.e. that hot gas rises. This means that the<br />

smoke and hot gas produced by the fire rise up through the chimney while fresh air for combustion<br />

is sucked into the fire chamber from the room or from outside (with stoves fitted with<br />

an outside air inlet). The upward draught from the chimney is therefore the "motor" of the stove.<br />

This draught is affected by a number of factors such as the cross section (wideness) of the<br />

chimney, its height and its insulation as well as the temperature outside the house.<br />

Every stove has its own characteristics. Deflection (i.e. changes in direction) of the smoke gas<br />

improve the efficiency of the stove but also creates resistance. The temperature and quantity of<br />

smoke gas produced differs from one stove type to another. Every stove therefore makes its own<br />

demands on the chimney. It may well happen that a good stove and a functioning chimney are<br />

incompatible and have to be adapted to one another. Always ask your stove dealer or a heating<br />

engineer if your chimney is suitable for your stove.<br />

n Connection to chimney<br />

The planned connection of a stove to a chimney must be approved according to national and<br />

local building regulations and carried out by a qualified engineer. The connection must also be<br />

officially tested before the stove is put into operation.<br />

DROOFF stoves are all designed according to type 1 with a self closing door to the fire chamber.<br />

They can be connected without difficulty to a suitable chimney which is already in use.<br />

The components required for connecting the stove to the chimney are not supplied with the<br />

stove. These components can be obtained from your dealer. For the correct diameter for the<br />

connecting sleeve of a DROOFF stove please refer to the attached data sheet "Technical<br />

Information". Smoke pipes complying with the standard EN 1856-2 are suitable for use with<br />

the stove. Always ensure that the smoke pipe is installed at the correct safe distance from<br />

combustible substances and materials.<br />

Wood burning stoves are technically complex devices. They function efficiently and safely only<br />

when installed and connected to a suitable chimney in accordance with all technical rules and<br />

regulations.<br />

You are therefore advised to have your stove installed and connected to the chimney<br />

by a qualified engineer.<br />

n Important notes for connecting the stove:<br />

n The measurement of the chimney must comply with EN 13384, parts 1 and 2.<br />

n Comply with the standard DIN 18160.<br />

n For the minimum suction pressure, see data sheet "Technical Information". The maximum<br />

suction pressure is 20 Pa. For pressures higher than 20 Pa, pressure restriction is required.<br />

n All smoke pipe connections must be absolutely free of leaks.<br />

n The smoke pipe must not project into the chimney.<br />

n Connections for other smoke outlets (fireplaces etc.) must not be at the same level or lie<br />

opposite one another in the chimney. The minimum distance is 40 cm.<br />

n When the smoke pipe is connected to the top of the stove its height must not exceed<br />

150 cm. Always observe the correct safe distance from ceilings, ceiling panelling etc.<br />

For the correct dimensions and data for connecting the stove to the chimney, refer to the<br />

data sheet "Technical Information".<br />

Please read the following before lighting the fire!<br />

SAFETY<br />

n Read these instructions through carefully to find out how to operate the stove safely.<br />

n For the set up, connection and operation of the stove, always observe all applicable national<br />

and European standards as well as all applicable local regulations. If in doubt, consult<br />

your dealer or a qualified heating engineer.<br />

n Check again to ensure that the stove has been correctly connected to the chimney.<br />

n When the fire is burning, the outer surface of the stove becomes very hot. Keep children<br />

and animals under supervision.<br />

n When the fire is burning, make sure that there are no combustible materials or substances<br />

near the stove or on the stove.<br />

n Keep the door to the fire chamber closed at all times, even when the fire is not burning.<br />

(Exception: when heating the stove for the first time).<br />

n Do not overheat the stove by using too much fuel as this may damage the stove or the<br />

chimney and entail loss of guarantee rights.<br />

n Never use petrol, paraffin, methylated spirit or other dangerous substances to light the fire.<br />

n Do not place objects made of combustible material in area affected by radiant heat from<br />

the stove, i.e. within a radius of about 85 cm of the glass door.<br />

n Make sure that the ash box is never completely full as this prevents sufficient air from<br />

reaching the fire and may cause the bottom grate to overheat and warp.<br />

(continued on page 7)<br />

n Make sure that enough fresh air can flow into the stove. Remember that your stove<br />

needs about 4 m 3 of air to burn 1 kg. of wood!<br />

n If a kitchen fume extractor is being used in the same or in a neighbouring room, this may<br />

reduce the air pressure around the stove and cause smoke gases to leak out into the room.<br />

It is recommended to install a window contact switch for the fume extractor. Consult your<br />

heating engineer on this subject.<br />

n Do not remove the ash when it is hot. Store the ash in non-combustible containers only.<br />

Do not place such containers on combustible or heat sensitive surfaces.<br />

n For the correct distances between the stove and combustible or valuable objects, refer to<br />

the data sheet "Technical Information" or the plate mounted on the stove.<br />

OPERATING <strong>INSTRUCTIONS</strong><br />

SUITABLE FUELS<br />

For information on the fuels approved for use in your DROOFF stove, refer to the data sheet<br />

"Technical Information" or the plate mounted on the stove.<br />

Wood — our fuel<br />

There are many reasons why wood is an important raw material and source of energy. It is a<br />

renewable material which grows "at our own front door". Our forests are cultivated sustainably,<br />

i.e. the same amount of wood matures at any given time as is harvested or burned. Whether<br />

the wood is burned or lies on the ground and rots, it emits only the same amount of CO 2 as<br />

the tree has absorbed during its life. Wood is also cheaper than oil or natural gas. A woodfired<br />

stove is therefore the most effective way of keeping heating costs down.<br />

n Logs<br />

Use only dry wood! Logs have to be stored in the open air for a period of 1.5-2.5 years to<br />

achieve a residual moisture content of between 15% and 20% which is most suitable for burning.<br />

To measure the residual moisture content of wood, use a standard moisture measuring instrument<br />

which you can purchase from your dealer. The calorific value of wood depends to a great<br />

extent on its quality and moisture content. The more water it contains, the more heat is<br />

required for its evaporation during combustion. That means that the damper the wood is, the<br />

lower its calorific value.<br />

Freshly cut wood contains a lot of moisture and therefore burns badly. The heat it gives off<br />

(i.e. its calorific value) is low and it pollutes the atmosphere. In addition, the high amounts of<br />

conden sation and tar in the smoke gas lead to undesirable deposits in the stove and the<br />

chimney and obscure the glass window more quickly.<br />

The calorific value of wood differs from one type of wood to another. In relation to their weight,<br />

the calorific value of soft woods such as spruce, pine or fir is considerably higher than that of<br />

harder woods such as birch, oak or beech. However, in relation to their volume, it is the harder<br />

woods which have a higher calorific value.<br />

DROOFF Kaminöfen — Feuer aus dem Sauerland


OPERATING <strong>INSTRUCTIONS</strong> Page 9<br />

w w w. d r o o f f - k a m i n o f e n . d e<br />

The calorific values of different wood types is shown in the following table:<br />

Hard wood kWh per kg Soft wood kWh per kg<br />

Birch 4.30 Spruce 4.50<br />

Beech 4.00 Pine 4.40<br />

Oak 4.20 Fir 4.50<br />

Soft wood burns faster than hard wood and achieves higher temperatures. This is due mainly<br />

to the high resin content. However, for heating purposes, the slower and more lasting development<br />

of heat is generally desired. The suitability of a certain type of wood therefore depends on<br />

the user‘s purpose. Harder woods burn more slowly and supply energy over longer periods of<br />

time. This may be useful for overnight heating. On the other hand, the more rapid combustion<br />

and faster energy emission of soft wood may be more suitable for heating cold rooms more<br />

quickly.<br />

n Preparation and storage<br />

Wood needs time to dry. When stored correctly, wood has a residual moisture content of 19%<br />

after between 1.5 and 2.5 years. It is then "air dry" or seasoned.<br />

Useful tips:<br />

n Saw and split the wood before stacking it. This helps it to dry more quickly.<br />

n Stack your firewood in a sunny well ventilated place where it is sheltered from rain.<br />

n Leave a gap between the stacks to allow the air to circulate and remove moisture.<br />

n Do not cover the wood with plastic sheeting. This prevents moisture evaporating.<br />

n Do not stack fresh wood in basement rooms. The low air circulation will cause it to rot<br />

rather than dry.<br />

n Keep some wood close to the stove to warm it up to room temperature.<br />

OPERATING <strong>INSTRUCTIONS</strong><br />

n Lignite briquettes<br />

Standard shaped lignite or brown coal briquettes may also be used if this is stated in the<br />

list of approved and tested fuels for your particular stove or are listed on the metal plate<br />

mounted on the stove. You will heat your house without unnecessary air pollution only if you<br />

use the approved fuels mentioned in this booklet. You can also further reduce emissions by<br />

stoking your stove with the quantities stated in the data sheet "Technical Information".<br />

Burning the following types of fuel in your stove is prohibited by law:<br />

n Damp wood and wood treated with preservatives<br />

n Painted wood and wood coated with synthetic material<br />

n Wood chippings<br />

n Bark and chipboard waste<br />

n Coal dross<br />

n Waste<br />

n Paper and cardboard (except for lighting)<br />

Remember: a wood burning stove is not a rubbish incinerator! The burning of rubbish<br />

and waste is prohibited. This pollutes the environment and damages your stove. Use<br />

only well seasoned suitable types of wood and (if stated explicitly) lignite briquettes.<br />

FUEL QUANTITIES<br />

To avoid unnecessary air pollution, stoke your stove only with the quantity of fuel you actually<br />

need for your heating requirements.<br />

To achieve the rated heating capacity of your stove you need only 2-3 logs or 3-4 lignite<br />

briquettes. For more detailed information refer to the data sheet "Technical Information".<br />

Depending on the weather, chimney draught, wood quality and the position of the adjusting<br />

slide on the stove, one stoking of wood will burn down to a red glow in about 30-45 minutes.<br />

OPERATING <strong>INSTRUCTIONS</strong> Page 11<br />

FUNCTION OF STOVE<br />

n Primary air is required for heating up the stove and for burning mineral fuels e.g. lignite<br />

briquettes. The primary air is sucked into the fire chamber from below, in most cases<br />

through the grate.<br />

n Secondary or "glass cleaning" air is required for burning long-lasting materials such as<br />

logs, wood briquettes and lignite briquettes. Secondary air enters the fire chamber from<br />

above. It also serves to keep the glass window clean for as long as possible (see notes on<br />

page 14).<br />

n Tertiary air is additional secondary air. With most stoves, the tertiary air is set by the<br />

manufacturer and cannot be changed. However, this varies from one stove to another.<br />

n Depending on type, DROOFF stoves are fitted either with a shaker grate or a fixed grate.<br />

The primary air flowing through the grate to the fire helps to cool the grate. For this reason<br />

it should be kept free at all times.<br />

n All DROOFF stoves are fitted with an ash box. The ash falls through the grate into the box.<br />

The amount of ash created depends on the type and amount of fuel burned and should<br />

be emptied every few days.<br />

n DROOFF stoves are designed according to type 1. This indicates a simple but effective<br />

safety system. Should you forget to close the stove door after stoking it, it will close automatically<br />

thereby preventing burning wood from falling out. However, always make sure that<br />

the door to the fire chamber is properly closed at all times.<br />

n Most DROOFF stoves can be connected to an external source of fresh air. An external air<br />

supply is generally required when the space where the stove is standing is very confined. In<br />

this case, most of the air is supplied to the fire chamber from outside. A qualified heating<br />

engineer will tell you whether an outside connection is necessary in your case.<br />

Important note: if your stove does not receive air from outside, make sure that the room<br />

has a sufficient supply of fresh air. The stove requires approximately 4 cubic metres of<br />

air to burn 1 kg of wood!<br />

DROOFF Kaminöfen — Feuer aus dem Sauerland

w w w. d r o o f f - k a m i n o f e n . d e<br />

OPERATING <strong>INSTRUCTIONS</strong><br />

FIRST HEATING UP<br />

Always keep the stove under supervision when the door of the fire chamber or the ash<br />

box are not firmly closed!<br />

Before lighting the fire for the first time make sure you have removed all the accessories from<br />

inside the stove or the ash box. Make sure that there is nothing on top of the stove and that<br />

the convection openings are not obstructed. Open the doors and windows to ensure sufficient<br />

ventilation. The reason for this is that the stove is coated with a heat resistant lacquer which<br />

only achieves its final hardness after about one day‘s burning at the rated heating capacity<br />

of the stove. This may produce an unpleasant smell which disappears when the lacquer has<br />

hardened. When the fire is lit for the first time, allow the door to fall back into position but do<br />

not lock it. This prevents the sealing cord from adhering to the lacquer. This also applies for<br />

the ash box. Remember! Keep a watchful eye on the on the stove for as long as the door to<br />

the fire chamber or the ash box are not firmly locked into position!<br />

n Open the primary and secondary air slides completely. Leave them open during the whole<br />

of the first warm up.<br />

n Take the kindling material (not petrol, paraffin etc.) such as standard fire lighters and lay<br />

small pieces of wood on the grate. Light the fire lighters.<br />

n As already mentioned, close the door but do not lock it into position.<br />

n At this point the stove system is still cold, i.e. the stove, stovepipe and chimney have not<br />

yet reached the desired operating temperature. By leaving the door slightly open during<br />

the kindling phase you assist this whole process. When you add more material to the<br />

flames some smoke may escape into the room.<br />

n Allow the first pieces of wood to burn down until there is only a red glow. Open the door<br />

slowly to allow the pressure on both sides to equalise and prevent smoke from escaping.<br />

n Do not re-stoke with fresh fuel too soon. Avoid a pile up of hot glowing embers on the<br />

grate through stoking too soon. This may cause damage by overheating.<br />

n If necessary remove ash by shaking the grate or raking it through.<br />

The stove must remain in operation for a number of hours until the lacquer has<br />

hardened completely.<br />

DROOFF Kaminöfen — Feuer aus dem Sauerland


OPERATING <strong>INSTRUCTIONS</strong> Page 13<br />

w w w. d r o o f f - k a m i n o f e n . d e<br />

CORRECT <strong>OPERATION</strong><br />

n If necessary remove the ash from the fire chamber and empty the ash box if it is full.<br />

n Close the door of the ash box or push the box firmly into position.<br />

n For routine use of the stove (i.e. the stove lacquer has fully hardened), light the fire as<br />

described above. Leave the door open slightly until the fire is burning briskly. Then close<br />

it firmly.<br />

n Do not re-stoke with fresh fuel until the fire has burned down to the glowing embers.<br />

Open the door slowly to allow the pressure to equalise and prevent smoke from escaping.<br />

n Depending on the draught of your chimney and the type of fuel used, the flow of primary<br />

and secondary air must be adjusted during the burning process. For information on the<br />

correct adjustment, refer to the data sheet "Technical Information". As a rule, the primary<br />

air slide is kept completely closed so that no air reaches the flames from below. The<br />

secondary air slide on the other hand remains open. Depending on the weather, chimney<br />

draught, wood quality and the position of the adjusting slide on the stove, one stoking of<br />

wood will burn down to a red glow in about 30-45 minutes.<br />

n Then re-stoke again and proceed as described above.<br />

Important note: do not control the heat emitted by your stove by the position of the<br />

air slides only, but also by varying the amount of fuel as required.<br />

<strong>OPERATION</strong> BETWEEN THE SEASONS<br />

At an outside temperature of approx. 15° C or higher, it may become more difficult for your<br />

stove to function properly. The small difference in temperature tends to reduce the upward<br />

draught in the chimney, making it difficult to light the fire and to "get it going". In addition,<br />

greater quantities of smoke is produced which cloud the window with soot and billow into the<br />

room if the stove door is opened.<br />

If it is difficult to light the fire, try burning a crushed up sheet of newspaper. This produces<br />

a short lived upward draught of hot air which may help to dissipate the smoke in the fire<br />

chamber.<br />

When outside temperatures are still relatively high, make sure that enough air is available<br />

for combustion. Open the primary and secondary air slides more than usual and ensure that<br />

there is not too much ash on the grate. Avoid slow burning of the fire and empty the ash box<br />

more often.<br />

OPERATING <strong>INSTRUCTIONS</strong><br />

ENVIRONMENT<br />

Heating with wood reduces air pollution because wood is simply stored up solar energy.<br />

If it is properly operated, your stove will always comply easily with even the strictest European<br />

regulations. However, this is largely dependent on the way you use it and on the<br />

type of fuel you burn. Always adhere to this instruction booklet. Burn only well seasoned<br />

wood or (if approved) lignite briquettes.<br />

Do not just use the air slides to control the heat emitted by the stove, but vary the<br />

amount of fuel you burn according to your needs.<br />

MAINTENANCE<br />

Good care and maintenance are essential to ensure the long life span and efficient function<br />

of your stove. We recommend that you have your stove checked once a year by a qualified<br />

heating engineer. Your dealer will also be pleased to do this on request.<br />

CARE <strong>AND</strong> CLEANING<br />

Clean your stove only after it has cooled down completely and contains no hot embers<br />

or ash.<br />

n Cleaning the glass surfaces<br />

DROOFF stoves are designed in such a way that the secondary air blows the smoke away from<br />

the inside of the glass. If the stove has been correctly installed, the chimney conditions<br />

are suitable and the correct type of fuel is used, the inside of the glass will require very little<br />

cleaning. However, slight clouding cannot always be avoided. On the other hand, if the wood is<br />

not dry enough or the chimney draught not strong enough the glass will soon be coated with<br />

soot. The glass surfaces are easiest to clean with a dry soft cloth or if necessary, mild glass<br />

cleaning fluid.<br />

Do not clean the glass window with abrasive materials or scraping tools. This may cause hair<br />

line cracks to develop in which soot will accumulate which is difficult to remove.<br />

Very stubborn dirt can be removed with special stove glass cleaners which are available from<br />

your dealer.<br />

DROOFF Kaminöfen — Feuer aus dem Sauerland


OPERATING <strong>INSTRUCTIONS</strong> Page 15<br />

w w w. d r o o f f - k a m i n o f e n . d e<br />

n Cleaning lacquered surfaces<br />

To remove soot from lacquered surfaces, use only a soft dry cloth. Do not use abrasives,<br />

solvents or similar substances. Remember that your stove may be lacquered, but it is not<br />

entirely rustproof.<br />

If the stove is overheated, a slight grey discolouration may appear on the outer surface.<br />

Discoloured areas can be retouched using a standard heat resistant stove lacquer. This may<br />

produce an unpleasant odour until it has hardened fully. Make sure that the room is well<br />

ventilated.<br />

n Cleaning the fire chamber<br />

Clean the fire chamber regularly (or whenever required) and empty the ash box. The amount<br />

of cleaning will depend on the type of wood burned and on how frequently the stove is used.<br />

n Disposing of ash<br />

To remove ash from the fire chamber, use a small shovel or similar tool. Metal ash containers<br />

which can be attached to a vacuum cleaner are excellent for this purpose. Make sure that<br />

the ash has cooled down and contains no hot embers. Use only fireproof non-combustible<br />

containers to store the ash. Do not place these containers on combustible or heat sensitive<br />

surfaces. If in doubt, consult your dealer.<br />

CAUTION! Do not put the ash in a rubbish bag or use a vacuum cleaner without an<br />

intervening ash container made of metal.<br />

n Maintenance of seals<br />

The seals on doors and glass windows are subject to wear and tear due to continuous exposure<br />

to heat. Check them regularly and replace them at least once a year, or ask your dealer<br />

to do this.<br />

n Cleaning the fire chamber and connection piece<br />

Using a vacuum cleaner or small brush, clean the interior of the fire chamber and the<br />

connection area to the stove pipe at least once per year.<br />

resistant grease (heat resistance up to 1100°C, e.g. copper paste). (fig. 2).<br />

(fig. 2)<br />

n Cracks in the fireclay brick are unavoidable due to continuous exposure to heat.<br />

Under normal conditions these do not adversely affect the function or durability of<br />

the stove.<br />

Your stove is tested by the manufacturer to the standard EN 13240. It must not be<br />

modified in any way as this may lead to loss of approval for use and render the guarantee<br />

invalid.<br />

TECHNICAL IN<strong>FOR</strong>MATION<br />

RATED THERMAL OUTPUT<br />

The actual thermal output of a stove depends on the amount of fuel with which it is actually<br />

stoked.<br />

The "rule of thumb" is: 1 kg wood = 3 kW heat output.<br />

The rated thermal output is stated on the plate attached to the stove. The rated thermal<br />

output is the thermal output which is determined by testing a stove to EN standard and then<br />

stated by the manufacturer. To achieve this rated output, a certain defined amount of fuel has<br />

to be burned. This amount is stated in the data sheet "Technical Information".<br />

THERMAL OUTPUT RANGE<br />

Every wood burning stove has a range of thermal outputs. Your stove will also function<br />

perfectly at ouputs which are less than the rated output. The high quality of DROOFF stoves<br />

even permits outputs which are slightly higher than that rated. Less fuel means a lower<br />

output, more fuel, a higher. This flexibility makes our stoves more economical. The thermal<br />

output range is stated in the current instruction booklet.<br />

Ensure that your stove is not overheated either for shorter or longer periods of time. Damage<br />

caused by overheating is not covered by the guarantee. Please refer to the section entitled<br />

"Guarantee". Always operate your stove according to the instructions and stoke it only with<br />

the correct amounts of fuel i.e. no more than you need for your actual requirements. Do not<br />

use only the air slides to control the heat emitted by the stove, but also vary the amount of<br />

fuel you burn.<br />

The stove is designed for intermittent use. Do not overheat it, even for short periods of time.<br />

Depending on the quality of the fuel, the chimney and the weather conditions, it will take<br />

approx. 30-45 minutes for one stoking of fuel to burn down. When it has burned down to the<br />

red embers, the stove can be re-stoked.<br />

After firing up, we recommend selecting the setting "maximum thermal output". This is the best<br />

way to avoid unnecessary pollution. Do not use only the air slides to control the heat emitted by<br />

the stove, but also vary the amount of fuel you burn. Use only as much fuel as you need<br />

for your actual requirements. This improves the efficiency of the stove and helps protect he<br />

environment. The position of the slides can be varied according to the chimney draught and<br />

the weather conditions. Always ensure that the fire has enough air to burn down completely.<br />

Ventilation<br />

At the lower rear side of the stove is a 100mm diameter hole that facilitates the entry of air<br />

into the combustion chamber. If required, the combustion air requirements can be piped<br />

to outside. Consideration should be given to wind affecting the outside terminal and the<br />

possibility of condensation forming within the piping. Installation work for the ventilation<br />

should always be carried out by a qualified engineer.<br />

Attention! Danger by insufficient ventilation!<br />

n Your dealer or qualified engineer will calculate and advise you on ventilation requirements.<br />

n Do not obstruct ventilation openings or grilles.<br />

n Specialist advice should be sought if you have any mechanical extraction either within the<br />

heated room or adjacent rooms.<br />

n Beware of aggressive chemicals being stored near ventilation openings or terminals.<br />

Fluorine and chlorine solutions can and will cause corrosion.<br />

n A lack of ventilation will seriously affect performance and combustion and is a serious<br />

threat to life and health.<br />

n A carbon monoxide alarm must be fitted on all installations and regularly checked.<br />

n Ventilation openings should be checked and cleared of debris regularly.<br />

AVOIDING MISTAKES<br />

The stove does not draw in enough air or smokes when being re-stoked<br />

Is the draught in the chimney too low?<br />

Is there a leak in the stove pipe or the chimney? Are any connections leaking?<br />

Does the stove pipe project into the chimney?<br />

Is the door of another stove open which is connected to the same chimney?<br />

Is the wood dry? Is it cut to the right size?<br />

Is the deflection plate in the right position?<br />

IMPORTANT NOTE<br />

Damage to the stove caused by<br />

non-compliance with these<br />

instructions is not covered by<br />

the guarantee.<br />

The stove does not give off enough heat<br />

Is the room too big for the stove?<br />

Is there too much ash on the grate?<br />

Is the ash box full?<br />

Is the stove pipe blocked?<br />

Are primary or secondary air slides closed?<br />

Is the connection between stove and chimney leaking?<br />

Is the wood dry? Is it cut to the right size?<br />

The stove gives off too much heat<br />

Are primary or secondary air slides open too far?<br />

Is the door of the fire chamber closed properly?<br />

Is the ash box closed properly?<br />

Is the draught in the chimney too high?<br />

Is there too much fuel on the fire?<br />

The window becomes too sooty<br />

Is the chimney draught ok? Soot deposits on the glass may be caused by chimney draught<br />

which is too high or too low.<br />

Are you using the right amount of fuel?<br />

Is the wood dry? Is it cut to the right size?<br />

Is the fire receiving enough air to burn with a bright flame?<br />

Chimney on fire<br />

The use of damp fuel or fuel of the wrong type may cause soot deposits in the chimney which<br />

can ignite. In case of a chimney fire, close the primary and secondary air slides and the door<br />

to the fire chamber. Call the fire service, heating engineer, chimney sweep. Before re-lighting<br />

the fire, have the chimney inspected by a qualified engineer. Do not attempt to extinguish<br />

the fire with water. This may cause an explosion of steam in the chimney, causing serious<br />

damage to the building.<br />
