SETTING THE STANDARDS FOR STOVES OPERATING
WITH INDEPENDENT EXTERNAL AIR
The German Institute for Buildings (DIBt) gives technical approval only to those stoves which, having undergone official laboratory
tests, conform to its strict criteria for safe burning without the use of the surrounding air, thus relying solely on an external independent
air source to provide all necessary combustion air. The tests check for CO concentration (ppm) in the flue gases and the leak rate
(m³/h) at 10 Pa after thermal and mechanical stress. For example, this includes testing the stove‘s door seal for air-tightness after
being opened and closed for a minimum of 6,000 times. All DAN SKAN Modern Line stoves conform to DIBt criteria.
APPLICATIONS
DIBt approved stoves need to be connected with a well sealed external air connection which has a valve mechanism to close the
external air off when the stove is not in use. Approved stoves can only be installed in rooms where it is proven that even with air
removed from the room by, for example, ventilation fans, extractor cooker hoods, hot-air heating systems and air dryers etc it is
guaranteed never to be less than 8 Pa negative pressure in the room or house.
The ideal pressure for the operation of a stove is 4 Pa and this is generally to be desired. It is also important that all flue pipe and
flue system connections are also well sealed. Important: Please check your local and national building regulations to ensure that
your proposed installation conforms.
AIRBOX: THE BENEFITS OF THE PATENTED AUTOMATIC AIR
REGULATION AND HEAT EXCHANGER
Cold air, drawn in from outside, should always be heated before arriving into the combustion chamber, in order to maintain the fire
chamber temperature which will ensure clean and efficient burning. External air can sometimes be extremely cold, often with
freezing temperatures, and would make the stove burn poorly, possibly even putting the stove out, and also making it burn dirty so
that it could fail today‘s environmental and emissions standards.
Our patented AIRBOX (which heats the air at the rear convection area of the stove) combinded with our intelligent automatic air
regulation system outlined earlier, enables you to get the very best out of your DAN SKAN stove and fuel every time by supplying
the fire chamber with the optimal quantity of air at a highly efficient pre-combustion temperature.
SITE REQUIREMENTS
The external air supply to the rear or base of the stove should be delivered through a 100 mm diameter duct provided that there is
only one bend and that the distance to the outside air is less than 5 m. All joints should be well sealed. Should the distance be greater
or the route require more than one bend then a 150 mm diameter duct must be used only reverting to 100 mm diameter when close to
the stove connection point.
Subject to local and national building regulations this duct should feature a shut off valve close to the outside air end to prevent cold
air entering the house when the stove is not in use.
The installation of a DAN SKAN stove incorporating the AIRBOX system within a house with a heat recovery system must comply with
local and national building regulations ventilation requirements. Please consult your installer or DAN SKAN partner who will be able to
advise.
BASE INLET LOCATION
It is recommended that the location of the base air inlet opening to take the 100 mm diameter external air duct should be positioned
at the centre rear of the stove beneath the stove base – see the diagram of a typical stove base floor plan.
