La Nordica S.p.a. declines any responsibility for damage to things and/or persons caused by the
system. Besides, it is not responsible for the product that has been modified as well as for the use
of non-original spare parts.
Your usual chimney sweep must be informed about the installation of the thermo-fireplace in order to check
the regular connection to the chimney flue and the relevant efficiency.
Do not modify the appliance.
Before the installation, check if the floor can support the thermo-fireplace weight.
ATTENTION: make sure that the appliance is placed in a perfect plane position and that the
diameter of smokes pipe is the required one.
We suggest that your usual chimney sweep check both the connection to the chimney as well as the
sufficient air inflow for the combustion in the installation place.
The diameter of opening for the connection to the connection of chimney must correspond to the smoke
pipe diameter at least. The opening should have a connection to the wall to put inside the outlet pipe and a
rose window.
The thermo-fireplace 650 – 800 model MUST be installed in an OPEN EXPANSION TANK system.
The installation with open expansion tank must be provided with:
L’impianto con vaso di espansione aperto, deve essere obbligatoriamente provvisto di:
1. OPEN EXPANSION TANK which has a capacity of 10% of total water content of thermo-fireplace
and of the installation. This is installed at the highest point of the system, at least 2 m over the
radiator that is at the highest level.
2. SAFETY PIPE that connects through the shortest way, without descending or siphoning parts, the
delivery of thermo-fireplace to the upper side of small tank mentioned at point 1. The minimum
diameter of safety pipe is 1” gas.
3. LOADING PIPE which connects the bottom of small tank mentioned at point 1 with the return pipe
of installation. The minimum diameter must be ¾” gas. All those parts must no have for any reason
meditate intercept bodies that could accidentally exclude them and mut be placed in rooms which
are protected from frost. On the contrary, if they freeze, the boiler body could break or even
explode. In case of frost placing it will be right to add a proper percentage of antifreeze liquid to the
water of installation in order to delete the whole problem. In no way there must be water circulation
in the small tank between the safety and loading pipe. This would cause the water oxygenation and
the consequent corrosion of thermo-fireplace and installation in a very short time.
4. THERMAL DISCHARGE VALVE which is a further positive safety that prevents the boiling even
when electric energy is missing. It is made by a valve cover like a pressure safety valve which
differs from it as it opens by reaching a pre-calibrated temperature (normally at 94 – 95°C) and
unload hot water from the installation delivery. This will be replaced with as much cold water coming
from the small tank loading pipe of open tank by draining away the excessive heat.
5. 1,5 bar SAFETY VALVE. The exercise maximum pressure which is admitted for the installation is
1,5bar (it corresponds to 15m water column. Over pressures can cause deformations and breakings
of the boiler body.
6. SAFETY DEVICES according to the relevant rule in force.
7. CIRCULATION PUMP. It would be better to install it on the return in order to avoid that it could
disconnect itself at very high water temperatures but checking that it does not drive water in the
small tank of open tank otherwise it should cause a continuous water oxygenation with consequent,
fast corrosion of boiler body. It should mainly not exceed 3m of column water in order to avoid a
forced circulation in the small tank of open tank. Furthermore it must be electrically connected so
that it operates only when the water temperature is over 65-70°C. In order to obtain it is possible to
use the electronic control unit that can be purchased with the thermo-fireplace as OPTIONAL part
