7 Evacuation of combustion products
According to the type of building, to the insulation or to the air tightness of the building, there
are 3 possible solutions:
Type A - Throwing out of the combustion products into the atmosphere
Type B
- Individual fluting of each unit outside the building.
Type B - Appliances connected to a flue manifold system.
Type C - Balanced flue system, combustive air and combustion products taken/thrown from/to
the outside( by concentric air hole or separated pipes).
The following indications about the air renewal concern the good functioning of the
appliances. Do not forget also to take into account the rules concerning people leaving in the
heated premises
TYPE A
THROWING OUT OF THE COMBUSTION PRODUCTS INTO THE ATMOSPHERE
GAZ INDUSTRIE radiant tubes have a good combustion hygiene which has been controlled
for the
CE
mark. However, they can only be installed and used in
well ventilated premises
.
Radiant tubes can be installed without evacuation ducts for the combustion products within
the limits of the regulations in force. In that case, no modification has to be brought to the
units which are already equipped with a protection grille.
Attention : In public buildings, the evacuation of flue gases is obligatory.!!
* However we draw your attention to the fact that combustion products emitted into the
atmosphere can perceptibly modify the humidity level depending on the air change rate of the
building.
In case products of combustion are not evacuated outdoors, ensure that the location where
the unit is installed provides sufficient air to ensure a good functioning of the unit and the
dilution of the combustion products by
10 m
3
/h per kW installed
.
Do not allow combustion products to come into contact with combustible materials.
CAREFUL : refer to the rules in force.
