3.4 Ventilation
The installation room should have a volume of at least 10m ³ /kw of installed nominal heat input of the radiant
heater.
The ventilation requirements and calculation methods for unflued appliances are set out in the European
Standards
EN 13410:2001 and must be applied. The following is guidance to the standard:
Ventilation may be achieved by any of the three following different means:
a) thermal evacuation of the products of combustion/air mixture
b) mechanical evacuation of the products of combustion/air mixture
c) natural
air change
3.4.1.1 Ventilation by Thermal Evacuation
Ventilation by thermal evacuation is sufficient if 10m ³ /h of exhaust air per kW of operating heat input are
ventilated out of the installation room.
The air/products of combustion mixture must be evacuated above the radiant heaters, if possible near the ridge,
by means of exhaust mixture opening(s), (vents).
Where the exhaust mixture opening(s) can be closed, it shall only possible to operate the radiant heaters when
they are open.
The maximum horizontal distance between a radiant heater and a vent opening shall be:
6 (six) times the vent height in the case of wall openings
3 (three) times the vent height in the case of roof openings
