3.4 Ventilation
The installation room should have a volume of at least 10m3/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 Standard 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 10m3/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 be 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
3.4.1.2 Ventilation by Mechanical Evacuation
Ventilation by mechanical evacuation is sufficient if 10m3/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 using fan(s).
It shall only be possible to operate the radiant heaters whilst the exhaust airflow is proven.
The maximum horizontal distance between a radiant heater and a fan shall be:
6 (six) times the fan mounting height in the case of wall openings
3 (three) times the fan mounting height in the case of roof openings
Total minimum proven ventilation airflow in m3/h will be:
Total installed kW input X 10
Note: Mechanical exhaust air openings must be positioned such that the burner stability of the
nearest appliance is unaffected.
3.4.1.3 Ventilation by Natural Air Change
Gas-fired radiant heaters may be operated without any special exhaust system if the exhaust gases
are discharged to the outside atmosphere by a sufficient natural air change in the installation room.
Furthermore, no provision for thermal or mechanical ventilation is required in the following particular
cases:
buildings with natural air change greater than 1.5 volumes per hour
buildings with a density of operating heat input not greater than 5W/m3
