3.4.1.2 Ventilation by Mechanical Evacuation
Ventilation by mechanical 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 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 m
3
/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/m

4. ASSEMBLY
4.1.1 Assemble Burner Assembly to Basic Body Assembly
3.4.1.4 Air Supply
Air supply openings are required to admit air and shall be located below the radiant heaters.
The total area of the unobstructed cross-sections of all the air supply openings shall not be smaller
than the total area of the unobstructed cross-sections of all the exhaust openings.
Slits and gaps of fixed cross-section can also be used as air supply openings.
Where the air supply openings can be closed, it shall only be possible to operate the radiant heaters
when they are open.
Place the Orifice Plate (when supplied) into the venturi inlet of the Basic Body Assembly and press into position
against the shoulder. Insert the Burner Assembly spigot into the venturi inlet and align the Control Valve/Ignition
Control as shown in Fig 7: 4.1.
