Section 10. Conversion Between Gasses
(On/off Burner)
10.1
General
All versions of the heaters use the same main burner bars and pilot burners.
Natural Gas
All natural gas versions use the same main burner injectors marked 840, and pilot injectors marked
34.
The gas valves vary according to the models size but in all cases the valve contains a gas pressure
regulator to allow for setting of the burner pressure.
L.P.G.
All L.P.G. versions use the same main burner injector marked 250, and pilot injectors marked 19.
The gas valves vary according to the models size and method of control i.e. manual or automatic
ignition but in all cases the valve DOES NOT contain a gas pressure regulator.
The correct operation of the heater depends on the close control of the gas inlet pressure to the
appliance.
10.2
