1. GENERAL NOTES

1.1 WARNING: For models which connect to mains electrical power, before exposing any of the internal

electrical wiring the appliance must be disconnected from electrical power by unplugging the service cord

from the electrical outlet. For models which connect to battery power, before exposing any of the internal

electrical wiring the appliance must be remove the battery also.

1.2 Any servicing carried out on gas containing components where seals are broken including manifold,

regulator, valves and burner supply pipes should be followed by a leak test. Gross leaks can be detected by

connecting a manometer to the regulator test point, pressurising the manifold and then shutting off the gas

with a ball valve. A falling manometer reading indicates a leak. Small leaks can be located with soap and

water applied at the connection.

1.3 Burner supply pipes leading from the burner control to the burner should have their compression fittings

tightened firmly but not over tightened (If a torque spanner is used set this to 10  12Nm). If the tubes are

damaged they should be replaced. The soundness of the connections on the burner supply tubes can be tested

by blocking the injector orifice temporarily, eg. by fitting an injector that has been blocked and leak testing

the fittings.

1.4 When reassembling the appliance any earth leads which have been disconnected must be re-connected.

1.5 Reassembly procedures are a reversal of removal procedures.

1.6 Replace the spare part with original spare parts. The modify part must not be used.

1.7 All the screws in this appliance have been designed for difference purpose. They must be use in the right

position and must be the right dimension. If there are any differences from the original design they may have

the serious accident.

Gas from the tank (1) is released from the low pressure regulator (2) into the hose or tube (3), travelling pass

the elbow coupling to the valve (4). To ignite the burner, press down and turn the safety valve (5) counter-

clockwise simultaneously. This opens up the valve, letting the gas to the nozzle of the burner (6), and turns the

ignition switch to on (7) at the same time. The electrical current is automatically supplied from the battery to

spark plug generator (8), and then to the pin heads (9), causing the ignition (10). The burner is ignited and bursts

into flame (11).
