Switch on the bulbs. If the bulbs light, then
switch off and proceed. If they do not light
isolate the electricity supply and perform
preliminary electrical system checks before
proceeding, ie earth continuity, polarity,
resistance to earth etc.
Release the pressure test point sealing screw from
the gas control tap and connect a pressure gauge in
position.
Push in the control knob, turn to the
Ignition/Pilot position ( ) and hold in.
Sparking will commence and the pilot
will light. The pilot is visible at the front
centre of the coalbed.
Continue to hold the control knob in for
a further 15 seconds, then release. The
sparking will stop and the pilot will remain
alight.
The pilot has two flames, one to ignite
the main burner and one to operate the
flame supervision device. Both flames
should be approximately 20mm long
with a clean and stable appearance.
If the pilot does not remain alight, wait
2 minutes and repeat the process. If the
pilot still fails to remain alight, refer to the
fault finding chart.
Turn the control knob to position 4
and check the setting pressure. If
this is not correct, check that all
gas cocks are fully open and that
the meter pressure is correct. No
adjustment to the setting pressure
is possible.
Turn the control knob to the OFF position ( ).
Disconnect the pressure gauge and replace the
pressure test point sealing screw, ensuring a gas tight
seal.
