13. CHECK APPLIANCE OPERATION
If closed, open the isolatng valve at the inlet elbow.
Turn on the gas supply and check all joints up to the appliance gas tap for gas
soundness using a soap solution or leak detection fluid.
Depress the control knob. While keeping it depressed, slowly turn to IGN position.
Turning the control should normally cause two consecutive sparks to occur between
the pilot hood and the electrode pin which should ignite the pilot gas.
The pilot flame can be seen by looking through the gap at the front of the right side
front coal.
If the pilot does not ignite, keep the knob depressed for a few seconds to purge air
from the supply pipes, then, turn back to OFF and repeat the ignition procedure.
When pilot ignition has been achieved, keep the control knob depressed for a few
seconds then release it. If the pilot does not remain alight ensure that the air has
been purged.
Partially depress the knob and turn to position 1. Both main and decorative flame
burners should light at the lowest setting. The decorative flames should just be
visible. If the decorative flames are visible, the main burner must be alight since it
lights the decorative burner.
Turn the control knob gradually to MAX position. Both burners should gradually
increase in output until at MAX position the main burner is at its greatest heat output
and the decorative flames are at their full magnitude.
Turn back to off after checking. Depress the control knob partially, turn clockwise
to OFF and release the knob. If any resistance is felt when turning, release the
downwards pressure on the knob before continuing to turn.
14. CHECK THE REFERENCE PRESSURE
The burner aeration is non-adjustable. The appliance is preset to give the correct heat
input on Natural Gas at 20 mbar (8in w.g) inlet pressure and no further adjustment is
necessary. The burner pressure should be checked at the pressure test point located
on the pipe connecting the gas tap to the main burner. The pressure check should be
carried out using a calibrated pressure gauge after removing the test point screw.
The fire should be alight and the control knob at MAX setting. The pressure setting
should be within the limits shown in the appliance specifications (see section 3).
After checking the pressure, turn off the fire, remove the pressure gauge and replace
the pressure test sealing screw. Relight the fire and test all gas joints for soundness
using a suitable leak detection fluid.
