Check Control Settings
5.1.1
If closed
,
open the isolating valve at the inlet elbow.
5.1.2
To help in checking the control positions while the outer case is detached, place the
control bezel over the gas tap spindle and against the tap bracket. Temporarily secure to
the tap bracket with one of the screws.
5.1.3
Fit the control knob over the gas tap spindle.
5.1.4
Depress the control knob and turn anticlockwise partially towards the 1/IGN
position until some resistance is felt. Keep depressed at this position to purge air from the
system then, while keeping it depressed, turn fully to the 1/IGN position. A spark should
be generated at the pilot while turning. The spark should ignite the pilot.
5.1.5
When pilot ignition has been achieved, keep the control knob depressed for
approximately ten seconds to allow the thermocouple probe to warm up and then release
it. If the pilot does not remain alight, ensure that the air has been purged, that the pilot
orifice is clear and that the thermocouple connections are sound. Replace the pilot unit if
necessary (see servicing section of this manual).
5.1.6
Check all the control settings. These are:-
Knob Position
Burner appearance
1/IGN
Centre section on low. Outer sections off.
2
Centre section fully on. Outer sections off.
3
Centre section fully on. Outer sections on low.
4
Centre and outer sections fully on.
5.2
Check Burner Pressure
The appliance is pre-set to give the correct heat input at the inlet pressure shown in
section 1 of this manual. No adjustment is necessary. Check the burner pressure by fitting
a pressure gauge at the test point. The test point is on the pipe connecting the gas tap to
the lower injector. Check the pressure with the appliance alight and set at maximum
output (Control position 4).
