10.2.2 Operating the burner.
1.
When the pilot burner is operating properly, gradually turn the control knob anti-
clockwise to 'HIGH' (Depress the knob slightly to get past the pilot ignition position).
The main burner should now light. Depress the control knob slightly to release from the
'HIGH' position and turn back (clockwise) to 'LOW'. While turning, the burner flames
should gradually become lower but remain alight. Depress the control knob slightly to
release from the 'LOW' position and turn back (clockwise) to the ‘Pilot / ignition’
position. The main burner should extinguish but the pilot should remain alight. Depress
the control knob slightly and turn back (clockwise) to turn OFF.
This will extinguish the pilot.
If the above checks are satisfactory, continue with the installation. If not, check the
control and ignition circuitry and components.
10.3 Inlet pressure check.
The appliance is pre-set to give the correct
heat input at the inlet pressure shown in
section 2 of this manual. No adjustment is
necessary.
1.
Check the inlet pressure by fitting a
pressure gauge at the test point. The test
point is on the inlet ‘T’ connector (See
figure 17). Check the pressure with the
appliance alight and set at maximum
output.
2.
After checking, turn off the appliance.
Remove the pressure gauge and replace
the test point sealing screw.
3.
Relight the appliance. Turn to the
maximum output position and test around the
sealing screw for gas soundness with a suitable
leak detection fluid.
10.4 Fitting the burner tray trim on Avignon
and Avignon Aspire models.
1.
Fit the burner tray trim over the front rim of
the burner tray. Push the trim fully down (See
figure 18).
