11.2.2
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 / IGN’ 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 /
IGN’ 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 as described in the servicing section of
this guide.
11.3 Inlet pressure check.
The appliance is pre-set to give the correct heat input at the inlet pressure shown in
section 3 of this guide. 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
elbow (See figure 22). 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.
When the above checks from section 11.2 and 11.3 have been completed close
the isolating valve on the inlet elbow
