7.1 Preliminary burner checks.
Some burner operations can be checked at this stage. Checking now will mean that less disassembly will be
required if any problems are found.
A full check should still be made, however, after final installation.

7.1.1
Lighting the fire
If closed, open the isolating inlet 'T' connector. Depress the control knob and rotate it anticlockwise to the pilot
ignition position. A 'click' will be heard as the integral piezo operates. A spark should be seen between the
electrode and pilot tip. Turn the control knob clockwise to the 'Off' position. Repeat this operation until a flame
appears at the pilot. There may be a delay before the pilot lights due to air being purged from the system.
When a flame appears at the pilot keep the control knob depressed and hold the pilot ignition position for five
seconds. When the control knob is released the pilot flame should remain lit.
7.1.2
Operating the burner.
When the pilot burner is operating properly, gradually turn the control knob anticlockwise 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.
7.1.3
Checking the inlet pressure.
The appliance is pre-set to give the correct heat input at the inlet pressure shown in
section 3
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 7
). Check the pressure with the appliance alight and set at maximum output.
