system

9.3 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.

9.4 Lighting the fire

If closed, open the isolating elbow valve. 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 thermocouple 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.

If there are no sparks or the sparks appear weak check

the spark gap between electrode wire and thermocouple

tip. See figure 23.

9.5 Operating the burner.

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.
