11. BURNER & SUPPLY PIPE INSTALLATION
11.1 Fitting the burner.
1.
Place the burner module into the hotbox. Secure using the two screws removed
previously.
11.2 Supply pipe installation.
A nut and olive is provided for an 8mm-pipe inlet connection directly to the gas control.
The isolating ‘T’ connector can be rotated to allow a connection from any direction. The
‘T’ connector includes a valve for isolating the gas supply.
The supply pipe must be rigid material. Flexible pipe must not be used. Connect the
supply line to the appliance.
Turn on the gas supply and pressure check the installation pipework for gas soundness.
In the United Kingdom (GB) check in accordance with the current edition of BS 6891.
In the Republic of Ireland check in accordance with the current edition of IS 813

11.3 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.
11.3.1
Lighting the fire.
If closed
,
open the isolating ‘T’ connector 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 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.
If there are no sparks check that the electrode lead is connected to the electrode tag.
11.3.2
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.
