Burner And Supply Pipe Installation; Lighting The Fire - Valor 639 Installer's Manual

INSTALLER'S GUIDE

7. BURNER AND SUPPLY PIPE INSTALLATION

A nut and olive is provided for an 8mm-pipe inlet connection directly to the gas
control. The elbow can be rotated to allow a connection from any direction. The
elbow 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.
Pressure check the installation pipework for gas soundness in accordance with the
current edition of BS6891.
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.

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.
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.
