11. BURNER INSTALLATION
11.1 Burner and supply pipe installation.
1.
Fit the burner unit to the convection box with two screws (See figure 12).
2.
Screw the gas tap bracket to the support bracket with the screw removed
previously (See figure 11).
3.
Connect the supply line to the appliance.
4.
Pressure check the installation pipework for gas soundness. In the United Kingdom
check in accordance with the current edition of BS6891. In the Republic of Ireland
refer to the current edition of I.S. 813 “Domestic gas installations”.
11.2 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.
11.2.1
Lighting the burner.
1.
Depress the control knob and rotate it SLOWLY anticlockwise to the PILOT / IGN
position. A 'click' will be heard as the integral piezo operates. A spark should be seen
between the electrode and pilot tip.
2.
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 ten seconds. When the control
knob is released the pilot flame should remain lit.
11.2.2
Operating the burner.
1.
When the pilot burner is operating properly, gradually turn the control knob
anticlockwise 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.
