this to seal any holes in the rear and inner sides of the convection box. DO NOT tape
over the large holes in the top of the convection box.
11. BURNER INSTALLATION
11.1 Burner and supply pipe installation.
1. Fit the burner unit to the convection box with two screws (See figure 15).
2. Align the hole near the bottom of the control linking bar with that in the control pivot
bracket. Join them with the screw removed previously (Use a screwdriver - do not
leave as finger tight only).
3. Check that the control linkage bar does not interfere with the appliance cable
retention nuts or wires.
4. Connect the supply line to the appliance.
5. 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. If closed, open the isolating valve at the inlet ‘T’ connector.
2. Depress the control knob as far as it will go and hold in this position (See section
7, figure 12). This should close the ignition circuit and (now that the gas is connected)
simultaneously open the gas tap allowing the gas to flow to the pilot.
Wait a few seconds while the air is purged. The electronically generated sparks
should light the pilot and the burner. There may be a delay of up to four seconds
between the pilot lighting and ignition of the gas at the main burner. This is normal
and is due to the time required to fill the main burner compartment with sufficient gas
for ignition. Keep at this position for a further 10 seconds to allow the pilot flame to
stabilise.
3. Release the knob. The knob should automatically spring up to the low heat
position. If for any reason the slider control does not spring up, raise the slider to the
upmost position and investigate why the slider is not operating correctly.
11.2.2 Operating the burner.
1. When the burner is operating properly, gradually lift the control slider. The burner
flames should gradually increase. You should feel some resistance when the slider
control reaches the maximum burner flame position. Lifting further until the control
slider comes to a stop should then turn the burner and pilot off. If the above checks
are satisfactory, continue with the installation. If not, check the control and ignition
circuitry and components as described in the servicing section of this manual.
