10. BURNER INSTALLATION
10.1 Burner and supply pipe installation.
1. Fit the burner unit to the hotbox using the two screws removed previously
2. Connect the supply line to the appliance.
3. If closed
,
open the isolating valve at the inlet ‘T’ connector.
4. Turn on the gas supply and pressure check the installation pipework for gas
soundness. In the United Kingdom check in accordance with the current edition of BS
6891. In the Republic of Ireland refer to the current edition of I.S. 813 “Domestic gas
installations”.
10.2 Lighting the burner.
1. If closed, open the isolating valve at the inlet ‘T’ connector.
2. Depress the control pivot plate as far as it will go and hold in this position (See
section 6, figure 9). 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. The pilot should then light the main burner at its low setting.
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.
10.3 Operating the burner.
1. When the burner is operating properly, gradually lift the control pivot plate upward.
The burner flames should gradually increase until the control pivot plate / control knob
is nearly at its highest position. You should feel some resistance when the control
pivot plate reaches the maximum burner flame position. Lifting further upwards until
the control pivot plate comes to a stop should then turn the burner and pilot off. When
the above checks have been completed close the isolating valve on the inlet ‘T’
connector. 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.
10.4 Inlet pressure check.
The appliance is pre-set to give the correct heat input
at the inlet pressure shown in section 2 of this
manual. No adjustment is necessary.
1. Check the inlet pressure by fitting a pressure
gauge at the test point. The test point is on the inlet
‘T’ connector (See figure 21). Check the pressure with
the appliance alight and set at maximum output.
2. After checking, turn off the appliance. Remove the
pressure gauge and replace the test point sealing
screw.
