11.1
Locate the two lugs at the top of the front surround in the slots in the
convection box hood. Swing the bottom of the surround sides back against the
convection box and lower the surround so that the lugs are fully seated in the
slots in the convection box hood.
11.2
Refit the two screws to secure the surround sides to the convection box
brackets
.
11.3
Connect the supply line to the appliance.
Unless the supply pipe connection is from the left front side, the supply pipe
will have to be formed to avoid various components below the burner. An
installation template is supplied which contains a diagram for bending this
supply pipe.
11.4
Pressure check the installation pipework for gas soundness in accordance
with the current edition of BS6891.
Do not use leak detection sprays on this
appliance. Sprays may affect the operation of electrical components. Keep all liquid
detection fluids clear of electrical components.
A long brush may be required to
reach some joints.
11.5
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
.
11.5.1
Switch on electrical power supply. The red indicator light at the left side
of the burner should be on.
11.5.2
If closed, open the isolating valve at the inlet elbow.
11.5.3
Press and hold in the “on” switch. Within two seconds, the Fan motor
should start and the indicator light should go out.
11.5.4
Release the “on” switch. The fan should continue to run.
11.5.5
Depress the control knob and turn anticlockwise partially towards the
“PILOT/IGN” position until some resistance is felt. Keep depressed at this
position to purge air from the system then, while keeping it depressed, turn
fully to the “PILOT/IGN” position. A spark should be generated at the pilot
while turning. The spark should ignite the pilot.
11.5.6
When pilot ignition has been achieved, keep the control knob depressed
for approximately ten seconds to allow the thermocouple probe to warm up and
then release it. If the pilot does not remain alight, ensure that the air has been
purged, that the pilot orifice is clear and that the thermocouple connections are
sound. Replace the pilot unit if necessary (see servicing section of this manual).
11.5.7
When the pilot is alight and stable, partially depress the knob and turn to
“LOW”. 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.
11.5.8
With the burner at “LOW”, partially depress the control knob and
gradually turn it anti-clockwise. The burner flames should gradually increase
until the knob reaches the “HIGH” position.
When the above checks have been
completed partially depress the control knob and turn to “OFF”.
