2.4 CONNECTION TO ELECTRICITY SUPPLY
Not applicable to this appliance.
2.5 PRE-COMMISSIONING CHECK
After installation and assembly, the following checks
must be carried out to ensure satisfactory operation
of the unit. Failure to do this may result in damage to
the appliance or necessitate a service call for
rectification.
2.5.1 Gas Soundness
Turn on main gas supply and check soundness.
2.5.2. Burner Operating Pressure
Fit a pressure gauge to test point on burner inlet
supply. Turn on main gas cock and purge service
pipework of air. Light pilot then main burner as
instructed in User instructions. Adjust pressure at full
on rate (See Section 1.9)
An adjustable governor is provided for use on
NATURAL GAS MODELS ONLY. This is situated
behind the lower door. The pressure may be set by
removing the screwed cap and inserting a
screwdriver. Rotating the inner adjusting screw
clockwise will increase pressure whilst anti-clockwise
rotation will decrease it.
Adjustment on PROPANE MODELS must be made at
main regulator. No adjustment is provided on the unit.
2.5.3 Low Flame Setting
Upon completion of above, turn burner tap back to
low flame position (Mark 3) and check that pressure
corresponds with the following -
If adjustment is required, remove control panel and
turn low flame adjustment screw clockwise to reduce
pressure. (see Figure 2 below)

On completion, turn burner OFF. Remove pressure
gauge and replace test point screw.
2.5.4 Flame Failure Device
It is IMPORTANT that the pilot burner is kept clean
and properly adjusted. The frequency of cleaning will
depend on the prevailing conditions in the kitchen.
Should FFD fail to engage, the following points
should be checked. Details of access to individual
components can be found in Section 3 - Servicing.
1. Ensure gas supply to appliance is turned ON.
2. Check pilot gas supply to ensure there is no
stoppage or blocking of the connecting tubes and
pilot burner injector.
3. Check position of pilot flame in relation to
thermocouple. This should envelop and heat
10mm of thermocouple end . The thermocouple
end should be at centre of flame.
4. Ensure thermocouple is located firmly in the
seating on pilot burner. Take care not to
overtighten clamping screw retaining nut.
5. Check thermocouple connections to valve is clean
and that satisfactory contact is made. The nut
should be screwed, finger tight into valve and a
further sixth of a spanner turn (one spanner flat) to
secure. The connection MUST NOT BE
OVER-TIGHTENED as this may cause damage
to valve or thermocouple. No thread compound
should be used as this is an electrical connection.
6. Press burner tap knob IN, turn to ignition setting
and hold. Press igniter button fully in and release
it. Check resultant spark has lit pilot burner.
If electrode fails to spark, check both electrode
and igniter (see Section 3). If either component is
faulty, pilot may be lit with a taper.
Should pilot fail to light, press and release igniter
button once again. This operation should not be
attempted more than 4 times before turning gas
OFF and waiting at least 3 minutes before trying
again.
With pilot established, continue to hold tap knob
IN for a further 20 seconds then release. The pilot
should now remain lit.
Should appliance fail to respond to these checks
then a new FFD magnet unit or thermocouple will
require to be fitted.
2.5.5 Ignition
Having adjusted burner pressure, carry out lighting
procedure to check smooth ignition of pilot and main
burner.
Important Note
It is essential the above checks are carried out before
unit is put into service. Failure to do so may result in
damage to appliance or necessitate a service call.
