General
A commercial heavy duty, fully modular, gas fired griddle / electric oven range using a thermostatic burner system on the griddle and
fitted with 3 bar even heat aluminised steel burners with full pilot and flame failure protection and piezo ignition to each burner.
All UK models and optional Non UK models are fitted with an overtemp device which isolates the gas supply to the burners should the
gas control system or thermostat malfunction, thus preventing overheating of the griddle.
The griddle uses a 20mm thick griddle plate with the option of either ribbed or chromed mirror plate options and is available in either
900mm or 1200mm griddle size.
With a heavy duty, high efficiency electric static or convection oven options, fitted with a 900mm, 6.5 kW electric static oven and a
6.6 kW Convection Oven created for compact modular kitchens. Both ovens are fitted with 4.5 kW bottom elements and 2.0 kW top
element. The Convection Oven is fitted with a 100 W oven fan motor.
The appliance is built to facilitate easy cleaning and maintenance with all parts being front accessible once the appliance is installed.

5.2 Fault Diagnosis
5.2.1 Pilot goes out when Pilot Knob is
Released
Pilot Flame Too Small
If pilot can be lit but the flame is too small to impinge on the
thermocouple, check gas pressure. If gas pressure is satis,
remove pilot injector from pilot burner and check for blockages
and / or correct sized pilot injector.
Thermocouple Faulty
Inspect thermocouple for build-up of carbon or food deposits on
the tip. Clean off any deposits, taking care not to scratch off
the aluminium coating on the tip of the thermocouple.
Check that the thermocouple tip is located in the pilot burner
flame zone. When pilot burner is lit, the flame should impinge
on the top 5mm of the thermocouple tip.
NOTE: Thermocouple should not touch the burner.
Check thermocouple connection to gas control is firm (loose
connections will cause resistance in millivolt circuit and result in
pilot outage).
If connection is good, disconnect thermocouple from the gas
control, light the pilot burner, and whilst holding the control
knob depressed, measure voltage between thermocouple
internal wire (refer figure 5.2.1) and earth (e.g. body of the gas
control). This should read approximately 30mV. If this reading
is less than 10mV then the thermocouple is faulty - replace
thermocouple.
Figure 5.2.1
Tip
Internal Wire
Gas Magnet Faulty
If thermocouple milli-voltage is above 10mV, and pilot still will
not hold, the gas magnet is faulty - replace gas magnet.
NOTE: Oven valves will require replacement if gas
magnet is faulty.
Short in High Tension Lead
If repeated operation of the piezo ignitor shows intermittent
sparking at the electrode, the lead should be traced to find area
of short. This can normally be visually seen as the spark arcs.
If the lead is shorting, replace the HT Lead, as the electrical
insulation strength of the lead may have deteriorated.
If the spark arc can be seen at the electrode insulator at the
pilot burner instead of at the electrode tip, the insulator
probably has a fracture and should be replaced.
Piezo Ignitor Faulty
If no spark at all can be generated, remove piezo ignitor and
hold close to the hob body, depress piezo ignitor and if a spark
cannot be generated to hob body the piezo ignitor is faulty and
should be replaced.

5.2.4 No Oven Temperature Control
Thermostat Faulty
With thermostat in ‘Off’ (vertical) position, heating indicator
should be ‘Off’. If heating indicator is ‘On’, thermostat is faulty
- replace thermostat.
Check the thermostat phial is in the correct position and check
for a broken capillary tube - replace thermostat if damaged.
Place an accurate digital thermometer probe in centre of oven.
Set thermostat to 180°C.
Close oven door and allow oven thermostat to regain
temperature. If temperature overshoots by 50°C and continues
to rise, switch ‘Off’ and replace thermostat.
5.2.5 Bottom Element Not Working
Element Faulty
With thermostat ‘On’ and heating, and energy regulator set to
minimum (‘Off’) position, check voltage across bottom element
terminals at right hand side of oven. If voltage is correct, check
current draw of element. If there is no current draw, element is
faulty - replace bottom element.
NOTE: Correct Bottom Element Current Draw:
220—240V: 9.4A ± 5%.
Alternatively, disconnect wires from element terminals and
check the resistance of the element. An open circuit indicates
that the element has failed.
Correct Element Resistance: 25.6 Ohms.
5.2.6 Fan Does Not Operate
Thermostat Faulty
With door closed and thermostat and heating switched ‘On’,
check voltage at Terminal 5 of the thermostat.
If no voltage, thermostat is faulty - replace the thermostat.
If voltage is correct, check wiring to capacitor and fan motor.
Fan Motor Capacitor Faulty
Ensure oven is isolated from power supply. Disconnect all wires
from capacitor. Briefly short across capacitor to ensure it is
fully discharged.
Using a multimeter, measure across capacitor terminals.
Resistance should start low and quickly increase to infinity
within 5 - 10 seconds.
If resistance does not increase at all, capacitor is shorted -
replace capacitor.
If capacitor is infinite resistance straight away then is open-
circuit - replace capacitor.
If resistance never goes very high, capacitor is leaky - replace
capacitor.
Energy Regulator Faulty
Check voltage between terminal P1 and terminal 4 of energy
regulator. If no voltage present, check wiring.
With switch in ‘Off’ position there should be no voltage at
Terminal 2 (open circuit between Terminal P1 and Terminal 2).
With control set to a LO to HI heat setting, Terminal 2 should be
switched ‘On’. If Terminal 2 not switched ‘On’, energy regulator
is faulty - replace energy regulator.
The above checks can be made with or without electrical supply
switched ‘On’, with electrical supply turned ‘On’, Terminal 2
element supply will cycle ‘On’ / ‘Off’ at different time ranges
dependent on control setting.
To check for correct energy regulator ‘On’ / ‘Off’ cycling,
electrical supply needs to be switched ‘On’.
With control set to full ‘On’ (HI) position, Terminal 2 (power to
element) should be ‘On’ continuously. With control set to
position 2½, Terminal 2 (power to element) should cycle ‘On’ for
approximately 15 seconds and ‘Off’ for approximately 30
seconds.
Lower settings will give longer ‘Off’ times and shorter ‘On’ times,
whilst higher settings will give shorter ‘Off’ times and longer ‘On’
times.
Top Element Faulty
With thermostat ‘On’ and heating, and energy regulator set to
maximum position, check voltage across top element terminals
at right hand side of oven. If voltage is correct, check current
draw of element. If there is no current draw, element is faulty -
replace top element.
NOTE: Correct Top Element Current Draw:
220—240V: 12.5A ± 5%.
Alternatively, disconnect wires from the element terminals and
check resistance of element. An open circuit indicates that the
element has failed.
Correct Element Resistance: 19.2 Ohms.
