Lighting the Open Burners

These hobs are fitted with individual standing pilots for each open burner which allows main burners
to be turned 'ON' - 'OFF' without having to manually re-light burner each time that it is turned 'ON',
as burner will automatically light itself off the pilot burner.
Flame Failure Protection is incorporated for each burner by way of a thermo-electric system which
will shut off gas supply to that burner in the event that burner goes out, so that un-burnt gas is not
expelled.

a. Select burner required, depress and turn the gas control knob anti-clockwise to ‘PILOT’ position.
b. Hold gas control knob depressed and manually light pilot burner.
c. Release gas control knob after approximately 10-20 seconds after lighting pilot burner.

b. To turn 'OFF' 'PILOT', depress and turn gas control knob clockwise back to ‘OFF’ position. 'PILOT'

burner will extinguish.

Oven Pilot Ignition

! IMPORTANT

DO NOT USE aluminium foil or trays directly on cast iron sole plate(s). NEVER block or cover
openings on each side of sole plate(s).

This oven is fitted with a pilot as a standard option and flame failure protection, which is incorporated by
way of a thermo-electric system for the main burner. Flame failure protection will shut off gas supply to
burner in the event that pilot burner goes out, so that un-burnt gas is not expelled.

Operation

Oven - Main Burner / Thermostat

1. Ensure oven door is closed.

2. Turn ‘ON’ electrical power at mains supply, (white) power indicator light will illuminate on oven
control panel.

3. With pilot burner alight, depress and rotate oven gas control knob to 'Main Flame' position. (This
puts gas valve in 'Stand-By' position and control of main burner is now carried out through oven
thermostat control).

4. Turn oven thermostat to desired oven temperature setting required, this will regulate gas supply to
oven main burner.

5. Oven fan will start up and oven main burner will ignite.

6. Amber heating indicator light will show that oven main burner is ‘ON’ and oven is heating. When
amber heating indicator light goes out, oven has reached pre-selected temperature, burner will cycle
‘OFF’.

Oven Fan

1. Fan is operational only when oven thermostat is set to a temperature. Fan is controlled by a
microswitch which in turn is controlled by opening and closing oven door. Oven fan is operational
only with oven door closed.

Turning the Oven to ‘Standby’ (Pilot ‘ON’ Only)

1. To turn ‘Off’ oven main burner / heating, set oven thermostat to '0' temperature position, this will
turn oven main burner ‘OFF’, but will leave oven pilot burner ‘ON’.

2. In this position pilot burner will remain alight, but oven main burner will not operate until thermostat
control knob is set to a temperature.

3. If oven pre-heating is required, set thermostat control knob to temperature 190°C and allow 20
minutes before cooking in oven to allow oven to warm up.

Oven ‘Shut-Down’

1. To ‘Shut Down’ oven, turn oven thermostat to ‘0’ position, oven main burners will go out.

2. Turn gas control valve to 'OFF' position and this will extinguish pilot burner. (To relight pilot burner,
refer to ‘Oven Pilot Ignition’ above).

3. Turn ‘OFF’ electrical power at mains supply, (white) power indicator light will extinguish.

NOTE: If main burner has recently been turned 'OFF', should you wish to re-light oven, the

interlock will not allow gas valve to be turned to main burner position until interlock has
reset (Approximately 1 minute). DO NOT FORCE GAS VALVE TO MAIN BURNER POSITION
UNTIL INTERLOCK HAS RESET, as this will damage gas control valve.

IMPORTANT:

Should any abnormal operation like;

- ignition problems,

- abnormal burner flame,

- burner control problems,

- partial or full loss of burner flame in normal operation, appliance requires IMMEDIATE
service by a qualified service person and should not be used until a service is carried out.

Griddle Plate Cleaning

It is recommended that a flat blade scraper is used
to clean the griddle surface, these are not supplied
with griddle but may be purchased separately.
Refer to 'Replacement Parts List' at rear of this
manual.

T

HE BLADES FITTED TO THE SCRAPER TOOL ARE EXTREMELY SHARP

Always ensure that even pressure is
applied over whole surface of scraper tool
when using on flat surface of griddle, to
prevent scoring of griddle surface.

NEVER bang sharp edge of scraper tool on
flat surface of griddle as this will damage
the griddle and invalidate the warranty.

AND ARE TO BE USED WITH CARE.

Warning

Caution

1. Clean griddle plate surface thoroughly with a
scraper tool and brush off any deposits with a
soft bristled brush.

2. Stubborn or accumulated carbon deposits can
be removed with a griddle stone or a scotch
bright pad.

3. Wipe down griddle surface with a cloth and
then clean with hot soapy water and a soft
bristled brush. Dry thoroughly with a dry cloth.

4. Occasionally bleach griddle plate with vinegar
when plate is cold.

5. Empty grease tray and wash with warm soapy
water. Dry thoroughly with a dry cloth. Refit
grease tray.

6. Briefly turn ‘On’ griddle until griddle plate is
dry.

7. Spread a thin smear of cooking oil over griddle
plate to form a protective film.

Although this section covers most common problems reported, you may encounter a problem not covered
in this section. In such instances, please contact your local authorised service agent who will make every
effort to help you identify and resolve the problem. Please note that the service agent will require the
following information:-

 Model Code and Serial Number of appliance. (Both can be found on the Rating Plate

located on the appliance).

Fault Possible Cause Remedy

Pilot won’t light. No gas supply.

Blocked pilot injector.

Pilot goes out when gas control
knob released.

Main burner will not light. Incorrect supply pressure.

Releasing knob before thermo­couple has heated.

Pilot flame too small.

- Gas pressure too low.

- Partially blocked pilot injector.
Thermocouple connection to gas

control is loose or faulty.
Thermocouple faulty.

Electromagnet in rear of gas con­trol unit is faulty.

Faulty gas control.

Ensure gas isolation valve is turned
on, and bottles are not empty.

Call service provider.
Hold knob in for at least 20

seconds following ignition of pilot.
Clean or replace pilot injector.

Tighten thermocouple connection.

Check thermo couple is producing
between 20-30mV.

Inspect and replace if not in good
working order.

Call service provider.

Call service provider.
Call service provider.

Piezo Ignition spark is being
generated but not sparking
from ignition electrode to pilot
burner hood. (On Griddle and
Oven Options).

NOTE: Components having adjustments protected (e.g. paint sealed) by the manufacturer, are only

to be adjusted by an authorised service agent. They are not to be adjusted by an
unauthorised service person.

HT lead damaged or broken.
Check ignition electrode is not

cracked and is correctly
positioned.

Piezo igniter faulty.

19

Repair or replace the HT lead.
Re-position or replace ignition

electrode.

Replace piezo igniter.
Call service provider.
