Never directly connect a ventilation system to
the appliance flue outlet.
Installation must allow for sufficient flow of
fresh air for the combustion air supply.
Installation must include adequate ventilation
means, to prevent dangerous build up of
combustion products.
2.1 BEFORE CONNECTION
Check the type of gas, the specified operating
pressure and the hourly consumption. This
information is clearly stated on the rating plate
which is located to the left of the control panel.
When checking pressure, be certain that all
other equipment on the same gas line is
turned on.
Check the gas supply characteristics for the
type of gas, supply line pressure and capacity.
A regulator is supplied with appliances for use
on natural gas. (These should be fitted only
by a licensed gas fitter).
The operating pressures for the respective
gases are:
Natural (G20) 1.0kPa / 10 mbar (4.0" WG)
Propane (G31) 3.7kPa / 37 mbar (14.8" WG)
The pressure test point for measurement of
correct appliance operating pressure is
located at the hob left front corner.
2. INSTALLATION
On Propane gas the pressure is controlled by
the supply pressure.
On Natural gas the pressure is controlled by
the appliance’s regulator, which can be
adjusted to obtain correct operating pressure.
2.2 ASSEMBLY
1) Tilt the oven onto its LH side and fit both
the right front leg and right rear roller in
the corresponding leg rings.
2) Secure each one in place with the screw
attached.

secure the front LH leg and rear LH roller
as described in (1) and (2).
4) Check that all are in place and tightened
firmly.
5) Adjust the two front feet to make the oven
steady and level.
Gas Connection
1) The gas regulator is supplied only for
connection to a Natural gas supply.
2) Units for use on Propane gas do not have
a regulator supplied, as the pressure is
controlled by a supply regulator at the
Propane gas supply tank.
3) It is important that adequately sized piping
runs directly to the connection joint on the
unit, with as few tees and elbows as
possible to give maximum supply volume.
4) An accessible shut-off valve must be fitted
on the supply line before the connection
joint and pressure regulator.
5) A suitable jointing compound which resists
the breakdown action of LP Gas must be
used on every gas line connection, unless
compression fittings are used.
6) Check all connections for leakage.

Revision 3/F3601
SAFETY SYSTEM
The purpose of the safety system is to shut off
the flow of gas if the flame goes out. It is
comprised of the flame itself, the
thermocouple, and the flame failure gas valve.
The burner flame is lit by holding in the gas
control knob, which in turn temporarily pushes
the plunger inside the safety valve open and
allows gas to flow through. Once the burner
is lit, the thermocouple will begin to generate
millivolts (after about 10 to 30 seconds of
being heated) and will energize the
electromagnet inside the gas valve. Once
energized the electromagnet holds the
plunger inside the gas valve in the open
position. The plunger has to have been
pushed all the way in for the electromagnet to
be able to hold it in place. If the burner flame
goes out for some reason, the thermocouple
will cool after about 10 to 30 seconds and
stop generating millivolts. The electromagnet
will then de-energize, and the plunger will
snap shut, cutting off the flow of gas.
Detail of each component in the safety system
is explained below.
THERMOCOUPLE
The thermocouple is a device that generates
electricity when heat is applied to the tip.
The tip of the thermocouple is located in the
burner flame, and the nut at the other end of
the thermocouple screws into the back of the
gas valve. Inside the copper tubing is a wire
which is joined at the tip but insulated from the
rest of the tubing. These two parts (the
copper tubing and wire) make up the "wiring"
for an electrical circuit. When these two
dissimilar metals, wire and tip, are heated an
electrical voltage is produced. This type of
thermocouple generates between 7 and 30
millivolts when heated in the pilot flame.

3.2 EXPLANATION OF CONTROL
SYSTEM

position, stopping the flow of gas.
Millivolts are provided to the electromagnet by
the thermocouple (not shown) which
generates millivolts when heated. The
thermocouple screws into a fitting at the back
of the gas valve to make an electric
connection. By pressing in the gas control
knob, the plunger can be temporarily held
open while lighting. There's two reasons for
this; gas has to flow through the safety valve
to make it possible to light the burner, and
secondly the plunger has to be pushed all the
way in for the electromagnet to hold it in. I.e.;
the electromagnet is strong enough to hold
the plunger in once there, but is not strong
enough to pull it in by itself. Sometimes a
problem with the flame not staying lit after
releasing the button can be attributed to not
pushing the plunger all the way in.
The Troubleshooting Guide (Section 5) should
be used to identify any incorrect operation.
On correct identification of the operating fault
the Troubleshooting Guide will make
reference to the corrective action required, or
refer to the Fault Diagnosis section and/or
Inside the body of the gas valve is an
electromagnet connected to a spring loaded
plunger. When the electromagnet is
energized, it holds the plunger in, allowing gas
to flow through the valve. When the
electromagnet is
de-energized, the plunger snaps to the closed

4. MAINTENANCE
EXTERIOR
Clean with detergent. Baked on deposits or
discoloration may require a good quality
stainless steel cleaner or stainless steel wool.
Always apply cleaner when the unit is cold
and rub in the direction of the grain.
INTERIOR
Do not use wire brushes, steel wool or other
abrasive materials. Clean the oven regularly
with a good quality domestic oven cleaner.
Once a week, remove and clean built up
grease etc. from the oven racks and bottom
spill over cover.
MAINTENANCE
To achieve the best results cleaning must be
regular and thorough, and all controls and
mechanical parts checked and adjusted
periodically by a competent serviceman. If
any small faults occur, have them attended to
promptly. Don't wait until they cause a
complete breakdown. It is recommended that
a service check is conducted every 6 months.
NOTE:
The gas supply must be OFF during
cleaning or maintenance.
4.1 CLEANING
It is recommended that a service check is
conducted every six months.
1) Visual check of the pilot and main burners,
to see if correct size flame, and colour on
main burner.
2) Check the gas pressure with a manometer
(water gauge).
3) Check and clean inside control area,
making sure that all connections are
secure.
4) Check condition of the gas supply pipe,
regulator and fittings.
5) Check for gas leaks at all fittings inside
and outside the unit.
6) Check gas control operation, smooth to
operate. Regrease gas controls if
required (refer service section).
7) Check thermocouple operation, burner
should hold quickly after lighting, replace
thermocouple if required.
8) Adjust the door ball catches. Check the
striker plates for wear.

Revision 3/F3601
6.1 FAULT DIAGNOSIS
Short in high tension lead
If repeated sparking of the piezo shows
intermittent sparking at the electrode, then 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 the best
solution is to replace it, 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, then 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.
NOTE:
If piezo ignition fails, the pilot can be
manually lit in the interim until the piezo circuit
is repaired. A standard taper torch or
matches/lighter can be used for manual
back-up ignition.
6.1.3 PIEZO IGNITOR NOT SPARKING
6.1.1 HOB BURNER GOES OUT WHEN
KNOB RELEASED
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 thermocouple.
Check that the thermocouple tip is in the
flame zone of the burner. When the burner is
lit, the flame should impinge on the top 5mm
of the thermocouple tip.
NOTE:
The 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 flame
outage).
If connection is OK, then disconnect the
thermocouple from the gas control, light the
burner, and whilst holding the control knob in,
measure voltage between the thermocouple
and earth (e.g. the body of the gas control).
This should read approximately 30mV. If this
reading is less than 10mV then the
thermocouple is faulty—replace.
Gas magnet faulty
If thermocouple milli-voltage is above 10mV,
and the burner still will not hold, then the gas
magnet is faulty - replace.
6.1.2 PILOT GOES OUT WHEN CONTROL
KNOB IS RELEASED
Pilot flame too small
If pilot can be lit but the flame is too small to
impinge on the thermocouple, then check the
gas pressure. If ok, remove pilot injector from
pilot burner and check for blockages and/or
correct size.
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 thermocouple.
Check that the thermocouple tip is in the
flame zone of the pilot burner. When the
burner is lit, the flame should impinge on the
top 5mm of the thermocouple tip.
NOTE:
The 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 OK, then disconnect the
thermocouple from the gas control, light the
pilot, and whilst holding the control knob in,
measure voltage between the thermocouple
and earth (e.g. the body of the gas control).
This should read approximately 30mV. If this
reading is less than 10mV then the
thermocouple is faulty—replace.
Gas magnet faulty
If thermocouple milli-voltage is above 10mV,
and the pilot still will not hold, then the gas
magnet is faulty - replace.

checks should be made before assuming
the thermostatic control calibration is
faulty.
a. Check burner pressure.
b. Check the MAXIMUM flow adjustment
setting on control valve (refer 6.5.4).
c. Check the MINIMUM flow adjustment
setting on control valve (refer 6.5.5).
