Gas supply requirements
This appliance should be fitted by a Corgi registered fitter. The installation must comply
with Gas Supply Regulations 1972 and the relevant codes of practice.
CDA are not legally able to provide any assistance in the installation of gas appliances
except to Corgi registered installers. Any Corgi registered fitter requiring help must pro-
vide name, address and registration number.
Information supplied will be validated before help is provided.
This appliance is suitable for conversion to liquid petroleum gas. A kit should be
available from the place of purchase. Do not attempt to fit the kit yourself.
If installation is to be carried out using a flexible connector (to BS669), then the
following points must be adhered to:
Note: The gas installation pipes and the final connection to the appliance connecting
pipe shall be sufficient size to maintain the heat output of the appliance as specified
under installation.
1. The appliance flexible connector should not be subject to undue forces, either in
normal use whilst being connected or disconnected.
2. The appliance flexible connector should not be subject to excessive heat by direct
exposure to flue products or by contact with hot surfaces.
Note: The flexible connector must be able to withstand temperatures up to and
including 95°C.
3. The socket into which the plug of the appliance flexible connector fits should be
permanently attached to a firmly fixed gas installation pipe and positioned such that
the hose hangs freely downwards.
4. The appliance flexible connector should be positioned such that it will not suffer
mechanical damage; eg abrasion from the surrounding kitchen furniture which may
be moved in use, such as a door or drawer, or by being trapped by a stability
device.
5. The plug-in connector should be accessible for disconnection after moving the
appliance.
6. After connecting to the mains, check that the couplings are correctly
sealed, using soapy solution, but never a naked flame.

Ventilation
All rooms are required to have a window which can be opened or the equivalent.
Some rooms will also be required to install a permanent vent in addition to a window
(see table below).
This unit must not be used in a room with a volume of less than 5m3.
Room Volume Air vent necessaly (effective area)
5 m3to 10 m350 cm2
Greater than 11 m3No air vent necessary
A room 5 m3to 10 m3with a door No permanent air vent
opening to the outside necessary
The above requirements allow also for use of a gas hob but if there are other fuel
burning appliances in the same room, BS5440: 1976 should be consulted to
determine the necessary air vent requirements.
The oven is designed to fit into a cabinet of 600 mm width.
The oven can be built in or built under the kitchen units, but you must ensure that it is
properly ventilated.
In the diagram the built in oven is ventilated by means of a space at the top of the
kitchen cabinet. There are many other methods of ventilating your oven.
Consult a qualified engineer for advice.
IMPORTANT: If the oven is being installed into a built under oven housing unit ensure
that the front rail at the top of the unit is not installed as it will restrict ventilation.

6
How to install your oven
Ensure that air can flow freely around the housing area.
If the oven is being installed into a fully enclosed built under oven housing
unit it may be necessary to cut a small slot in the top of the plinth fitted under
the unit. Cut a section 400 mm wide and a minimum of 1 5 mm high to allow air to
pass under the unit.
Failure to allow adequate ventilation to the appliance may
result in over heating or damage to adjacent units.

Lift the oven carefully into position on the shelf, taking
care NOT to lift it by the door handle. If you lower the
oven door, you will see 4 screw holes, 2 on each side
of the oven.
The oven should then be secured to the housing by
fitting screws into these holes.
Remember the housing should not be free standing
but secured to the wall and/or
adjacent fittings.

REGULATION OF THE MINIMUM FLAME
(FOR FITTERS USE ONLY)
NOTE: The flame has been regulated for use with Natural Gas, however, when
converting to L.P.G. the flame may need adjusting.
Turn the thermostat to the maximum setting and pre-heat the oven, without grill pan
and base plate, for approximately ten minutes, turn the control to the 125 position.
Remove the knob and adjust the thermostat by-pass screw (Fig. 6) to obtain a short
sharp stable flame. (The flame is visible through the holes in the oven base).
Check that moving the control knob from the maximum flame position to the 125
setting, or rapidly opening and closing the oven door does not make the flame go
out.

Because of different gas mixtures in the distribution system, you may have flames with
too much or too little air. In such cases, loosen the screw and move the air ring to
close or open the air flow, until the regular flame is obtained (fig. 7).
Standard position of the air ring.
Natural Gas: Positioning the indicator line of the air ring to the symbol N printed on
the burner.
L.P.G.: Fully open the air ring.
Warning: The regulation of the flames must only be carried out by a Corgi registered
fitter.

Locate the wire side frames as indicated in Fig. 8.
Slide in, on the guides, the shelf and the tray etc. (Fig. 9).
The rack must be fitted so that the safety catch, which stops it sliding out, faces the inside
of the oven (Fig. 9).
Before using the oven for the first time, we recommend that you clean it with soapy
water, rinse carefully and heat for 30 minutes at maximum temperature.
A slightly unpleasant smell may be produced, caused by grease remaining on the oven
elements from the production process.

Figure 10
Figure 11
Lighting of oven burner
The thermostatic tap controlling the gas supply to the burner is equipped with a safety
device which automatically stops the gas flow in case of flame extinction. The tempera-
ture is constantly maintained on the set value.
The electric ignition starts up by pressing the thermostat knob.
A safety device prevents the electric ignition from functioning when the oven
door is shut.

12
C. Timer
The timer can be set to a maximum of 60 minutes. Turn the dial clockwise to the maxi-
mum setting of 60 minutes then turn it anti-clockwise until it reaches the desired time.
When the set time expires the timer bell will sound.
NOTE:
The oven will not switch itself off at the end of the timed period.
Safety devices
For safety reasons, it is not allowed to use the oven burner and the electric grill togeth-
er, at the same time.
The electric grill only operates when the oven thermostat control knob is on
position ●(out), as:
– when the oven burner is alight a safety device stops the ignition of the electric grill .
–
if the electric grill is on, the same safety device cuts off the element if the oven ther-
mostat control knob is turned on.
1 - Max Grill with the door closed. Set the temperature to the desired setting
which can be varied between 1 and max. Before using the grill, pre-heat
for about 5 minutes.
Position the grill pan on the highest shelf position and check continually
as food could easily burn. The indicator light will cycle with the grill ele-
ment.
Grill with the knob set to Max position for maximum 15 minutes, then
to position 4for maximum 15 minutes.
Caution: the oven door becomes very hot during operation.
Keep children well out of reach.
B. Grill and Light Selector
The light will switch on automatically while grilling and can be selected
when using the oven.

Cooking guide
Your gas oven is a newly designed oven which incorporates an indirect burner located
under the oven base plate.
If you have previously been used to cooking with gas you may need to slightly alter
your cooking methods. The bottom of the oven is hot and is ideal for browning the
underside of shallow pastry dishes and pizzas. Other items should be cooked nearer
the top of the oven.
When baking cakes, scones etc on more than one shelf the best results will be
achieved by swapping the shelf positions over half way through the cooking process.
SAFETY
NEVER allow fat to build on the oven base.
As with all ovens, clean and empty fat regularly from the trays and oven base to avoid
the possibility of fat fires.
The oven contains a cooling fan at the top of the appliance which forces cool air over
the fascia panel when the oven reaches a set temperature to prevent it from becoming
too hot.
The fan will continue to operate after the oven has been switched off, until the
appliance cools down. However, the oven door can become hot - keep children away
from this appliance.
NEVER place anything on the bottom of the oven.
Do not line the oven walls with aluminium foil.
Do not place baking trays or the drip tray on the base of the oven chamber.
USE OF THE GRILL
Preheat the oven for about 5 minutes with the door closed.
Introduce the food to be cooked, positioning the rack as close to the grill as possible.
The dripping pan should be placed under the rack to catch the cooking juices and
fats.
Grill with the knob set to Max position for maximum 15 minutes, then to position 4
for maximum 15 minutes.
Do not grill for longer than 30 minutes at any one time.
Caution: the oven door becomes very hot during operation. Keep children
well out of reach.
