INTRODUCTION

IMPORTANT

This appliance is designed for cooking food, any other use is incorrect and dangerous. Failure
to install the appliance correctly or improper use could invalidate any warranty or liability claims
and lead to prosecution.

This appliance must be installed in accordance with the local, national and European
regulations in force. Particular attention shall be given to the requirements regarding ventilation.
Read the instructions before installing or using the appliance. The appliance MUST be installed
by an approved competent person.

Our policy is one of continuous development and improvement. Specifications and illustrations
may change subsequent to publication.

Provision of Ventilation
The use of a gas cooking appliance results in a production of heat and moisture in a room in
which it is installed. Ensure that the kitchen is well ventilated: keep natural ventilation holes
open or install a mechanical ventilation device, (mechanical extractor hood).
Prolonged intensive use of the appliance may call for additional ventilation, for example opening
a window, or more effective ventilation, for example increasing the level of mechanical
ventilation where present.
The room containing the cooker should have an air supply in accordance with local and
national/European standards.

Position
This appliance must be positioned free from draughts, which may affect the combustion, and in
a manner that will prevent the accumulation of unburnt gas. When in use ensure that air vents
are not inadvertently blocked or shut off.

Before using the appliance for the first time, remove any surface protection
film, ie plastic coating. Clean all surfaces with hot soapy water to remove any
residual protective covering of oil and rinse carefully.

OPERATION

WARNING

IMPORTANT

Burner Operation

The burners on the appliance have fixed aeration and no adjustment is required. The burners
should flame as follows:-

Propane - The flames should burn quietly with a blue/green colour with no sign of yellow tips.
Butane - Normally on initial lighting, a small amount of yellow tipping will occur and then

• When cooking, young children should be kept away.

• Glass lids may shatter when heated. Turn off all burners before shutting

the lid.

• Spillage on the lid surface should be removed before opening the lid

slightly increases as the burner heats up.

• Series 330 - will support 200mm Ø pans on the outer burners and

180mm Ø pan on the central burner – see Fig. 2

• Series 340 & 345 will support 3 x 200mm Ø pans – see Fig. 2

• Avoid old or misshapen pans as these may cause instability.

• The lid must be opened fully prior to using the hotplate burners.

1. Ensure gas cylinder/supply is connected and turned on. In the event of a gas smell turn off at

gas cylinder/mains and contact supplier.

2. Flame supervision: Each burner is controlled individually and is monitored by a

thermocouple probe. In the event of the burner flames being accidentally extinguished, turn
off the burner control and do not attempt to re-ignite the burner for at least one minute.

3. To light: Push in the control knob and turn to full rate – see Fig.1. Hold a lighted match or

taper to the burner and push the control knob in and hold. It is necessary to hold the knob
depressed after the burner has ignited for approximately 10 - 15 seconds, to allow the
thermocouple probe to reach temperature, before releasing the knob. Should the flame go
out when the knob is released, the procedure should be repeated holding the knob
depressed for slightly longer.

4. For models fitted with optional Spark Ignition the procedure is similar:-

Models with Auto Spark Ignition – pushing the control knob automatically starts the
spark ignition circuit . To light the burner follow the procedure in (3) above except the
burner is automatically ignited.
Models with Manual Spark Ignition – follow the procedure in (3) above, except that the

burner can be ignited by depressing the ignition button located on the fascia.
If the burner has not lit within 15 seconds the control knob should be released and the
burner left for at least 1 minute before a further attempt to ignite the burner.

5. For simmering, turn the knob further anti-clockwise to the low rate position.

6. To turn off: Turn the control knob until the line on the control knob is aligned with the dot on
the control panel. Always make sure the control knob is in the off position when you have
finished using the hotplate burners.

DO clean the appliance regularly.

DO remove spills as soon as they occur.
DO check that controls are in the off position when finished.
DO NOT allow children near the appliance when in use. Turn pan handles away from the

DO NOT allow fats or oils to build up in the base of the hotplate.
DO NOT use abrasive cleaners or powders that will scratch the surfaces of the hotplate.
DO NOT under any circumstances use the appliance as a space heater.

LEAKS

If a smell of gas becomes apparent, the supply should be turned off at the cylinder
IMMEDIATELY.
Extinguish naked lights including cigarettes and pipes. Do not operate electrical switches. Open
all doors and windows to disperse any gas escape. Butane/Propane gas is heavier than air;
any gas escaping will therefore collect at low level. The strong unpleasant smell of gas will
enable the general area of the leak to be detected. Check that the gas is not escaping from an
unlit appliance. Never check for leaks with a naked flame; leak investigation should be carried
out using a leak detector spray or soapy solution.

The Glass lid has the tendency to snap shut towards the end of lowering.
This is caused by the travel lock action of the hinges as it is activated. Make
sure all fingers are removed from appliance when closing the lid.

INSTALLATION
REGULATIONS AND STANDARDS

In your own interest of safety this appliance must be installed in accordance with the local,
national and European regulations in force. Particular attention shall be given to the
requirements regarding ventilation. Read the instructions before installing or using the
appliance. The appliance MUST be installed by an approved competent person.

Failure to install the appliance correctly could invalidate any warranty or liability claims and lead
to prosecution.

VENTILATION

This appliance is suitable for installation into Holiday Homes, Touring Caravans and Boats. In all
cases the national standards with regard to ventilation for the particular vehicle into which the
appliance is to be installed must be adhered to.
The European Standard EN1949 - "Specification for the installation of LPG systems in leisure
and other road vehicles", specifies that all appliances be installed in accordance with the
manufacturers instructions, including the adequate provision to avoid the accumulation of un­burnt gases. We recommend a vent in the floor (minimum=130mm2 , maximum=3850mm2)
venting to the outside, to avoid the accumulation of un-burnt gases.

LOCATION OF APPLIANCE

This appliance maybe installed in a kitchen/kitchen diner but NOT in a room containing a bath or
a shower. LP gas appliances must not be fitted below ground level. e.g. in a basement.

POSITION

A direct distance of 200mm must exist between the edge of the burner and combustible material
unless protected by a layer of non-combustible material - see fig. 3. For models with a glass lid,
the distance to the rear of the appliance can be reduced to 110mm.

All combustible materials such as curtains and shelves must be kept well clear of the appliance.
Any fitments such as a cupboard above the appliance must have a minimum clearance of
500mm between the fitment and the top of the pan support.

This appliance must be positioned free from draughts, which may affect the combustion, and in
a manner that will prevent the accumulation of unburnt gas. When in use ensure that air vents
are not inadvertently blocked or shut off.

The underside of the appliance must be shielded. It is recommended the shield is fabricated
from non-combustible material, but if the enclosure is manufactured from combustible material,
a minimum air space of 100mm must exist between the material and the lowest part of the
appliance. THIS AIR SPACE MUST BE WELL VENTILATED
