Safety Instructions
IMPORTANT
PLEASE READ INSTRUCTIONS FULLY BEFORE USE
THIS APPLIANCE IS ONLY FOR PROFESSIONAL USE AND MUST ONLY BE USED BY QUALIFIED
PEOPLE.
Attention should be drawn to the fact that parts of this unit by necessity, will get VERY HOT,
and will cause burns if touched accidentally. Therefore, it is the responsibility of the
supervisor or equivalent to provide SUITABLE PROTECTIVE CLOTHING for the user.
THIS APPLIANCE MUST BE FITTED AND TESTED BY A REGISTERED FITTER BEFORE USE.
The unit should be installed in compliance with the INSTALLATION INSTRUCTIONS and the
NATIONAL REGULATIONS in force at the time. Particular attention should be paid to the Gas
Safety (Installation and Use) Regulations and the Health and Safety at Work Act.
All commercial gas catering equipment is recommended to be mounted below an extraction
canopy. Please consult a ventilation engineer or refer to Guidelines DW172 to calculate the
ventilation requirements for cooking areas containing different pieces of gas catering
equipment.
Each appliance requires a flow of fresh air for combustion. Under no circumstances should
air vents on the appliances, or air vents installed by the fitter in the room of the appliance to
supply combustion air, be altered or omitted in any way.
To prevent shocks, all appliances whether gas or electric, must be earthed.
ANY GAS CONVERSIONS NEEDED TO BE MADE TO THE PRODUCT MUST BE CARRIED OUT
BY A GAS SAFE REGISTERED ENGINEER
To avoid scratching the highly polished exterior surface of this equipment whilst in transit,
the protective film on the exterior surfaces has NOT been removed.
It is IMPORTANT that this protective film is peeled off before the equipment is used.

Installation Instructions
ALL APPLIANCES MUST BE FITTED AND OR CONVERTED BY A REGISTERED INSTALLER, IN
ACCORDANCE WITH CURRENT REGULATIONS.
Before installation check data plate on rear of unit to ensure appliance is suitable for gas
supply available.
During installation provision must be provided for combustion air to the appliance through
base and rear of appliance. This should not be blocked at any time. This appliance should be
installed with adequate ventilation to prevent the occurrence of unacceptable
concentrations of substances harmful to health in the room in which it is installed.
POSITIONING
The appliance must not be installed on or against combustible surfaces –minimum
clearances must be: Rear 150mm (6”)
Sides 150mm (6”)
Hotplate to combustible material 1525mm (60”)
All local fire regulations should be observed. It is recommended that the appliance be sited
below a ventilating hood preferably of the extractor type incorporating a grease filter.
The cooker is manufactured with four castors two of which are braked. Caution should be
taken when manipulating or moving the unit. The appliance should be attached to a wall with
a chain to restrict the movement of the unit once connected to the gas supply. When the unit
is installed in position the brakes should be on.
Ensure the appliance is level, by placing a spirit level on the shelf in the oven, not on the pan
supports. All four castors are adjustable. To alter the height of the unit, loosen the locking
grub screw with an M3 allen key.
Next turn the large nut on the wheel assembly to either raise or lower the unit. When you are
happy with the height, tighten the locking grub screw with the M3 allen key.

Installation Instructions
The oven doors are held shut by adjustable roller catches. When installing the appliance
ensure the catches are set to allow the door to close firmly. To adjust the catch, use a
screwdriver to press in roller to below the plate, turn clockwise to adjust downward, and
anti-clockwise to lift the roller.
GAS CONNECTION
The size of the supply pipe should be no less than 3/4” B.S.P. and an easily accessible
isolation tap fitted close to the appliance in the gas line. Although a rigid connection is
recommended. An approved armoured flexible pipe may be used in conjunction with a
straining cable.
Before the appliance is commissioned the gas, safety regulations require that all
connections on the gas line are tested for gas soundness between the gas meter and the
appliance.
All packing and protective film must be removed from panels etc. prior to commissioning
the appliance. All gas appliances must be fitted by a competent person to gas safety
regulations in force.
Gas hoses used to connect the appliance to the gas supply must be of the correct
specification for the gas and pressure of the appliance. The gas hose must comply with the
national requirements in force, and be CE marked, of a metal braided construction suitable
for commercial catering equipment.
The hoses should be periodically examined and replaced as necessary. The tube or hose
shall be fitted such that there are no sharp bends or torsional strain which may cause
damage or failure of the tube or hose, especially near the end fittings. Torsional strain can
be prevented by using internal unions, swivel joints, etc. The bend radius should not exceed
that stated by the Manufacturer. The hose should not touch the ground and should be no
longer than 1.5m long.
A manual valve should be positioned upstream of the tube or hose unless the connection
fitting incorporates a self-sealing quick release coupling.

Installation Instructions
Where a quick release coupling is used for horizontal travel such as in commercial catering
appliances it is advisable that the coupling is facing downwards to prevent the ingress of
debris and ensure the hose is formed in to, a smooth curve. All units should have a
restraining cable fitted preventing the unit from being pulled away from the wall and
causing the gas hose to become disconnected accidentally.
Operating Instructions
Operating the hob
All burners are fitted with flame failure devices.
To light hob unit turn knob to
Press in and ignite gas with a match, keep knob held in for 15-20 seconds.
Release knob, gas should stay lit, if gas goes out then repeat stage 2.
The burner is now on full gas, to turn gas down, turn knob anti-clockwise, this is the
lowest setting, which is factory set.
To turn burners off, turn knob clockwise all the way round.
Parry recommends that the hob is used only with pans that have a minimum diameter of
120mm, and up to a maximum of 295mm diameter. This ensures that there is satisfactory
combustion, and the pan is stable as it sits on the finger of the pan support.
