Safety Instructions
IMPORTANT
PLEASE READ INSTRUCTIONS FULLY BEFORE USE
INSTALLATION INSTRUCTIONS
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.
INSTALLATION
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 sufficient 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.

Installation Instructions
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 the use of 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.
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
FOR FITTING INSTRUCTIONS SEE INSTALLATION SECTION.
Operating the hob
All burners are fitted with flame failure devices.
1. To light hob unit turn knob to
2. Press in and ignite gas with a match, keep knob held in for 15-20 seconds.
3. Release knob, gas should stay lit, if gas goes out repeat stage 2
4. The burner is now on full gas, to turn gas down, turn knob anti-clockwise, this is the
lowest setting, which is factory set.
5. 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.
We advise these appliances should not be left unattended while switched on.
These appliances are for professional use by qualified people only.
There are no user serviceable parts.
It is recommended that the sealed top plate is cleaned regularly to prevent build-up of fat
and grease.
Cleaning Instructions
It will be found that it takes less time and effort to clean the hob every time it has been
used, particularly whilst still warm before grease and spillages are burnt on. Proprietary
cleaners must be used with care –they are highly corrosive and may cause damage to
surfaces and components. The stainless outer panels require a wipe down with warm soapy
water.
DO NOT USE SCOURING PADS.
