INSTALLATION INSTRUCTIONS
Before commencing installation of the appliance, please take time to read the installation instructions
carefully.
All appliances should be installed in accordance with BS 6173, Code of practice for installation of gas
catering appliances, taking into account the Gas Safety Regulations as amended by the Gas Safety
(Installation and Use)(Amendment) Regulations and the Health and Safety at Work Act.
It is mandatory that all appliances are installed and commissioned by a qualified and competent CORGI
registered gas fitter. WARNING: Installation, service or repair of this appliance by non-CORGI registered
personnel may invalidate its warranty.
1.1 VENTILATION
The area in which this equipment is to be installed should have sufficient fixed ventilation to comply with
the requirements of Approved Document J in the 2002 Building Regulations. It is recommended that a
minimum area of 450mm2 per 1kWh (3400Btu/hr) of total heat input must be allowed. Particular attention
should be paid to the low-level ventilation to ensure that the appliance has a good supply of clean, fresh
air.
1.2 INSTALLATION POSITION
The unit must be mounted on a work surface or stand, which must have either a metal or open top.
There should be a minimum clearance of 750mm between the top of the appliance and any overlying
shelf or ceiling.
Where the unit is to be free standing, any partitions, walls or kitchen furniture in close proximity (at least
50mm clearance given on all sides) must be of non-combustible materials.
1.3 INSTALLATION COMMISSIONING
To ensure a full understanding of the correct operation of the appliance the following commissioning
checks must be carried out before the appliance is handed over for use.
All operators must know how to light, safely operate and shutdown the appliance.
Although all Lincat griddles are functionally checked during manufacture, commissioning should include
an operational check of all controls.
Ensure that the unit is level.
Before use, remove all protective plastic coating from the unit.
1.4 GAS SUPPLY & CONNECTION
Check that the gas supply corresponds to that specified on the data plate.
Connection is via a 1/2" bspt male thread on the back of the unit. If connection to the supply pipe is via a
flexible hose, ensure that the hose used is suitable for commercial catering appliances. The hose should
be periodically examined and replaced as necessary.
WARNING: Black domestic hoses are not suitable for this appliance.
When making the connection on to the appliance, secure the hexagon on the fitting to prevent rotation of
the internal pipe work. An isolating cock should be fitted into the supply line to the unit for servicing
purposes.

1.5 PRESSURE SETTING
Pressure setting can be carried out by the removal of the facia panel. This procedure is to expose the test
nipple.
With all burners lit and set to maximum, ensure that the supply pressure for Natural gas appliances is
20mbar and the burner pressure is adjusted to 16mbar. For Propane appliances ensure the supply pressure
is set to 37mbar and the burner pressure is set to 25mbar.
Pressure measurement is via the test nipple at the end of the manifold rail. Note: To obtain the above
burner pressures adjust the regulator as supplied with unit. When correct operating pressures are
obtained, re-assemble the unit.
1.6 HEAT INPUT
The total nominal gross heat input for the appliances with both burners in full operation are as follows: -
GS4/N Natural gas 5.4 kW
GS4/P Propane gas 5.5 kW
GS7/N Natural gas 7.5 kW
GS7/P Propane gas 8.0 kW

OPERATING INSTRUCTIONS
2.1 LIGHTING the APPLIANCE
With the knob in the OFF position (), depress fully, and rotate anti-clockwise to the MAX position
(indicated by a large stylised flame) to allow gas to feed through to the burners.
To light the main burners, press the appropriate orange ignitor.
When the burners are lit, visible through sight holes in fascia, keep the knob depressed for a further 30
seconds to heat the thermocouple and then release the knob, the griddle will take approximately 20
minutes to achieve full working temperature from cold.
The heat input can be adjusted between MAX (large stylised flame) and MIN (small stylised flame) to
give the desired working temperature.
WARNING: - The outer panels of these units will get hot during operation; therefore, care should be
taken when working next to them.
2.2 SHUT DOWN OF APPLIANCE
When use of the appliance is no longer desired rotate knob clockwise to the OFF position, burners will
now be extinguished.
WARNING: - After use, some parts of the appliance will remain hot for a period of time.
Please take care to avoid accidental burns.
2.3 PREPARATION FOR USE
2.3.1 Clean the surface of the griddle with hot soapy water. Dry thoroughly and lightly coat in cooking
oil.
2.3.2 Ensure that the fat drawer is correctly positioned.
2.3.3 Light the unit as described above and allow 20 minutes to heat up to maximum temperature before
use. Adjusting between the MAX and MIN settings will control the cooking heat.
2.4 CARE OF GRIDDLE PLATES
2.4.1 Steel plate
After cooking, scrape off any food residue and wash down with a mild detergent and water.
Rinse to ensure that all traces of detergent have been removed. Once clean and dry, the plate can
be protected with a light coat of cooking oil.
For heavy, stubborn deposits a de-greasing agent such as, ‘CARBON-OFF’ is available from
Lincat upon request.
2.4.2 Chromed Plate
Food debris should be removed regularly during use.
After turning the griddle off, allow 15 minutes for the griddle plate to partially cool down and
flush with a small quantity of water to soften any residue and further cool the plate.
Use a stiff bristle brush to loosen food residue and scrape it into the fat drawer.
Repeat the flushing process, adding a small amount of mild detergent to the water and again empty
into the fat drawer, taking care that it doesn’t overflow.
Wipe the plate with a soft cloth.
Do not use sharp cornered instruments on a chromed griddle surface.

SERVICING
Gas catering equipment should be routinely serviced to ensure a long trouble-free life. With this in mind, it is
recommended that a competent gas engineer service the appliances every 6 months.
Please see page 12 “Service” for information on authorised service agents.
3.1 GENERAL SERVICE
General check of the equipment, e.g. installation - is the unit on the correct hose? Does the hose have
a safety chain? Does the equipment have a separate isolation valve?
To access the valve/s, pull off the knobs and remove screws from the facia panel.
Lower the fascia panel to reveal the valves.
Check and adjust where necessary the burner pressure at the test nipple, with the unit in full
operation.
Check the general burner condition.
Check the thermocouple/s for sooting etc. and clean. Check for correct operating distance (3mm
from the centre of the thermocouple to the burner face).
Carryout a gas soundness check.
Refit the fascia panel and the control knob/s.
