INSTALLATION INSTRUCTIONS
Before commencing installation of the appliance, please take time to read the following
installation instructions carefully.
Unit: SL6 and SL9 OVEN RANGE
All appliances should be installed in accordance with BS 6173:2001, Code of practice for installation of gas
catering appliances, taking into account the Gas Safety Regulations 1984 as amended by the Gas Safety
(Installation and Use)(Amendment) Regulations 1998 and the Health and Safety at Work Act 1974.
It is mandatory that all appliances are installed and commissioned by a qualified and competent CORGI
registered gas fitter.
Parts protected by the manufacturer are not to be adjusted by the installer.
WARNING: Installation, service or repair of this appliance by non-CORGI, registered personnel will
invalidate the warranty of the appliance.
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 450mm
2
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.
INSTALLATION POSITION.
A clear space of at least 50mm should be left at the rear of the unit between the appliance flue and the wall.
Consideration must also be given for pressure governor clearance when fitting to the appliance.
There should be a minimum clearance of 750mm between the top of the appliance and any overlying shelf or
ceiling.
To the side of the appliance, or bank of appliances a gap of at least 150mm should be allowed between it and
any adjacent wall panel or partition. Where it is impractical to provide such a gap, the adjacent wall or
partition should be clad with a non-combustible material.
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 safely operate, light and shutdown the appliance.
Although all Lincat oven ranges are operationally checked during manufacture, commissioning should
include an operational check of all controls.
Ensure that the appliance is level.
Before use, remove all protective plastic coating from the appliance.

INSTALLATION INSTRUCTIONS (Continued)
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.
Check that the gas supply pipeline has sufficient volume for the appliances/s to be connected to it.
WARNING: Black domestic hoses are not suitable for this appliance.
When making the connection onto 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 appliance for servicing
purposes.
PRESSURE SETTING
For Natural gas appliance only, fit the pressure governor supplied onto the inlet pipe-work after the isolating
cock. Remove the control panel and fit the pressure gauge to the test nipple situated on the left hand end of
the manifold. With the oven burner lit only and burning at full rate, adjust the burner pressure to:
17.5mbar for Natural gas
The supply pressure for Natural gas appliances are 20mbar and for LPG (Propane) appliances, 37mbar and
for Butane 30mbar nominal.
OVEN LOW FLAME SETTING
Check the low flame setting by lighting the oven and heating to a set temperature. When the set temperature
has been reached the thermostat will reduce the oven burner flame to its low rate. Check that rapid closing of
the oven door does not extinguish the flame. If necessary, adjustment to the low flame setting is made by
removing the oven knob and turning the bypass adjustment screw (Clockwise to decrease and anti-clockwise
to increase the flame). Care should be taken, as the appliance will become hot during commissioning.
Note: To obtain the above burner pressures adjust the regulator as supplied with the unit. When the correct
operating pressure has been obtained then re-assemble unit.
WARNING: Failure to check and set the oven low flame setting may initiate an un-necessary service
call due to the oven burner "going out".
HEAT INPUT.
The total nominal gross heat input for the appliances are as follows: -
Model SLR6
Butane gas 17.2 kW
Natural gas 20.1 kW
Propane gas 17.2 kW
Model SLR9
Butane gas 25.8 kW
Natural gas 30.3 kW
Propane gas 25.8 kW

OPERATING INSTRUCTIONS
LIGHTING of the APPLIANCE
Ensure the hob burner caps are in the correct position before lighting.
To light the hob burners, depress the relevant knob and rotate anti-clockwise through to the MAX position
(indicated by a large stylised flame). Manually light the burner using a match or taper keeping the knob
depressed for 20 seconds and then release. The burner should remain lit.
Adjusting the knob between the MIN and MAX position (small and large flame) will vary the heat input.
To light the oven, depress and rotate the oven knob anti-clockwise to the ignition position  and hold in this
position whilst operating the Piezo igniter. The oven burner should light. Keep the knob depressed for a
further 20-30 seconds after the burner is lit and then release. The burner should remain lit.
After selecting the desired cooking temperature, allow approximately 15 - 20 minutes for the appliance to
reach the desired set point.
At the minimum temperature setting the thermostat has a stop position on the valve. This stop position can be
used to place the appliance in a stand by mode.
The temperature graduations on the thermostat control knob are there as a guide to the temperatures at the
centre of the oven. The upper sections of the oven will be slightly hotter and the lower sections will be
slightly cooler than at the centre. Therefore, consideration must be given to the types of food stuffs being
cooked. As with ovens of this type it may be necessary to rotate the product during the cooking cycle. If
serving food from the oven then the product should be temperature probed for compliance with regulations.
WARNING: The outer panels of the appliance will get hot during normal operation and use. Care should be
taken when working next to these hot surfaces.
SHUT DOWN of the APPLIANCE
To turn off the appliance, depress and rotate the knob/s clockwise to the off position. Burner/s will now be
extinguished. Note: For the oven burner the control knob has a stop at the minimum temperature setting,
depress the knob fully home whilst rotating to the "OFF" position.
WARNING: After operation, the appliance will remain hot for some time. Care should be taken to avoid
injury.
PREPARATION for USE
Ensure the hob burner caps and the pan supports are in the correct position.
Check that the base tray has been correctly fitted.
MAINTENANCE of the OVEN RANGE
Pan supports can easily be removed from the unit for cleaning.
Clean burner caps regularly and ensure that the ports are free of debris.
The enamel base tray and shelves can be removed from the oven for cleaning.
Standard domestic de-greasing detergents are suitable for the cleaning of the oven liners.
For heavy, stubborn, deposits a de-greasing agent ‘CARBON-OFF’ is available from Lincat upon request.
