1.3 VENTILATION
Adequate ventilation must be provided to supply sufficient
fresh air for combustion and allow easy removal of
combustion products which may be harmful to health.
Recommendations for Ventilation of Catering Appliances
are given in BS5440:2.
For multiple installations the requirements for individual
appliances should be added together. Installation should
be made in accordance with local and/or national
regulations applying at the time. A competent installer
MUST be employed.
1.4 GAS SUPPLY
The incoming service must be of sufficient size to supply
full rate without excessive pressure drop.
A gas meter is connected to the service pipe by gas
supplier. Any existing meter should be checked by
supplier to ensure it is of adequate capacity to pass
required rate for appliance in addition to any other gas
equipment installed.
Installation pipe work should be fitted in accordance with
IGE/UP/2. The pipe work should be of adequate size but
not smaller than unit gas inlet connection, i.e. Rp½
(½” B.S.P.). An isolating cock must be located close by to
allow shut-down during an emergency or servicing.
If flexible tube is used, the gas supply tubing or hose shall
comply with national requirements in force. These will be
periodically examined and replaced as necessary.
The installation must be tested for gas tightness.
Procedure details can be found in IGE/UP/1.
The adjustable governor supplied must be fitted to
natural gas appliances.
1.5 ELECTRICAL SUPPLY
Not applicable to this appliance.
1.6 WATER SUPPLY
Not applicable to this appliance.
1.1 MODEL NUMBERS, NETT WEIGHTS
and DIMENSIONS
The grill may be mounted on one of the following options:
Bench legs, floor stand or wall bracket.
1.2 SITING
The appliance should be installed on a level, fireproof
surface, in a well lit and draught free position.
If the floor is constructed of combustible material, then
local fire requirements should be checked to ensure
compliance. A clear space of 150mm should be left
between rear and side of unit and any combustible wall.
Important
If a unit is to be installed in suite formation with other
matching appliances, the instructions for all models must
be consulted to determine the necessary clearances to
any combustible rear wall or overlying surface.
Some models require greater clearances than others and
the largest figure quoted in individual instructions will
therefore determine clearance for complete suite of
adjoining appliances.
Grills may be mounted on bench legs, a floor stand or a
wall bracket.
Grills must not be placed directly upon a table top.
The grill flue discharges vertically through the top of the
appliance, meaning the top of the appliance gets very hot.
There must be no direct connection of flue to any
mechanical extraction system or to the outside air.
Care should be taken not to disturb the air combustion
admission and evacuation of open top burner
Warning
Extraction filters and drip trays become combustible
without regular cleaning.
Grills under extraction canopies must have a flue diverter
fitted as advised in DW172.
Note
G3532 model is not compatible with old-style plate
shelves.

SECTION 3 -
SERVICING and CONVERSION
Important
BEFORE ATTEMPTING ANY SERVICING, ENSURE
ISOLATING COCK IS TURNED OFF AND CANNOT BE
INADVERTENTLY TURNED ON. AFTER ANY
MAINTENANCE TASK, CHECK APPLIANCE TO
ENSURE THAT IT PERFORMS CORRECTLY AND
CARRY OUT ANY NECESSARY ADJUSTMENTS AS
DETAILED IN SECTION 1.
After carrying out any servicing or exchange of gas
carrying component.
ALWAYS CHECK FOR GAS TIGHTNESS!
3.1 GAS CONVERSION CHECK LIST

from gas circuit.
Other considerations
CHANGE INJECTORS
SET LOW RATE
Refer to Section 1.9.

3.3 CLEANING
3.3.1 Burners
Burners should be cleaned periodically to maintain
maximum performance as detailed in User
Instructions. Burners are best cleaned with a wire brush;
port blockage should be freed using a metal broach, any
loose material being shaken out via burner shank.
Ensure burners are dry and free from any cleaning
material before replacing.
Check adjustment as detailed in Section 1.
3.3.2 Injectors
Injectors are best cleaned with a wooden splinter or soft
fuse wire. Metal reamers may distort or increase orifice
size and their use should be avoided.
3.4 THERMOCOUPLES and
FLAME FAILURE DEVICE (FFD)
3.4.1 Flame Failure Device Magnet Unit
To remove and replace FFD magnet unit, the following
procedures must be followed.
Remove hob components as detailed in Section 3.2.2.
Undo FFD thermocouple at rear of tap, undo FFD
section at tap rear and withdraw.
Replace in reverse order.
3.4.2 Thermocouple
Follow section 3.1.1 to instruction e)
Remove nut securing thermocouple to burner support
bracket. Pull thermocouple through bracket from
underside.
Undo thermocouple connection at FFD section of gas tap
and carefully remove thermocouple.
Replace in reverse order.
Ensure thermocouple does not touch any part of burner
when fully re-assembled.
3.5 GOVERNOR (Natural Gas Models Only)
The governor supplied is maintenance free. Check that
blue dust cap is covering vent and in good condition as
this protects the breather hole.
When checking for gas leaks around governor, be aware
that unburned gas may be vented occasionally to release
pressure on diaphragm. This should not be confused with
a gas leak.
3.6 GAS TAPS
Note
Plugs and bodies are machined in pairs and are
therefore not interchangeable. Always clean one tap at
a time.
3.6.1 Service
Remove control knobs and facia panel as detailed
in Section 3.2.1.
Remove fixings from front of tap body. Withdraw spindle
and niting arrangement to allow plug to be eased out.
Clean gas tap plug with a soft rag and regrease using an
approved high temperature lubricant. Take care not to
over-grease as surplus may cause gasway blockage.
Replace parts in correct order and check
gas tightness.
3.7 FAULT CHECK LIST
If a flame is not established on the burners follow this
check list.
1. Check mains gas is ON.
2. Check pressure at test point to ensure gas
is flowing to unit.
3. If pressure does not register then check governor
is fully operational or check for line blockage.
4. If gas is present, check burner injector for
blockage.
5. If injector is OK then check FFD is engaging and
passing gas.
6. If flame is still not present, then re-check from start.
If flame is established but not maintained, follow this
check list.
1. Check thermocouple is positioned correctly in burner
flame. Burner ports must be clean.
2. Check thermocouple is not damaged and is
secured to gas valve FFD section to allow FFD to
energise.
3. Check FFD is energising and maintaining flame.
4. If, after carrying out the above, burner is still not
maintaining flame then re-check from start.
SECTION 4 - SPARES
