SITING
The installer must ensure that all regulations are met and that there is an
unobstructed minimum distance of 750mm from the top of the flue to the ceiling,
which must be of non-combustible material.
The appliance should be installed on a level surface ensuring the unit is stable and firmly
located.
Any partitions, walls or kitchen furniture in close proximity must be of non-combustible
materials and not be closer than 50mm from the sides and rear of the flue.
These appliances are to be installed with sufficient ventilation to prevent the occurrence of
unacceptable concentrations of substances harmful to health in the room in which they are
installed.
GAS SUPPLY AND CONNECTION
The gas inlet connection is at the rear of the appliance. The pipe work should be of
adequate size but not smaller than the gas inlet connection at the rear of the appliance,
i.e. Rp 1/2” BSP.
The gas supply tubing or hose shall comply with national requirements in force and shall
be periodically inspected and replaced as necessary.
WARNING: Black domestic hoses are not suitable for this appliance.
All joints made must be leak free.
Final gas connection to the appliance and gas supply shall comply with local regulations.
SUPPLY PRESSURES
The appliance is supplied with a governor which must be fitted in the supply line to the unit
and adjusted accordingly. See Technical Data for the supply pressures.
To gain access to the gas pressure test nipple the facia panel requires removal (see
page 10). The test nipple is situated in the centre of the manifold rail.
Remove the blanking screw and attach a pressure gauge to the boss of the test
nipple.
With all the burners lit and set to maximum, ensure that the supply pressure for
Natural gas is 20mbar and the adjusted pressure is 16mbar. For Propane
appliances ensure the supply pressure is 37mbar and the adjusted pressure is
25mbar.
For those destination countries where the supply pressure exceeds the supply
pressures given in the Technical Data above a regulator must be fitted and the
supply pressure set to the pressures detailed.
Once connected to the gas supply, check for soundness and then purge the
appliance by rotating all control knobs to the ignition position and depressing them.
Hold the knobs depressed to purge the supply pipe and internal pipe work of air.
Periodically check for gas flow by depressing the igniter buttons.
Commissioning must include an operational check of all controls.
Ensure that the operator understands how to light, safely operate, clean and
shutdown the appliance and is aware of the position and operation of the gas
isolating cock.
