INSTALLATION
SITING
The installer must ensure that all regulations are met and that there is an unobstructed
minimum distance of 1000mm 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.
The LM9D has adjustable feet which must be set to level the appliance.
GAS SUPPLY AND CONNECTION
Connection is at the rear of the unit via a 1/2" G male thread.
Connection shall comply with local regulations, and the hose should be periodically
examined and replaced as necessary.
When making the connection to the appliance an isolating cock should be fitted into the
supply line close to the unit, for emergency shutdown or servicing purposes.
BURNER PRESSURE ADJUSTMENT
Applicable only to those countries having a standard supply pressure of 50mbar for Butane or Propane gas.
To gain access to the gas pressure test nipple open both oven doors (Lower if LMD9).
The nipple is situated beneath the control panel on the left of centre.
Remove the blanking screw and attach a pressure gauge to the boss of the test
nipple.
Light an oven burner with thermostat set to maximum.
Adjust the pressure at the governor. See table above.
For appliances operating on Butane gas there may be some ‘yellowing’ of the flame at
the burner –this is nomal owning to the composition of the gas.
LOCKING OF WHEELS (LMO9 only)
When the appliance has been installed in its intended position the front casters should be
locked by depressing the locking tabs on the castors.
Locks should only be released for the intention of moving the appliance for
cleaning purposes and or routine servicing of the appliance.
