Adjusting the baffle.
The baffle plate is supplied separately and should be fitted
into the heater as indicated in fig. 6.
Use the adjustment jig provided (fig. 5) to adjust the baffle
to the right size. Once it has been adjusted, fix the damper
in place with the socket-head screw.
See the table for adjustment specifications.
In some cases the air inlet baffle should be removed
(tabel).
To do this: (fig. 7).
Take strip (1) and the vermiculite trays (2+3) out of the
appliance.
Remove the air inlet baffles and screw the self-tapping
screws back in place.
Replace the vermiculite trays (2+3) and the strip (1) in the
appliance.
NB: the maximum length of horizontal pipe
must not be exceeded.
Fig. 4 illustrates how to calculate the total lengths of pipe.

Connecting the Gas Supply

An approved connecting tap with coupling should be used
in the supply hose (In Belgium this must be B.G.V.
approved). Furthermore:
• Expel all air from the supply pipes/hoses before coupling
to the appliance.
• Do not turn the coupling tap when connecting it to the
gas supply.
• Avoid any pressure on the control tap and pipes.
• Check that all connections are gastight.
