the current building regulations should
be used. Installation should be carried
out generally as shown on the following
diagram.

2.1.3 Gas connection

The gas supply to this appliance must
be installed in accordance with BS
6891 (1988).

Fit the 1/2" gas supply cock supplied
with this unit immediately before the
gas control block. No heat or soldered
joints should be applied in the vicinity
of the gas control block, as they could
cause damage to the control.
All connections and joints should be
tested for gas soundness with a
suitable leak detector (do not use a
naked flame).

2.1.4 Flue-gas exhaust and air

supply

The flue-gas exhaust and the air
supply must be installed according to
the tables.
