The pipework connections are housed within an
insulated compartment inside the rear end of the
boiler casing (opposite end from the burner). These
connections are accessed by removing the back panel
of the enclosure.

The boiler side panels are fitted with movable plates
to allow the pipework to exit the boiler enclosure. The
side flue exit holes in the side panels may also be
used to route the pipework and cables into the
building. Where the boiler is sited remotely from the
building, the pipework can be routed through the
holes in the base of the rear compartment.

Fit the double check valve to the mains water supply,
ensuring correct flow direction as indicated by the
arrow on the valve. Fit the pressure gauge and shut-
