5.1 Water Connections
The Flow and Return pipework can
be routed to either side of the boiler,
dependant on the type and direction of
the flue system used.
For condensate disposal pipework refer
to Section 6.
A drain cock is fitted at the bottom on
the front of the boiler to allow the heating
system to be drained, on the Boiler
House models the drain cock is supplied
in the accessories pack and requires to
be fitted.
All pipes to be fitted into the push-fit
connectors provided should be cut
using a pipe slicer or pipe cutter - to
leave the pipe ends with a slight
radius and free from any burrs or
sharp edges. Pipes to be used with
these fittings should not be cut square
using a hacksaw.
Pipe entry/exit holes in case
All Kitchen/Utility models except the
46/58 and 58/70 have holes to enable
the pipework to exit the boiler casing.
On the 15/21 and 15/26 models these
holes are pre-cut knock-outs located at
the rear of both side panels and on the
26/36 and 36/46 models these pre-cut
holes are in the removable flue outlet
cover plates.
Push out the 'knock-out' from the
required holes, taking care not to distort
the side panel.
On the 46/58 and 58/70 models the flue
outlet cover plates can be repositioned
to provide a vertical ‘letterbox’ pipe
opening, on either side of the boiler as
required. To do this, first remove both
casing top panels. Slacken the nuts on
the four fixing studs on the side cover
plate to be moved. Slide the plate
forwards by approximately 50 mm and
re-tighten nuts.

5.2 Water Connections -
System Models
A 15 mm discharge pipe must be connected
to the safety valve outlet connection. This
pipe must be unrestricted, i.e. no valves.
The discharge pipe should be run to the
outside of the building and terminate so
that it cannot cause injury to persons or
property.
A 15 mm double check valve ballofix
type valve is provided on the flexible
filling loop hose for connection of the
cold mains supply to the heating system.
The cold mains supply should terminate
inside the boiler casing.
The expansion vessel is connected via a
flexible hose to allow it to be moved to
gain access to the baffle cleaning cover.
When replacing the vessel, care should
be taken to ensure that the flexible
connecting hose is not twisted.
