▶ Make connections between the boiler and the pre-plumbing manifold
and the pre-plumbing manifold and the system pipes.
▶ Connect the CH flow pipes to the boiler's 22mm compression
connections.
▶ Connect the CH return pipes to the boiler's 22mm compression
connections.
▶ Connect the gas supply to the boiler gas cock 22mm compression.
▶ Connect cold water in and DHW out to the boiler's 15mm
compression connectors.
▶ Connect the PRV discharge pipe to the heating pressure relief valve,
ensuring that it is tightened securely.
▶ Connect the condensate discharge pipe work to the boiler's
condensate outlet connections.

Fitting the condensate pipework
▶ Secure the pipe to the wall at the last joint.
▶ Ensure the pipe protrudes through the pre-plumbing manifold by
25mm.
▶ If exiting through the wall, to run externally, the pipe must have a 3°
fall and be increased to a 32mm insulated pipe.

Condensate connection
Never terminate or discharge into any open source, including; sink,
bath, shower, bidet, toilet etc.
Any external condensate pipe work of an excessive run should be
protected with weather resistant insulation to help prevent freezing
( chapter 4.5).
▶ Ensure that the condensate drain is 22mm diameter plastic pipe. It
must fall at least 52mm per metre towards the outlet.
Refer to Fig. 51, condensate connection:
▶ Align the installation side plastic pipe work through the pre-plumbing
manifold.
▶ Connect the installation side plastic pipe work to the end of the
condensate hose.
▶ Push the plastic pipe work inside the condensate hose at least
25mm.
