Fitting The Boiler
(Fig. 24)
1. Obtain retaining bracket and two M6 nuts from fitting
bag.
2. Offer up the boiler to the wall plate using the lifting
points shown in Fig. 24 and locate the rear bottom edge
onto the self locating support at the base of the wall plate.
(See
Safe Manual Handling
page 5.)
NOTE: When installing in a Loft/Small Compartment,
access for lifting the boiler from the front can be
gained for two people using the lifting points. (Fig. 24).
3. Rotate the boiler up to wall plate and engage retaining
bracket, securing with the two nuts.
4. Ensure the boiler is secured with the retaining
bracket.
5. Remove red pipe protection caps from the FLOW and
RETURN connections.

Making the Water Connections
(Fig. 25)
1. The boiler has two side water connections which are
labelled FLOW and RETURN. The front connection is the
flow pipe and the rear threaded connection is the return.
2. It is essential that the flow and return pipes are
connected to the boiler correctly. The flow connection
incorporates the boiler thermostats and a flow switch.
3. The boiler connections will accept 22mm fittings.
NOTE: On 30 models 28mm pipe should be used to
connect to the boiler flow and return using suitable
reducing fittings.
4. If the installation requires that the system pipework
originates from the bottom of the boiler, then the flow
and return pipes will need cutting, as they terminate
upwards.

Making the Condensate Drain Connection
1. Connect the condensate drain using the 1”BSP nut and
seal supplied. (see section 7.6).
NOTE: To ensure the correct operation and
integrity of the condensate drainage system -
Carefully pour approximately 1 cupful (250ml) of
water into the flue products exhaust, at the top of the
heat exchanger (Fig. 25a) to ensure a seal is made in
the trap.
