Fitting The Boiler
(Fig. 24)
1. Remove the screw and retaining bracket from the
wall plate spring clip.
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
Lifting
paragraph page 4).
NOTE: When installing in 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 and engage into temporary spring
retaining latch.
4. Ensure the boiler is secured with the retaining
bracket and screw previously removed,
immediately.
5. Remove thread protection caps from the FLOW and
RETURN connections.
8.4
Making the Water Connections
(Fig. 25)
1. The boiler has two side water connections, the front
connection being FLOW and the rear connection being
RETURN.
2. It is essential that Flow and Return pipes are
connected to the correct fittings. The flow connection
incorporates the boiler thermostats and a flow switch.
To avoid damage to the flow switch when tightening
the flow connection the use of two spanners is
recommended.
3. A copper elbow, compression nut and olive are
provided in the kit for the return connection.
NOTE:
Drain cocks should be fitted to all system’s
low points and vents to all high points.
4. Ensure that any pipework is routed so as to leave
the boiler via the spaces at the rear of the outer case,
either at the top or at the bottom.
Pipework within the
confines of the outercase should consist of solder
fittings.
NOTE:
It is important that the pipework does not
interfere with the correct fitting of the outer case and
a space of 14mm clearance must be left between any
vertical pipes and the outer edge of the wall plate.
8.5
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.
