Fig. 24 8.3 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 and locate the rear
bottom edge onto the self locating support at the base
of the wall plate.
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 14
mm 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 7.8.).
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.
