5.19 Water Connections
1. The boiler has two side water connections, the top
connection being FLOW and the bottom connection being
RETURN (Fig. 75).
2. It is essential that FLOW and RETURN pipes are
connected to the correct fittings.
3. The top flow connection incorporates the boiler
thermostat, overheat thermostat arid a venting point (Fig.
76).
4. A copper elbow, compression nut and olive are
provided in the kit for the return connection.
NOTE: Drain cocks should be fitted to all the
system's low points.
5. Connect the two electrical tags of the thermostat lead
to the connections on the thermostat - either wire can be
connected onto either connection -there is no polarity
(Fig. 76).
6. Remove the overheat thermostat and clip from the
plastic kit bag. Engage the thermostat in the clip as
shown (Fig 76). Prise the clip over the flow pipe as near
to the vent as possible (Fig. 76 & 77).
7. Connect the two electrical tags from the wiring
harness to the terminals on the overheat thermostat
(Fig.77) - either wire can be connected onto either
terminal - there is no polarity.
5.20 Pipe Routes
1. 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.
2. Pipes may be dropped down within the outer case in
the spaces between the back plate and the combustion
box
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 back plate.
5.21 Gas Connection
1. Connection to the gas supply is R ½ ( ½ in BSPT
internal) located at the rear of the gas cock-(Fig. 78).
2. When connecting the gas feed pipe, the control box
may be pulled forward to give greater access.
