PREPARING THE BOILER
Notes
.
z
Before placing the boiler in the selected position any
gas and water connections at the rear of the boiler
should be prepared, due to the possible lack of
access.
z
The pump may be fitted to the FLOW or the RETURN.
1.
Screw the distributor tube (supplied with a 1" BSP x
28mm copper adaptor) into the selected heating return
tapping, using an appropriate jointing material.
IMPORTANT.
It is
IMPERATIVE
that the index mark on the distributor tube
bush is in alignment with the mark on the section boss, as
shown in Frame 3.
DO NOT disturb it when connecting subsequent
pipework.
Fully pumped systems using more than 1 pump, serving
separate zones, must have a common return connection
to the distributor tube.
2.
Select the desired pumped flow tapping.
3.
Screw the supplied boiler thermostat pocket into the
appropriate front section tapping, using an approved
jointing material. Refer to Tables 7 and 8.
4.
Connect pipe fittings to the rear tappings and plug any
unused tappings.
Note

If using iron elbows fit a short straight connector into
the boiler tapping first, to clear the casing.
