11 PREPARING THE BOILER
Note.
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.
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 7.
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.
