7 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 If an optional Pump Kit is to be used then it must be
fitted at this stage. Refer to separate fitting
instructions included with the kit.
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.
It is IMPERATIVE that the INDEX MARK on the
distributor 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 5 and 6.
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 when fitted.
5. Place the boiler in position. Note . The pump may be
fitted on the FLOW or RETURN.
