When suitable installation clearances are available, position
the boiler in readiness to connect pipework.
If suitable clearances are not available it will be necessary to
preplumb the gas and water connections before positioning the
boiler.
When the front connections are used it is essential that any
pipework or fittings be assembled as shown in diagram 4.5, that
is, do not stick out more than shown.
Make the water connections to the system pipework.
Make the gas connection to gas supply at the union gas service
cock. Test the complete gas installation for soundness and
purge in accordance with the current issue of BS6891.
4.6 Pump within Boiler Casing
If the pump is to be fitted inside the boiler casing connect it as
shown to either of the upper front flow connections, see diagram
4.6.
There must be sufficient clearance “X” between the pump body
and the flueway cleaning door to allow removal of the door.
Dependent upon the type of pump used, the flow pipe
arrangements and pump may require titling backwards to clear
the casing door.
4.7 Flue Connection
The flue should be 125mm (5in) nominal diameter, refer to
Section 3 and diagram 1.1.
