for the passage of pipes around local obstructions such
as joists running parallel to the front face of the boiler.
7.4 Location
1. The boiler may be fitted to any suitable wall with the
flue passing through an outside wall or roof and
discharging to atmosphere in a position permitting
satisfactory removal of combustion products and
providing an adequate air supply. The boiler should be
fitted within the building unless otherwise protected by
a suitable enclosure i.e. garage or outhouse. (The
boiler may be fitted inside a cupboard - see Section 7.5
).
2. If the boiler is sited in an unheated enclosure then it is
recommended to leave the ON/OFF Selector Switch in
the domestic hot water and central heating position to
give frost protection.
3. If the boiler is fitted in a room containing a bath or
shower reference must be made to the current I.E.E.

REGULATIONS. If the boiler is to be fitted into a
building of timber frame construction then reference
