Installation requirements
Location
The boiler can be installed on any suitable internal wall.
Provision must be made to allow the correct routing of the flue
and siting of the terminal to allow the safe and efficient
removal of the flue products. A compartment or cupboard may
be used provided that it has been purpose-built or modified for
the purpose. It is not necessary to provide permanent
ventilation for cooling purposes. Detailed recommendations
are given in BS 5440 pt 2. If it is proposed that it is installed in
a timber framed building then reference must be made to
British Gas Document DM2, or advice sought from CORGI.
Flue
Detailed information on flue assembly is contained in the
appropriate starter pack.

exposed to the free passage of external air at all times. It must
not be allowed to discharge into another room or space such
as an outhouse or closed lean-to. The minimum acceptable

Ventilation
The room in which the boiler is installed does not require specific
ventilation.
If it is installed in a cupboard or compartment
permanent ventilation is not required for cooling purposes.
Gas Supply
The gas installation and soundness testing must be in
accordance with the requirements of BS 6891.The boiler
requires a 22 mm supply. Ensure that the pipe size is
adequate for demand including other gas appliances on the
same supply.
Electrical Supply
The appliance requires an earthed 230V - 50 Hz supply and
must be in accordance with current I.E.E. It must also be
possible to be able to completely isolate the appliance
electrically. Connection should be via a 3 amp fused double-
pole isolating switch with contact separation of at least 3 mm
on both poles. Alternatively, a fused 3 Amp. 3 pin plug and
unswitched socket may be used, provided it is not used in a
room containing a bath or shower. It should only supply the
appliance.
