Air supply

Detailed recommendations for air supply are given in
BS 5440: Part 2. It is not necessary to have an air vent
in the room or internal space in which the boiler is
installed.
3.5

Compartment ventilation

The boilers are very high efficiency appliances. As a
consequence the heat loss from the appliance casing
during operation is very low. Compartment ventilation is
required if the flue used is not concentric and air is
supplied from the room or compartment the boiler is
installed in.
3.6

Electrical supply

A 230 V, ~ 50 Hz single phase electricity supply fused to
3 Amp. must be provided in accordance with the latest
edition of BS7671 (IEE Wiring Regulations) and any other
local regulations that may apply. In IE reference should
be made to the current edition of the ETCI rules. The
method of connection to the mains electricity supply
must provide a means of completely isolating the boiler
and its ancillary controllers. Isolation is preferably by
the use of a fused three pin plug and unswitched
shuttered socket outlet, both complying with the
requirements of BS 1363. Alternatively, a 3 Amp. fused
doublepole switch with a 3 mm contact opening on both
poles may be used.

Danger!

Risk of fatal electric shock!
The boiler must be earthed.
