Alpha 500E - General Boiler Information
The flue terminal must be exposed to the external air and the position must allow the free passage of air across it at all times.
In certain weather conditions the terminal may emit a plume of steam. Avoid positioning the terminal where this may cause a nuisance.
If the terminal is fitted within 850 mm of a plastic or painted gutter or 450 mm of painted eaves, an aluminium shield at least 1 m
long should be fitted to the underside of the gutter or painted surface. If the terminal is fitted less than 2 m above a surface to
which people have access, the terminal must be protected by a terminal guard.
A suitable guard (type K3 - G.C. No. 393 554) is available from:
Alpha Therm Ltd., Goldsel Road, Swanley, Kent BR8 8EX, or Tower Flue Components Ltd., Vale Rise, Tonbridge, Kent TN9 1TB

BOILER LOCATION
The boiler is not suitable for external installation.
The boiler must be installed on a flat vertical wall which is capable of supporting the weight of the boiler, i.e. 130 kg.
If the boiler is to be fitted in a timber framed building, it should be fitted in accordance with the British Gas publication 'Guide for
Gas Installations in Timber Frame Housing', reference DM2.
The boiler may be installed in any room or internal space, although particular attention is drawn to the requirements of the current IEE Wiring
Regulations, and in Scotland, the electrical provisions of the Building Regulations applicable in Scotland, with respect to the installation of
the boiler in a room or internal space containing a bath or shower. Where a room-sealed boiler is installed in a room containing a bath or
shower, it must not be possible for a person using the bath or shower to touch any electrical switch or boiler control utilising mains electricity.
The boiler may be installed in a cupboard or compartment, provided it is correctly designed and sufficiently ventilated for that
purpose and that the requirements of BS 6798 and BS 5440:2 are complied with.
