Alpha Pro Tec - General Boiler Information
3.5 FLUE TERMINATION
The Alpha ProTec range of boilers can be individually ued using either 80 mm open ue conguration or 80/125 mm
concentric ue.
Multiple boilers can be individually ued or cascade ue kits are also available.
When installing these boilers careful planning and consideration for the ue system must be undertaken. All ue systems
must conform to the relevant standards depending on the boiler size and conguration.
Refer to BS 6644, BS 5440 or IGE/UP/10 for the correct ue location requirements.
3.6 BOILER LOCATION
The boiler is not suitable for external installation unless it is installed within a purpose designed weatherproof building.
The boiler must be installed on a at vertical wall which is capable of supporting the weight of the boiler. The boiler can be tted
to or adjacent to a wall comprising of a combustible material without the need for a special thermal insulation barrier.
If the boiler is to be tted in a timber framed building, it should be tted in accordance with the Institute of Gas Engineers
'Guide for Gas Installations in Timber Frame Housing', reference IGE/UP/7.
The boiler may be installed in any room or internal space, although particular attention is drawn to the requirements of the
current IEE Wiring (BS 7671) 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 for that purpose, i.e. complies
with the Building Regulations and the requirements of BS 6798 and BS 6644.
Propane Gas (LPG): Installation pipes, cylinders and pressure regulators should be tted in accordance with BS 5482:1.
Bulk tank installation must comply with the requirements of the Home Ofce code of practice for the storage of liqueed
petroleum gas at xed installations. The boiler must not be installed in a room or internal space below ground level, e.g. in a
basement or cellar, except where at least one side is open to ground level.
3.7 FROST PROTECTION
The boiler is tted with a frost thermostat that activates the pump and burner when the system water temperature in the
boiler falls below 3°C.
The electrical supply to the boiler must be left on for the thermostat to operate and the selector switch must be set to ON .
