Installation Requirements

1.3

Gas Supply

The meter and supply pipes must be capable of delivering this quantity of gas in addition to the demand from any other
appliances in the house and must be governed at the meter.

The complete installation must be tested for gas soundness and purged as described in BS6891.

1.4

Electricity Supply

230V ~ 50Hz via a fused double pole switch with a contact separation of at least 3 mm in both poles adjacent to the boiler.
Power consumption is approximately 150W (inc. pump). There must be only one common isolator for the boiler and its control
system and it must provide complete electrical isolation.

Fuse the supply at 3 A. The minimum requirement for the power supply cable is that it should be a PVC sheathed cord at
least 0.75 mm² (24 x 0.2 mm) (code designation HO5 VV-F or HO5 VVH2-F) as specified in table 16 of BS6500:1984.

All wiring external to the boiler shall comply with the latest IEE Wiring Regulations, and any local regulations which apply.

WARNING: THIS APPLIANCE MUST BE EARTHED.

In the event of an electrical fault after installation of the boiler, preliminary electrical systems checks must be carried out i.e.
Earth Continuity, Short Circuit, Polarity and Resistance to Earth.

1.5

Location of Boiler

The boiler is not suitable for external installation unless it is suitably protected.

If the sealed system kit is being used, this should be installed first. See instructions supplied with kit.

The boiler must be installed so that the flue terminal is exposed to the external air. It is important that the position of the terminal
allows the free passage of air across it at all times.

The boiler must be mounted on a flat wall which is sufficiently robust to take the weight of the boiler.

The boiler is suitable for installation to a combustible wall e.g. wood cladding, provided that the flue duct is not closer than
25 mm to combustible material. A metal sleeve should be installed to surround the flue duct to provide a 25 mm annular space.
Further guidance is given in BS5440:1:2000, sub-clause 4.4.

If the boiler is to be installed in a timber framed building it should be fitted in accordance with the Institute of Gas Engineers
document IGE/UP/7/1998 (also, British Gas Service publication Part 19 - Building and Kitchen Work). If in doubt advice must
be sought from Potterton.

The boiler may be installed in any room, although particular attention is drawn to the requirements of the current IEE Wiring
Regulations and, in Scotland, the electrical provisions of the Building Standards applicable in Scotland with respect to the
installation of the boiler in a room containing a bath or shower. Where a room-sealed appliance is installed in a room containing
a bath or shower, any electrical switch or appliance control, utilising mains electricity should be so situated that it cannot be
touched by a person using the bath or shower.

Where the installation of the boiler will be in an unusual position, special procedures may be necessary and BS6798 and
BS5546 give detailed guidance on this aspect.

A cupboard or compartment used to enclose the boiler must be designed and constructed specifically for this purpose.
An existing cupboard or compartment may be used provided that it is modified for the purpose. Details of essential features
of cupboard/compartment design including airing cupboard installations are given in BS6798 and BS5546 and should be
complied with.

The boiler requires only the clearances shown on Page 6, after installation.
