7.0Site Requirement

7.3Ventilation of Compartments

1.Where the appliance is installed in a cupboard or compartment, no air vents are required.

2.BS 5440: Part 2 refers to room sealed appliances installed in compartments. The appliance will run sufficiently cool without ventilation.

7.4Gas Supply

1.The gas installation should be in accordance with the relevant standards. In GB this is BS 6891. In IE this is the current edition of I.S. 813 “Domestic Gas Installations”.

2.The connection to the appliance is a 22mm copper tail located at the rear of the gas service cock (Fig. 10).

3.Ensure that the pipework from the meter to the appliance is of adequate size. Do not use pipes of a smaller diameter than the boiler gas connection (22mm).

7.5Electrical Supply

1.External wiring must be correctly earthed, polarised and in accordance with relevant regulations/rules. In GB this is the current I.E.E. Wiring Regulations. In IE reference should be made to the current edition of ETCI rules.

2.The mains supply is 230V ~ 50Hz fused at 3A.

NOTE: The method of connection to the electricity supply must facilitate complete electrical isolation of the appliance.

Connection may be via a fused double-pole isolator with a contact separation of at least 3mm in all poles and servicing the boiler and system controls only.

7.6Bath & Shower Rooms

1.As the boiler is fitted with an integral timer when installed in a room containing a bath or shower it cannot be fitted in zones 1 or 2. (Figs. 11 & 12 shows zone dimensions for a bathtub. For other examples refer to Section 601 of the Current I.E.E. Wiring Regulations). Reference must be made to the relevant requirements. In GB this is the current I.E.E. Wiring Regulations and Building Regulations.

In IE reference should be made to the current edition of I.S.

813“Domestic Gas Installations” and the current ETCI rules.
