Domestic Gas Installations

Avoid installing the boiler where the air inlet can be polluted by chemical products such as chlorine (swimming pool area), or ammonia (hair dresser), or alkalin products (launderette).

Flue

Detailed information on flue assembly can be found in the “Connecting the Flue” section.

The boiler must be installed so that the flue terminal is exposed to the free passage of external air at all times and must not be installed in a place likely to cause nuisance. It must not be allowed to discharge into another room or space such as an outhouse or closed lean-to.

Condensing boilers have a tendency to form a plume of water vapour from the flue terminal due to the low temperature of the flue gasses. The terminal should therefore be located with due regard for the damage or discolouration that may occur to building within the vicinity and consideration must also be given to adjacent boundaries, openable windows the min acceptable clearances are shown opposite.

NOTE: THE FLUE MUST NOT BE INSTALLED IN A PLACE LIKELY TO CAUSE A NUISANCE AND POSITIONED TO ENSURE THAT PRODUCTS OF COMBUSTION DO NOT DISCHARGE ACROSS A BOUNDARY

It may be necessary to protect the terminal with a guard, if this is the case it will be necessary to purchase a stainless steel terminal guard. Reference should be made to the Building Regulations for guidance.

Ventilation

The room in which the boiler is installed does not require specific ventilation. If the boiler is installed in a cupboard or compartment ventilation is not required for cooling purposes.

Gas Supply

The gas installation and tightness testing must be in accordance with the requirements of BS6891. Ensure that the pipe size is adequate for demand including other gas appliances on the same supply.

Electrical Supply

The appliance requires an earthed 230V - 50 Hz supply and must be in accordance with current I.E.E. regulations.

It must also be possible to be able to completely isolate the appliance electrically.

Connection should be via a 3 amp double pole fused isolating switch with contact separation of at least 3mm on both poles.

Alternatively, a fused 3 amp, 3 pin plug and unswitched socket may be used, provided it is not used in a room containing a bath or shower, it. It should only supply the appliance.

Water Supply

The boiler is suitable for sealed systems only. The maximum working pressure for the appliance is 6 bar. All fittings and pipework for the appliance should be of the same standard. If there is a possibility of the incoming mains pressure exceeding 6 bar, particularly at night, then a suitable pressure limiting valve must be fitted.

The boiler is designed to provide hot water on demand to multiple outlets within the property. If there is a requirement for greater demands, for example if the boiler has several bathrooms and cloakrooms, a vented or unvented hot water storage system may be used.

Showers

Any shower valves used with the appliance should be of a thermostatic or pressure balanced type.

Refer to the shower manufacturer for performance guidance and suitability.
