Water Regulations and Byelaws

These regulations and byelaws ensure a good supply of wholesome water, and that only approved materials, pipes and

fittings are used to convey water.

Building Regulations

These are a statutory document and take priority over all other regulations and recommendations. The installation of an

unvented hot water system of over 15 litres is classified as a "Controlled Service" and Regulation G3 applies. To meet the

requirements of the regulation, installation of an unvented system should be undertaken by a "competent installer".

All installations of unvented hot water storage systems having a capacity of more than 15 litres should be notified to the

relevant Local Authority by means of building notice or by the submission of full plans. It is important to note that it is a

criminal offence to install an unvented hot water storage system over 15 litres without notifying the Local Authority.

Delivery

The products are supplied with the following:

Unvented water heater (with factory-fitted T&P)

Pressure relief valve set at 6 bar

Dielectric junctions

Tundish

Expansion Vessel

Check Valve

Pressure reducing Valve

Important note: Dielectric junctions must be fitted to all models as they prevent an electrolytic reaction and safe-

guard against potential aggressive corrosion.

If the supplied Dieletric Junctions are not fitted this could void the warranty.

INSTALLATION NORMS (for the installer)

Before installing the heater read these instructions in full. If you are unsure please contact our technical service

temperature and pressure relief valve on the top of the heater.

A drain has to be provided for any water discharged through the safety valves.

A cold water supply pressure between 1 and 3.5 bar is required (if the mains pressure is above 3.5 bar a pressure reduc-

ing valve must be installed). Please note that turning down the stop-cock will reduce flow not pressure.

The outlet pressure from the reducing valve (if supplied) is 3.5 bar.
