Water Regulations and Byelaws
These regulations and byelaws ensure a good supply of wholesome water, and that only approved
materials, pipes and fi ttings 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 classifi ed as a "Controlled Service"
and Regulation G3 applies. To meet the requirements of the regulation, installation of an unvented sys-
tem 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 notifi ed 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 off ence 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-fi tted T&P)
Pressure relief valve set at 6 bar
Dielectric junctions

Important note: Dielectric junctions must be fi tted to all models as they prevent an electrolytic reac-
tion and safeguard against potential aggressive corrosion.

INSTALLING NORMS (for the installer)
Before installing the heater read these instructions in full.
If you are unsure please contact our technical service department (03332407777).
The installation must comply with all relevant Water Regulations/Byelaws and Building Regulations.
The installer should check with the local water authority for confi rmation of the maximum water
supply pressure.
The appliance should be left packed until it is ready to be installed. When unpacking take care not to
damage the 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 reducing valve must be installed). Please note that turning down the stop-cock will reduce
fl ow not pressure.
The outlet pressure from the reducing valve (if supplied) is 3.5 bar.
