The technical information and instructions provided herein below are intended for
the installer so that the unit may be installed correctly and safely.

WATER REGULATIONS
These regulations 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 recom-
mendations. The installation of an unvented hot water storage cylinder 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 offense to
install an unvented hot water storage system without notifying the Local Authority.

The installation and initial startup of the boiler must be by a CORGI Approved
Installer in compliance with the installation standards currently in effect, as well as
with any and all local health and safety standards i.e. CORGI.

The installation of this appliance must be in accordance with the relevant require-
ments of the current Gas Safety (installation & use) Regulations, the Local Building

Regulation and Health and Safety document No. 635 “Electricity at work regs. 1989”.

The appliance may be installed in any room or indoor area, although particular
attention is drawn to the requirements of the current I.E.E. Wiring Regulations, and
in Scotland, the electrical provisions of the Building Regulations applicable in
Scotland, with respect to the installation of the combined appliance in a room con-
taining a bath or shower.
Where a room-sealed appliance is installed in a room containing a bath or
shower the boiler and any electrical switch or appliance control, utilising
mains electricity should be situated so that it cannot be touched by a person
using the bath or shower.
The location must permit adequate space for servicing and air circulation around the
appliance as indicated in paragraph 2.4.
The location must permit the provision of an adequate flue and termination.
For unusual locations special procedures may be necessary.
BS 6798-1987 gives detailed guidance on this aspect.
A compartment used to enclose the appliance must be designed specifically for this
purpose. No specific ventilation requirements are needed for an installation within a
cupboard
This appliance is not suitable for outdoor installation.

The type C appliances (in which the combustion circuit, air vent intake and
combustion chamber are air-tight with respect to the room in which the appli-
ance is installed) can be installed in any type of room.
There are no limitations with respect to ventilation and the volume of the room itself.
The boiler must be installed on a solid, permanent wall to prevent access to the
electrical parts (when live) through the aperture on the back frame.
