2.FOR THE INSTALLER

2.1Installation instructions

This water heater must be fitted in a location which will permit the provision of an approved flue system and adequate ventilation.

A service clearance of 15 cm at the sides and rear of the unit and 60 cm at the front of the unit should be allowed for ease of servicing. Adequate distance must be allowed between the top of the unit and any obstruction or ceiling to allow the flue baffle and anode to be inspected, cleaned or in the case of the anode replaced if necessary.

The water heater must stand on a level surface resistant to heat and with sufficient strength to support the weight of the unit when full of water.

This water heater must not be installed in a bath room, bedroom or in a cup- board opening on to such rooms. This water heater must not be installed in any area where flamable materials are used or stored.

Insufficient ventilation may give rise to a risk of fire, explosion or suffocation. If in doubt consult the national and local regulations governing the installation of gas appliances or your local British gas service department.

2.1.1 Installation

The installation of this water heater should be carried out by a suitably qualified competent person. It is a criminal offence for unqualified persons to install gas equipment.

Installation should be carried out in accordance with all local authority and building regulations, local water authority and fire regulations and the following British standards: 5440, 5546, 6644, 6700, 6798 and 6891.

Some chemicals produce vapours which can cause rapid failure of thermocouples, burners and storage tanks if they are drawn into the combustion air supply.

Therefore if this water heater will be used to supply hot water to:

-hairdressers,

-dry cleaners

-industrial degreasing processes or any other area where compounds containing halogens are used and stored, care should be taken that all primary and secondary air is drawn from outside atmosphere free of such contaminents.

For further advise contact A.O. SMITH.

2.1.2 Water connections

A.O. Smith water heaters are suitable for connection to vented, unvented and pumped pressurised systems. In each case appropriate valves and fittings should be used to ensure the system complies with the requirements of the water by laws, and appropriate building regulations.

When fitting it is essential the rules of 'good practice' are applied at all stages of installation.

Vented systems

If the water heater is to be connected to a cold feed tank or cistern the hot water supply pipe must include an open vent which discharges over the cold feed cistern. The cold feed cistern must have an actual capacity of greater volume than the hourly recovery rate of the water heater(s) which it supplies.The minimum actual capacity is 50 gallons or 227 litres.

Unvented

To install an A.O. Smith water heater on an unvented cold water supply system a kit of valves and fittings listed by the water research centre and complying with part G3 of the current building regulations should be used. Installation should be carried out generally as shown on the following diagram.
