1. GENERAL DESCRIPTION AND INFORMATION

1.1 Information

1. Installation must be carried out by a competent person, and in accordance with the relevant

requirements of the current issues of:

A. Gas Safety (Installation & Use) Regulations. 1994
B. Building Regulations.
C. Building Standards (Scotland) Regulations.
D. I.E.E. Wiring Regulations.
E. Bye-laws of the local water undertaking.

Guidance on Installation is provided in this booklet, but due account must be taken of the detailed
recommendations of the current issues of:

BS 5440 Part 1: Flues.

BS 5440 Part 2: Ventilation.

BS 5546: Domestic hot water.

BS 6700: Water supply.

BS 6891: Gas supply.

For installation in timber framed buildings, refer to the British Gas Publication Guide for gas
installation in timber framed housing - REF DM2.

2. It is essential that the Water Heater be installed strictly in accordance with these Instructions and

the documents, detailed above.

3. To avoid the possibility of injury, care must be taken when handling sheet metal components.

1.02 Introduction

The Gas Multi Point water heater is a “room-sealed” appliance: it takes in the air required for com-
bustion and encloses all the combustion products in an hermetic compartment. The discharge of
fumes and intake of combustion air are managed through air/flue pipes that may be run horizontally
in all directions, or through a concentric flue running vertically or horizontally.

The main components of the water heater are:

-A compact heat exchanger in copper, formed by four pipes with external finning and internal
turbulence activators.

- An insulated combustion chamber to reduce heat loss and thus improve efficiency.

- Four stainless steel burners, an oxidation and thermal shock-resistant material specially developed
for this product.

-A fan to discharge combustion products and draw in combustion air.

S.p.A.

-A high limit thermostat

-A steel room-sealed compartment treated against corrosion, enclosing components.

- An air differential pressure switch which, to ensure safe operation, allows burner ignition only
when the fan functions normally.

-A newly-designed gas ignition valve assembly, comprising a fullly modulating gas valve and a
flame control device. (Ignition is by an intermittent pilot flame; at the moment a hot water tap is
opened, a pilot flame is sparked electronically which lights the main burners.)

-A flowmeter.

-A modulating device which controls the gas valve during use in response to the signal from the
flowmeter, the preset temperature and the desired flow rate (water temperature is kept constant
with no waste due to temperature fluctuation).

-A water temperature control which allows the user to set the desired temperature - between 40°C
and 55°C.

- Five LEDs: one green signalling that the water heater is on, and four yellow displaying water tem­perature.

-A temperature sensor.

-A expansion vessel 3 bar.
