2. Installation Requirements

2.1 Related Documents
The installation of the heater must be in accordance with the
relevant requirements of the Gas Safety (Installation and Use)
Regulations, Building Regulations and the Byelaws of the local
Water Undertaking. It should be in accordance also with any
relevant requirements of British Gas and local authority, and
the relevant recommendations of the following current British
Standard Codes of Practice :
BS 6891 : Specification for installation of low pressure
gas pipework up to 28 mm (Rl) in domestic
premises (2nd family gases).
BS 5546 : Installation of gas hot water supplies for
domestic purposes (second family gases).
BS 5440 : Flues and air supply for gas appliances of
rated input not exceeding 60 kW (1st, 2nd
and 3rd family gases).
Part 1 Flues
Part 2 Air Supply
2.2 Air Supply
IMPORTANT : This heater should be used in a well ventilated
room. An air vent direct to outside is required where the room
volume is less that 20 m
3
size in accordance with the following
table. In addition an openable window is required.
This heater must not be installed in a space less than 5 m3in
total volume.
This water heater is fitted with an atmospheric sensing device
which will turn off the gas supply to the pilot and burner, when
the oxygen in the atmosphere in the locality of the heater is
diminished and will not support safe combustion. It also pro-
tects the user if the heat exchanger fins become blocked.
It is therefore important that the heater is not located over a
cooker or in a position where the air supply is restricted or
contaminated.
The location must also permit space for servicing and air circulation around the appliance.
2.3 Gas Supply
An adequate sized gas meter must be connected to the service pipe. Where necessary British Gas will arrange for the existing meter to be checked or for a suitable meter to be installed.
On no account must any work be carried out on the gas meter
other than by British Gas or their specifically authorised
contractor.
Installation pipes should be fitted in accordance with BS 6891:
Pipework from the meter must be of adequate size. Pipes of a
smaller size than the gas connection should be not used,
The complete installation must be tested for gas soundness
and purged in accordance with BS 6891.
In addition to any other gas appliance installed in the premises, the meter should be capable of passing : 40 cu, ft/h of
natural gas.
2.4 Description of Operation of Special Components
2.4.1 Atmospheric Sensing Device
The thermoelectric circuit is fitted with a thermal switch located
on the front of the combustion chamber of the heater.When the
oxygen in the atmosphere in the locality of the heater becomes
diminished and is unable to support safe combustion, the products of combustion pass through an orifice in the front panel
and the increase in temperature is detected by the thermal
switch. When the switch is activated it interrupts the thermoelectric circuit and the pilot and main burner are extinguished.
2.4.2 Scale Reducer
The scale reducer is a diaphragm vessel forming part of the
water section. At the termination of a demand cycle the
contens of the heat exchanger are displaced into the vessel
and replaced with cold water.
2.5 Flue
These appliances are flueless. Protection is provided in the
form of the atmospheric sensing device (see Section 2.5.1).
They must not be operated continuously for more than five
minutes.
