cannot be touched by a person using the bath or
shower.
Where installation will be in an unusual location then
special procedures may be necessary and BS.6798
gives detailed guidance on this aspect.
A compartment used to enclose the Heater MUST
be designed and constructed specially for this
purpose. An existing cupboard, or compartment,
may be used provided it is modified for the purpose.
Details of essential features of cupboard compart-
ment design, including airing cupboard installations
are given in BS.6798.
In siting the Heater, the following limitations MUST
be observed:
1.
The position selected for installation MUST allow
adequate space for servicing in front of the boiler
and for air circulation around the boiler.
2.
This position MUST also permit the provision of a
satisfactory balanced flue termination.
3.
This position MUST also permit the provision of a
satisfactory connection to the condensate drain.
Gas Supply
An existing meter (NG) and pipework should be
checked, preferably by the Gas Supplier, to ensure
that they are adequate to deal with the rate of gas
supply required.
Supply pipes should be sized to suit installation and
obtain a working pressure of 20 mbar (NG), 37 mbar
(Propane). Installation pipes should be fitted in
accordance with BS.6891.
A Natural Gas Heater must be connected to a
governed meter.
Conversion
The appliance is supplied for NG and can be con-
verted to LPG by the addition of an Propane Orifice
which is supplied with the heater. See page 12 for
conversion instructions.
Flueing
Only flue components specified by the Manufacturer
should be used with these appliances. Detailed
recommendations for flueing are given in BS.5440:
The following notes are intended for general guidance.
1.
Be aware of the plume from the flue and the
wetting effect it can have to adjacent property.
2.
The flue can be taken upwards, left, right or to
the rear of the appliance, but
never
downwards.
3.
The Heater is supplied separate to the chosen
flue set. It can be fitted with up to 20 metres
equivalant length of Concentric flue, see the Flue
Section on page 9 & 10 for examples and
parts selection.

IMPORTANT.
It is absolutely ESSENTIAL to ensure in practice,
that products of combustion discharging from the
terminal cannot re-enter the building, or any other
adjacent building, through ventilators, windows,
doors, other sources of natural air infiltration or
forced ventilation/air conditioning.
If this should occur, the appliance MUST be turned
OFF IMMEDIATELY and the Local Supplier con-
sulted.
Air Supply
It is NOT necessary to have a purpose
provided air
vent in the room or internal space in which the boiler
is installed.
Where the boiler is installed in a cupboard or com-
partment
no
air vents are required.
However the user may wish to ensure that it is
ventilated to provide air circulation.
Outdoor Heaters
These Heaters are certified for outdoor installation,
when equipped with the approved terminal.
WARNING:
The heater shall not be located in an area
where water sprinklers, or other devices, may cause
water to spray through the cabinet openings and into
the heater. This could cause heavy internal rusting or
damage some electrical components, and this would
void the warranty.
It is recommended that periodically the casing is
cleaned and sprayed with WD40 or similar liquid, and
any exposed threads are lightly coated in grease.
