I.S. 813 Domestic Gas Installations
Avoid installing the boiler where the air inlet can be polluted by
chemical products such as chlorine (swimming pool area), or ammonia
(hair dresser), or alkalin products (launderette).
Flue
Detailed information on ue assembly can be found in the
“Connecting the Flue” section.
The boiler must be installed so that the ue terminal is exposed to the
free passage of external air at all times and must not be installed in
a place likely to cause nuisance. It must not be allowed to discharge
into another room or space such as an outhouse or closed lean-to.
Condensing boilers have a tendency to form a plume of water vapour
from the ue terminal due to the low temperature of the ue gasses.
The terminal should therefore be located with due regard for the
damage or discolouration that may occur to building within the
vicinity and consideration must also be given to adjacent boundaries,
openable windows the min acceptable clearances are shown
opposite.
N
OTE: THE FLUE MUST NOT BE INSTALLED IN A PLACE LIKELY TO CAUSE A NUISANCE AND
POSITIONED TO ENSURE THAT PRODUCTS OF COMBUSTION DO NOT DISCHARGE ACROSS
A BOUNDARY
It may be necessary to protect the terminal with a guard, if this is the
case it will be necessary to purchase a stainless steel terminal guard.
Reference should be made to the Building Regulations for guidance.
Ventilation
The room in which the boiler is installed does not require speci c
ventilation. If the boiler is installed in a cupboard or compartment
ventilation is not required for cooling purposes.
Gas Supply
The gas installation and tightness testing must be in accordance with
the requirements of BS6891. Ensure that the pipe size is adequate for
demand including other gas appliances on the same supply.
Electrical Supply
The appliance requires an earthed 230V - 50 Hz supply and must be in
accordance with current I.E.E. regulations.
It must also be possible to be able to completely isolate the appliance
electrically.
Connection should be via a 3 amp double pole fused isolating switch
with contact separation of at least 3mm on both poles.
Alternatively, a fused 3 amp, 3 pin plug and unswitched socket may be
used, provided it is not used in a room containing a bath or shower, it.
It should only supply the appliance.
Water Supply
The boiler is suitable for sealed systems only. The maximum working
pressure for the appliance is 6 bar. All ttings and pipework for the
appliance should be of the same standard. If there is a possibility of
the incoming mains pressure exceeding 6 bar, particularly at night,
then a suitable pressure limiting valve must be tted.
The boiler is designed to provide hot water on demand to multiple
outlets within the property. If there is a requirement for greater
demands, for example if the boiler has several bathrooms and
cloakrooms, a vented or unvented hot water storage system may be
used.
Showers
Any shower valves used with the appliance should be of a thermostatic
or pressure balanced type.
Refer to the shower manufacturer for performance guidance and
suitability.
