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 alkaline products (launderette)
Flue
Detailed information on flue assembly can be found in Section
12 "Connecting the flue".
The boiler must be installed so that the flue 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 flue terminal due to the low temperature of the
flue gasses. The terminal should therefore be located with due
regard for the damage or discolouration that might occur to
buildings in the vicinity and consideration must also be given to
adjacent boundaries, openable windows should also be taken
into consideration when siting the flue.
The minimum acceptable clearances are shown below:
E
Fig. 11
A - Directly below an open window or other opening
B - Below gutters, solid pipes or drain pipes
C - Below eaves
D - From vertical drain pipes and soil pipes
E - From internal or external corners
F - Above ground on a public walkway or patio
G - From a surface facing a terminal
H - From a terminal facing a terminal
I - Vertically from a terminal in the same wall
J - Horizontally from a terminal in the same wall
K - Horizontally from an opening window
L - Fixed by vertical flue terminal
N : T
OTE HE FLUE MUST NOT BE INSTALLED IN A PLACE LIKELY TO
.
CAUSE A NUISANCE
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 specific
ventilation. If it is installed in a cupboard or compartment
permanent ventilation is not required for cooling purposes.
Gas Supply
The gas installation and soundness testing must be in
accordance with the requirements of BS 6891. 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.
