Domestic Gas Installations
Avoid installing the boiler where the air inlet can be polluted by
checmical products such as chlorine (swimming pool area), or
ammonia (hair dresser), or alkalin products (launderette).
Flue
Detailed information on flue assembly can be found in the
“
Connecting the Flue”
section.
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 may occur to
building within 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:
- A Directly below an opening, window, etc
300 mm
- B Horizontally to an opening, window, etc
300 mm
- C Below gutters, soils pipes or drain pipes
75 mm
- D Below eaves
00 mm
- E From vertical drain pipe or soil pipe
75 mm
- F From internal or external corner
300 mm
- G Above ground, roof or balcony level
300 mm
- H From a surface facing the terminal
500 mm
- I From a terminal facing a terminal
500 mm
- J Vertically from a terminal on the same wall
1500 mm
- K Horizontally from an terminal on the same wall
300 mm
- L Fixed by vertical flue terminal

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 the boiler is installed in a cupboard or
compartment ventillation 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 30V - 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 douple 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 shoild only supply the appliance.
