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 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 200 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 600 mm
- I From a terminal facing a terminal 1200 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
ventilation is not required for cooling purposes.
