INTAKE
When installing a replacement boiler a new flue system is
delivered with the boiler as original flue set must be used and re-
using the existing boiler flue installation is strictly not acceptable
Design
Individual air supply and flue outlet pipes are used as standard. The material
approved for this application which MUST be used are:
Termination Of The Flue And Air
The flue and air pipes may terminate independently through any external
walls within the same dwelling except on opposing walls, within the
maximum lengths shown in graph below. (Alternatively a vertical flue pipe
termination is acceptable.)
The air pipe must have an elbow and 150 mm length of pipe directed
downwards with a termination grill fitted.
The air pipe can be situated at the side or beneath the flue pipe to a
minimum dimension of 140 mm (see Table.1). It must not be sited above the
flue pipe.
The flue and air pipes must extend by at least 40 mm from the wall surface.
Condensing boiler emit a visible plume of water vapour from the flue
terminal, this is normal. It is the responsibility of the installer to judiciously
select a terminal location that does not cause a nuisance.
If either the flue or air terminal is below a height of 2 m from ground level a
terminal guard must be fitted.
Note. Any veritcal termination MUST have the terminals fitted and the air
intake comply with the dimensions above
