Note!
Vertical flue pipes must not terminate within
600 mm of an opening window, an extraction
opening or any other ventilation opening.
The flue pipe must be fitted, or screened, in such a way
that ignition or damage to sections of the building are
avoided.
Terminal location
Directly under or above an opening or the horizontal to

dow etc.

Note!
In addition, the terminal should not be located
closer than 150 mm from a wall-opening provided
for e.g. a window.
Boundary flue terminations must as a minimum comply
with Building regulation part „J" 600 mm and should
also be in accordance with the Guide to Condensing
Boiler Installation which recommends 2.5 m from wall,
fence or boundary.
Where a plume diverter terminal is used this is
measured in the direction of the flow of products.

BS 5440–1: We recommend that the terminal of a
fan-assisted flue pipe system be positioned as follows:
a) At least 2 m from an opening in the building directly
opposite, and
b)so that the combustion products do not flow out at
right angles to a boundry.

1) Dimensions B, C and D:
K
These dimensions can be reduced to 25 mm without
having a negative effect on the output of the boiler.
In order to prevent the products and condensation
emission from impinging on any bordering surfaces,
the terminal should be extended as shown in Fig. 5.10.
2)Dimension F:
This dimension can be reduced to 25 mm without
having a negative effect on the output of the boiler.
In order to prevent the smoke and condensation
emission from impinging on any bordering surfaces,
however, a gap of 300 mm is recommended. For IE,
recommendations are given in the current issue of
the IS 813.

A ventilation opening in the room or inner room section
where the boiler is installed is not required .
Ventilating a compartment or enclosure
The boilers have a very high energy efficiency. As a
result of this, only small heat losses are produced at the
casing of the appliance. For this reason, cabinets and
enclosures in which the boiler is fitted do not need to
have permanent ventilation openings at the top and
bottom for cooling.
