Flue Installation
1.7.1 Siting the flue terminal
z
The flue must be installed in accordance with the
recommendations of
BS. 5440-1:2000
.
Pluming will occur at the terminal so terminal positions
where this could cause a nuisance should be avoided.
The air supply and the flue gas exhaust must meet the
applicable general regulations. Please consult the
instructions provided with the flue terminal kits prior to
installation.
The boiler MUST be installed so that the terminal is
exposed to external air.
It is important that the position of the terminal allows the
free passage of air at all times.
Minimum acceptable spacing from the terminal to
obstructions and ventilation openings are specified in
table 1.
If the lowest part of the terminal is less than 2 metres
above the level of the ground, balcony, flat roof or place
to which any person has access, the terminal must be
protected by a guard.
Ensure that the guard is fitted centrally.
The flue assembly shall be so placed or shielded as to
prevent ignition or damage to any part of the building.
