Installation
3.9.1 Siting the Flue Terminal
The flue must be installed in accordance with
BS 5440:1 and the Building Regulations. Flue termi-
nals in carports and under balconies are to be avoided.
The terminal must be positioned so that it does not
cause an obstruction nor the combustion products a
nuisance. See fig. 15 and table 9.
The terminal will, at times, give out a plume of water
vapour and consideration must be given to this when
choosing a terminal position. Keep clear of security
lighting, activated by passive infra-red sensing heads.
If the terminal is less than 2 m above a surface to which
people have access then a guard must be fitted. The
guard must be evenly spaced about the terminal with a
space of 50 mm in each direction and fixed with plated
screws.
A guard Type K6 for the standard horizontal flue, can be
obtained from Tower Flue Components, Vale Rise, Ton-
bridge TN9 1TB.
