Flue Installation
1.7.1
Siting the flue terminal
The flue must be installed in accordance with the recommen-
dations 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 appli-
cable 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.
