Flue
An internal fitting kit is available for installations where the
flue terminal is inaccessible from the outside. -(Part No
236441). This is available from merchants or direct from Baxi
free of charge.
The following guidelines indicate the general requirements
for siting balanced flue terminals. Recommendations for
flues are given in BS 5440 Pt.1.
If the terminal is fitted within 1 metre (39 in) of a plastic
gutter, within 500mm (19 ½ in) of a painted eave or a
painted gutter, an aluminium shield of at least 1 metre (39 in)
long should be fitted to the underside of the gutter or painted
surface. An air space of 5mm (3/16 in) should be left
between shield and gutter.
If the terminal discharges onto a pathway or passageway,
check that combustion products will not cause a nuisance
and that the terminal will not obstruct the passageway.
