7.8 Flue
1. An internal fitting kit is available for installations where
the flue terminal is inaccessible from the outside. This
is available direct from Baxi Heating. Quote Part Nº
236441 when ordering.
2. The following guidelines indicate the general
requirements for siting balanced flue terminals.
Recommendations for flues are given in BS 5440 Pt.1.
3. If the terminal is fitted within 1 metre (39 in) of a plastic
gutter, within 500mm (19½ 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 (Fig. 9).
4. 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.
5. If a terminal is less than 2 metres (78¾ in) above a
balcony, above ground or above a flat roof to which
people have access, then a suitable terminal guard
must be provided.
