3.0 Site Requirements – Page 8
3.3 Flue Position
1. The siting of the balanced flue terminal must meet the
following conditions:
a. Where the flue terminal of the appliance is beneath any
opening (that is to say, any part of a window capable of
being opened, or any ventilation inlet or similar opening) no
part of the terminal shall be within 300mm (1 ft), measured
vertically from the bottom of the opening.
b. Where the flue terminal of the appliance is less than 2m (6
ft) above the level of any ground, balcony, flat roof or place
to which any person has access and which adjoins the wall
in which the flue terminal is situated, the terminal shall be
protected by a guard.
c. The guard must be screwed to the wall over the flue
terminal and be at least 50mm (2 in) clear of any part of the
terminal. A suitable guard is available direct from Baxi
Heating, Part No. 080266 (Fig. 5).
d. Not within. 300mm (1 ft) of ground level.
2. Fig. 4 shows the positioning of the flue terminal relative to
buildings and other structures.
3. If the outer face of the outside wall is of combustible
material (timber, etc.) a metal or other non-combustible
material plate should be fitted round the flue terminal so that
it extends not less than 50mm (2 in) around the terminal. A
179mm (7 in) square or a 230mm (9 in) diameter circular
plate will meet the requirement.
4. The flue should run horizontally, or with a slight drop to
the terminal, in order to prevent rain entry (Fig. 6).
3.4 Flue Dimensions
1. The standard appliance is supplied with flue ducting which
is adjustable to accommodate wall thicknesses from 248 mm
(93/a in) to 349mm (133h in).
2. Three further flue terminals are available as optional
extras to suit the wall thicknesses indicated in the table
opposite.
