3 Flue and Ventilation
3.1 Flue
The flue must be installed in accordance with the rules in force in
the countries of destination. For UK, see current issue of BS5440
Part 1.
3.2 Flue Position and Length
The air and flue ducting connect to the top of the boiler using a flue
elbow and can be positioned in one of three directions:
rearward, left or right.
The standard flue will provide the range shown in diagram 3.1 for
a rear flue or diagram 3.2 for a side flue.
If a longer flue duct is required, do not extend the ductings. A 1, 2
or 3metre flue system and elbow/terminal kit must be used and can
be supplied. This will provide the range shown in diagram 3.3 for
a rear flue, diagram 3.4 for a side flue.
A Flue Bend Kit or Vertical Flue Kit can be supplied, with instructions.
3.3 Terminal Position
The minimum acceptable siting dimensions for the terminal from
obstructions, other terminals and ventilation openings are shown in
diagram 3.5.
The terminal must be exposed to the external air, the position
allowing free passage of air across it at all times.
Car ports or similar extensions of a roof only, or a roof and one wall,
require special consideration with respect to any openings, doors,
vents or windows under the roof. Care is required to protect the roof
if made of plastic sheeting. If the car port comprises of a roof and
two or more walls, seek advice from the local gas undertaking
before installing the boiler.
If the terminal is fitted within 600mm below plastic guttering, an
aluminium shield 1500mm long should be fitted immediately beneath
the guttering or eaves. If the terminal is fitted within 450mm below
painted eaves or a painted gutter, an aluminium shield 750mm long
should be fitted immediately beneath the guttering or eaves.
