3.1 Flue
The flue must be installed in accordance with the rules in
force in the countries of destination.
3.2 Flue Position and Length
The air and flue ducting connect to the top of the boiler
using the elbow which can be positioned in one of three
possible directions:
Rearward, left or right.
The standard flue is able to provide the duct length 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 and 3metre flue system and elbow/ terminal kit
must be used and can be supplied.
This is able to provide the duct length range shown in
diagram 3.3 for rear flue or 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 3.6.
The terminal must be exposed to the external air, the
position allowing free passage of air across it at
all times.
Car port or similar extensions of a roof only, or 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.
