Note. All flue assemblies are designed for internal
installation, given that there is sufficient clearances
opposite to the flue for the installation of the flue.
For a wall thickness up to 300mm, provided there is
sufficient space available, the flue can be fully installed
from the inside.
For a wall thickness over 300mm the external flue hole
will need to be made good from the outside.
If there is insufficient clearance the flue can be installed
from outside.
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 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.
