11.4.3.1 EXTENSION HORIZONTAL REAR FLUE.
(FLUE OPTION 3). See Fig. 12. 3.
IMPORTANT: i) Length of flue when measured from the rear of
the appliance casing must not exceed 3000
mm.
ii) A 75mm flue restrictor ring MUST be fitted into
the flue terminal. See Fig. 24.
iii) The flue adaptor MUST be fitted to connect the
flue system to the appliance. See Fig. 21.
HORIZONTAL REAR FLUE ASSEMBLY.
Measure accurately the distance from the rear of the appliance,
previously marked on the floor, to the outside surface of the
wall.Dimension A mm. See Fig. 19.
Air duct length = A + 188 mm,
Flue duct length = A + 288 mm,
Cut the air and flue ducts to length. Do not cut the drilled end of the
air duct that will fit adjacent to the appliance.
IMPORTANT: Fit the flue restrictor marked 75 into the flue terminal.
See Fig. 24.
ASSEMBLE THE AIR DUCTS.
Continue the installation by following the procedure as described in
Section 11.3.
If necessary, assemble and check the air duct length. Drill two holes
through the holes, in the expanded end of each air duct with the drill
provided. Disengage each air duct and apply a smear of silicone
sealant around of the air duct to seal the joint. See Fig. 23.
Reassemble and fix the air ducts together with the screws provided.
ASSEMBLE THE FLUE DUCTS.
Follow the procedure for measuring,cutting,sealing and fixing as
described in Section 11.3.
Note: If the extension is longer than 1500 mm a flue duct support
must be fitted before the ducts are finally assembled. The flue duct
support must be fitted half-way along the flue duct for effective
support. See Fig. 23.
ASSEMBLE THE FLUE DUCT INTO THE AIR DUCT.
Assemble the air and flue ducts into the flue terminal. Ensure the air
duct fits fully into the flue terminal and the restrictor ring is located
firmly between the end of the air duct and flue terminal. See Fig. 24.
Drill through the holes in the flue terminal into the air duct with the
drill provided.
Apply a smear of silicone sealant to the end of the air duct and fix
into the flue terminal using the screws provided. See Fig. 23.
Note: Do not apply a smear of silicone sealant around the end of the
flue duct that fits into the flue terminal.
Fit the flue adaptor to the air and flue ducts and assemble the flue
system. Follow the procedure as described in Section 11.3 and 11.4
to fit the flue adaptor and assemble the flue system.
The flue system is now assembled.
From inside or outside the dwelling pass the flue assembly through
the hole/holes in the wall/walls.
Temporarily support the flue system, ensure it is horizontal and will
align with the flue position, located on the rear of the appliance.
Carefully ease the appliance into the position previously marked.
Ensure the flue location is correctly aligned with the centre-lines of
the flue.
Fit the flue adaptor into the flue grommet located on the rear of the
inner casing. See Fig. 23.
Ensure it is located correctly against the stop. Fully tighten the
clamping screw accessible on top of the inner casing. See Fig. 14.
NOTE: i) Do not apply a smear of silicone sealant around the end
of the flue duct that fits into the flue terminal.
ii) Flues longer than 1500 mm must be adequately
supported. Air duct support brackets are available as
an optional extra.
iii) Make good the internal and external brickwork or
rendering.
11.4.3.2. EXTENSION HORIZONTAL SIDE FLUE.
(FLUE OPTION 4). See Fig. 12.4.
IMPORTANT: i) Length of flue when measured from the side of the
appliance casing must not exceed 3000 mm.
ii) A Ø77 flue restrictor ring MUST be fitted into the
flue terminal. Refer to Section 11.3 for the correct
size and the following instructions for fixing. See
Fig. 24.
iii) A flue adaptor is not required.
Measure accurately the distance from the side of the appliance
casing, marked on the floor, to the outside surface of the wall.
