Technical data

Dimension A mm. See Fig. 20.
Air duct length = A + 244 mm,
Flue duct length = A + 284 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 ring marked 77 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.
Fit 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.
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 duct into the flue bend. Ensure it is located correctly
against the stop. Drill two holes through the holes in the bend. See
Fig. 23.
Fit the air duct over the outside of the flue bend. Ensure it is located
correctly against the stop. Drill two holes through the holes in the air duct.
Disconnect the air and flue ducts from the flue bend.
Loosely assemble the flue duct into the air duct and engage in the
flue terminal.
From outside the dwelling pass the assembly through the hole in the wall.
From inside ease the flue duct sufficiently clear of the air duct to fit
the flue bend.
Apply a smear of silicone sealant around the outside of the flue duct.
Fit the flue duct into the flue bend and fix with the screws provided.
See Fig. 23.
Apply a smear of silicone sealant around the outside of the flue bend.
Assemble the flue bend into the air duct and fix with the two screws
provided.
Ensure the flue duct is correctly engaged in the flue terminal. 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.
The flue system is now assembled.
Temporarily support the flue system, ensure it is horizontal and the
flue bend will align with the flue position, located on the rear of the
inner casing. See Fig. 23.
Carefully ease the appliance into the position previously marked.
Ensure the flue position is correctly aligned with the flue centre-lines
previously marked
Fit the flue bend 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.
11.4.3.3 EXTENSION HORIZONTAL FLUE USING A SECOND
90° FLUE BEND.
(FLUE OPTION 5). See Fig. 12.5.
IMPORTANT: i) The two lengths of straight air duct when added
together must not exceed 2300 mm.
ii) A flue restrictor ring is not required.
iii) A flue adaptor is not required.
Refer to the instructions in Section 11.3.
