11.4 INSTALL THE FLUE SYSTEM.
Because of site conditions it may be necessary to deviate from the
following method of installation. Joints must be sealed and fixed
where applicable.
11.4.1 STANDARD HORIZONTAL REAR FLUE.
(FLUE OPTION 1). See Fig. 12. 1.
IMPORTANT:
(i) A flue restrictor ring MUST be fitted in the flue
terminal or flues with a total straight length of
between 100 and 1000mm. See Fig. 24.
(ii) The flue adaptor MUST be fitted to connect the
flue system to the appliance. See Fig. 21.
AIR AND
FLUE DUCT PREPARATION.
The standard flue assembly, supplied with the appliance,
accommodates a maximum flue length of 500 mm measured from
the REAR of the appliance casing. See Fig. 19.
Measure accurately the distance from the rear of the appliance,
previously marked on the floor, to the outside surface of the wall.
Dimension A. See Fig. 19.
Air duct length = A + 188 mm
Flue duct length = A + 228 mm.
Cut air and flue ducts to length. Do not cut the drilled end of the air duct.
IMPORTANT: Fit the flue restrictor ring marked 72 into the flue
terminal. See Fig. 24.
Assemble the air duct to the flue terminal. Ensure it 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. 21.
Fit the flue duct into the extended end of the flue adaptor, ensure it
is located correctly against the stop. Drill two holes through the
holes in the flue adaptor. See Fig. 21.
Fit the air duct over the outside of the flue duct and onto the flue adaptor.
Ensure it is located correctly against the stop and the flue duct fits
into the flue terminal. Drill two holes through the holes in the air
duct. See Fig. 21.
Disconnect the air and flue ducts from the flue adaptor.
Apply a smear of silicone sealant around the outside of the flue
duct.Fit the flue duct into the flue adaptor and fix with the screws
provided. See Fig. 21.
Apply a smear silicone sealant around the inside of the air duct.
Re-assembly the air duct over the flue duct, ensure the flue duct fits
into the flue terminal and the air duct fits over the flue adaptor. Fix
with the screws provided.
The flue system is now assembled. See Fig. 21.
From inside or outside the dwelling pass the flue assembly through
the hole in the wall.
Temporarily support the flue system, ensure it is horizontal and will
align with the flue position on the rear of the inner casing.
Carefully ease the appliance into the position previously marked.
Ensure the flue position located on the rear of the appliance 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. 21.
Ensure it is located correctly against the stop. Fully tighten the
clamping screw accessible on top of the inner casing. See Fig. 14.
Note: Do not apply a smear of silicone sealant around the end of the
flue duct that fits into the flue terminal.
Make good the internal and external brickwork or rendering .
11.4.2 STANDARD HORIZONTAL SIDE FLUE ASSEMBLY
INCLUDING ONE 90° FLUE BEND.
(FLUE OPTION 2). See Fig. 12. 2.
IMPORTANT: A flue restrictor ring MUST be fitted in the flue terminal
or flues with a total straight length of between 100 and 1000mm.
See Fig. 24.
HORIZONTAL SIDE FLUE ASSEMBLY.
Measure accurately the distance from the side of the appliance
casing, marked on the floor, to the outside surface of the wall.
Dimension A. 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.
IMPORTANT: Fit the flue restrictor ring marked 75 into the flue
terminal. See Fig. 24.
Assemble the air duct to the flue terminal. Ensure it 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.
22.
Fit the flue duct into the flue bend. Ensure it is located correctly
against the stop. Drill two holes through the holes in the flue bend.
See Fig. 22.
Fit the air duct over the outside of the flue duct. 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 inside or 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. 22.
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. 22.
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. See Fig. 22.
Support the flue system temporarily so that it lines up with the flue
centre-lines previously marked.
Carefully ease the appliance into the position previously marked.
Ensure the flue position, located on the rear of the appliance, 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.
Ensure it is correctly located against the stop. Fully tighten the
clamping screw accessible on top of the inner casing. See Fig. 14.
Make good the internal and external brickwork or rendering.
