All installations
– Cut the air duct square to the mark and remove all burrs
and sharp edges.
– Hold the air duct at the plain end, and slide the flue duct
(small duct) inside the air duct (terminal first) until it stops
against the terminal, then mark off the length to be cut
which leaves 20 mm protruding flue duct.
– Remove and cut the flue duct square to the mark and
remove all burrs and sharp edges.

FLUE AND TERMINAL INSTALLATION
3.4.1
Telescopic flue
– Push the flue duct assembly into the air duct until it stops
against the terminal.
– Fit the rubber sealing ring (E) into the swaged groove in
the air duct as shown in fig. 12. Ensure that it is the cor-
rect way around.
– From inside or outside the building, slide the duct assem-
bly into the wall until the sealing ring forms a good seal
against the outside wall.
– With reference to fig. 12, slide on the rubber ring (D),
check that the rubber sealing ring (E) is pulled up to the
wall and that the duct assembly is horizontal.
– Push the junction collar (B) over the air duct until the air
duct touches the inner part of the collar where the diame-
ter becomes smaller.
– Push the elbow socket into the junction collar and onto
the flue duct.
– Fit the jointing clamp (G) over the juction collar.
– Place the gasket (F) under the flange of the elbow and fit
the elbow onto the flue manifold, taking care to ensure
that the silicon seal on the elbow correctly engages and
forms a seal at its joint with the manifold.
– Secure the elbow onto the air/exhaust manifold using the
four screws provided.
3.4.2
Standard flue
– Push the flue duct assembly into the air duct until the
external swaged ring on the flue terminal stops against
the internal swage on the air duct (fig. 13).
– Fit the rubber sealing ring into the swaged groove in the air duct
as shown in fig. 14. Ensure that it is the correct way around.
– From inside or outside the building, slide the duct assem-
bly into the wall until the sealing ring forms a good seal
against the outside wall.
– With reference to fig. 14, slide on the aluminium retention
ring (D), check that the rubber sealing ring (E) is pulled up to
the wall and that the duct assembly is horizontal, then
secure the aluminium retention ring to the air duct using the
two screws (H) provided. Do not overtighten the screws.
– Push the junction collar (B) over the air duct until the air
duct touches the inner part of the collar where the diame-
ter becomes smaller.
– Push the elbow socket into the junction collar and onto the
flue duct.
– Fit the jointing clamp (I) over the junction collar.
– Remove the six fixing screws securing the sealed chamber
