INSTALLING THE
AIR/FLUE DUCT SLIDING
SLEEVE
☞
NOTE:
For installations where there is in-
sufficient movement to allow fitting
of the flue into flue outlet, a slid-
ing sleeve (Accy. No. 303 215) is
available. When using the sliding
sleeve both the air and flue ducts
of the last extension must be
shortened by a further 85 mm.
• Push the sliding sleeve (
1
) over the
cut end of the flue duct (
2
).
• Place the air duct clamp (
7
) over
the air duct.
• Pull back the sliding sleeve so that
it engages into the socket (
3
) of
the boiler (
4
). Ensure that the
sliding sleeve penetrates the
socket such that there is at least
20 mm engagement at both ends
of the sliding sleeve.
• Fit the air duct clamp over the air
ducts (
5
and
6
) of the
extension/terminal and boiler
outlet. Close the snap clamp.
• Drill two holes 3 mm diameter
through the air duct clamp (the
centre of the holes should be 6
mm from the edge of the clamp).
Ensure that the drill does not
penetrate the inner flue duct.
Screw the air duct clamp to the
air duct of the sleeve using the
screws provided.
• Complete the installation of the
flue as detailed in these
instructions.
