How to fit sliding
sleeves
INSTALLING THE AIR/FLUE DUCT SLIDING SLEEVE
NOTE:
For installations where there is
insufficient movement to allow fitting
of the flue into flue outlet, a sliding
sleeve (Accy. No. 303 817) 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 over the cut
end of the flue duct.
• Place the air duct clamp over the
air duct.
• Pull back the sliding sleeve so that
it engages into the socket of the
boiler. 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 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 screw
provided.
• Refer back to the Instructions for
Installation and Servicing supplied
with the boiler to complete the
installation.
