• Determine the point where the vertical air/flue duct
and terminal assembly will penetrate the roof.
• Fit the flexible pitched roof (Accy. No. 303 980) tile (1,
Accy. No. 303 980).

See section 2.11 for further details on the in-
stallation of extensions and elbows.
• Push the sliding sleeve (4) firmly into place on the ex-
tension.
• Join the vertical roof duct (5) to the extension (7).
• Join the sliding sleeve (4) to the appliance's connec-
tion piece (8).
Note
h
Using the sliding sleeve allows the appliance to
be easily removed and replaced without dis-
mantling the flue.
• Drill two holes 3 mm Ø through the air duct of the
flue/boiler clamp at the most convienient holes on the
air duct clamp. (Ensure that the drill does not pene-
trate the inner flue duct). Screw the clamp to the air
ducts of the flue assembly and the boiler using the
screws supplied.
• Ensure that any air duct clamps used are positioned
centrally and fixed to the air duct using the self tap-
ping screws supplied.
h Note
The air/duct clamp must not be screwed to the
bottom of the vertical air/flue duct and termi-
nal accessory to allow for any slight movement
in the roof structure.
• Ensure that at least one pipe clamp supports the air/
flue duct at each extension fitted.
