INSTALLATION OF THE SE-DUCT FLUE
• Insert the end of the air/flue duct
assembly through the se-duct wall.
• Slide internal trim ring over the air
duct until it is flush with the wall.
• At this stage it is necessary to
prepare and fit the boiler onto the
hanging bracket – refer to the
boiler installation instructions.
• Before installing the flue elbow
onto the boiler flue outlet select
and fit the correct restrictor ring
(page 10) into the bottom of the
boiler elbow.
• Fit the elbow to the boiler by
inserting the spigot of the flue
elbow into the flue socket on the
boiler and secure using the air
duct clamp provided.
• Pull the air/flue duct back through
the se-duct wall such that the flue
duct fully engages into the flue
elbow socket.
• Fit the air duct clamp ensuring
that it is positioned centrally.
• Drill two holes 3 mm Ø through
the air duct of both the elbow/flue
and elbow/boiler clamps at the
most convienient holes on the air
duct clamps. (Ensure that the drill
does not penetrate the inner flue
duct). Screw the clamps to the air
ducts of the flue assembly, the
elbow and boiler using the screws
supplied.
• Slide the internal trim ring back to
the wall and seal and secure in
position.
