• Push the air/flue duct assembly
(1) including the flexible external
seal through the wall until the
seal clears the outside face of the
wall and pull air/flue duct back
towards the boiler until the
external seal touches the outside
wall (fig. 3.8 and fig 3.12).
• Ensure that the air/flue duct (1) is
centred in the hole and the
terminal is correctly positioned
with the inlet grille at the bottom
(fig 3.8 and fig 3.12).
• Slide the internal trim ring (2) over
the air duct until it is flush with the
wall (fig. 3.8).
• At this stage it is necessary to
prepare and fit the boiler onto the
hanging bracket – refer to the
boiler installation instructions.
• Fit the elbow (3) to the boiler by
inserting the spigot of the flue
elbow into the flue socket on the
boiler and secure using the 30
mm air duct clamp (4) provided
(fig. 3.8).
• Pull the air/flue duct back through
the wall such that the flue duct
fully engages into the flue elbow
socket.
• Fit the 48 mm air duct clamp (5)
ensuring that it is positioned
centrally (fig. 3.8).
• 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, securing in position with
a small amount of sealant if
required.
Caution!
If installed near a light, insects may
fly into the opening. Tell the
homeowner to clean the opening
regularly.
