Seal the joint with the tape provided.

If the flue system requires the addition of flue extension kits,
drill, seal and secure them with the self tapping screw and tape
provided. The completed flue system must not exceed 3
metres, see relevant part of diagram 4.1.

NOTE: Should any one of the flue sections require cutting to
obtain desired flue system length, cut the 1 metre extension kit
at the end opposite the expanded end.

If the boiler is not to be fitted for some time, cover the hole in the
wall.

NOTE: If a horizontal flue extension is required it must be used
in conjunction with the standard flue, see diagram 4.1.

IMPORTANT: When using the standard flue kit (either rear
outlet or top outlet fixing) or Easyfit, the terminal restrictor
must be fitted. This is not fitted for any other flue type/
arrangement, i.e. extension kits etc.

NOTE: There are three restrictors in the loose items pack,
use the one stamped “C” for the Micron 40FF.

Take the terminal restrictor and position the clamping bracket
making sure the clamping bracket nib protrudes in the slot of the
terminal restrictor and secure with locking screw, but do not
tighten, see diagram 4.6.

Engage the terminal restrictor on the flue terminal by hooking it
over the terminal end and engaging the clamping bracket
behind the inner ring of the terminal securing it by tightening the
locking screw, see diagram 4.6

4.7 Internal Access Flue

If access to the outside wall is not practical, the flue system can
be installed from inside. Use of the optional wall liner kit is
required.

4.8 Rear Flue Fixing

Fit the self adhesive foam seal provided in the flue pack around
the air duct at the position shown in diagram 4.1.

Make sure that the ductings do not slope down towards the
boiler.

Make good around the flue outside after installation of the boiler.

IMPORTANT: If the wall liner kit is used, the self adhesive foam
seal included in the wall liner kit must be used in place of the one
supplied with the flue pack, see diagram 4.5 for position of self
adhesive seal.

4.9 Top, Side Flue Fixing

Make sure that the ductings do not slope down towards the
boiler.

Make good the area around the flue inside and outside after
installation of the boiler.

4.10 Flue Positioning

Push the flue assembly into and through the hole such that it is
within the wall, and does not stick out into the room. Do not push
the flue assembly too far into the hole as it has to be pulled back
into the boiler and secured.
