11 Flue Preparation and installation
11.4 Flue Attachment To Boiler
Lubricate the internal rubber seal of the flue outlet on the
boiler with a suitable lubricant. Push and twist the flue
adapter into position on top of the boiler and secure with
the four screws supplied, making sure the nib fits into
the locating slot in the boiler casing to ensure correct
orientation.
Fit the flue elbow with the securing collar (length 40-mm)
on to the flue adapter.
Secure the flue elbow by tightening the two screws on
the securing collar.
Draw flue assembly from wall, fit securing collar (length
70 mm), slide flue duct into flue elbow.
NOTE:
If the air and flue ducts have been correctly cut
to the instructions given in sections 11.1-11.2
the rubber sealing collar should fit flush with
the outside wall.
Position securing collar centrally over joint, tighten
securing screws. Drill and insert four self-tapping
screws, supplied, in the holes provided in the securing
collar.
Secure internal trim ring in position with a small amount
of sealant.
11.3 Flue Assembly
The flue assembly is a push fit design with securing
collars.
Remove all burrs from cut pipes.
Fig. 11.5 shows the components supplied in the standard
kit and the flue adapter.
Having cut the air and flue ducts as described in
sections 11.1- 11.2 assemble the flue as follows, the flue
can be fitted externally or internally.
Fit the rubber sealing collar behind the locating lugs on
the flue terminal, see diagram 11.5. Push the flue
assembly into the wall, externally or internally, initially
until the end of the assembly protrudes a short way from
the inside face of the wall. This will enable the internal
square trim ring to be positioned and allow the flue duct
to be drawn into the flue elbow after the flue adapter has
been fitted.
