7.4 Flue Assembly
Fit and secure the flue elbow, see diagram 7.4.
Insert the flue and spacer into the air duct.
Fit the air box spigot plate in the correct position on the air box
according to left, right or rear flue.
Fit the air and flue duct assembly to the boiler, see diagram 7.5.
Note: Fully insert the air duct into the air box spigot. Make sure
the flue terminal is in the correct orientation, marked TOP and
the flue duct is engaged in the flue terminal.
Drill a hole, diameter as shown in diagram 7.6, in each side of
the air duct, through the holes in the air box. Secure the air duct
to the air box using the two screws provided in the loose items
pack.
Note: If side or front access is restricted then it may be
necessary to carry out the above operation after passing the
flue through the wall.
Seal around the joint between the air duct and the air box using
the tape provided in the loose items pack.
Place the flue assembly into the flue hole, to make sure that the
flue terminal is correctly positioned and sticking out the correct
distance from the outside wall face, see diagram 7.1 and the
appropriate diagram 7.2 or 7.3.
Remove flue assembly.
7.5 Internal Access Flue
If access to the outside wall surface is not practical, the flue
system can be installed from inside. Use of the optional wall
liner kit is required, see diagram 7.7.
