4 Flue

NOTE:

The flue must be installed in accordance with the current issue of BS5440 Part 1.

Important. The flue must be installed with a fall of 35mm per metre (2o) towards the boiler, see diagram 4.1.

It is of no advantage to exceed this angle (2o) indeed sealing of the fan to flue elbow may become more difficult as the angle is increased.

The air and flue duct connect to the top of the boiler using an elbow which can be positioned to the side or rear.

The rear and side flue assemblies are designed for internal installation, but if necessary, due to insufficient clearances (boiler/flue terminal location) they can be installed from the outside.

For a wall thickness up to 300mm the flue can be fully installed from the inside.

For a wall thickness over 300mm the external cut hole will need to be made good from the outside.

The standard flue is able to provide the duct lengths as shown in diagram 4.2 for a rear flue and diagram 4.3 for a side flue.

If a longer flue duct is required, do not extend the ductings. A 1, 2 or 3metre long flue system and terminal can be supplied.
