15.2 LAS FLUE DUCT INSTALLATION OPTIONS
15.3 VERTICAL FLUE TERMINAL INSTALLATION OPTIONS
This type of installation can be carried out both on a fl at or pitched roof by fi tting a terminal, an appropriate weathering tile
and sleeve, (supplementary fi ttings supplied on demand).
For detailed instructions concerning the installation of fi ttings refer to the technical data accompanying the fi ttings.

SEPARATED FLUE-AIR DUCTING
This type of ducting allows to disengage exhaust fl ue gases both outside the building and into single fl ue ducts.
Comburant air may be drawn in at a different site from where the fl ue terminal is located.
The splitting kit consists of a fl ue duct adaptor (100/80) and of an air duct adaptor.
For the air duct adaptor fi t the screws and seals previously removed from the cap.
The fl ue duct must not fall and all horizontal runs must always rise at approximately 3° from the boiler.
Consideration for protection to exposed parts of the outlet duct where accidental touch may occur must be given.
Calculation of the total equivalent length:
The total equivalent length depends on the number and type of components in the fl ue system.
The total equivalent length is the addition of Air Duct Value + Flue Duct Value, plus the equivalent length of any bends.
The bend equivalences are:
45° = 0.25m
90° = 0.50m
ASSEMBLING THE FLUE SYSTEM
The pipe extensions can be cut to length if necessary. The cut end should be de-burred to prevent damage to seals when
assembling to a fi tting.
Apply soap solution to all seals to aid assembly.
Always use 80mm pipe clamps to secure/support the ducts. Secure the roof terminal with the pipe clamp supplied.
