1 Installation
1.8.2 Installation of the horizontal flue
The standard 100 mm diameter horizontal flue system is
suitable for lengths upto 560 mm (see fig. 13).
For longer flue runs upto 7.5 m, extension air/flue ducts are
available (see page 10, table 3).
NOTE
Use the wall-mounting template to help you
mark the position of the side flue opening
1.8.3 Flue duct preparation and assembly
Measure the flue length L. Refer to figures 14 and 15.
NOTE
The flue must be inclined to the boiler.
Mark of the lengths shown onto the ducts and cut the
length. The cuts must be square and free from burrs.
Terminal assembly outer (air) duct - L-70 mm, inner (flue)
duct - L-50 mm. The measurement is made from the ridge
at the terminal indicating the outer face of the wall.
Refer to figure 16.
Extension air duct - L-70 mm, flue duct - L-50 mm.
The measurement is from the formed end.
Assemble flue system completely. Push the ducts fully
together. The slope of the terminal outlet must be face
downwards.
The assembly will be made easier if a solvent free grease
is lightly applied to the male end of the ducts.
NOTE
An inner wall sealing plate is provided which
should be fitted to the ducts before assembly.
Push the assembly through the wall and slide the turret
onto the flue connector. Refer to figure 12.
Ensure that the turret is fully entered into the socket on the
boiler. From the outside fix the flue finishing kit to the
terminal and, after ensuring the duct is properly inclined
towards the boiler, fix the finishing kit to the wall.
If the terminal is within 2 m of the ground where there is
access then an approved terminal guard must be fitted.
The guard must give a clearance of at least 50 mm around
the terminal and be fixed with corrosion resistant screws.
