1.8.2 Installation of the horizontal flue
The flue gas adaptor (80/125 to 60/100) is suitable for lengths
upto 560 mm (see fig. 16).
For longer flue runs upto 12.0 m, extension air/flue ducts are
available (see page 9, table 3).
1.8.3 Flue duct preparation and assembly
z
Measure the flue length L. Refer to figures 17 and 18.
z
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 19.
Extension air duct - L-70 mm, flue duct - L-50 mm.
The measurement is from the formed end.
z
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.
z
Push the assembly through the wall and slide the turret
onto the flue connector. Refer to figure 15.
z
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.
