Installation
3.9.3 Flue duct preparation and assembly
Measure the flue length L. Refer to fig. 21, 22.
Fig. 21 Flue length - rear
Fig. 22 Flue length - side
Mark off the lengths shown onto the ducts and cut to
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 fig. 23.
Extension air duct - L- 70mm, flue duct - L- 50 mm.
The measurement is from the formed end.
Fig. 23 Flue terminal position
Assemble flue system completely. Push the ducts fully
together and clamp in the positions. The slope of the
terminal outlet must face downwards.
The assembly will be made easier if a solvent free
grease is lightly applied i.e Vaseline, to the male end of
the ducts.
NOTE: An inner wall sealing plate is provided
which should be fitted to the ducts before assem-
bly.
Push the assembly through the wall and fix the turret to
the appliance with the clamp. Refer to fig. 24.
Fig. 24 Flue turret
Ensure that the turret is fully entered into the socket on
the boiler. From the outside fix the outer wall plate to the
terminal and, after ensuring the duct is properly i nclined
towards the boiler, fix the plate 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 an be fixed with corrosion resistant
screws.
