1 Installation
1.7.8 Installation of the horizontal flue
The standard flue is suitable for lengths upto 660 mm
(see fig. 18). For longer flue runs upto 7.5 m, extension
air/flue ducts are available.
NOTE
Use the wall-mounting template to help
you mark the position of the side flue
opening
1.7.9 Flue duct preparation and assembly
Measure the flue length L. Refer to figures 19 and 20.
NOTE
The flue must be inclined from the boiler.
Mark off 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 21.
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 (see fig. 21, item 1).
The assembly will be made easier if a solvent free
grease is lightly applied to the male end of the ducts.
NOTE
An inner flue finishing kit 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 17.
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.
