B
Mark off the lengths shown onto the pipe and cut to
length. The cuts must be square and free from burrs.
Terminal assembly outer (air) pipe - L-70 mm, inner
(flue) pipe - L-50 mm. The measurement is made from
the ridge at the terminal indicating the outer face of
the wall. Refer to figure 35.
Extension outer flue - L-70 mm, inner flue - L-50 mm.
The measurement is from the formed end.
Fig. 35 Flue terminal position
B
Assemble flue system completely. Push the flue fully
together. The slope of the terminal outlet must face
downwards (see fig. 35, item 1).
The assembly will be made easier if a solvent free
grease is lightly applied to the male end of the flue.
B
Push the assembly through the wall and slide the
terminal onto the flue connector. Ensure that the
terminal is fully entered into the socket on the boiler.
B
From the outside fix the flue finishing kit to the
terminal and, after ensuring the flue 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.
The flue must be inclined from the boiler.
