Fig. 4.3
a Measure the wall thickness T (fig. 43).
b Maximum available lengths of plastic liner:
Rear flue Maximum wall thickness (standard liner):
580 mm (T)
Maximum wall thickness (optional extension
liner) 828 mm (T).
Side flue Maximum distance from appliance side to
outer wail face: 680 mm (T+ C)
(with maximum wall thickness T as for rear
flues)
When measuring and cutting, always separate the inner
(flue) pipe wiih terminal from the outer (air) pipe.
c Cut the air pipe fig. 3.5 — cut from the plain end.
Rear Flue To overall length (L) oFT + 62 mm.
Side Flue To overall length (L) ofT + C+ 180mm
When cutting the air pipe, take care not to ovalise it and
remove the internal sharp edges produced when cutting
the pipe.
Drill again a hole (4 mm diameter) at a distance of 7mm
from the pipe end F) Fig 3 5 to [he hole center
d Cut the flue pipe — cut from the plain end.
Any Flue Cut off exactly the same amount as removed
from the air pipe.
Drill again a hole (3mm diameter) at a distance of 16
mm from the end of pipe to the centre of hole
e Cut the plastic- liner (S)
f Insert the flue pipe/terminal F) into the elbow A) and
secure with the specific screw.
g Insert the terminal into the plain, i.e. unchannelled
end of the air pipe E).
h IMPORTANT
Before inserting the air pipe into the elbow. LUBRI-
CATE THE ELBOW SEAL WITH OIL. then insert the air
pipe completely into the elbow.
If the elbow seal is not lubricated, it is not possible to
insert the air pipe into the elbow.
Take care to let the holes correspond, then insert the
clevis pin (fig 4.4).
i Pass the flue/air pipe assembly through the plastic
liner S).
j Fully insert the elbow A) into the fan socket, ensuring
that the elbow seal is correctly located.
k Check that the terminal protrudes the correct amount
from the wall face (fig. 4.3.).
