3.4 FLUE AND TERMINAL PREPARATION
If the wall thickness is less than 0.5 m (19 in) the flue/air duct
may be fitted without access to the outside wall providing that
the optional wall liner kit is used. (This consists of a steel pipe,
0.5 m long and 129 mm outside diameter with a 1 mm wall
thickness).
3.4.1 Flue/air duct lenghts
– Determine whether an extension duct is required with ref-
erence to the Z dimension shown in figs. 10-11-13. Alter-
natively max. flue lenghts information is given in
Table 7.
Z Dimension UP TO 945 mm.
No extension duct required.
Z Dimension greater than 945 mm and up to 1,760 mm.
One extension duct kit required.
Z Dimension greater than 1,760 mm and up to 2,575
mm. Two extension duct kits required.
Z Dimension greater than 2,575 mm and up to 3,000
mm. Three extension duct kits required.
Z Dimension greater than 3,000 mm.
NOT PERMITTED.
– If no extension ducts are required, procede to 3.4.2.
– If an extension duct or ducts is/are to be used, the flue and
air ducts should be joined before proceeding to the next sec-
tion. The extension ducts should be joined to each other and
to the standard ducts using the following procedure (fig. 9);
– For the flue ducts in turn, push the plain end of the stan-
dard and (if using two or three extensions) extension duct
into the swaged end of the extension duct(s).
– Push an air duct in to the clamp. Join the air ducts (larger
ducts) and tighten the screws an the clamp to connect
them.
3.4.2 Cutting the flue/air duct to the correct length
Rear flue outlet (Only - fig. 10)
– Select the air duct (larger duct) and starting at the formed
end, ‘mark off’ the length to be cut which is the wall thick-
ness
X + 130 mm (5

/
8
in).
Side flue outlet (Only - fig. 11)
– Select the air duct (larger duct) and starting at the formed
end, ‘mark off’ the length to be cut which is the wall thick-
ness
X + the clearance Y plus 180 mm (7
