10.4 EXTERNAL FITTING OF THE DUCT ASSEMBLY
Measure distance L.
RH Side flue duct length = L + 70 mm.
LH Side flue duct length = L + 250 mm.
Rear flue duct length = L + 155 mm.
Do not cut either the turret or the terminal assembly ducts unless
L =500 to 600mm.
1) Should L = 500 to 600mm then cut the terminal assembly
ducts reducing the length of the ducts to 200mm. Then cut each
extension to 200mm (see fig 15). Assemble the flue as described
below ensuring the correct length (L + 70 mm for RH side flues,
L + 250 mm for LH side flues, or L+ 155 mm for rear flues).
2) If L is within the range 127mm to 500mm then the flue can be
telescopically adjusted to the correct length (L + 70 mm for RH
side flue, L + 250 mm for LH side flue or L + 155 mm for rear
flue). The ducts are then fixed by drilling a pilot hole through the
hole in the air duct and screwing the self tapping screw provided
into the two ducts (see fig. 18).
3) If L is within any of the following ranges it will not be necessary
to cut the extension ducts:
0.88m to 1.10m, 1.63m to 1.85m or 2.38m to 2.5m.
Each extension duct must be connected to the first section of
flue or the previous extension duct by firstly fitting the inner flue
ducts together and pilot drilling and fixing (see fig. 19). Then the
outer air ducts can be similarly fixed using the pair of screws
provided. The flue terminal section can then be telescopically
adjusted and fixed as before (see fig. 18) ensuring the correct
length (L + 70 mm for RH side flues, L + 250 mm for LH side
flues, or L+ 155 mm for rear flues).
4) In the even of L not falling within any of the above ranges it
will be necessary to cut the FIRST extension length. The air
and flue duct lengths should both be reduced to the same length:
L - 240mm where one extension is used; L - 990mm with two
extensions and L - 1,740mm with three (see fig. 19). The flue
can then be assembled ensuring that the cut extension is fitted
to the turret duct assembly first and that the flue is adjusted to
the correct length of (L + 70 mm for RH side flues, L + 250 mm
for LH side flues, or L+ 155 mm for rear flues) (see fig 18).
