If L>725mm then extension duct kit/s will be required - each kit

extends the flue by 750mm up to a maximum of 4m. See table

11.8 Measure and Cut the Ducts.

General: Cut the ducts as necessary, ensuring that the ducts are

square and free from burrs. Always check the dimensions before

cutting.

Measure the distance L. Refer to Fig.24 and 25.

The standard flue can be telescopically adjusted to any length

between 425mm and 725mm.

Fix the flue assembly together using the self-tapping screws

provided. Refer to Fig.22.

It will only be necessary to cut the standard assembly if

L<425mm. Cut the flue turret assembly and

the terminal

assembly by the same amount i.e L=350 - remove 75mm from

each

assembly.

Minimum side flue length = 335mm (accommodating a

10mm Service clearance and a 100mm wall)

Minimum rear flue length = 296mm (accommodating a

100mm wall)

If L is between 1175 - 1475mm (1 extension)

1925 - 2225mm (2 extension)

2675 - 2975mm (3 extension)

3425 - 3725mm (4 extension) it is

not necessary to cut the ducts.
