Rear Flue Preparation

1. Measure the wall thickness (Fig. 22) and to this

dimension add 60mm (2

3

/

8

in). 

2. Take the flue duct and mark off wall thickness

+ 60mm (2

3

/

8

in) from the swaged end of the duct

and cut to size (Fig. 23). (Use the tape provided

to give an accurate cutting guide by wrapping it

around the flue duct with the edge marking the

cutting line). 

3. Wall Thickness 280mm - 685mm 

(11in - 27in) -Take the telescopic air duct from its

pack. Open the air duct out to the wall thickness.

Using the tape provided seal the joints of the

three sections of the air duct, ensuring an overlap

of at least 30mm (1

3

/

16

in) at each joint (Fig. 24). 

NOTE: The seams of all three sections must

be in line.

4. Wall Thickness 100mm - 280mm (4in - 11in)

If the wall thickness is less than 280mm (11 in), it

will be necessary to cut the components of the air

duct to the appropriate size. Dispose of the centre

section, as this is not required (Fig. 25). 

5. Measure the wall thickness and subtract 30mm

(1

3

/

16

in) from this dimension. Cut the remaining

sections to this length, measuring from the

positions indicated in the diagram (Fig. 25). 

6. Engage the sections, one inside the other, then

open the assembly out to wall thickness. Tape the

sections together using the tape provided,

ensuring that the seal is good (Fig. 26). 

NOTE: The seams of both sections must be in

line.
