MEASURING THE FLUE (STANDARD FLUE)
▶ Measure from the outside of the wall to the centre line of the flue turret
to determine length L.
▶ Subtract 50mm from the length L to give the correct dimension to the
flue elbow connection.
▶ If the length L falls within the telescopic range of 350 to 570mm or
570 to 790mm using the longer telescopic flue, then no cutting will be
required.
▶ If the required length is less than 350mm the standard telescopic flue
can be modified, refer to fig. 38.
▶ If the required length is greater than 570mm, then the longer
telescopic flue, giving a range of 570 - 790mm, can be used
▶ If the required length is greater than 790mm, then flue extensions will
have to be used. Refer to the 60/100 Horizontal Flue Instruction
manual provided in the telescopic flue kit.
▶ Refer to section 3.9 for flue options.
Adjusting the telescopic flue length:
Fig. 37 Standard telescopic flue
Extend tube (1) by withdrawing from tube (2) to achieve the flue length
required, between 350 - 570mm.
Secure with screws provided and seal joint with the aluminium tape
supplied.
4.6.2
REDUCING THE TELESCOPIC FLUE LENGTH
The flue terminal MUST be fitted with the 'TOP' label uppermost to allow
the correct fit and use of the plume management system.
Fig. 38 Reducing the standard terminal
▶ Remove securing screws (3) to detach the terminal assembly from the
turret.
▶ Slide terminal section (2) from the terminal assembly and discard.
▶ To use terminal (1) without cutting remove the location lug (4) on the
inner flue tube (5) and remove any burrs.
To reduce the flue length further:
Fig. 39 Further reduction
▶ Mark the length required for the terminal as shown (min. 130mm) and
cut square, taking care not to damage the tubes.
▶ Remove any burrs and chamfer the edges of the tubes to assist ease
of connection and prevent seal damage.
▶ Push the terminal fully home into the turret and secure the terminal
end with the screws (3), ensure that the “TOP” label is facing up.

INSTALLING THE TELESCOPIC FLUE:
Refer to figure 40.
1. Set the flue length to the distance required, secure with screws
provided.
2. Seal the joint with the aluminium tape provided.
3. Slide the inner wall seal onto the terminal.
4. If fitting from inside the building; slide the outer wall seal onto the
terminal.
Fig. 40 Telescopic flue
Refer to figures 41 & 42.
1. Remove the three inner flue tube retaining screws (2).
The inner tube will be held in place in the appliance.
2. Check the boiler flue seal is correctly seated and apply silicone
grease.
3. Position terminal through the flue opening in the wall to the outside of
the building by the distance shown.
- or -
If the outer seal is already fitted, push the terminal through the hole
until the outer seal is outside and then pull the terminal back to the
wall to seal.
4. Align the flue turret to the boiler flue outlet with flat facing (1) to the
rear of the boiler.
The flue turret should be pushed straight down, on to the boiler.
Ensure that the “TOP” label is facing up before securing
the flue section to the turret.
