FLUE INSTALLATION

HORIZONTAL FLUE
WALL
(60/100mm diameter)
For vertical flues and 80/125mm horizontal flues,
please refer to separate instructions supplied with the
flue kit.
NOTE: to ease assembly of flue components,
189mm
apply silicone lubricant to sealing
surfaces.
Basic instructions for the 60/100mm diameter flue are
93mm
shown below.
MEASURING THE FLUE (Standard Flue):
Measure from the outside wall to the centre
line of the flue turret.
Subtract 93mm 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, then no cutting will be
required.
If the required length is less than 350mm the
standard telescopic flue can be modified, refer
to section 3.
If the required length is greater than 570mm,
then flue extensions will have to be used. Refer
to the 60/100 Horizontal Flue Instruction
manual provided in the flue extension kit.
Adjusting the standard terminal length:
2 Extend tube (A) by withdrawing from tube (B) to
achieve the flue length required, between
350- 570mm.
NOTE: Ensure that the TOP label of both
sections are aligned before securing the
two parts at the required length.
The flue terminal MUST be fitted with the
'TOP' label uppermost to allow the correct fit
and use of the plume management system.
Secure with screw provided and seal joint with the
aluminium tape supplied.
Reducing the standard terminal length:
3 Remove securing screws (C) to detach the
terminal assembly from the turret.
Slide terminal section (B) from the terminal
assembly and discard.
A
To use terminal (A) without cutting remove the
location lug (D) on the inner flue tube (E) and
remove any burrs.
To reduce the terminal length further:
4 Mark the length required for the terminal (F) as
shown (min. 130mm) and cut square, taking care
not to damage the tubes.
Remove any burrs and chamfer the outer edge of
the tubes to assist ease of connection and prevent
seal damage.
NOTE: The aluminium tape is not required when
reducing the terminal.
After cutting, the end must be square and
free from burrs to prevent damage to the
flue seals.
