FLUE MEASURING & CUTTING
Flue bends:
1 Connecting flue bends increases the
effective pipe length and an allowance
must be made for the different connectors.
The example opposite shows dimensions
for two 90° bends connected to a standard
flue extension.
Adjusting the standard terminal length:
2 Extend tube (A) by withdrawing from
tube (B) to achieve the flue length required,
310- 530mm.
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 connector.
Slide terminal section (B) from the
terminal assembly and discard.
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
(A) 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.
Reducing extended flue tube length:
Only cut flue extension & not flue terminal.
5 Mark flue extension (F) to the required
distance measuring from the socket end
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.
