5.5 flue Terminal cutting
Should the clearances above the appliance to the flue terminal
not allow for extensions, it is permitted to cut the flue terminal
ensuring the relationship of flue and air duct lengths are
retained.
5.6 flue extension completion
With the flue terminal positioned in the roof, measure the
length of the pipe required to complete the connection between
terminal and extension. If a telescopic length cannot be used,
then an extension pipe can be cut to the correct length. Cut the
flue to the desired length measuring from the ‘O’ ring end and
discard the plain end of the tube. The cuts must be square and
made free of burrs to allow correct assembly.
noTe: The flue pipe is 10mm longer than the air pipe.
Carefully push the terminal assembly upwards to allow room
for fitting the final flue piece. Fit a fixing bracket to the terminal
assembly. Pull the terminal assembly down and join to the flue
system. Ensure that the terminal is making a weather tight seal
on the weather collar. Secure the fixing bracket fitted to the
terminal to the roofing struts or a purpose made batton.
