Completion of Installation
With the flue terminal positioned in the roof the length of
the final pipe can be determined. If a telescopic length
cannot be used, then a standard flue length can be cut to
make 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), see diagram 9.23. 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.
