dimension).
Note: A 40mm clearance around the
liner must be maintained except
that only a 25mm clearance is
needed at the termination end.
We recommend framing a
254mm x 254mm
dimensions) hole to give
structural rigidity for mounting
the termination.
Note: To make
the installation
more
aesthetically
pleasing, we
recommend
framing out a
square to
mount the
terminal to.
2) Level the fireplace and fasten it to
the framing using nails or screws
through the nailing strips.
3) Assemble the flue assembly by
applying Mill Pac to the 100mm
inner collar of the termination and
slipping the 100mm liner over it at
least 35mm. Fasten with the 3
screws (drilling pilot holes will make
this easier). Apply Mill Pac or high
temperature silicone to the 175mm
flex pipe and slip it over the 175mm
outer collar of the flue terminal at
least 35mm and fasten with the 3
screws.

6) Pull the centre 100mm liner and
outer 175mm liner out enough to
