INSTALLATION PROCEDURES
for Masport Direct Vent System (Flex)
1) Locate the unit in the framing,
rough in the gas (preferably on the
right side of the unit) and the
electrical (Junction block is on the
left side) on the left. Locate the
centerline of the termination and
mark wall accordingly. Cut a
254mm hole in the wall (inside
dimension).
Note: To make the installation more
aesthetically pleasing, we
recommend framing out a square
to mount the terminal to.
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.
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.
4) Separate the 2 halves of the wall
thimble and securely fasten the
one with the tabs to the outside
wall making sure that the tabs are
on top and bottom. Fasten the
other thimble half to the inside wall.
The thimble halves slip inside each

other and can be adjusted for 2 x 4
or 2 x 6 walls. The liners must slip
over the collars a minimum of
35mm.
5) Slip the assembled liner and
termination assembly through the
thimble making sure the termination
cap faces up (there are markings
on the cap that show which way is
(inside
up). This will position the
termination cap with proper down
slope for draining water. Fasten
the cap to the outer wall with the 4
supplied screws.
6) Pull the centre 100mm liner and
outer 175mm liner out enough to
slip over the flue collars of the
fireplace.
7) Apply Mill Pac over the fireplace
inner collar and slip the 100mm
liner down over it and attach with 3
supplied screws.
