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: 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 (inside
dimensions) hole to give
structural rigidity for
mounting the termination.
Note: To make the installation
more aesthically 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 vent 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 he 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 vent
terminal at least 35mm) and asten
with the 3 screws.
NOTE: Horizontal sections must be
supported at intervals
exceeding 1 metre. (Flame picture
and performance will be affected by
sags in the liner).

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 s 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. (You may wish to
cut the liner shorter to make it
more workable.) Do not bend
liner more than 90°.
7) Apply Mill Pac over the fireplace
inner collar and slip the 100mm liner
down over it and attach with 3 supplied
screws.
8) Do the same with the 175mm liner.
not
9) Apply a bead of silicone between
the thimble and termination and
around the outer edge of the
terminal at the wall in order to
keep the water out.
NOTE: Installation and annual
service must be performed
by a qualified installer, service
agency or the gas supplier to
validate warranty.
