INSTALLATION
termination and slipping the 4"(100mm) liner
over it at least 1-3/8" (35mm). Fasten with
the 3 screws (drilling pilot holes will make
this easier). Apply Mill Pac or high temper-
ature silicone to the 6-7/8"(175mm) flex
pipe and slip it over the 6-7/8" outer collar
of the vent terminal at least 1-3/8"(35mm)
and fasten with the 3 screws.
NOTE: Horizontal sections must be sup-
ported at intervals not exceeding
3 feet (0.9 meter). (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 1-3/8".
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 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 4"(100mm) liner and outer 6-
7/8"(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
o
.
7) Apply Mill Pac over the fireplace inner collar
and slip the 4"(100mm) liner down over it
and attach with 3 supplied screws.
8) Do the same with the 6-7/8"(175mm) liner.
9) Apply a bead of silicone between the thim-
ble and termination and around the outer
edge of the terminal at the wall in order to
keep the water out.
Note: To make the
installation more
aesthetically
pleasing, we rec-
ommend framing
out a square to
mount the termi-
nal to.
INSTALLATION
PROCEDURES
for Regency 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
10"(254mm) hole in the wall (inside dimen-
sion).
Note: A 1-1/2"(38mm) clearance around
the liner must be maintained ex-
cept that only a 1" (25mm) clear-
ance is needed at the termination
end. We recommend framing a
10"(254mm) x 10"(254mm) (inside
dimensions) hole to give structur-
al rigidity for mounting the termi-
nation.
Note: If installing termination on a siding
covered wall, furring strips must
be used to ensure that the termi-
nation is not recessed into the
siding.
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 4"(100mm) inner collar of the
Offset Chart
A poor draft, or down drafting can result from
high wind conditions near big trees or adjoin-
ing roof lines, in these cases, increasing the
vent height may solve the problem.
7) Ensure vent is vertical and secure the base
of the flashing to the roof with roofing rails,
slide storm collar over the pipe section and
seal with a mastic.
8) Install the vertical termination cap by twist-
locking it.
Note: Any closets or storage spaces,
which the vent passes through
must be enclosed.

IMPORTANT:
Do not locate termination
hood where excessive
snow or ice buildup may
occur. Be sure to check
vent termination area af-
ter snow falls, and clear to
prevent accidental block-
age of venting system.
When using snow blow-
ers, make sure snow is
not directed towards vent
termination area.
