INSTALLATION
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 5"(127mm) liner and outer 
 
8"(203mm) liner out enough to slip over 
the fl ue collars of the fi replace. (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 fi replace inner collar
and slip the 5"(127mm) liner down over it 
and attach with 3 supplied screws.
8) Do the same with the 8"(203mm) liner.
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.

out a square to mount 
the terminal to.
UNIT
INSTALLATION
with 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 11"(279mm) hole in the wall (inside 
dimension).
Note: A top clearance of 2-1/2"(64mm)
and side & bottom clearance of 
1-1/2"(38mm) must be maintained 
except that only a 1" (25mm) clearance 
is needed at the termination end. We 
recommend framing a 11"(279mm) x 
11"(279mm) (inside dimensions) hole 
to give structural rigidity for mounting 
the termination.
Note: If installing termination on a siding
covered wall, furring strips must be 
used to ensure that the termination 
is not recessed into the siding.
2) Level the fi replace and fasten it to the fram-
ing using nails or screws through the nailing 
strips.
3) Assemble the vent assembly by applying
Mill Pac to the 5"(127mm) inner collar of 
the termination and slipping the 5"(127mm) 
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 
temperature silicone to the 8"(203mm) fl ex 
pipe and slip it over the 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).
IMPORTANT: Do not locate termination 
hood where excessive snow or ice 
buildup may occur. Be sure to check vent 
termination area after snow falls, and clear 
to prevent accidental blockage of venting 
system. When using snow blowers, make 
sure snow is not directed towards vent 
termination area.
