Minimum Vent Clearances
to Combustibles
* Clearances noted below must be maintained; except
when passing through a wall, ceiling or at the termination
where the use of a firestop or wall thimble reduces
clearance to 1-1/2" (38mm).
Horizontal Top* 3" (76mm)*
Horizontal Side 2 " (51mm)
Horizontal Bottom 2" (51mm)
Vertical Vent 2" (51mm)
Below are the recommended framing dimensions
(inside measurements) for the 4" x 6-5/8" rigid
vent terminations - for use with a firestop or wall
thimble.
Recommended Framed Opening Size
Vent Size Framing Size
4" x 6-5/8" 13-1/2" x 13-1/2"
1. Locate the unit in the framing, rough in the gas
(preferably on the right side of the unit). Locate
the centerline of the termination and mark wall
accordingly. Cut an square hole in the wall - see
chart (inside dimension).
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 inner flue collar of the termination and
slipping the inner flex liner over it at least 1-3/8"
(35mm). Fasten with the 3 screws (drilling pilot
holes will make this easier). Apply Mill-Pac to
the outer flex pipe and slip it over the outer flue
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. Slip the assembled liner and termination as-
sembly through the thimble making sure the
termination cap faces up (there are markings
on the cap indicating 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.
5. Pull the centre inner and outer flex liner out
enough to slip over the flue collars of the fire-
place. (You may wish to cut the liner shorter
to make it more workable.) Do not bend liner
more than 90°. The liners must slip over the
collars a minimum of 1-3/8".
6. Apply Mill Pac over the fireplace inner flue
collar and slip the inner flex liner down over it
and attach with 3 supplied screws.
7. Do the same with the outer flue collar and outer
flex liner.
8. 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.
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.
