Horizontal Termination - 4"
X 6-5/8" Venting (Flex Vent
Systems)
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" (25mm).
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.

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).
Note: If installing termination on a siding covered
wall, a vinyl siding standoff or vinyl fur-
ring strips must be used to ensure that the
termination 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 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

NOTE: Horizontal sections must be sup-
ported at intervals not exceed-
ing 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.
5. 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.
6. 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 90o. The liners must slip over the
collars a minimum of 1-3/8".
7. Apply Mill Pac over the fireplace inner flue collar
and slip the inner flex liner down over it and
attach with 3 supplied screws.
8. Do the same with the outer flue collar and
outer flex 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.
IMPORTANT: Do not locate termination
hood where excessive snow or ice
buildup may occur. Be sure to check
Furstrp.eps vent termination area after snow falls,
and clear to prevent accidental blockage
of venting system. When using snow
see also c34020a.eps
blowers, make sure snow is not directed
towards vent termination area.
