1. If your chimney termination is 8' or less from the s t o v e
top and doesn‟t require an extension kit, proceed to step
#7.
2. If your chimney termination will require one or more
extension kits (part #746), proceed with the following
steps. Each #746 extension kit contains enough 4"
& 7" flexible aluminum pipe to extend the chimney
an additional 6'.
3. Gently stretch the 4" & 7" flexible aluminum pipes on
the termination kit (#745 or #718) and on each ex tension
kit, if used, the length required so when all the sections
are connected together, the vent system length for your
venting configuration is attained.
4. Using your extension kit pieces, place a bead of sealant
outside the 4" flex pipe collar (C) - the end without
the lip, and slide it inside the 4" pipe on top of the fire
place (D). Secure with 3 evenly spaced screws.
NOTE: This connection is very difficult to remove
without damaging the collars once installed.
5. Place a bead of sealant outside the 7" flex pipe collar (E)
- the end without the lip - and slide it inside the 7" pipe on
top of the fireplace (F). Secure with 3 evenly placed
screws.
6. If additional extension kits are used, repeat steps #4 and
#5, placing the 4" & 7" pipes onto the previous extension
kit.
Referring to Figure 10:
7. Apply a liberal bead of exterior sealant around the outer
edge of the termination kit box (A), and, from the outside,
place the exterior wall assembly through the 9 ½ "
square hole. Place screws through the four holes (B)
securing it in place.
NOTE:
Attachment brackets are included with the termina-
tion kit. These optional brackets should be screwed, or nailed
(screws not provided) onto the top and bottom of the 9 ½ "
square hole, on the exterior of the house. The termination
plates then fit in between these brackets, and using the
screws provided, screw the brackets to the termination kit box
(A). Attach the vinyl siding protector.
7a.
OPTIONAL:
Place insulation between the 7" pipe and
the wall studs.
7b. The flexible termination kit includes an interior firestop
assembly (G) shown on Figure 4A, page #8, which is
installed on the inside wall
(over wall materials)
, around the
flexible pipe. Slide the firestop over the flex pipe with the
spacer legs toward the wall.
OPTIONAL: Apply a liberal bead of sealant
around the outside / wall side edge and place
over the 9 1/2” square opening.
7c. Secure each corner with a drywall screw.
8. Gently pull the 4" & 7" flexible aluminum down to
the top of the extension kit, or the top of the unit if
no extension kits were used.
9. Place a bead of sealant outside the 4" flex pipe collar
(C) and slide it inside the 4" pipe on top of the fireplace
(D). Secure with 3 evenly spaced screws.
NOTE: This connection is very difficult to remove
without damaging the collars once installed.
10. Place a bead of sealant outside the 7" flex pipe collar
(E) and slide it inside the 7" pipe on top of the fireplace
(F). Secure with 3 evenly spaced screws.
INSTALLATION OF THE #700 SERIES FLEXIBLE HORIZONTAL DV TERMINATION KIT(S)
NOTE:
#700 Series vent kits must be supported every 3 ft. to maintain proper rise. The flex pipe is permanently attached to the
exterior wall plate. Do not attach the #745 or #718 termination kit to the fireplace (or extension kit) until it has passed
through the wall. The termination plates should all be installed on the exterior of the outside wall.

18” minimum vertical
rise measurement is
