7.6 #800-1 Series Direct Vent
Termination Kit(s)
IMPORTANT: The horizontal heat shield must be installed when
incorporating minimum horizontal venting. Refer to Section 7.7 on
page 33.
IMPORTANT: The flex pipe is permanently attached to the exterior plate.
DO NOT ATTACH either #844-1 or #845-1 termination kit to fireplace (or
extension kit) until it has passed through the wall. Install termination
plates to the outside wall exterior.
IMPORTANT: The minimum bend radius to center is 6 in (152 mm)
required for installation of the flexible vent pipe. Care should be taken
when installing the flexible vent pipe to avoid a tight bend that may
cause abrasion or damage to the flexible pipe.
•
If terminating against vinyl siding, a vinyl siding protector must
be used (included with the #844-1 and #845-1 direct vent kits).
Follow instructions included.
•
Each #846-1 extension kit contains enough 5” & 8” flexible
aluminum pipe to extend chimney an additional 6 ‘ (1.83 m).
7.6.1 Assembly and Installation
1. Mount the required #800-WPT series wall pass through (G)
with the required 3” (76mm) top clearance and 1” (25mm) side
clearances to the exterior wall, and seal.
2. (OPTIONAL) insulate the wall-pass through with any unfaced
insulation products listed as non-combustible per ASTM E 136.
3. Apply a liberal bead of exterior sealant around outer edge of
termination box (A), placing assembly through the wall-pass
through in exterior wall. Place screws through the four holes (B),
securing it in place.
4. Form the 5” & 8” flexible aluminum pipes on termination kit
(#844-1 or #845-1), and if applicable, on each extension kit.
5. Gently pull 5” & 8” pipes down to the top of the fireplace, or if
applicable, the extension kit.
DO NOT stretch extension kit beyond 6 ‘ (1.83 m); DO
NOT stretch beyond what is required. It is very difficult to
decompress flex pipes once stretched.
6. Place a bead of sealant outside 5” flex pipe collar (C) (end with
EXTERNAL LIP) and sliding it into 5” pipe on extension kit or top
of fireplace (D). Secure with 3 evenly spaced screws.
7. Place a bead of sealant inside 8” flex pipe collar (E) (end with
the INTERNAL lip), sliding it over 8” pipe on top of fireplace (F).
Secure with 3 evenly spaced screws.
8. If additional extension kits are required, repeat Steps 4 and 5,
placing 5” & 8” pipes onto previous extension kit.
