SP-41-L MANUAL REV#2 OCT 2017
Hussong Mfg. Co., Inc. • Kozy Heat Fireplaces
7.6 #700-2 Series Direct Vent
Termination Kit(s)
IMPORTANT: The vertical vent heat shield included with this
fireplace must be installed for every type of venting application.
IMPORTANT: Wall pass-through products (G) with the required
minimum 1 in (25 mm) clearance on all sides of the horizontal
vent pipe must be fully lined with unfaced insulation products
listed as noncombustible per ASTM E 136.
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.
IMPORTANT: The flex pipe is permanently attached to the
exterior plate. DO NOT ATTACH either #745-2 or #718-2
termination kit to fireplace (or extension kit) until it has passed
through the wall. Install termination plates to the outside wall
exterior.
• If terminating against vinyl siding, a vinyl siding protector
must be used (included with the #745-2 and #718-2 direct
vent kits). Follow instructions included.
• Each #746-2 extension kit contains enough 4” & 7” flexible
aluminum pipe to extend chimney an additional 6 ft (1.83 m).
7.6.1 Assembly and Installation
1. Fully line the wall pass-through with any unfaced insulation
products listed as non-combustible per ASTM E 136. Do not
proceed with installation until wall pass-through is insulated.
2. Mount the required wall pass-through (G) to the exterior wall,
and seal.
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 4” & 7” flexible aluminum pipes on termination kit
(#745-2 or #718-2), and if applicable, on each extension kit.
5. Gently pull 4” & 7” pipes down to the top of the fireplace, or if
applicable, the extension kit.
IMPORTANT: DO NOT stretch extension kit beyond 6 ft.
(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 4” flex pipe collar (C) (end
with EXTERNAL LIP) and sliding it into 4” pipe on extension
kit or top of fireplace (D). Secure with 3 evenly spaced
screws.
7. Place a bead of sealant inside 7” flex pipe collar (E) (end
with the INTERNAL lip), sliding it over 7” 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 4” & 7” pipes onto previous extension kit.
