7.7 #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: 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.
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 #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).

wall, and seal.
(OPTIONAL) insulate the wall thimble with any unfaced
insulation products listed as non-combustible per ASTM E
136.
2.
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.
