Termination Kit(s)
IMPORTANT: The horizontal heat shield must be installed when using a
45° elbow off of the fireplace back. See Section 7.7 on page 28.
IMPORTANT: The flex pipe is permanently attached to the exterior plate.
DO NOT ATTACH either #844-2 or #845-2 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 #844-2 and #845-2 direct vent kits).
Follow instructions included.
• Each #846-2 extension kit contains enough 5" & 8" flexible
aluminum pipe to extend chimney an additional 6 ft (1.83 m).
