7.6 #800-1 Series Direct Vent
Termination Kit(s) Installation
IMPORTANT: The vertical vent heat shield included with this fireplace
must be installed for all venting installations. Use the vent heat shield
assembly when installing the flexible pipe at the minimum bend radius
6” (152mm) to center.
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” (152mm)
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 #800-WPT3 Installation Instructions
IMPORTANT: The heat shield within the wall thimble must overlap
a minimum of 1-1/2” (38mm). An extension will be needed if going
through a thicker wall than 6-1/2” (165mm). Refer to BDM vent
manufacturer if wall extension is necessary.
1. Hand bend the (2) tabs on the top of the wall pass through at
the 1” (25mm) top required clearance. Hand bend the (6) tabs on
the sides and bottom of the wall pass through. Repeat for the
other section.
2. From the interior, install one section of the wall pass through.
Secure with (4) screws (not provided).
3. From the exterior, install the other section of the wall pass
through, overlapping the heat shields as necessary to
accommodate wall thickness. The sections must overlap a
minimum of 1-1/2” (38mm). Secure to exterior wall with (4)
screws (not provided).
4. Follow vent manufacturer installation instructions for vent
installation.
7.6.2 Assembly and Installation
1. Mount the required #800-WPT3 wall pass through (G) with the
required 1” (25mm) 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’ (1.83m); 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.
