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. (Not shown in Figure 11.12).
Each #846-1 extension kit contains enough 5” & 8” flexible aluminum pipe to extend chimney an additional 6 ft. (1.83 m).
11.1, Restrictor Assembly and Installation, on page 18 has information on restrictor installation in conjunction with venting
installation. 18.3, Restrictors, on page 43, has information on restrictor recommendations depending on burner flame
appearance and instructions on installation after venting is completed.
Refer to Figure 11.12, Assembly and Installation of #800-1 Series.
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.

Figure 11.12, Assembly and Installation of #800-1 Series
1. Mount the required wall pass-through thimble (G) (minimum 1 in. [25 mm] clearance) to the exterior wall and seal.
2. Apply a liberal bead of exterior sealant around outer edge of termination box (A), placing assembly through the wall thimble
in exterior wall. Place screws through the four holes (B), securing it in place.
3. Form the 5” & 8” flexible aluminum pipes on termination kit (#844-1 or #845-1), and if applicable, on each extension kit, as
shown in Figure 11.12. Then, gently pull 5” & 8” 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 recompress flex pipes once stretched.
4. 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.
5. 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.
6. If additional extension kits are required, repeat Steps 4 and 5, placing 5” & 8” pipes onto previous extension kit.
