8. Install appropriate pipe sections until the vent run
reaches above the flashing. The enlarged ends of
the vent sections always face downward.
9. Install the storm collar and seal around the joints. (Fig.

10. Add additional vent lengths to achieve the proper
overall height.
11. Install termination cap.
Vertical Through Existing Chimney
The heater must be vented to the outdoors through an
existing masonry or prefabricated fireplace chimney
system through the roof.
The heater is approved to be vented to the outdoors
through any solid-fuel fireplace chimney that has been
constructed or installed in accordance with the na-
tional, Provincial/State and local building codes and is
constructed of noncombustible materials. For Venting
Requirements, refer to Page 10. Refer to Venting
Components on Page 12.
Fireplace Vent Termination Clearances
Observe the chimney-top vent termination clearances
specified in the instructions provided with those
components. Some considerations are:
• Obstructions or impediments to venting.
• Nearby combustible materials that could come into
contact with combustion exhaust gases.
• Other nearby openings (within 9” (230mm) through
which exhaust gas could reenter the building.
• All vegetation within 36” (914mm) that may interfere
with the draft.
NOTE: The collar extending down from the Termina-
tion base is the air intake collar. Use the flex vent liner,
marked with a blue line, to connect between this collar
and the
lower flue collar on the Transition Connector.
Also make sure the other flex vent liner is attached to the
upper Transition Connector collar and the Rain Cap. (Fig.
35)
1. Clean the top of the chimney as needed, to ensure a
good seal between it and the vent termination.
2. Slide the insulation sleeves provided in the termina-
tion kit over the two 3" flex liners (to be attached to
the 3" flue collar and cap of the termination assem-
bly).
3. Feed 3" flex vent from the bottom of the termination
assembly up through the 4" sleeve. Apply high-
temperature sealant to the rain cap collar, and slide
the flex vent over the end of the rain cap collar,
fastening with the clamp provided.
4. Slide the flex liner back through the 4" sleeve until
the rain cap/collar engages over the sleeve. Attach
the cap to the sleeve with three sheet metal screws
provided in the kit.
5. Apply high-temperature sealant over the air intake
collar, and attach the intake flex vent (blue) with a
clamp.
