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.
