WARNING

Fire Risk

Asphyxiation Risk

Maintain vent clearance to combustibles as speciﬁed.

•Do not pack air space with insulation or other materials.

•National building codes recommend using attic shield to keep loose materials/ insulation from contacting vent.

Failure to keep insulation or other materials away from vent pipe may cause ﬁre.

This appliance will operate correctly only if adequate ventia- tion is provided to allow proper draft to the system.

An outside air kit is available as an optional feature with this appliance. An outside air kit helps to decrease the amount of room air taken by utilizing outside air for combustion. We strongly recommend that it be installed.

Note: the outside air kit inlet thimble should be positioned in a manner that will not allow snow, leaves, etc. to block the inlet. A 3 ft. (.91 m) minimum height difference must be
