This appliance's venting system is room sealed or Direct Vent. This means that it does not require
room air for combustion but draws air from outside the building.

In the event of a puncture of the vent pipe or if an extension is needed couplers may be used. High
temperature sealant shall be applied to the ends of the coupler and the coupler shall then be inserted

coupler to the venting.
