￿WARNING Only use a sidewall air inlet cap supplied by the appliance manufacturer or a rooftop air inlet cap supplied by either the vent

3'	or appliance manufacturer. Using any other air inlet cap for single
MIN
	unit installations or using a common air inlet cap for multiple
12"	units with insufficient free area and/or protections from wind and
	weather may result in operational problems and the spillage of
MIN
	flue products. Spillage of flue products can cause personal injury
	or death due to carbon monoxide poisoning.
	For single unit installations with sidewall air inlet you must order the sidewall air
	inlet kit from the appliance manufacturer. The part number for each SVK kit is
	listed by unit size in Table 2B.

For venting flue products vertically to the outdoors, follow all requirements in the installation instructions for conventional venting in this manual.

Follow all clearance requirements in Vertical Vent Termination Clearances and

Location on page 17.

A barometric damper is not required in the flue on Vertical DirectAire™ installations if the draft is within the negative 0.02 to 0.08 inches w.c. required for proper operation. If the draft exceeds this range, install a barometric damper.
