ƽ WARNING
Only use a sidewall air inlet cap supplied by the appliance
manufacturer or a rooftop air inlet cap supplied by either the vent
or appliance manufacturer. Using any other air inlet cap for single
unit installations or using a common air inlet cap for multiple
units with insufficient free area and/or protections from wind and
weather may result in operational problems and the spillage of
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 single unit installations with rooftop air inlet (see FIG. 2-8), you must order
the rooftop air inlet kit from the appliance manufacturer. The part number for
each VDK kit is listed by unit size in Table 2B. Purchase the flue pipe, rooftop
flue termination, and air inlet pipe locally.
There is no vent kit for combined air supply systems for multiple units. Make
sure the air inlet cap is properly sized. You must purchase this cap locally.
Venting of flue products
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.
