In a basement installation, the pipes may be run between the joist
spaces. If the pipes must go below the joist and then up into the
last joist space to penetrate the header, two 45° elbows should be
used to reach the header rather than two 90° elbows.

If more than one direct vent furnace is to be installed vertically
through a common roof top, maintain the same minimum clear-
ances between the exhaust vent and air intake terminations of
adjacent units as with the exhaust vent and air intake terminations
of a single unit.
If more than one direct vent furnace is to be installed horizontally
through a common side wall, maintain the clearances as in the
following figure. Always terminate all exhaust vent outlets at the
same elevation and always terminate all air intakes at the same
elevation.

This kit is to be used with 2” or 3” direct vent systems. The vent kit
must terminate outside the structure and may be installed with the
intake and exhaust pipes located side-by-side or with one pipe
above the other. This kit is NOT intended for use with single pipe
(indirect vent) installations.
Refer to the directions furnished with the Side Wall Vent Kit
(p/n 0170K00000S) for installation specifications.
