In a basement installation, the vent/flue pipe can be run
between joist spaces.
NOTE: If the vent pipe must go below a 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.
Vent/Intake Terminations for Installation of
Multiple Direct Vent Furnaces
If more than one direct vent furnace is to be installed vertically
through a common roof top, maintain the same minimum
clearances between the exhaust vent and air intake terminations
of adjacent furnaces as with the exhaust vent and air intake
terminations of a single furnace.
If more than one direct vent furnace is to be installed horizontally
through a common side wall, maintain the clearances as shown
in "Horizontal Venting of Multiple Furnaces" illustration. Always
terminate all exhaust vent outlets at the same elevation and
always terminate all air intakes at the same elevation.
