Fedders FV95A090 - Manual (Page 21)

Concentric venting terminal kits may be used for this series
furnace. They provide a means of obtaining combustion air
and exhausting products of combustion utilizing a single
penetration through the exterior wall. This can be useful
when there is limited wall space available. Kits are available
in 2” and 3” sizes. Read the instructions supplied with the kit
for additional installation instructions and details. The concentric venting terminal has the combustion air intake
built into the assembly. If using the concentric vent terminal,
there must be a minimum of 12” clearance to grade or antici-
pated snow level. There are no means available to raise the
terminal externally. If planning to use this terminal kit, see
The concentric vent termination kits may also be used in the
vertical position.
