R95ESN: Installation, Start-up, Operating and Service and Maintenance Instructions
3. Outdoor openings shall be sized as follows:
a. Calculate the Ratio of all Indoor Space volume divided by
required volume for Indoor Combustion Air Method below.
b. Outdoor opening size reduction Factor is 1 minus the Ratio in a.
above.
c. Minimum size of Outdoor openings shall be the size required in
Outdoor Combustion Air Method above multiplied by reduction
Factor in b. above. The minimum dimension of air openings shall
be not less than 3 in. (80 mm).

CONDENSATE TRAP

Condensate Trap - Upflow Orientation
When the furnace is installed in the upflow position, it is not necessary
to relocate the condensate trap or associated tubing. Refer to
upflow condensate trap information. Refer to Condensate Drain section
for information how to install the condensate drain.

Condensate Trap - Downflow Orientation.
When the furnace is installed in the downflow position, the condensate
trap will be initially located at the upper left corner of the collector box,
as received from the factory. See the top image in
