NOTES:

1.

Refer to the condensate management and drain hose
plumbing for different configurations in this document. No
hose clamps are needed for the condensate pan hook up.

2.

Drip leg in the gas line must be installed.

3.

The furnace controls require correct polarity on the power
supply and a proper ground.

4.

Y & G must be connected to the control board for cooling
operation.

5.

To measure total static pressure add supply duct pressure to
the return duct pressure, add pressure drop across the ‘A’
coil, and add pressure drop across the filter. Ignore negative
signs on the readings.

6.

Inlet gas pressure for natural gas should be 7” and that for
propane should be 11” w.c. Nominal manifold gas pressure
is 3.5” for natural gas and 10” w.c. for propane.

7.

If thermoplastic evaporator ‘A’ coil drain pans are to be
installed in the up-flow/horizontal configuration, then extra 2”
minimum spacing may be needed to ensure against drain
pan distortion.

8.

External filters required on all configurations.

9.

Electrical entry is available on both sides of the casing.

10. All 33”, 95% furnaces are approved for single-pipe and 2-

pipe systems. For single pipe systems it is recommended to
install the combustion air coupling provided and install
approximately 18” of PVC pipe on the furnace.

11. Do not install an external condensate trap on these fur-

naces, as it will prevent the unit from operating correctly.

1. For venting purposes, one 90° sweep elbow is equal to 5 Ft. of venting length, one 90° standard elbow is equal to 10 equiva-

lent feet of vent length. Vent termination elbows are included in these calculations, minimum required vent length is 5 ft.

2. Must be changed if not in rise range.

This document does not replace the installation instructions, which must be referred to for
