NOTES:

1. If the furnace is equipped with NOx screens and is to be
used with LP (propane) gas, the screens must be removed
prior to start-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. External filters required on all configurations.

6. Electrical or gas entry is available on both casing sides.

7. 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.

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

3.5” for natural gas and 10” w.c. for propane at max. input.

9. For downflow application the vent blower must be rotated 90
left or right as shown.

* Other airflows are available. see Tech guide for all CFM options.

Inducer blower may be rotated 90° either way to vent through casing side, as shown below.

These are Category I units and the vent system must be installed in accordance with latest
edition of the National Fuel Gas Code, Z223.1/NFPA 54, or in Canada, CSA B149.1.

These furnaces should be vented with type B vent pipe. No single - wall vent pipe or
vent connectors are allowed. This furnace be vented into a masonry chimney.

These are modulating furnaces which vary the gas input between 50% and 100% of full rate.
To make it easier to check that the furnace is not overfired or underfired, put the furnace in
TEST MODE and clock the gas meter. See Installation Booklet for details of TEST MODE.
