* Based on altitude of 0 to 2000 ft.
† Required filter sizes shown are based on the larger of the ARI (Air Conditioning and Refrigeration Institute) rated cooling airflow or the heating airflow velocity of 300
ft/minute for high-capacity type. Air filter pressure drop for non-standard filters must not exceed 0.08 in. wg.

* Capacity of pipe in cu ft of gas per hr for gas pressure of 0.5 psig or less. Pressure drop of 0.5-in. wg (based on a 0.60 specific gravity gas). Refer to Table C-4, National
Fire Protection Association NFPA 54.
† This length includes an ordinary number of fittings.
8. Check for gas leaks at the field-installed and factory-
installed gas lines after all piping connections have been
completed. Use soap-and-water solution (or method speci-
fied by local codes and/or regulations).
IX. INSTALL DUCT CONNECTIONS
The unit has duct flanges on the supply- and return-air openings on
the side and bottom of the unit. For downshot applications, the
ductwork connects to the roof curb (See Fig. 2 and 3 for
connections sizes and locations).
A. CONFIGURING UNITS FOR DOWNFLOW (VERTI-
CAL) DISCHARGE

2. Remove return duct cover located on duct panel by breaking
connecting tabs with screwdriver and a hammer (See Fig.
10A & 10B).
3. To remove supply duct cover, break front and right side
connecting tabs with a screwdriver and a hammer. Push
louver down to break rear and left side tabs (See Fig. 10A
& 10B).
4. If unit ductwork is to be attached to vertical opening flanges
on the unit composite base (jackstand applications only), do
so at this time.
CAUTION: Collect ALL screws that were removed. Do
not leave screws on rooftop as permanent damage to the
roof may occur.
5. It is recommended that the unit base insulation around the
perimeter of the vertical return-air opening be secured to the
unit base with aluminum tape. Applicable local codes may
require aluminum tape to prevent exposed fiberglass.
