3.

 

Direction of airflow.

 

 

 

 

 

 

 

 

 

 

 

 

 

4. On vertical discharge units, ductwork to be attached to accessory roof curb only. For horizontal dis-

 

 

 

 

 

 

 

 

 

 

 

charge units, field-supplied flanges should be attached to horizontal discharge openings, and all

 

 

 

 

 

 

 

 

 

 

 

ductwork should be attached to the flanges.

 

 

 

 

 

 

 

 

 

 

 

 

5. Minimum clearance (local codes or jurisdiction may prevail):

 

 

 

 

 

 

 

 

 

 

 

 

a. Between unit, flue side and combustible surfaces, 48 inches. (18 in. when using accessory flue

 

 

 

 

 

 

 

 

 

 

 

 

discharge deflector.)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

b. Bottom of unit to combustible surfaces (when not using curb), 1 inch.

 

 

 

 

 

 

 

 

 

 

 

 

Bottom of base rail to combustible surfaces (when not using curb) 0 inches.

 

 

 

 

 

 

 

 

 

 

 

c. Condenser coil, for proper airflow, 36 in. one side, 12 in. the other. The side getting the greater

 

 

 

 

 

 

 

 

 

 

 

 

clearance is optional.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

d. Overhead, 60 in. to assure proper condenser fan operation.

 

 

 

 

 

 

 

 

 

 

 

 

e. Between units, control box side, 42 in. per NEC (National Electrical Code).

 

 

 

 

 

 

 

 

 

 

 

f. Between unit and ungrounded surfaces, control box side, 36 in. per NEC.

 

 

 

 

 

 

 

 

 

 

 

g. Between unit and block or concrete walls and other grounded surfaces, control box side, 42 in.

 

 

 

 

 

 

 

 

 

 

 

 

per NEC.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

h. Horizontal supply and return end, 0 inches.

 

 

 

 

 

 

 

 

 

 

 

 

6. With the exception of the clearance for the condenser coil and combustion side as stated in notes

 

 

 

 

 

 

 

 

 

 

 

5a, b and c, a removable fence or barricade requires no clearance.

 

 

 

 

 

 

 

 

 

 

 

7. Units may be installed on combustible floors made from wood or Class A, B, or C roof covering

 

 

 

 

 

 

 

 

 

 

 

material if set on base rail.

 

 

 

 

 

 

 

 

 

 

 

 

 

8. The vertical center of gravity is 1′-6″[457] up from the bottom of the base rail.
