NOTES:
1. Dimensions in [ ] are in millimeters.
2. Center of gravity.
3. Direction of airflow.
4. On vertical discharge units, ductwork to be attached to
accessory roof curb only. For horizontal discharge units,
field-supplied flanges should be attached to horizontal dis-
charge 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,
36 in. [914].
b. Bottom of unit to combustible surfaces (when not using
curb), 1 in. [25]. Bottom of base rail to combustible sur-
faces (when not using curb) 0 inches.
c. Condenser coil, for proper airflow, 36 in. [914] one side,
12 in. [304] the other. The side getting the greater clear-
ance is optional.
d. Overhead, 60 in. [1624] to assure proper condenser fan
operation.
e. Between units, control box side, 42 in. [1067] per NEC
(National Electrical Code).
f. Between unit and ungrounded surfaces, control box
side, 36 in. [914] per NEC.
g. Between unit and block or concrete walls and other
grounded surfaces, control box side, 42 in. [1067] 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
′
-7
″
[483] for 008, 1
