NOTES:
1. Do not locate adjacent units with flue discharge
facing economizer inlet.
Minimum clearances to be:
• Front 48 in. to combustible surfaces (18 in. to
combustible surfaces when using accessory flue
discharge deflector). When not using roof curb
(1 in.) bottom of base pan to combustible sur-
faces• When not using roof curb (0 in.) bottom of
base rail to combustible surfaces.
• Right side, front and back sides (36 in.) for
proper condenser airflow•
• Overhead (60 in.) to assure proper condenser
airflow between unit and control box (42 in. per
NEC [National Electrical Code[)•
• Between units and ungrounded surface control
box side (36 in. per NEC).
• Between unit and block or concrete wall and
other grounded surfaces control box side 42 in.).
• Horizontal supply and return, (0 in.).
2. Downshot ducts designed to be attached to acces-
sory roof curb only. If unit is mounted side supply,
it is recommended the ducts must be supported by
cross braces as done on accessory roof curb.
3. With the exception of clearance for the condenser
coil, combustible surfaces, and the damper/power
exhaust as stated in Note 1, a removable fence or
barricade requires no clearance.
4. Dimensions are from outside of base rail. Allow
0-5/16[8] on each side for top cover drip edge.
5. Units may be installed on combustible floors made
from Class A, B, C roof covering material if set on
base rails.
