Unit Clearances
*In situations that have multiple units, a 48” minimum clear-
ance is required between the condenser coils.
Clearance in accordance with local installation codes, the
requirements of the gas supplier and the manufacturer’s in-
stallation instructions.
Dégaugement conforme aux codes d’installation locaux,
aux exigences du fournisseur de gaz et aux instructions d’in-
stallation du fabricant.
Adequate clearance around the unit should be kept for safe-
ty, service, maintenance, and proper unit operation. A total
clearance of 75” on the main control panel side of the unit
is recommended to facilitate possible fan shaft, coil, electric
heat and gas furnace removal. A clearance of 48” is recom-
mended on all other sides of the unit to facilitate possible
compressor removal, to allow service access and to insure
proper ventilation and condenser airflow. The unit must not
be installed beneath any obstruction. The unit should be in-
stalled remote from all building exhausts to inhibit ingestion
of exhaust air into the unit fresh air intake.
NOTE:
If the 48” minimum is used on the control panel side
of the unit, a flue extension (MF# 220-GX-01) needs be to
installed to prevent flue gas recirculation.

of the curb perimeter, duct flanges and any exposed duct
connection frame. If gasket is loose, re-apply using strong
weather resistant adhesive.

ommended. Insulate and weatherproof all external ductwork
and joints as required and in accordance with local codes.
