Annual Fuel Utilization Efficiency based on DOE test procedures and according to FTC labeling regulations. Isolated combustion system rating for non-weatherized furnaces.
NOTE − Filters and provisions for mounting are not furnished and must be field provided.
 The same C33 uncased models match the furnaces shown but require an optional adaptor base or field fabricated transition. See C33 coil bulletin for additional information.
 Required for proper operation at altitudes over 4500 ft. (1370 m).
 Cleanable polyurethane frame type filter.
 Flue connection on the unit is 4 in. (102 mm) diameter. Most applications will require 5 in. (127 mm) venting and field supplied 4 x 5 in. (102 x 127 mm) adaptor. See Venting
Tables in the Installation Instructions for detailed information.
 Not for use with RAB Return Air Base or with 60C and 60D size units with air flow requirements of 1800 cfm (850 L/s) or greater. See Blower Performance Tables
for additional information.
 Required for proper operation at altitudes from 7501 to 10,000 ft. (2286 to 3048 m).
