Control™ line of upflow gas furnaces are designed for utility
rooms, closets, alcoves, or attics. Because of the low-profile
34 inch [864 mm] height, the upflow model can also be used
to satisfy most  applications. The design is certified by CSA.

• Two stages of operation to save energy and maintain optimal

comfort level.

• Furnace operates at 70% capacity for low-heat and 100%

capacity for high-heat.

• Compatible with single or two-stage thermostat. (For optimal

performance a two-stage thermostat is recommended.)

• Heat exchanger is constructed aluminized steel for maximum

corrosion resistance and thermal fatigue reliability.

quietest furnaces on the market today.

humidity control, quieter sound levels and year-round energy
savings.

bustion air may be piped to either the top or side of the cabi-
