VIII. PLANNING YOUR INSTALLATION
E. CENTRAL FURNACE APPLICATION
When installed with its own plenum and ductwork, the furnace will operate as a freestanding Central
furnace. See FIG. 8.
The 550-cfm blower provided is often sufficient to provide air distribution for smaller homes with short
duct runs. A second optional 550-cfm blower (DAKA #273), or a large side-mounted multi-speed
blower & filter box (DAKA #218), may be required for larger homes with longer ductwork (available
online at www.dakacorp.com).
CAUTION: DO NOT USE AS A FREE-STANDING RADIANT HEATER.
NOTE: A cold air return line must be installed between the cold air return filter box and the rooms
being serviced by the warm air outputs of the DAKA furnace.
