Note 1: 208V or 240V systems are factory configured to be field connected to multiple, single phase line
voltage circuits. If single feed to element and blowers/system controls circuit is desired, an optional
single feed kit is available to order. Connection to 3-phase power is acceptable and can improve
phase balancing.
Note 2: Because 277/480V and 347/600V systems are configured for single feed, three phase line voltage
connections only, a step down transformer must be field installed.
Note 3: The size and heating ability of the system required for an installation is dependent on the heat loss
of the area and hours available for charging. In addition, if the system is not installed within the
heated area, heat lost statically must be taken into account when sizing. Contact Steffes Corpora-
tion for assistance in selecting an appropriately sized system.
Note 4: The indoor coil or outdoor compressor of an air conditioner or heat pump are not included with the
furnace. A return air plenum for the 6140 is configured to house an indoor coil and can be ordered
from the factory as an optional accessory. Dimensions listed are that of the inner coil area in the
plenum. For larger coils, field provisions to the factory built plenums are necessary or one will
need to be custom built by the installer. (In heat pump applications, the indoor coil MUST be
placed on the return air side.)
