Hydronic Kickspace Heaters

Beacon/Morris
TWIN-FLO III heaters are for use with forced hot water residential heating systems and consist of a copper tube, aluminum finned
heating element, with an electric motor and blower of unique cross flow design. Their purpose is to deliver a comfortable stream
of warmed air, at or near floor level, and their construction is extremely compact so minimum space is required for installation.
The type K heater is primarily used in horizonal floor installation, for example: under a kitchen counter cabinet, or bathroom sink
enclosure. They are ideal for radiant systems with the use of a low temperature aquastat designed to turn the unit on at 110°F. Type
W is for vertical mounting, fully recessed in the wall studs, with the air discharged upward through a flush mounted, louvered front
panel. Type F is a surface mounted wall unit, with the air discharged evenly through a louvered front panel in an upward direction.
All types have heating elements with 1/2" nominal (5/8 O.D.) copper tube connections, and 115V. electric blower motor, interwired
with a 120°F (49°C) reverse acting aquastat that prevents operation until hot water is circulating. These units are NOT intended to
be used on one or two pipe steam systems. For gravity fed systems, it is recommended that a separate circulator pump be installed
for the kickspace heater.
