The Beacon Morris K84 Twin-Flo III is a Kickspace Heater with 3370-10360 BTU/Hr range that saves space and is an alternate to hot water baseboards. It's a small device designed to install in inconspicuous areas. This Kickspace Heater (type K) is primarily used in horizonal floor installation.

The Twin-Flo III is available in three different models. Model K42, Model K84 and Model K120. They differ in size, dimensions and power. The Beacon Morris K42 is the smallest design. This model is ideal to fit under cabinets. The next biggest model, Model K84 is slightly bigger and good for kitchens, baths and foyers. The biggest and most powerful model is the K120. This model is suited to fit under stair risers and windows.

Sealed, triple ball bearing construction provides protection for the motor and fan. This allows years of quiet and reliable service.

Beacon Morris Kickspace Heaters work with the home's hot-water heating system to keep hard to heat areas warm and comfortable. You don't need a boiler to stay warm. Twin-Flo III units can provide spot heat using the domestic hot water heater as a source of heat.

The Beacon Morris K84 has heating elements with 1/2" nominal copper tube connections. Its 115V electric blower motor interwired with a 120F reverse acting aquastat that prevents operation until hot water is circulating. Optional low temperature aquastat available for low temperature applications. Standard Aquastat Range 120 - 105 F; Low Temp Aquastat Range 110 - 95 F.



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 kick space heater.
