Marley LFK4083 Fan Forced Wall Heater 4000W 208V

Product Description

The MARLEY LFK4083 is a fan forced wall heater rated at 4,000 watts and 208 volts, delivering up to 13,650 BTU/h of supplemental or primary space heating. Drawing 11.1 amps, it circulates air at 100 CFM through a compact cabinet measuring 15.75 inches wide, 1.375 inches deep, and 19.125 inches high. The fan forced design pushes heated air directly into the space, providing faster temperature recovery than convection-only units. Licensed electricians and HVAC technicians install this heater in commercial and light industrial applications where 208-volt service is available. At 22 pounds, the unit is manageable for a one- or two-person installation crew.

The LFK4083 is suited for installations in commercial offices, retail spaces, workshops, and utility areas served by 208-volt single-phase electrical systems. Its wall-recessed or surface-mount profile keeps floor space clear, making it practical in tight mechanical rooms, entryways, or supplemental heating zones. The 100 CFM fan output is sufficient for consistent heat distribution in small to mid-size rooms. This heater is intended for permanent wired installation and is not a plug-in unit.

Key Features

Compatibility

Designed as an OEM-style fan forced wall heater for 208-volt single-phase electrical systems in commercial and light industrial heating applications.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Disconnect and lock out power at the panel before beginning any wiring work. This unit requires a dedicated 208-volt circuit sized to handle the 11.1-amp continuous load with appropriate overcurrent protection. Do not install in locations exposed to water, flammable vapors, or environments requiring a listed explosion-proof fixture.
