About the Marley K304FC

The Marley K304FC is a complete K Series fan-forced wall heater rated at 3000 watts on a 240-volt, single-phase supply. It draws 12.5 amps and moves about 100 CFM of air.

The factory manual says not to use the K Series outdoors. Keep it out of damp or wet areas, away from corrosive chemicals, and away from any place where gasoline, paint or other flammable liquids are kept or used. Leave at least 3 feet of clearance between the heater front and furniture, bedding or curtains, and keep the air intake and outlet clear.

Replacement parts for this heater include the 410074000 fan delay and the 3900-2010-000 208/240V motor.
