About the Marley WH4407FCNW
The Marley WH4407FCNW is a fan-forced electric wall heater from the WH Architectural Heavy-Duty series, made for comfort heating indoors. It is rated 4000 watts on 277-volt single-phase power and 3000 watts on 240 volts. It ships wired for full output and can be converted in the field to half output (2000 watts at 277 volts or 1500 watts at 240 volts). This is the NW version of the heater.
The heating element is switched on and off by a built-in thermostat, and a fan-delay control keeps the fan going for a short time after the element shuts off to clear leftover heat. Warm air leaves through openings along the bottom of the grille. The assembly also includes a manual-reset overheat limit, with a red reset button you can see through the grille, and a power on/off disconnect switch.
The heater recesses into a wall-mounted back box and is meant for indoor wall installation only, blowing air downward. It should not go in ceilings or floors, or in damp or wet locations. It conforms to ANSI/UL 2021 and CSA C22.2 No. 46.
Installation Tips
Turn off power at the breaker before working on the heater, and have a qualified electrician make the connections. In new construction, the back box mounts between two wall studs on 16-inch centers; in an existing wall, cut an opening 14-1/2 in. wide by 18-1/2 in. high. Keep the heater at least 8 in. above the floor and 8 in. from adjacent side walls; at least 36 in. to the ceiling is recommended. Do not connect a remote thermostat, and do not wire the unit in a way that bypasses the fan-delay off feature.
To switch to half wattage, reposition the red jumper that links the upper and lower element terminals, then write the new wattage on the label in the back box.
