About the Marley 548A
The Marley 548A is the heater section of a fan-forced electric ceiling heater: the heating elements, fan and controls in one assembly. It is built for ceiling installation only and needs a separate surface-mount or recessed mounting enclosure to complete the installation. The recessed enclosure fits a standard 2 ft x 2 ft T-bar ceiling.
It is rated 4 kW at 208V, and the output can be reduced in the field to 4, 3 or 2 kW by removing jumper wires. It can be wired for single- or three-phase power; it leaves the factory set up for single phase. Adjustable discharge grilles let you choose a narrow, wide or asymmetrical air pattern, and the fan keeps running for about a minute after the elements shut off.
A wall thermostat, relays and a disconnect switch are offered as options. The heater should not be used in corrosive atmospheres or where flammable liquids are stored.
Installation Tips
Turn off power at the breaker before working on the heater. The mounting must support 45 lb, field wiring must be #10 AWG minimum rated for 90°C, and the heater must be at least 12 in. (305 mm) from walls. Don't wire an external thermostat so that it cuts power to the fan.
