Commercial Performance

Rated for 240/208 volts, this heater easily handles moderately sized working commercial spaces. Depending on the wattage, you can heat up garages, hangars, warehouses, or shipping rooms between 250-500 square feet.

• 240 Volts: Uses 5,000-3,333 watts and 21-14 amps.
• 208 Volts: Uses 3,700-2,500 watts and 18-12 amps.

The internal heating element is encased in a copper steel sheathing that takes less time to heat while providing quick dispersal of heat. Made with a heavy gauge die-formed steel housing, the enclosed motor fan is protected against dust, large particulates, and debris.

Continuous or Cycling Heat

Warm work environments between 40-90 degrees F with the variable thermostat, 2 heat settings and a fan only option.

• Continuous Heating: Turn the variable thermostat knob clockwise for continuous heating.
• Cycling Heat: After warming up the room, turn the knob counterclockwise slowly to set the heater to turn off and on to maintain a set temperature.
• Fan Only: Use the fan only option when air circulation is needed.

Additional Features

• Overheat Protection: To further protect the copper steel sheathed heating element, the overheat protection keeps the heater from overheating and straining the heating element.
• Overheat Alarm: When the overheat protection is triggered, the overheat alarm will sound.
• Fan Delay: To prevent blowing cold air, the fan delays circulation until the heating element is warm.
• Long Warranty: Backed by the QMark guarantee, this heater features a 5-year limited warranty on the heating element and 1-year limited on parts and labor.
