PARTS OF YOUR HEATER

Product Parts

STEP 1 Locate or route electrical supply wires

  • For best results, install your baseboard heater under a window, along an outside wall, or as close as possible to an outside door.
  • Install only in a horizontal position, not in a vertical position.
  • Remove any floor base trim or molding so the heater will set flush against the wall. It can sit directly on any floor surface, including carpet.
  • If you’re wiring a WALL thermostat, route the electrical supply wire from the circuit breaker to the wall thermostat, and then to the heater. If you’re wiring a BUILT-IN model or TBTK thermostat, route the electrical supply wire from the circuit breaker directly to the heater.
    1A. Turn off the electrical power supply. Locate wall studs and electrical supply wires. DON’T CUT ANY FACTORY CONNECTIONS UNTIL YOU’RE READY TO WIRE!
    Locate Instructions
    1B. Remove only the wiring compartment cover. Wire connections can be made on either side of the baseboard heater.
    Locate Instructions
    1C. Remove one of the slotted knockouts in the wiring compartment.
    CONNECTIONS INSTRUCTIONS

    INSTALLATION INSTRUCTIONS
  • 2B. Mount the heater securely to two or three wall studs.
    INSTALLATION INSTRUCTIONS

STEP 3 Baseboard Wiring

  • KNOW YOUR VOLTAGE and CHECK YOUR BREAKER!
  • All baseboard heaters require three supply wires. For 240 and 208 volt baseboard wiring you will have 2 hots and 1 ground; no neutral needed.
  • Cut ONLY ONE factory connection and ONLY on the side you will be wiring!

LEFT SIDE WIRING

  • If you’re wiring on the left side, CUT ONLY THE ONE FACTORY CONNECTION SHOWN.
    INSTALLATION INSTRUCTIONS

RIGHT SIDE WIRING

  • If you’re wiring on the right side, CUT ONLY THE FACTORY CONNECTION ON THIS SIDE.

OPERATING INSTRUCTIONS

  1. Make sure all wires are properly connected and installation is complete before you turn on the heater.
  2. Turn the heater to the highest setting and allow it to run for 30 minutes.
    Some smoking may occur as the element initially burns off residue from manufacturing.
  3. If your heater shows signs of overheating, such as glowing red or repeatedly getting unusually hot and shutting off, immediately turn off the circuit breaker and review the “Know Your Voltage” section or call us.
  4. Do not tamper with the high temperature safety shutoff.

How to operate your heater

The room temperature is controlled by a thermostat located either on the wall, or on the heater. Once installation is complete and power has been restored, follow the steps below for your thermostat.

If you have a mechanical wall or built-in thermostat:

  1. Turn the thermostat knob all the way to the right.
  2. When the room reaches a comfortable temperature, turn the knob to the left, just until it clicks and the heater turns off. The heater will automatically keep the room at this setting.
  3. To reduce the room temperature, turn the knob to the left. To increase the room temperature, turn the knob to the right.
    If you have an electronic thermostat, follow the instructions in the programming and operating guide included with your thermostat.

PLEASE NOTE: On initial start-up, the heater may cause an odor due to the manufacturing process. It typically goes away within several hours. High-temperature safety shutoff
All baseboard heaters come with a built-in high-temperature safety shutoff that stops electricity flowing to the heater if it gets too hot inside. This automatically resets after cooling.
