- Use copper conductors only.
- Use only on series F baseboard heaters.
- Turn off power to heater at main disconnect panel.
- Connect grounding lead to grounding screw provided on the heater.
- Use wire connectors (not included) for all connections.
TIPS BEFORE YOU BEGIN
- Verify power has been turned off before starting any work!
- Follow the instructions in your Baseboard Owner’s Guide (included with your heater) until prompted to make thermostat connections.
- IMPORTANT: If wiring on the left side, cut ONLY ONE factory connection and ONLY on theside you will be wiring! If your baseboard is a 120 volt model, cut ONLY the factory connection that has one black and one white wire!

MULTIPLE BASEBOARDS WITH ONE THERMOSTAT
Multiple baseboards can be wired in parallel on the same circuit (check national and local codes for safety requirements). Additional electrical supply wire and cable clamp connectors are required. The heaters must be in the same room. The maximum amperage load you can put on one circuit breaker is limited to either 80% of the circuit breaker capacity, or the maximum amperage rating of the thermostat, whichever is lower. Cut one factory connection on each baseboard on the side you will be wiring. Two sets of electrical supply wire go through two cable clamp connectors of baseboard #1. One set of wires goes to the power supply and the other set goes to baseboard #2. There are two supply ground wires. You’ll need another short piece of copper wire to make the 3-wire connection with the ground screw in baseboard #1.
BTF1
- A. Connect one supply wire to the red thermostat wire.
- B. Connect the black thermostat wire to one wire from each heater.
- C. Connect the remaining wire from each heater to the remaining supply wire.
- D. Make a 3-wire connection with the two supply ground wires and the ground screw in heater #1.
For 240 or 208 volt, both black and white supply wires are hot. Wrap supply (white) wires with black tape to identify them as hot! See Baseboard Owner’s Guide for baseboard #2 connections.
BTF2
- A. Connect each of the two supply wires coming directly from the power supply, to each of the red thermostat wires.
- B. Connect one black thermostat wire to one wire from each heater.
- C. Connect the remaining black thermostat wire to the remaining wire from each heater.
- D. Make a 3-wire connection with the two supply ground wires and the ground screw in heater #1.For 240 or 208 volt, both black and white supply wires are hot. Wrap supply (white) wires with black tape to identify them as hot! See Baseboard Owner’s Guide for baseboard #2 connections.
Tuck all the wires back into the individual wiring compartments, and make sure
the connections are tight. Attach with small screw at bottom.
Proceed to OPERATING INSTRUCTIONS.
OPERATING INSTRUCTIONS
Make sure all wires are properly connected and installation is complete before
you turn on the heater.
Turn power back on at the main disconnect panel.
- Turn the thermostat knob all the way to the right. For tamper proof models, remove small plastic plug first, then turn the thermostat shaft all the way to the right.
- When the room reaches your comfort level, turn the knob/shaft to the left, just until it clicks and the heater turns off. The heater will automatically keep the room temperature at this setting.
- To reduce the room temperature, turn the knob to the left. To increase the room temperature, turn the knob to the right.
