KNOW YOUR VOLTAGE!

TOOLS REQUIRED OR YOU MAY NEED

When using electrical appliances, basic precautions should always 

be followed to reduce the risk of fire, electric shock, and injury to 

persons, including the following:

240 volt

Double-pole 

breaker

•  CHECK YOUR BREAKER! If you’re replacing an existing heater, 

check the labels of the old heater and use the same voltage. 

•  Connecting a 240 volt heater to a 120 volt electrical supply will 

only give you 25 percent of the wattage!

•  The most important thing you need to do is verify the electrical 

supply wires you’re using are the same voltage as the heater. 

STEP 1

Locate or route electrical supply wires

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!   

1B.  Remove only the wiring compartment 

cover. Wire connections can be made on 

either side of the baseboard heater.

1C.  Remove one of the slotted knockouts in 

the wiring compartment.

2A.  Connect the grounding lead to the green 

grounding screw on the side you’re wiring.

2B.  Mount the heater securely to two or 

three wall studs.

1D.  Install a cable clamp connector (not 

included). Pull supply wires through the 

cable clamp connector leaving 6-inch 

wire leads.

• 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.

•  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!

•  If you’re wiring on the left side, 

CUT ONLY THE

.

•   If you’re wiring on the right side,

 CUT ONLY THE 

FACTORY CONNECTION ON THIS SIDE

.

3A.  Connect one supply wire to one of the heater 

wires with a wire connector (not included). 

•   For 240 and 208 volts, it doesn’t matter which 

heater wire (Figures 7b or 8b). Wrap supply 

(white) wire with black tape to identify it as hot. 

3B.  Connect remaining supply wire to remaining 

heater wire with a wire connector (not included).

NOTE: All baseboard heaters require a thermostat (sold separately). Electric heaters 

must be installed on a circuit dedicated to electric heaters, they cannot share a circuit 

with outlets, lights, or other appliances. A double-pole thermostat has an OFF setting. 

A single-pole thermostat does not.

WARNING: Make sure power to the heater is turned off at the main disconnect panel 

whenever doing any work on a heater. Serious injury or electrocution can result from 

electric shock. Connecting a heater to a voltage higher than what’s listed on its rating 

label will destroy the heater and could start a fire. A heater will not heat properly 

when connected to a voltage lower than what’s listed on its rating label. If you are 

uncomfortable working with electricity, running electrical supply wire or installing a 

circuit breaker, please consult a licensed electrician.

How to operate your heater 

The room temperatur

e is controlled by a thermostat located either on the wall, or on the heater

. Once 

installation is complete and power has been restor

ed, follow the steps below for your thermostat. 

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

1. T

urn the thermostat knob all the way to the right.

2. When the r

oom reaches a comfortable temperatur

e, turn the knob to the left, just until it clicks and 

the heater turns of

f. The heater will automatically keep the room at this setting.

3. T

o reduce the r

oom temperature, tur

n the knob to the left. To incr

ease the room temperatur

e, turn 

the knob to the right. 

If you have an electronic thermostat, follow the instructions in the pr

ogramming 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.
