BASEBOARD HEATER
INSTALLATION GUIDE
ATTENTION: Before attempting to install your heater, verify that the power
supply wires are the same voltage as the heater you are installing. The best
way to check for proper voltage is by using a voltmeter, testing between
supply line 1 and 2. 240 and 120 Volt heaters are not interchangeable.
Connecting a 240 Volt heater to a 120 Volt circuit will reduce the wattage
75% making the heater feel barely warm. Connecting a 120 Volt heater to
a 240 Volt circuit will destroy the heater, could cause fi re damage, personal
injury or death, and, voids all warranties.
WARNING: Turn off power source to the heater before attempting installation, maintenance or repairs. Lock, tape or tag circuit breaker or fuse so
that power cannot be turned on by accident. Failure to do so could result in
serious electrical shock, burns or possible death.
PLACEMENT: When possible baseboard heaters should be placed on an
outside perimeter wall under a window. This is due to the fact that the outside wall is usually the spot of greatest heat loss. A baseboard heater may
sit directly on any fl oor surface including carpet. Do not allow carpet to block
air intake at bottom.
GENERAL SAFETY INFORMATION: Keep electrical cords, any bulky furniture or other household items that could restrict airfl ow away from heater.
Refer to clearance diagram for drapes. Do not install heater below an electrical outlet or against vinyl wallpaper, paperboard or low density fi berboard
surfaces. Do not recess mount heater. Do not mount heater vertically. Do not
store fl ammable liquids in vicinity of the heater. Installation must comply with
applicable national and local electrical codes. Protect electrical supply wire
from nicks, sharp objects, oil, grease or other chemicals that could damage
the insulation.
INSTALLATION INSTRUCTIONS:
1. Make sure heater is positioned on the wall with the “Bottom” label facing
the fl oor. Mounting upside down could be a hazard.
2. Remove junction box cover from left or right end. The heater can be
wired from either end.
3. Remove knockout and pull supply wires through. Use a cable fi tting to
secure the power wires.
4. Locate wall studs and secure heater to wall with a nail or screw. Use the
mounting dimples in the back can to position the fastener. The dimples
will prevent the fastener from slipping when applying pressure to pierce
the metal back can. You do not have to remove the cover or refl ector to
mount the heater.
5. Connect electrical wires and groundwire to the heater per the appropri ate wiring diagram on following pages.

Instructions for Left or Right Side Wiring Connection
1. Caution: Do not cut both factory splice caps
on left side! You need only two wires for power
connection.
2. Heater can be wired from either side - wire one
side only.
3. Cut only one factory splice cap or loop wire as
shown.
4. This leaves two wires for power connection.

1. Connect power supply wires from wall
thermostat as shown.
2. Black and white supply wires can be connected
to the heater in reverse order. For simplicity the
most common method is shown.
