Selecting a location for your heater:
Do NOT install less than 6 inches from vertical side walls or open edge of the door. The heater must have unrestricted airflow. Do Not select a location where it is likely to be blocked by furniture, curtains, etc. Be sure the location selected allows sufficient space for the heater as shown below in Table 1. Do NOT locate the heater in areas where combustible vapors, gases, flammable liquids, or excessive lint, dust or moisture is present.
Zero clearance to insulation

The wire & breaker sizing chart will give a general rule of installation size. Consult an electrician if not knowledgeable about wiring codes.
Wire and Breaker Sizing:
WIRING : Branch Circuit Connection
- Connect the heater only to the voltage, amperage and frequency specified on the nameplate.
- Remove the grill by loosening and removing the four screws on the side of the front panel.
- Detach the interior from the wall can by removing the four screws along each side of the interior. Remove the interior by tilting it away from the wall can to release the bottom edge.
- Wiring procedures and connections shall be by all National and local codes having jurisdiction.
- A knockout of 1/2 inch conduit size (7/8 inch) is provided in the back and side of the heater for power to enter. Provide proper strain relief connectors (not included) for your wire entering the wall box.
- Install a wall box a minimum of 6″ from vertical side walls & 4″ above the floor (For best performance 10″ above the floor is recommended).
- Secure the wall box to the 2 x 4 studs using the (2) holes on the side of the wall box. Secure to a wall stud on the opposite side if required. Make electrical connections per the wiring diagram. Supply wires L1 and L2 can be connected to the red or black wires on the heater – the order does not matter. Attach the field ground wire to the green screw or pigtail. When installing a built-in thermostat red always connects to the supply wires and black to the heater.
- Reinstall interior. Make sure electrical wires are clear on the interior sides. Fasten the interior and then the grill with the screws provided.
- Test the unit by turning the thermostat up past room temperature. You will see a puff of smoke as the elements are energized and the fan turns on. This is a normal burn-off of manufacturing lubricants and will dissipate in 5 minutes.
- The heater will continue to run until the room temperature you set is reached and then turn itself off until the temperature drops again.
INSTALLATION AND WIRING
SMART LIMIT PROTECTION AND MAINTENANCE
Heater Safety Limit Tripped?
This heater is equipped with a thermal overload Smart Limit Protection which
disconnects elements and motor in the event normal operating temperatures are
exceeded. If thermal overload trips due to abnormal
operating temperatures, thermal overload shall remain open until manually
reset by turning the heater OFF for fifteen minutes. Inspect for any objects
on or adjacent to the heater that may cause high temperatures.
After inspecting the heater, keep the power to the heater off for 15 minutes
to reset the SLP thermal protector. If the SLP thermal protector shuts the
heater off again, immediately turn the heater OFF at the circuit breaker and
inspect the heater for possible fan motor failure or dirt and lint on the
heating element. Repeat the starting procedure.
