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 wall or built-in thermostat:
1. Turn the thermostat knob all the way to the right.
2. When the room reaches your comfort level, turn the knob to the left, just until it clicks and
the heater turns off. The heater will automatically keep the room temperature around 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 wall 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 Register heaters come with a built-in high-temperature safety shutoff that stops electricity flowing to
the heater if it gets too hot inside. See TROUBLESHOOTING on Page 8 if you’re experiencing prob-
lems with your heater.
