To Shut Down

Move the mode switch to "OFF". The exhaust

blower will still run until the heater cools down.

NOTE: When you press the Fan speed

buttons the “Heat Output” lights will

indicate fan speed (not “Heat Output”).

After a few seconds the “Heat Output”

lights will go back to displaying the heat

output setting.
