It’s very important to set your clock on your Toyo heater after a power outage.
When the heater is on and clock is set, it will automatically stop and clean the igniter every day at 2:00 AM and will display “CL” on the Display. After the cleaning mode is finished the heater will automatically re-ignite and continue to burn again.
The igniter cleaning mode helps prolong the igniter life.
