Testing the GFCI Monthly
Test your GFCI protection monthly to ensure proper operation:
- Verify the trip indicator light is off (if on, press Reset)
- Turn the heater to maximum temperature and wait 10 minutes
- Press the Test button
- Verify the trip indicator illuminates
- Wait 5–10 minutes to confirm the floor heater cools
- Press the Reset button to end the test
