WARNING! Before removing grill, turn the electrical power off at the electrical panel board (circuit breaker or fuse box). Lock or tag the panel board door to prevent someone from accidentally turning the power on while you are working on the heater. Failure to do so could result in serious electrical shock, burns, or possible death.

1. Turn the heater switch to on. If the heater turns on, you have turned off the wrong circuit breaker at the electrical panel board.
2. If heater does not turn on, proceed with next step.
3. Remove screws and take off grill.
