ALWAYS REMOVE THE POWER CORD FROM ITS RECEPTACLE
BEFORE SERVICING THE HEATER.
IF THE HEATER STOPS WORKING:
1. Check the circuit breaker supplying power to the outlet where the
heater is installed. If the breaker has tripped, have the circuit
checked by an electrician to determine if the circuit is overloaded,
or if a short exists.
2. If the circuit breaker has not tripped, remove the power cord from
its receptacle, remove the thermostat cover on the front of the
heater, inspect the heater for any frayed or loose electrical
connections, and push the red "reset" button at the top of the
thermostat compartment. If the button "clicks" when pushed,
something has caused the heater to overheat. Leave power cord
unplugged and contact your service agency.
3. If the button does not "click" when pushed, the element has
probably burned out and should be replaced. Contact your service
agency.

THE RELIEF VALVE:
