TO TURN OFF THE WATER HEATER
1. Turn off the power supply to the water heater at the isolation switch.
EMERGENCY SHUT-DOWN
1. Turn off the power supply to the water heater at the isolation switch.
2. Turn off the gas isolation valve at the inlet to the water heater or the main gas supply.
CHECK FOR NORMAL OPERATION
•
With the water heater operating, remove the door and make a visual check of the burners. The
flame should be blue with a well-defined pattern.
•
A yellow or floating flame indicates restricted air openings, incorrect gas type, incorrect orifice size
or possible excessive draught.
•
Observe for any indication of soot. The presence of soot accumulation would indicate an abnormal
operating condition.
Should abnormalities be observed, turn off the water heater and contact Rheem Service or your
nearest Accredited Service Agent.
Operation of the water heater due to poor combustion will result in rapid and severe
damage, which is not covered by warranty.
