SCHEDULED MAINTENANCE AND SERVICING
WARNING / CAUTION
Before performing any maintenance procedure, turn off the water heater main disconnect switch
before performing any cleaning or service. Also close both the pilot and main manual shutoff valves.
Keep the equipment room clean. Clean the burner at regular intervals. The blower inlet can collect
dust and debris from the air during operation. Clean blower wheel and flame scanner when
necessary. The burner should be cleaned each year according to the burner manufacturer's
recommended procedures. A DIRTY BLOWER WHEEL WILL REDUCE EFFICIENCY AND
MAY CAUSE POOR COMBUSTION, SOOTING OR THE PRODUCTION OF CARBON
MONOXIDE.
IMPORTANT
A preventive maintenance program should be established to help assure a long, trouble-free water
heater life. AN ANNUAL INSPECTION SHOULD BE PERFORMED AND DOCUMENTED.
A COPY OF THE INSPECTION REPORT MUST BE FORWARDED TO THE
MANUFACTURER. FAILURE TO DO SO WILL VOID THE WARRANTY.
