MAINTENANCE
The following maintenance should be performed by a qualified service
technician at the minimum periodic intervals suggested below. In some
installations, the maintenance interval may be more frequent depending on the
amount of use and the operating conditions of the water heater. Regular
inspection and maintenance of the water heater and vent-air intake system will
help to insure safe and reliable operation.
1. Annually check the operation of the thermostat.
2. The flow of combustion and ventilation air MUST NOT be restricted. Clear
the combustion air openings of any dirt, dust, or other restrictions.
3. At all times keep the water heater area clear and free from combustible
materials, gasoline and other flammable vapors and liquids.
4. Bi-annually conduct a visual check of the main and pilot burner flames to
determine that they are burning properly. See the Burner Flame Check
section for illustration. If sooting or other burner anomalies are evident, shut
down the water heater by turning off the gas per the instructions listed in
this manual or as listed on the water heater.
