Maintenance continued-
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. Make sure
slots in jacket are open and unobstructed. Clear jacket slot 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 Burner Flame Check section of this
installation and operation manual. 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.
5. Annually remove the inner door and main burner assembly to clean orifices and
related parts of any dirt or other foreign material. Inspect the burner ports for
obstructions or debris and clean with a wire brush as needed. Wire brush and/or
vacuum clean the combustion chamber as needed to remove scale deposits and
debris.
