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.
WARNING! The ventilation air system may be HOT.
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.
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. NOTE: It is imperative for proper operation of the water
heater that the inner door be replaced in the original location.
