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 Burner Flame Check

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.
