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
upon 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.
Annually inspect the direct vent-air intake terminal to insure it is not
blocked or damaged. Clear the direct vent-air intake terminal openings
of any dirt, dust, or other restrictions. WARNING! Certain areas of the
direct vent-air intake terminal are HOT.
3. Annually inspect the vent-air intake system to insure that all components
are securely fastened and all joints and seams are properly sealed.
4. At all times keep the water heater area clear and free from combustible
materials, gasoline and other flammable vapors and liquids.
5. Bi-annually conduct a visual check of the main and pilot burner flames to
determine that they are burning properly. See “BURNER FLAME
CHECKS.”
