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 
on page 36. 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. 

Water heaters are heat producing appliances.  To avoid damage or injury there 
must be no materials stored against the water heater or vent-air intake 
system, and proper care must be taken to avoid unnecessary contact 
(especially by children) with the water heater and vent-air intake system.  
UNDER NO CIRCUMSTANCES MUST FLAMMABLE MATERIALS, SUCH 
AS GASOLINE OR PAINT THINNER BE USED OR STORED IN THE 
VICINITY OF THIS WATER HEATER, VENT-AIR INTAKE SYSTEM OR IN 
ANY LOCATION FROM WHICH FUMES COULD REACH THE WATER 
HEATER OR VENT-AIR INTAKE SYSTEM.
