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.” 

 

Water heaters are heat producing appliances.  To avoid damage or 
injury, do not store materials against the water heater or vent-air intake 
system.  Use proper care 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
