SECTION X: MAINTENANCE
1. A qualified service technician should perform the following maintenance 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 will help to
insure safe and reliable operation.
2. Annual checks of the ignition systems, temperature controls and any other water heater controls are necessary to
ensure proper operation. Also, all safety shut-off valves must be checked to verify proper operation and tightness.
3. The entire combustion system must be sealed for this water heater to function properly. Make sure the burner
access panel is kept tightly sealed. The combustion air supply pipe at the rear of the water heater must be tightly
clamped to the vent adapter and combustion air box boot. Replace any damaged parts. The entire venting system
and combustion air supply parts must be inspected at least annually for integrity of all joints and gaskets.
4. The flow of combustion and ventilation air MUST NOT be restricted. Keep the direct vent terminal openings clear of
objects, shrubs, snow, and debris. Check to make sure the vent terminal is not damaged.
5. At all times keep the water heater area clear and free from combustible materials, gasoline and other flammable
vapors and liquids.
6. Annually conduct a visual check of the pilot and burner flames to determine that they are burning properly. See
“Burner Flame Check” section for an illustration of the proper burner flame pattern.
7. At annual intervals check the flue baffles for deterioration and scale or carbon deposits. Clean if necessary and
brush the flue tubes if excessive scale or deposits are found on the baffles. Replace any baffles that have become
excessively warped or deteriorated. Check the flue collector gasket for integrity and replace if necessary. Cleaning
of the flue baffles and flue tubes should be done prior to cleaning the burners, since deposits may fall on the burners
during cleaning or checking the baffles.
8. Annually remove the main burner rack 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, vacuum, or use a mild
detergent solution to clean as needed. Inspect the pilot. Carefully clean the electrode and flame sensor rod with
emery cloth. The spark electrode (rod closest to the pilot hood) gap should be 1/8”.
WARNING
Do not run out of propane gas. Damage to the water heater may occur.
The water heater should be inspected at a minimum annually by a qualified service technician for damaged
venting system components and/or vent and combustion air supply joints not sealed. DO NOT operate this
water heater if any part is found damaged or if any joint is found not sealed.
NOTICE
The ventilation air system may be HOT.
WARNING
It is imperative for proper operation of the water heater that the main burner rack be replaced in the original location.
