Maintenance Continued-
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 section
on page 19.
5. Annually remove the inner door and main burner 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 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.
6. At least once a year, check the combination temperature and pressure relief
valve to insure that the valve has not become encrusted with lime. Lift the
lever at the lever at the top of the valve several times until the valve seats
properly without leaking and operates freely.
7. Monthly drain off a gallon of water to remove silt and sediment.
8. If the combination temperature and pressure relief valve on the appliance
discharges periodically, this may be due to thermal expansion in a closed
water supply system. Contact the water supplier or local plumbing
inspector on how to correct this situation. Do not plug the combination
temperature and pressure relief valve outlet.
9. A combination sacrificial anode rod/hot water outlet nipple has been
installed to extend tank life. The anode rod should be inspected
periodically and replaced when necessary to prolong tank life. Water
conditions in your area will influence the time interval for inspection and
replacement of the anode rod. Contact the plumbing professional
WARNING
The ventilation air system may be HOT.
WARNING
When lifting lever of the combination temperature and pressure relief valve,
hot water will be released under pressure. Be careful that any released water
does not result in bodily injury or property damage.
WARNING! THIS WATER MAY BE HOT.
