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.
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.
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 top of the valve several
times until the valve seats properly without leaking and operates
freely.
Warning
Do not allow the water heater to run out of propane.
7. Monthly drain off a gallon of water to remove silt and
sediment.
Warning
This water may be hot.
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. Combination sacrificial anode rods have been installed to
extend tank life. These anode rods should be inspected
periodically (every 2 years) and replaced when necessary to
prolong tank life. Water conditions in your area will influence the
time interval for inspection and replacement of an anode rod.
Contact the plumbing professional who installed the water
heater or the manufacturer listed on the rating plate for anode
replacement information. The use of a water softener may
increase the speed of anode consumption. More frequent
inspection of the anodes are needed when using softened (or
phosphate treated) water.
10. The blower has sealed motor bearings and does not require
adding oil.
FOR YOUR SAFETY, DO NOT ATTEMPT REPAIR OF GAS
CONTROL, BURNERS OR GAS PIPING. REFER REPAIRS TO
A QUALIFIED SERVICE TECHNICIAN.
Contact your supplier or plumbing professional for replacement
parts or contact the company at the address given on the rating
plate of the water heater.
Provide the part name, model and serial numbers of the water
heater when ordering parts.
