Maintenance continued-
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.
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.
Do not run out of propane gas. Damage to the water heater may occur.
6. At least once a year, check the combination temperature and pressure relief valve
to ensure 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.
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.
A combination sacrificial anode rod/hot water outlet nipple has been installed to extend
tank life. The anode rod 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 the 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 anode is needed when
using softened (or phosphate treated) water.
FOR YOUR SAFETY, DO NOT ATTEMPT REPAIR OF COMBINATION 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.
READ THE WARRANTY FOR A FULL EXPLANATION OF THE LENGTH OF
TIME THAT PARTS AND THE WATER HEATER ARE WARRANTED.
