Troubleshooting guide

To remove the burner rack assembly, follow the procedure outlined below:
a) Shut off the gas and electrical supply to the water heater.
b) Remove the pilot tube fittings at the gas valve and combustion box.
c) Disconnect wires to gas valve. Open control box and disconnect pilot spark and flame sensor wires. Remove the
wire raceway cover below the control box.
d) Disconnect the gas pipe union below the gas valve.
e) Remove the three screws securing the gasketed manifold pipe flange on the left side of the combustion box.
f) Remove the burner access panel from the front of the combustion box.
g) Carefully remove and push the pilot wire grommet into the combustion box with the pilot wires.
h) Disconnect the pilot tube fitting on the inside bulkhead fitting of the combustion box.
I) Un-thread the gas pipe assembly from the manifold inside the combustion box.
j) Remove the screw securing the burner rack on the top right panel of the combustion box.
k) Slide out the burner rack assembly.
To reinstall the burner rack, reverse the above procedure.
9. 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.
10. Monthly drain off a gallon of water to remove silt and sediment.
11. 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.
12. All models are equipped with a cleanout opening to aid in removal of hard water deposits from the tank bottom. If
this water heater operates under hard water conditions, the following should be performed at least every 3 months:
Drain the water heater. Remove the cleanout jacket cover and tank cover. When cleaning the tank, care must be
taken to avoid trying to break deposits loose as this could damage the glass lining and shorten the life of the water
heater. After cleaning, replace the cleanout tank cover and jacket cover, and refill with water. Refer to filling and
draining the water heater.
13. Four sacrificial anode rods have been installed in the tank head to extend tank life. The anode rods should be
inspected annually for corrosion 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. 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. Contact the plumbing professional who installed the water heater or the manufacturer
listed on the rating plate for anode replacement information.
14. Oil the induced draft blower motor in the ports of the front and rear motor bearings every 6 months with 4 drops each
of SAE 20 motor oil.
15. The vent system must be inspected at least once a year to ensure against leakage of exhaust products.
THIS WATER 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.
Keep clear of the combination temperature and pressure relief valve discharge line outlet. The discharge
may be hot enough to cause scald injury. The water is under pressure and may splash.
WARNING
FOR YOUR SAFETY, DO NOT ATTEMPT REPAIR OF COMBINATION GAS CONTROL, BURNERS OR GAS
PIPING. REFER REPAIRS TO A QUALIFIED SERVICE TECHNICIAN.
