SERVICE
If a condition persists or you are uncertain about the operation of
the water heater contact a service agency.
Use this guide to check a “Leaking” water heater. Many suspected
“Leakers” are not leaking tanks. Often the source of the water can
be found and corrected.
If you are not thoroughly familiar with gas codes, your water heater,
and safety practices, contact your gas supplier or qualifi ed installer
to check the water heater.
LEAKAGE CHECKPOINTS
Read this manual fi rst. Then before checking the water heater make
sure the gas supply has been turned “OFF”, and never turn the gas
“ON” before the tank is completely full of water.
A. *Condensation may be seen on pipes in humid weather or pipe
connections may be leaking.
B. *The anode rod fi tting may be leaking.
C. Small amounts of water from temperature-pressure relief valve
may be due to thermal expansion or high water pressure in your
area.
D. *The temperature-pressure relief valve may be leaking at the
tank fi tting.
E. Water from a drain valve may be due to the valve being slightly
opened.
F. *The drain valve may be leaking at the tank fi tting.
G. Combustion products contain water vapor which can condense
on the cooler surfaces of the tank. Droplets form and drip onto
the burner or run on the fl oor. This is common at the time of
start-up after installation and when incoming water is cold.
H. Water in the water heater bottom or on the fl oor may be from
condensation, loose connections, or the relief valve. DO NOT
replace the water heater until a full inspection of all possible water
sources is made and necessary corrective steps taken.
Leakage from other appliances, water lines, or ground seepage
should also be checked.
* To check where threaded portion enters tank, insert cotton
swab between jacket opening and fi tting. If cotton is wet, follow
“Draining” instructions in the “Periodic Maintenance” section and
then remove fi tting. Put pipe dope or tefl on tape on the threads
and replace. Then follow “Filling the Water Heater” instructions
in the “Installing the New Water Heater” section.
6. CLOSE the drain valve.
7. Follow instructions in the “Filling The Water Heater” section.
8. Follow the lighting instructions on the label or see page 20 under
“Lighting Instructions” to restart the water heater.
DRAIN VALVE WASHER REPLACEMENT
(See Figure 40)
1. Turn “OFF” gas supply to water heater.
2. Follow “Draining” instructions.
3. Turning counterclockwise (
), remove the hex cap below the
screw handle.
4. Remove the washer and put the new one in place.
5. Screw the handle and cap assembly back into the drain valve
and retighten using a wrench. DO NOT OVER TIGHTEN.
6. Follow instructions in the “Filling The Water Heater” section.
7. Check for leaks.
8. Follow the lighting instructions on the “Lighting & Operating Label”
section to restart the water heater.
