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 qualified installer

to check the water heater.

Read this manual first. 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.

LEAKAGE CHECKPOINTS

Never use this water heater unless it is completely filled with water.

BTo prevent damage to the tank, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” gas to the water heater.

A

*Condensation may be seen on pipes in humid weather or pipe

 

connections may be leaking.

 

 

C

B. *The anode rod fitting 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 fitting.

 

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 fitting.

G. Combustion products contain water vapor which can condense

 

 

G

on the cooler surfaces of the tank. Droplets form and drip onto

 

 

E

 

the burner or run on the floor. 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 floor 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 fitting. If cotton is wet, follow

“Draining” instructions in the “Periodic Maintenance” section and then remove fitting. Put pipe dope or teflon tape on the threads and replace. Then follow “Filling the Water Heater” instructions in the “Installing the New Water Heater” section.
