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

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 

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

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.
