When  checking  the  temperature-pressure  relief  valve  operation, 

make sure that (1) no one is in front of or around the outlet of the 

temperature-pressure relief valve discharge line, and (2) that the 

water discharge will not cause any property damage, as the water 

may be extremely hot, see Figure 37.
If after manually operating the valve, it fails to completely reset and 

continues to release water, immediately close the cold water inlet 

to the water heater, follow the draining instructions, and replace the 

temperature-pressure relief valve with a new one.
If the temperature-pressure relief valve on the appliance weeps or 

discharges periodically, this may be due to thermal expansion.  You 

may have a check valve installed in the water line or a water meter 

with a check valve. Consult your local water supplier or a qualified 

service agency for  further information.  Do not plug the temperature-

pressure relief valve.

It is recommended that the water heater storage tank be drained 

and  flushed  every  6  months  to  reduce  sediment  buildup.  The 

water  heater  should  be  drained  if  being  shut  down  during 

freezing temperatures. See Figure 1, Features And Components 

in this manual for the location of the water heater components 

described below.

to draIn the water heater storaGe tanK:
1.  Turn off the electrical supply to the water heater.
2.  Turn off the gas supply at the Main Gas Shutoff Valve if the 

water heater is going to be shut down for an extended period. 

3.  Ensure the cold water inlet valve is open.

4.  Open a nearby hot water faucet and let the water run until the 

water is no longer hot.

5.  Close the cold water inlet valve to the water heater.
6.  Connect a hose to the water heater drain valve and terminate 

it to an adequate drain.

7.  Open the water heater drain valve and allow all the water to 

drain from the storage tank.

8.  Close  the  water  heater  drain  valve  when  all  water  in  the 

storage tank has drained.

9.  Close the hot water faucet opened in Step 4.
10.  If the water heater is going to be shut down for an extended 

period, the drain valve should be left open.

to flush the water heater storaGe tanK:
1.  Turn off the electrical supply to the water heater.
2.  Ensure the cold water inlet valve is open.
3.  Open a nearby hot water faucet and let the water run until the 

water is no longer hot. Then close the hot water faucet.

4.  Connect  a  hose  to  the  drain  valve  and  terminate  it  to  an 

adequate drain.

5.  Ensure the drain hose is secured before and during the entire 

flushing procedure. Flushing is performed with system water 

pressure applied to the water heater. 

6.  Open the water heater drain valve to flush the storage tank. 
7.  Flush the water heater storage tank to remove sediment and 

allow the water to flow until it runs clean.

8.  Close the water heater drain valve when flushing is completed.
9.  Remove the drain hose.
10.  Fill  the  water  heater  -  see  Filling  The  Water  Heater  in  this 

manual.

11.  Turn on the electrical supply to place the water heater back 

in operation.

12.  Allow the water heater to complete several heating cycles to 

ensure it is operating properly.

If a condition persists or you are uncertain about the operation of 

the water heater contact a qualified 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.
