1.   

Turn “OFF” the gas supply to 
the water heater.

  

If the main gas line shutoff valve 
serving all gas appliances is used, 
also shut “OFF” the gas at each 
appliance.  Leave all gas appliances 
shut “OFF” until the water heater 
installation is completed. See 
Figures 2 and 3.

                                            
2.   

Open a nearby hot water faucet 
until the water is no longer hot. 
When the water has cooled, 
turn “OFF” the water supply to 
the water heater at the water 
shut off valve or water meter.  
Some installations require that 
the water be turned off to the 
entire house. See Figures 2 
and 4.

                           
3.   

Check again to make sure the gas supply is “OFF” to the water 
heater. Then disconnect the gas supply connection from the 
gas control valve.

4.   

Attach a hose to the water heater 
drain valve and put the other end 
in a fl oor drain or outdoors.  (See 
Figures 2 and 5.) Open the water 
heater drain valve.

 

5.   

Disconnect the vent pipe from the draft hood where it connects 
to the water heater.  In most installations the  vent pipe can 
be lifted off after any screw or other attached devices are 
removed.  Dispose of the draft hood.  The new water heater 
has a draft hood which must be used for proper operation.

6. 

If you have copper piping to the water heater, the two copper 
water pipes can be cut with a hacksaw approximately four 
inches away from where they connect to the water heater. 
See Figure 6. This will avoid cutting off pipes too short. 
Additional cuts can be made later if necessary. Disconnect the 
temperature-pressure relief valve drain line. When the water 
heater is drained, disconnect the hose from the drain valve. 
Close the drain valve. The water heater is now completely 
disconnected and ready to be removed.

 

If you have galvanized pipes to the water heater, loosen 
the two galvanized pipes with a pipe wrench at the union in 
each line.  Also disconnect the piping remaining to the water 
heater. See Figure 7.  These pieces should be saved since 
they may be needed when reconnecting the new water heater.  
Disconnect the temperature-pressure relief valve drain line.  
When the water heater is drained, disconnect the hose from 
the drain valve.  Close the drain valve.  The water heater 
is now completely disconnected and ready to be removed. 
Mineral buildup or sediment may have accumulated in the 
old water heater.  This causes the water heater to be much 
heavier than normal and this residue, if spilled out, could 
cause staining.
