1.
 
 Turn “OFF” the gas supply to the water 
heater.
 
If the main gas line Shut-off 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.  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.  Open the water 
heater drain valve.  Open a nearby hot 
water faucet which will relieve pressure 
in the water heater and speed draining. 
The water passing out of the drain valve 
may be extremely hot.  To avoid being 
scalded, make sure all connections are 
tight and that the water fl ow is directed 
away from any person, see Figures 2 
and 5.

5.  Disconnect the vent pipe from the blower assembly 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. Make sure 
existing vent complies with maximum and minimum vent lengths on 
page 17.
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.
