INSTALLATION INSTRUCTIONS

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 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.

FIGURE 6.

  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.
