7

Turn the cold water supply 
valve OFF. 

8

Open the drain valve on the 
water heater.

Draining the old water heater.

9

Also open a hot water faucet 
to help the water in the tank 
drain faster. 

10

When the tank is empty, 
disconnect the Temperature & 
Pressure (T&P) Relief Valve 

discharge pipe. You may be able to 
reuse the discharge pipe, but do not 
reuse the old T&P Relief Valve.  A new 
T&P Relief Valve comes installed on 
your water heater (or on some models, 
is in the carton with the water heater).

discharge 

pipe.

11

Disconnect the water pipes. 
Many water pipes are 
connected by a threaded 

union which can be disconnected with 
wrenches. If you must cut the water 
pipes, cut the pipes close to the water 
heater’s inlet and outlet connec  ons, 
leaving the water pipes as long as 
possible. If necessary, you can make 
them shorter later when you install 
the new water heater.

12

Remove the old water heater.
 

WARNING! Use two or more people 

to remove or install water heater. 
Failure to do so can result in back or 
other injury.

Step 4:

Installing the new
water heater

1

Completely read all instruc-

 ons before beginning. If you 

are not sure if you can 

complete the installa  on, DO NOT 
RETURN THIS UNIT TO THE STORE. 
Seek assistance from any of the 
following sources:
•    Schedule an appointment with 

a qualified person to install your 
water heater.

•   Call our Technical Assistance Hot-

line at 

   1-800-821-2017

2

Install a suitable drain pan 
that is piped to an adequate 
drain. 

3

Set the water heater in place 
taking care not to damage 
the drain pan. 

NOTICE: 

Most codes require se   ng 

the water heater in a suitable drain 
pan piped to an adequate drain. The 
drain pan helps avoid property dam-
age which may occur from condensa-

 on or leaks in the piping connec  ons 

or tank. The drain pan must be at 
least two inches wider than the diam-
eter of the water heater.  Install the 
drain pan so the water level is limited 
to a maximum depth of 1-3/4”.

4

Verify that the water heater 
is properly set in place. Check 
that:

•   The T&P Relief Valve will not be in 

contact with any electrical parts.

•   There is adequate space to install 

the T&P Relief Valve discharge pipe 
and that it can be piped to a sepa-
rate drain (and not into the drain 
pan).

•   There is adequate access and space 

around the water heater for future 
maintenance.
