DO NOT CONNECT ELECTRICAL
WIRING UNTIL YOU ARE
INSTRUCTED TO DO SO.
NOTICE: Connec ng electrical power
to the tank before it is completely
full of water (water must run FULL
STREAM from a hot water tap for a full
three minutes) will cause the upper
hea ng element to burn out.
Step 5:
Connect the Tempera-
ture and Pressure (T&P)
Relief Valve/Pipe
Most T&P Relief Valves are pre-installed
at the factory. In some cases, they are
shipped in the carton and must be
installed in the opening marked and
provided for this purpose and according
to local codes.
WARNING! To avoid serious injury
or death from explosion, install a T&P
Relief Valve according to the following
instruc ons:
If your water heater does not
1
have a factory installed T&P
Relief Valve, install the new
T&P Relief Valve that came with your
water heater. Do not reuse an old T&P
Relief Valve. Install a T&P Relief Valve
discharge pipe according to local codes
and the following guidelines:
• The discharge pipe should be at least
3/4" inside diameter and sloped for
proper drainage. Install it to allow
complete drainage of both the T&P
Relief Valve and the discharge pipe.
• The discharge pipe must withstand
250°F (121°C) without distor on. Use
only copper or CPVC pipe. Do not
use any other type of pipe, such as
PVC, iron, fl exible plas c pipe, or any
type of hose.
The T&P Relief Valve discharge pipe must be in-
stalled properly and piped to an adequate drain.
• Terminate the discharge pipe a maxi-
mum of six inches above a fl oor drain
or outside the building. Do not drain
the discharge pipe into the drain
pan; instead pipe it separately to
an adequate drain. In cold climates,
terminate the discharge pipe inside
the building to an adequate drain.
Outside drains could freeze and
obstruct the drain line. Protect the
drain from freezing.
DISCHARGE
PIPE
The end of the T&P Relief Valve discharge pipe
must stop no more than six inches above a fl oor
drain or outside.

• Do not place any valve or other re-
stric on between the tank and T&P
Relief Valve. Do not cap, block, plug,
or insert any valve between the T&P
Relief Valve and the end of the dis-
charge pipe. Do not insert or install
any reducer in the discharge pipe.
Make sure the insula on does not interfere with
the T&P Relief Valve's opera on.
Install the foam insulator (sup-
2
plied) on the T&P Relief Valve
body. Locate the slit running
the length of the insulator. Spread the
slit open and fi t the insula on over the
T&P Relief Valve body. Apply gentle
pressure to the insula on to ensure
that it is fully seated on the T&P Relief
Valve. Once seated, secure the
insula on with tape. Make sure that
the insula on and tape:
• Do not block or cover the T&P Relief
Valve drain opening.

• Do not block or hinder access to the
manual lever on the valve.
• Do not interfere with the T&P Relief
Valve's opera on.
