instructions before beginning.
If you are not sure you can
safely complete the installation, seek
assistance from any of the following
sources:
• Schedule an appointment with a
qualified person to install your water
heater.
• Call our Technical Assistance Hotline
which is listed on the water heater's
warranty sheet.
Install a metal drain pan that

is piped to an adequate drain.

Set the water heater in place

taking care not to damage
the drain pan. When installing
directly on carpet, the water heater
must be installed on a wood or metal
base that extends beyond the
dimensions of the water heater (width
and depth) by at least 3 inches in any
direction. If the water heater is
installed on carpet in an alcove or
closet, the entire floor must be
covered by a wood or metal panel.
NOTICE: Most codes require setting
the water heater in a metal drain pan
piped to an adequate drain. The drain
pan helps avoid property damage
which may occur from condensation
or leaks in the piping connections or
tank. The drain pan must be at least
two inches wider than the diameter
of the water heater. Install the drain
pan so the water level is limited to a
maximum depth of 1-¾".
Verify the water heater is
4
properly set in place. Check
that:
• There is adequate space to install
the T&P Relief Valve discharge pipe
and that it can be piped to a sep-
arate drain (and not into the drain
pan, unless otherwise allowed by
local and state codes).
• There is adequate access and space
around the water heater for future
maintenance.
• The water heater is installed verti-
cally.
Step: 5
Connect the
Temperature 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 "T&P Relief Valve" and
according to local codes.
Figure 37 - Temperature and Pressure Relief
Valve
WARNING! To avoid serious injury
or death from explosion, install a
T&P Relief Valve according to the
following instructions.
If the T&P Relief Valve was not factory
installed, 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 ¾" inside diameter and sloped
for proper drainage. Install it to
allow complete drainage of both the
T&P Relief Valve and the discharge
pipe.
