12 • Residenal Electric Water Heater Use and Care Guide
4
Connect the free ends of the
two 22 AWG wires to the
shut-o switch on the
condensate pump in accordance with
the condensate pump manufacturer’s
recommendaons.
Step 7:
Install Condensate
Drain Line:
NOTICE: Barbed drain and exible
tubing for condensate drain line come
pre-installed from the factory.
• Flexible tubing must be used to
connect the condensate drain to a
suitable drain or condensate pump.
• Condensate drain line should be
installed in condioned areas
only. Install approved insulaon
on the condensate drain line to
prevent condensaon from forming
on the outside of the drain line.
Condensaon drain lines installed
in areas that are subject to freezing
temperatures should be wrapped
with a naonally recognized heat
tape. Install per manufacturer’s
instrucons.
• Do not connect condensate drain
line with other drain or discharge
lines into a single (common) pipe
or line. Each line (condensate drain
line, temperature and pressure relief
valve discharge pipe, etc.) should be
independently run to an adequate
drain.
• Slope the condensate drain line
toward the inside oor drain or
condensate pump.
• The condensate drain line and
connecons to the drain piping must
comply with all local codes.
• If a condensate pump is installed, it
should be wired to shut o the heat
pump in the event the condensate
pump fails or the oat switch in the
pump acvates (see “Connecng
the Condensate Pump Oponal
Overow Shut-O Switch” on page
11).
• Allow enough length on the 5/8” ID
exible plasc tubing (pre-installed
from the factory) to access an
adequate drain.
Step 8:
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 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 instrucons:
If your water heater does not 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:
1
The discharge pipe should be
at least 3/4” (19 mm) inside
diameter and sloped for
proper drainage. Install it to allow
complete drainage of both the T&P
Relief Valve and the discharge pipe.
2
The discharge pipe must
withstand 250°F/121°C
without distoron. Use only
copper or CPVC pipe. Most homes use
copper water pipes, but some use
CPVC or cross-linked polyethylene
(PEX). Use ngs appropriate for the
type of pipe in your home. Do not use
any other type of pipe, such as PVC,
iron, exible plasc pipe, or any type
of hose.
Figure 15 - The T&P Relief Valve discharge pipe
must be installed properly and piped to an
adequate drain.
3
Terminate the discharge pipe
a maximum of 6” (15 cm)
above a 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.
4
Do not place any valve or
other restricon 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 discharge pipe. Do
not insert or install any reducer in the
discharge pipe.
