Important Safety Instructions
CAUTION: Hydrogen gas is produced in a hot water system served by this heater that has not been used for a long
period of time (2 weeks or more). Hydrogen gas is extremely fl ammable. To reduce the risk of injury under these
conditions, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before
using any electrical appliance connected to the hot water system. When hydrogen is present, there will probably be
an unusual sound such as air escaping through the pipe as the water begins to fl ow. There should be no smoking or
open fl ame near the faucet at the time it is open.
The California Safe Drinking Water and Toxic Enforcement Act requires the Governor of California to publish a list of
substances known to the State of California to cause cancer, birth defects, or other reproductive harm, and requires
businesses to warn of potential exposure to such substances.
WARNING: This product contains a chemical known to the State of California to cause cancer, birth defects, or other
reproductive harm.
This appliance can cause low-level exposure to some of the substances included in the Act.

Location Requirements
Site location
Select a location near the center of the water piping
system. It must be installed indoors and in a vertical
position on a level surface.
The water heater should be located in an area not subject
to freezing temperatures. Water heaters located in
unconditioned spaces (i.e., attics, basements, etc.) May
require the water piping and drain piping to be insulated to
protect against freezing. The drain and controls must be
easily accessible for operation and service.
This water heater does not have suffi cient capacity for use
with a spa or hot tub.
NOTE: Local codes and requirements in your area
may require the installation of your water heater be
accomplished in a way that the bottom element is elevated
from the fl oor at least 18 inches.
2 1/2” Maximum
Pipe to
adequate
drain
At least 2” greater than the
diameter of the water heater
IMPORTANT: The water heater should be located in an
area where leakage of the tank or connections will not
result in damage to the area adjacent to the water heater or
to lower floors of the structure. Due to the normal corrosive
action of the water, the tank will eventually leak after an
extended period of time. Also any external plumbing leak,
including those from improper installation, may cause
early failure of the tank due to corrosion if not repaired.
If the owner/operator is uncomfortable with making the
repair a qualified person should be contacted. A suitable
metal drain pan should be installed under the water heater
as shown below, to help protect the property from damage
which may occur from condensate formation or leaks in
the piping connections or tank. The pan must limit the
water level to a maximum depth of 2-1/2 inches and be
two inches wider than the heater and piped to an adequate
drain. Locate the water heater near a suitable indoor
drain. Outside drains are subject to freezing temperatures
which can obstruct the drain line. The piping should be at
least 3/4” ID and pitched for proper drainage. Under no
circumstance will the manufacturer or seller of this water
heater be held liable for any water damage which is caused
by your failure to follow these instructions.

Wiring enclosed in approved conduit (if required by
local codes).
The water heater and electrical supply are properly
grounded.
Figures 3, 4, and 5 are provided as reference drawings
for the 120/240v 2-wire models only. Always reference
the wiring diagram located on the water heater for the
correct electrical connections and connect the electrical
supply to the water heater in accordance with local utility
requirements and codes.
When installing the electrical wiring to the water heater:
1. Be sure tank is completely filled with water before
making any electrical connections. (See Figure 2)
2. Disconnect the electric power.
3. Loosen the screw holding the junction box cover to the
top of the water heater and set aside.
4. Connect the electrical supply to the water heater.
A standard 1/2 inch opening has been made in the
junction box for conduit connections.
