WARNING
Failure to install and maintain a new, listed temperature and pressure relief valve will release the manufacturer from any
claim, which might result from excessive temperature and pressures.

Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank for a long period
of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE. To prevent the possibility of
injury under these conditions, we recommend the hot water faucet to be open for several minutes at the kitchen sink before
you use any electrical appliance, which is connected to the hot water system. If hydrogen is present, there will be an
unusual sound such as air escaping through the pipes as hot water begins to flow. Do not smoke or have open flame near
the faucet at the time it is open.

Keep clear of the combination temperature and pressure relief valve discharge line outlet. The discharge may be hot
enough to cause scald injury. The water is under pressure and may splash.
Setting the water temperature to the maximum set point can result in scalding hot water delivered to the faucets. It is
highly recommended that the maximum setpoint be adjusted to the lowest temperature possible for the needs of the
installation. See following section to change the maximum setpoint limit (max setpoint). Make sure the water heater
control display is not in a public area that can result in the temperature settings being improperly adjusted. See previous
warning on scalds and an ASSE approved mixing valve.

CAUTION
If sweat fittings are to be used, DO NOT apply heat to the nipples in front or side of the water heater. Sweat the tubing to
the adapter before fitting the adapter to the water connections. It is imperative that heat is not applied to the nipples
containing a plastic liner.
This water heater must not be operated without installing the mixing valve included in the box shipped with the water
heater located in the control compartment. Refer to the instructions supplied with the mixing valve for proper installation
and settings.

INSTRUCTIONS FOR CONNECTIONS
1. BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE MAIN WATER SUPPLY VALVE. After shutting
off the main water supply, open a faucet to relieve the water line pressure to prevent any water from leaking out of the
pipes while making the water connections to the water heater. The COLD water inlet and HOT water outlet are
identified on the water heater. Make the proper plumbing connections between the water heater and the plumbing
system to the house. Install a shut-off valve in the cold water supply line.

system to the house. Install a shut-off valve in the cold water supply line.
2.
If this water heater is installed in a closed water supply system, such as the
one having a back-flow preventer in the cold water supply, provisions must be
made to control thermal expansion. DO NOT operate this water heater in a
closed system without provisions for controlling thermal expansion. Warranties
do not cover damages from thermal expansion such as pressure bulges and/or
deformities. Your water supplier or local plumbing inspector should be
contacted on how to control this situation

3. After installation of the water lines, open the main water supply valve and fill
the water heater. While the water heater is filling, open several hot water
faucets to allow air to escape from the water system. When a steady stream of
water flows through the faucets, close them and check all water connections
for possible leaks.

SCALDING
This water heater can deliver scalding temperature water at any faucet in the system.
Be careful whenever using hot water to avoid scalding injury. Certain appliances such
as dishwashers and automatic clothes washers may require increased temperature
water.
