Installing the water heater.
Local Installation Regulations
This water heater must be installed in accordance with these instructions, local codes, utility codes, utility company requirements or, in the absence of local codes, the latest edition of the National Electrical Code. It is available from some local libraries or can be purchased from the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269 as booklet ANSI/NFPA 70.
If the water heater is to be installed in a restaurant, or other location where NSF International listing is required, it must
be weather sealed to the floor, a raised base, or on a shelf so that seepage cannot accumulate under it; or elevated to provide at least (6) inches of clearance from the floor.
In order to meet NSF International requirements for Standard 5, the base of the water heater must be sealed to the floor to prevent seepage underneath. Apply a 3/8" bead of RTV Silicone completely around the floor edge of the base of the tank.
The location chosen for the water heater must take into consideration the following:
NOTICE: DO NOT use fittings on top of the unit as handles or lift points.
Location
Locate the water heater in a clean dry area as near as practical to the area of greatest heated water demand. Long un-insulated hot water lines can waste energy and water.
Place the water heater in such a manner that the thermostat and element access panels can be removed to permit inspection and servicing such as removal of elements or checking controls.
The water heater and water lines should be protected from freezing temperatures.
DO NOT install the water heater in outdoor, unprotected areas or near any other appliances where high temperatures are present, such as wood burning stoves, boilers, or furnaces. High temperatures can warp or otherwise damage the nonmetallic construction of this water heater.
Make certain the floor underneath the water heater is strong enough to sufficiently support the weight of the

Installing the water heater.
Thermal Expansion
Determine if a check valve exists in the inlet water line. Check with your local water utility. It may have been installed in the cold water line as a separate back flow preventer, or it may be part of a pressure reducing valve, water meter or water softener. A check valve located in the cold water inlet line can cause what is referred to as a “closed water system”. A cold water inlet line with no check valve or back flow prevention device is referred to as an “open” water system.
As water is heated, it expands in volume and creates an increase in the pressure within the water system. This action is referred to as “thermal expansion”. In an “open” water
system, expanding water which exceeds the capacity of the water heater flows back into the city main where the pressure is easily dissipated.
A “closed water system”, however, prevents the expanding water from flowing back into the main supply line, and the result of “thermal expansion” can create a rapid and dangerous pressure increase in the water heater
and system piping. This rapid pressure increase can quickly reach the safety setting of the relief valve, causing it to operate during each heating cycle. Thermal expansion, and the resulting rapid and repeated expansion and contraction of components in the water heater and piping system can cause premature failure of the relief valve,
and possibly the heater itself. Replacing the relief valve will not correct the problem!
The suggested method of controlling thermal expansion is to install an expansion tank in the cold water line between the water heater and the check valve (refer to the illustration on page 9). The expansion tank is designed with an air cushion built in that compresses as the system pressure increases, thereby relieving the over pressure condition and eliminating the repeated operation of the relief valve. Other methods of controlling thermal expansion are also available. Contact
your installing contractor, water supplier or plumbing inspector for additional information regarding this subject.
Inspect Water Heater
Inspect the water heater for possible damage. Check the markings on the rating plate of the water heater to be certain the power supply corresponds to the water heater requirements.
NOTICE: DO NOT operate the unit without the vacuum relief valve for any reason.
Doing so will void the manufacturer’s warranty.
Vacuum Relief Valve
The vacuum relief valve, which must be used when installing the water heater, is factory installed.
The cold water inlet has a vacuum relief valve connected to it. Certain conditions in the field may produce a vacuum or negative pressure condition inside the water heater’s tank. This negative pressure can cause the tank to fail. The vacuum relief valve provides
a means to eliminate the negative pressure or vacuum by admitting air into the tank to equalize the pressure.
It is not recommended to pull a vacuum on the unit.
If a vacuum is pulled on the unit, refer to the "To Fill the Water Heater" section to ensure the unit is full of water before operating.
6
A new combination temperature and pressure relief valve, complying with the Standard for Relief Valves for Hot Water Supply Systems, ANSI Z21.22, is supplied and must be installed in the opening provided and marked for the purpose on the water heater. No valve of any type should be installed between the relief valve and the tank. Local codes shall govern the installation of relief valves.
Temperature and Pressure Relief Valve
! WARNING: The pressure rating of the relief valve must not exceed 150 psi, (1034 kPa), the maximum working pressure of the water heater as marked on the rating plate.
The BTUH rating of the relief valve must not be less than the input rating of the water heater as indicated on the rating label located on the front of the heater
(1 watt=3.412 btu/h).
Connect the outlet of the relief valve to a suitable open drain so that the discharge water cannot contact live electrical parts or persons and to eliminate potential water damage.
Piping used should be of a type approved for hot water distribution. The discharge line must be no smaller than the outlet of the valve and must pitch downward from the valve to allow complete drainage (by gravity) of the relief valve and discharge line. The end of the discharge line should not be threaded or concealed and should be protected from freezing. No valve of any type, restriction or reducer coupling should be installed in the discharge line.
NOTICE: Auxiliary catch pan MUST conform to local codes.
NOTICE: Water heater must be centered in drain pan.
Drain Pan
The water heater should not be located in an area where leakage of the tank or connections will result in damage to the area adjacent to it or to lower floors of the structure. Where such areas cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the water heater.
Under no circumstance will the manufacturer be held liable for any water damage in connection with this water heater.
Drain pan kits are available from the store where the water heater was purchased, or any water heater distributor.

Water Supply Connections
NOTICE: DO NOT attempt to turn any fitting connected to the water heater union hex nuts that are tightened.
NOTICE: The hex nut connections on the units use rubber seal rings to provide the water tight seal. DO NOT use pipe sealant on this joint. DO NOT torque the union hex nuts to over 35 ft-lbs when reinstalling the components.
SOLDER WITH CARE!!!
If sweat connections are used, DO NOT apply heat directly to any component directly connected to the water heater. Assemblies should be built to a minimum length of 12” before attaching to any connection on the water heater to avoid damaging the unit.
! WARNING: Failure to follow the instructions provided in this manual may permanently damage
the unit and void the manufacturer’s warranty.
Refer to the illustration on the next page for suggested typical installation. The installation of unions or flexible connectors is recommended on the hot and cold water connections so that the water heater may be easily disconnected
for servicing if necessary. If flexible water connections are used, the must comply with the standard for flexible Water Connectors, ASME A112.18.6/ CSA-B125.6. The HOT and COLD water connections are clearly marked on the water heater. Install a shutoff valve in the cold water line near the water heater. Refer to the following illustration for suggested typical installation.
The hot water connection is provided with a ¾” or 1” connection depending on the size of the unit. A metal fitting should be used for the
connection to the unit at this location. The hot water connection contains a plastic cap to contain a rubber seal ring that is used to form a water tight connection. Take care when removing the plastic cap so the rubber seal ring is not lost. Be sure the rubber seal ring is seated inside the union hex nut before making the final connection. DO NOT use pipe sealant on this joint. DO NOT torque the union
hex nuts to over 35 ft-lbs when reinstalling the components.
The cold water connection and the temperature and pressure relief valve are supplied with ¾” NPT
connections. They may be temporarily disconnected from the unit to ease installation by loosening the union hex nuts connecting the fittings to the unit. The connection of these parts to the unit use rubber seal rings to form a water tight connection. Re-use the rubber seal rings that are provided with the unit when re-installing these components. Follow the instructions listed for the hot water connection to reconnect the union hex nuts.
