NOTE: The equipment shall be installed in accordance with those installation regulations required in the area where the

installation is to be made. These regulations shall be carefully followed in all cases. Authorities having jurisdiction shall be

consulted before installations are made.

All wiring on water heaters shall be in accordance with the National Electrical Code and/or local regulations.

Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal injury, or loss

of life. Read and understand the entire manual before attempting installation, start-up, operation, or service. Installation

and service must be performed only by an experienced, skilled installer or service agency.

This water heater contains very hot water under high pressure. Do not unscrew any pipe fittings or attempt to disconnect

any components of this water heater without positively assuring that the water is cool and has no pressure. Always wear

protective clothing and equipment when installing, starting up or servicing this water heater to prevent scalding injuries.

Do not rely on the pressure and temperature gauges to determine the temperature and pressure of the water heater.

This water heater contains components that become very hot when the boiler is operating. Do not touch any components

unless they are cool.

Failure to follow all instructions in the proper order can cause personal injury or death. Read all instructions, including all

those contained in component manufacturers’ manuals before installing, starting up, operating, maintaining, or servicing

the water heater.

To reduce the risk of excessive pressures and temperatures in this water heater, install temperature and pressure

protective equipment required by local codes but no less than a combination temperature relief valve certified by a

nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials,

as meeting the requirements for Relief Valves and Automatic Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22-

latest edition. This valve must be marked with a maximum set pressure not to exceed the marked working pressure of

the water heater. Install the valve into an opening provide and marked for this purpose in the water heater, and orient it

or provide tubing so that any discharge from the valve will exit only within 6 inches above, or at any distance below, the

structural floor, and cannot contact any live electrical part. The discharge opening must not be blocked or reduced in size

under any circumstances.
