for indoor installation only. Outdoor installations ARE NOT
covered by warranty. Failure to install the water heater

injury, or death.
Consider piping and installation when determining heater
location.
NOTICE: PROPERTY DAMAGE
All water heaters may eventually leak. Locate the water
heater where any leakage from the relief valve, related
piping, or connections will not result in damage to
surrounding areas or lower floors of the building. Any water
heater should be installed in such a manner that if it should
leak the resulting flow of water will not cause damage to the
area in which it is installed. National Plumbing codes require
a drain pan for any water heater installation. Failure to install
one is the sole responsibility of owner and/or installer.
Reference UPC 2000 (Uniform Plumbing Code) Section
510 - Protection from Damage or IPC 200 (International
Plumbing code) Section 504 - Safety Devices. Leakage
damages ARE NOT covered by warranty. In addition,
water leak detection devices and automatic water shutoff
valves are readily available at plumbing supply houses.
IT IS HIGHLY RECOMMENDED BY THE MANUFACTURER
TO INSTALL WATER LEAK DETECTION DEVICES AND
AUTOMATIC SHUTOFF VALVES IN ANY WATER HEATER
INSTALLATION WHERE A LEAKAGE OF WATER COULD
RESULT IN PROPERTY DAMAGES.
