5. Plumbing Requirements and Precautions
• Please follow all plumbing instructions carefully. This product must be installed in accordance with all national,
state, provincial, and local plumbing codes. We recommend consulting with your municipality or a qualied
plumber if you have questions relating to plumbing codes for your area prior to installing.
• The plumbing installation must be completed before the electrical installation.
• DO NOT solder any pipe with the unit connected to the pipe. The heat from soldering
may cause damage to the ow sensor. Doing so will void the warranty.
• The use of a temperature pressure relief valve (T&P) is not required for most
installations because the tankless water heater does not use a storage tank. UL
Standard 499 does not require that a pressure relief valve is used, although it may
be needed to meet installation codes in your area. In such cases, the pressure relief
valve should be installed in accordance with local codes. It is important to ensure
that the unit is operating correctly, and that air is purged from the valve prior to
installing the water heater.
• A T&P valve is recommended for added safety when connecting to plumbing rated Metal, Flex or High-
Temperature CPVC piping.
NOTE: A pressure relief valve is required for installations in the Commonwealth of Massachusetts
and State of Kentucky. Please check your local installation codes for any special requirements.
• The plumbing installation requires piping that can withstand pressure up to 8 BAR.
