4- PLUMBING INSTALLATION
PLEASE READ THESE INSTRUCTIONS THOROUGHLY AND COMPLETELY BEFORE INSTALLATION AND BEFORE USE.
FAILURE TO DO SO COULD CAUSE PROPERTY DAMAGE OR SERIOUS PERSONAL INJURY OR DEATH, AND
VOID YOUR WARRANTY.
Please follow all plumbing instructions carefully. This product must be installed by a licensed and qualified
plumber in accordance with all applicable national, state, provincial, and local plumbing codes.
IMPORTANT NOTES:
1. DO NOT SOLDER ANY PIPES WITH UNIT CONNECTED TO PIPES - IF YOU DO, YOU MAY DAMAGE THE
FLOW SENSOR AND VOID THE WARRANTY. WE RECOMMEND USE OF WATER HEATER FLEX HOSES FOR EASE OF
INSTALLATION
2. The ECOSMART Tankless Water Heater is equipped with both computer-controlled and electro-mechanical
auto-resetting thermostat switches for high-limited temperature protection. Since this product does not use a
storage tank, the use of a temperature pressure relief valve (T&P) is not required for most installations. UL
Standard 499 does NOT require that a pressure relief valve be used. However, a T&P valve may be required to
meet installation codes in your area. If one is required, install the pressure relief valve in accordance with your
code and ensure that it operates correctly and that air is purged from the valve prior to installing your water
heater. When connecting to Flex or High Temperature CPVC pipe, we recommend that a T&P valve be used for
added safety. If a pressure relief valve is used, it should be connected to a drain.
Please note: Installations in the Commonwealths of Massachusetts and State of Kentucky require a pressure
relief valve.
The maximum recommended operating water pressure is 100 PSI. If your water pressure is higher than this,
3.
we recommend that a pressure reduction valve be installed on your main incoming water supply line prior to
installing your tankless water heater.
Flexible water heater hoses can and are recommended to be used with your water heater as part of
4.
the installation. WHEN CONNECTING THE INLET WATER TO THE UNIT MAKE SURE YOU USE A WRENCH
TO HOLD THE UNITS CONNECTION AND ANOTHER WRENCH TO TIGHTHEN SO THE FLOW SENSOR ON
THE UNIT IS NOT LOOSENED OR DAMAGED. Serious internal damage to your water heater can occur
if you over-tighten the water heater inlet connections at the unit or if you solder any pipe to the inlet
and outlet connections. Such damage is NOT covered under the warranty.
We recommend that all water pipe within 3 feet of the inlet and outlet hoses be copper although other
5.
forms of plastic tubing are acceptable as long as they are rated for high temperature applications.
