Plumbing Installation - Eco-Smart ECO 36 Installation Instructions & Owner's Manual

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. We recommend that this product 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 THE 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 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 Sate of Kentucky require a
pressure relief valve.
3. The maximum recommended operating water pressure is 150 PSI. If your water pressure is higher than
this, we recommend that a pressure reduction valve be installed on your main incoming water supply line
prior to installing your tankless water heater.
4. Flexible water heater hoses can and are recommended to be used with your water heater as part of 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 TIGHTEN SO THE FLOW SENSOR ON THE UNIT
IS NOT LOOSENED OR DAMAGED. Serious internal damage to your water heater can occur of 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.
5. We recommend that all water pipe within 3 feet of the inlet and outlet hoses be copper, although other
forms of plastic tubing are acceptable as long as they are rated for high temperature applications.
