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 federal, 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.
2. The Econobec tankless water heater is equipped with both computer-controlled and electromechanical 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 PVC 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.
3. The maximum recommended operating water pressure is 7.03 kg/cm
2
(100 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. Serious internal damage to your water heater can occur if you over-tighten the water heater inlet hose 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 1m (3 feet) of the inlet and outlet hoses be copper although other forms of
plastic tubing are acceptable as well, as long as they are classified for high temperatures.
STEP 1
IMPORTANT: Bring the HOT WATER and COLD WATER lines to the heater. We recommend that a manual shut-off valve
(ball valve) be installed on the inlet side of the water heater so there is a convenient shut-off point available in the event that
future maintenance or servicing is required.
Before connecting these pipes to the water heater hoses if used it is extremely important to FLUSH the lines to eliminate all
plumbing paste or residue in the lines caused by any welding or soldering.
STEP 2
Connect the HOT WATER line to the water heater marked HOT WATER OUT (1 inch connector) located in the middle of the
right side of the water heater when facing unit. Connect the COLD WATER line to the water heater marked COLD WATER
IN (1 inch connector) on the lower, right side when facing unit. DO NOT USE TEFLON TAPE OR PASTE on compression
fittings.
STEP 3
IMPORTANT: After tightening both compression fittings at the water heater, open several hot water faucets and allow
water to run though the water heater for at least 2 to 3 minutes. This process purges all the air from the water lines and
MUST be performed prior to turning on the power at the unit. FAILURE TO FOLLOW THIS STEP CAN CAUSE
PERMANENT DAMAGE TO THE HEATING ELEMENTS. When any maintenance is performed on the water heater or the
home’s plumbing system that may introduce air into the plumbing pipes, it is important to turn the power off to the water
heater and purge the air out of the lines before allowing the unit to power up.
