STEP 1
Using a suitable wire gauge that meets all applicable electrical codes for the size of the breakers used, run two sets
of wire from the home s main breaker panel to the tankless water heater. NOTE: for models Eco 21, 24, & 27 you ll
need to run 3 sets of wires.
STEP 2
A separate ground conductor for each incoming circuit is required.
STEP 3
DOUBLE CHECK the electrical connections to make sure they are correct and that all wire connections are tight and
secure. Also confirm that the correct breaker size and wire gauge has been used and confirm that the unit has been
connected to a ground in accordance with applicable codes.
STEP 4
Confirm that the plumber has purged air out from the water lines prior to turning on power to the unit. Refer to
STEP 3 in the plumbing installation section.
The water heater is now installed and ready to use! Follow the General Operating Instructions below to complete
the set up. We highly recommend that this is done in conjunction with the homeowner.
6- GENERAL OPERATING INSTRUCTIONS
For the most part, operating your new tankless water heater is very similar to using any traditional water
heating system. However, it is very important that you carefully read all of the set-up procedures and operating
instructions and tips to ensure the maximum performance and energy savings from your new water heater. We
recommend that all members of the household read these General Operating Instructions.
How your new water heater works: Your Tankless Water Heater does not store hot water like a conventional
tank-type water heater. It contains very high powered heating elements that are capable of heating water
instantly on-demand as you need it. As soon as you turn on a hot water faucet, a sophisticated flow sensor
recognizes that you have turned on the water. This sensor measures the water flow rate while another sensor
measures the incoming water temperature. This information is transmitted continually to the computer logic
controls which decide how much power to send to the heating elements to heat the water to your desired
temperature.
Since your new water heater works on a demand basis, it will absolutely never run out of hot water no matter how
many back to back showers you run!
It is important to keep in mind that all tankless water heaters are subject to a maximum flow rate that they can
handle all at once. If you exceed this flow rate, the heater will not be capable of fully heating the water. How
much water you will be able to demand from your water heater at any given time will depend on the model you
have selected and your incoming water temperature. If you live in an area of the country where inlet water
temperatures average 55º F or you have cold winters, you will probably NOT be able to run multiple large water
demands at the same time, however, you will be able to run all your hot water applications back to back without
ever having to wait. You will enjoy UNLIMITED HOT WATER. SEE CHART ON NEXT PAGE.
Moreover, since a tankless water heater eliminates the ongoing thermal losses caused by storing hot water in a tank,
you will enjoy significant energy savings over a conventional water heater.
