While any hot water is being provided,
the temperature seng can only be
adjusted between 98° F and 110° F.

Check local codes for the maximum water
temperature seng allowed when used
in nursing homes, schools, day care
centers, and all other public applicaons.

If power is interrupted and a newly
installed unit with a controller has not
been powered for at least 6 hours then
the temperature will return to the default
seng of 104° F (40° C).

There may be a variaon between the
temperature displayed on the
temperature controller and the
temperature at the tap due to weather
condions or the length of pipe to the
water heater.

Water temperatures over 125° F (52° C) can cause severe burns or scalding
resulng in death.
Hot water can cause rst degree burns with exposure for as lile as:
3 seconds at 140° F (60° C)
20 seconds at 130° F (54° C)
8 minutes at 120° F (49° C)
Children, disabled, or elderly are at highest risk of being scalded.
Feel water before bathing or showering.
This water heater requires a minimum ow rate to operate. This rate can be found on the specicaon page in
this manual. In some cases when you are not geng hot water or if the water alternates between hot and cold,
it is due to the water ow being below or close to the minimum ow rate. Increasing the ow rate should
resolve these problems in these cases.
If you are experiencing issues with higher temperature sengs, then reduce the temperature seng. Selecng a
temperature closer to that which is actually used at the faucet will increase the amount of hot water being
delivered to the faucet, due to less cold water mixing at the xture.
Adjusng the Temperature
1.Ensure the controller is “ON” and that the Priority
icon is displayed.
2.Press the “UP” or “DOWN” buons as needed to set
the controller to the desired temperature.
-The temperature will increase by 2 degree
increments between 98-110 F. Once above 110 F
the temperature will change by 5 degree incre-
ments.
3.Proceed to open the tap to allow water to ow
through the unit allowing combuson to begin.
-During the call for hot water while the burners are
acve, the “Combuson” icon will appear on the
screen.
