Water Temperature Setting…
Maximum water temperature occurs while
the burner is on. To determine the water
temperature, turn on a hot water faucet and
place a thermometer in the water stream.
Water temperature at the faucet may vary
depending on season and length of pipe
from the water heater.
The factory setting of the remote control
temperature range is between 100°F (38°C)
and 120°F (49°C).
The remote control is factory preset to 100°F
(38°C).
To turn the remote control ON or OFF, press
the POWER button.
To adjust the temperature to a required setting,
press the UP arrow temperature button.
Pressing the UP or DOWN temperature
adjustment buttons will change the
temperature set point.
The temperature set point on the remote
control cannot be increased above 112°F
(44°C) when a hot water faucet is in the
open position.
Notice: The factory setting allows operating
temperatures between 100°F (38°C) and
120°F (49°C). Temperatures of up to 140°F
(60°C) can be achieved with the MAIN
(UMC-117) remote control and a dip switch
adjustment. Only qualified service personnel
should perform this adjustment. Only factory
authorized remote control(s) should be used.
The hottest temperature water will be at the
hot water faucet closest to the water heater.
Always remember to test the water
temperature with your hand before use and
remember that hotter water increases the risk
of scald injury.
Always supervise young children or others
who are incapacitated.
The water heater is equipped with a device
that will shut off the gas supply to the burner
if the water heater exceeds normal operating
temperatures. Refer to the “Before You Call
For Service” section located near the back of
this manual, or contact your dealer.
WARNING: Should overheating
occur or the gas supply fail to shut off,
turn off the manual gas control valve
to the appliance.
If the water heater has been subjected to fire,
flood, physical damage, or has been under
water, turn off the manual gas shut-off
valve(s), and do not operate the water heater
again until it has been checked by qualified
personnel.
Notice: The water heater may not operate with
a small water flow. In such case, increase the
water flow. If water heater still does not operate
and hot water faucet is completely open,
increase the temperature setting on the remote
control.
