BURNER AND THERMOSTAT INFORMATION
It is recommended that this water heater be installed with the following
burners and thermostat:
The correct burners and thermostat may be purchased from the same
supplier that provided the water heater to you.
Installing the Burner: It is recommended that the burner be installed so that
the face of the burner head is between 1/8 of an inch to 5/8 of an inch from
the inside wall of the combustion chamber (see Figure 3). The position of the
burner head can be checked by putting your hand through the peep site hole
and feeling the location of the burner head. If the peep site hole is too small
for you to fit your hand through, then you can check the burner position with a
mirror. The burner head SHALL NOT extend inside the combustion chamber.
The burner is secured to the water heater by three 5/16” nuts.
CAUTION: Do not operate the burner if it is wet. If the burner gets wet, have
a qualified technician examine the burner before putting it back into operation.
Figure 3
Installing the Thermostat: The water heater comes with the thermostat well
installed in the tank. A Honeywell Aquastat 4103A1100 needs to be installed
in the thermostat well.
