The correct burners and thermostat may be purchased from the same

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.
