inspected and any necessary adjustments made.
1. Block up the front of the water heater 6 inches.
2. Remove the 4 nuts that attach the burner to the
heating chamber. You do not have to disconnect

not to subject them to excessive strain. Also,
make sure the fuel filter does not get damaged.
3. Let the burner fall away from the heat
exchanger. Tip the burner towards you until you
can see the electrodes and fuel nozzle.
4. Clean off carbon deposits that may have
accumulated on the tips of the electrodes.
