BLOWER AND BURNER ASSEMBLY
BURNER REPLACEMENT:
1. Turn off the gas supply and electricity to the water heater.
2. Disconnect the spark ignition cable and ground wire plus the flame sensor wire at their connection points
on the flange plate.
3. Disconnect the vacuum hose at the air intake connection if necessary. Disconnect the pressure hose at
blower outlet connection.
4. Disconnect the gas valve from the blower at the gas valve flange by unscrewing the 4 retaining screws.
Keep the o-ring that is located in the flange groove. This o-ring seals the flange to the gas valve.
5. Remove the 4 fasteners joining the blower flange to the adapter tube. Save the silicone gasket between
the blower flange and the adapter tube.
6. Move the blower aside and support it so that it will not hang from the power connection wires.
