exceeded per the installation instructions in the manual

 

 

 

 

 

 

 

 

that came with the water heater.

 

 

 

4

Ensure there are no obstructions in the vent or intake air pipe.

 

 

 

1

Check wiring to the hot surface igniter assembly -

 

 

 

 

replace igniter assembly if wiring is damaged or worn.

 

 

 

2

Check resistance of the igniter at igniter assembly

 

 

 

 

plug - should be between 11 and 18 ohms at room

 

 

 

 

temperature (77° F at plug end) - replace igniter if open

 

 

The gas control valve/thermostat

 

or shorted.

 

 

3

Check igniter assembly plug and the socket on the gas

 

 

has detected an open igniter circuit.

 

 

 

 

control valve/thermostat for good connection.

 

 

 

4

Replace igniter assembly if the plug is worn or damaged.

 

 

 

5

Replace the gas control valve/thermostat if the igniter

 

 

 

 

assembly socket on the bottom of the control is worn or

 

 

 

 

damaged.

 

 

 

1

Ensure flame sensor is making good contact with the

 

 

 

 

burner flame and ensure flame is steady. Also ensure

 

 

Ignition/flame failure.

 

supply and manifold gas pressures are within the

 

 

 

requirements in the installation manual.

 

 

The gas control valve/thermostat

3

Ensure the flame sensor is clean - use fine steel wool

 

 

 

 

of retries (3) for ignition and is

 

to clean the flame sensor.

 

 

currently locked out for one hour.

4

Check igniter assembly plug and the socket on the

 

 

 

 

 

 

 

Cycle the power to the water heater

 

bottom of the gas control valve/thermostat for good

 

 

 

connection. Replace igniter assembly if the plug is worn

 

 

off and on to reset.

 

or damaged. Replace the gas control valve/thermostat if

 

 

 

 

socket is worn or damaged.

 

 

 

5

Replace igniter assembly.
