Instructions on how to light the pilot light on gas water heaters from Kenmore, Rheem, Bradford White, AO Smith, and other manufacturers. Lighting the pilot light when using the Honeywell, Rodgers-White, and Robertshaw gas control valves.
Every gas water heater has the lighting instructions found on the label attached to the heater. If such instructions are missing and you have to replace the pilot assembly or fix any other problem that requires re-lighting, follow the instruction found here.
I will cover different types of gas control valves that are using the piezo-electric spark ignition system. The pilot flame is ignited by the electric spark that is generated when the igniter button is depressed and can be seen through the sight glass window.
Once the pilot light is lit, it remains ON. The gas is also available to the main gas burner, and as long as there is a call from the thermostat, the pilot flame will ignite the main burner. If you require more info about problems and troubleshooting the pilot light, use this article.
Notes: If you want to learn how to light the pilot light properly, always follow the manufacturer's directions. One of these instructions says to fill the water heater with water fully, purge the air from the gas line and never light by hand.
Use your hand to push or turn the gas control knob, never tools. If the knob is blocked and does not want to operate, stop, and call the technician - do not attempt to repair.
Honeywell gas control valve, as found on Kenmore Hydrosense, has the control knob/thermostat which allows you to choose one of the three positions: ON, OFF and Pilot, and adjust the temperature of hot water. The following steps show how to light the pilot light on Honeywell gas valves:
The following steps show how to light the pilot light on Robertshaw and Rodgers-White gas valves, which are similar to the above Honeywell gas valve:
As seen from the above instruction, lighting the pilot light is not hard, but be careful it might be dangerous. That is why you should always consult the instructions on how to light the pilot light properly and safely.
