How long should a pilot light flame be?
How long should a pilot light flame be?
A proper pilot flame should be blue with a yellow tip and should be strong enough to cover about 1/2 inch at the end of the thermocouple tip. If the flame is too strong and improperly adjusted, it will be blue but may be noisy and lift off the thermocouple, causing improper furnace operation.
Can pilot flame be too big?
What happens if the pilot light is too long? If the pilot flame is too long it will not reach the sensors and they could not ignite the system. Also, the bright orange light does not provide the temperature needed for the thermocouple to work.
How tall should the flames be on a gas water heater?
This assembly includes the pilot light and gas burner itself. The pilot light and burner adjustment are key to proper and energy-efficient operation of the water heater. The gas flames should about 1/2 inch in height and should have blue tips (yellow flames indicate dirty burner jets or an improper air mixture).
How big should pilot hole be on water heater?
When the orifice is clear, the flame should be about 1 1/2 to 2 inches high, and it should burn with a uniform blue color. Avoid bending the pilot or thermocouple tubes when you pull them out of the heater. If either tube kinks, you’ll have to replace it.
Where is the pilot light on a gas water heater?
The pilot is behind a cover plate at the bottom of the heater. Although an increasing number of gas water heaters have electronic igniters, many still rely on a pilot light to ignite the burner when the heater cycles on.
Where does the gas line fee go in a water heater?
The gas line fees into a gas burner control module that serves as a kind of thermostat for the water heater. It also controls the ignition of the pilot light. From the control module, we now proceed to the gas burner assembly. This includes the pilot light and gas burner itself.

How does the flame Guard system work on a water heater?
The burning vapors literally “burn themselves out” without escaping back into the room. In the event of a flammable vapor incident, the Flame Guard® Safety System shuts off the gas supply to the water heater’s burner and pilot, preventing re-ignition of any remaining flammable vapors in the area.
What to do if your pilot light flame is yellow?
The issue can typically be fixed by cleaning out the air intake valve to the pilot light, which should only be done by a professional who knows how to access and repair the part.
