If the flame from a gas stove burns blue, increase the supply of air by adjusting the shutter valve on the burner. When the stove is completely cool, expose the burner piping by lifting the top of the unit. Locate the burner's gas valve, and adjust the screw that controls the vent. With the burner on, adjust the shutter until the flame turns blue. Tighten the screw to hold the shutter in the new position.Know More
Gas stoves burn with a blue flame when the air-to-fuel balance is correct. When the air shutter that controls the supply of air becomes clogged, restricted or shifts, the ratio of fuel to air changes. A yellow flame indicates an air deficiency in the burner. The most common reason for air restriction is a blocked or sticky shutter valve. The oils and residue from cooked foods coat the opening or pivot point of the valve over time.
A faulty or oversized burner orifice also causes air restriction in gas stoves. Yellow flames cause irregular heating, soot on the cookware and burner failure. If you cannot locate the adjustment valve or cannot safely lift the top surface of the stove, call a trained gas appliance technician. Discontinue use of the stove until the source of the air restriction is fixed.Learn more in Ovens & Ranges
To clean stove burner grates, soak them in warm, soapy water, and scrub with a non-metal soap pad, rinse the grates well, and seal each grate in a plastic bag with a 1/2 cup of household ammonia. Wait overnight, and rinse the grates again, then polish the grates with a soft cloth.Full Answer >
Gas burners work using a mixture of natural gas and oxygen that is ignited by a pilot light, or, in newer stoves, an electric spark igniter. The height of the flame is determined by the amount of gas fed into the burner. An alternative fuel source is propane.Full Answer >
When compared in terms of energy efficiency, a gas stove is much more efficient than an equivalent electric stove. This results in a gas stove costing a user much less to run than an electric one.Full Answer >
Converting a stove from natural gas to propane involves changing internal parts to compensate for the differences in the operating pressure of the two gases. It requires installation of a conversion kit. If the kit is not available, owners should not attempt to convert the appliance.Full Answer >
