Sharp, noisy blue flame=too much air
Blue flame with defined inner lighter blue cone= just right
Soft blue flame with yellow tips=not enough air, or using LP gas
Most times can be adjusted with the primary air shutter on the burner tube, being careful to check for good ignition after adjustment.
Caution: a yellow flame can carbon/clog up the heat exchanger eventually.
its hot!
its heating
The gas furnace pilot (flame is lit all the time) is sometimes referred to as a pilot light, but no matter what you call it, its purpose is to serve as a small ignition flame for the gas burner. And when this little flame fails to operate properly or go out, it's one of the most common reasons a gas furnace will fail to operate.
If the furnace is direct ignition, The HSI or spark ignites the flame. A flame sensor passes current through the flame, if current is present the main.
flame sensor
with gas? hence gas furnace? theres a gas pipe that puts the gas into 3-4 tube things tht keep lit by the gas bruhhh
a complete flame or a blue flame
Yellow flames from a natural gas furnace indicate that the combustion ratio is off and you have too much excess air in the mixture, if the discolored flame is isolated in the burner meaning on only 1 out of 3 or more then the burner/orifice may be out of alignment or there maybe a crack in the exchangers cell.
The main circuit board in your furnace sends a small ac signal to the flame rod so now you have an ac potential from the body of the furnace to the flame rod, When the flame comes on between the body of the furnace and the rod it rectifies the ac in to dc, The flame actually acts like a diode. When this dc voltage is sensed by the control board it knows there is a flame present and thus keeps the gas valve on. Hope this helps
I'm assuming you mean the furnace? If the pilot light keeps going out on the furnace, you probably have a rusted through or cracked heat exchanger. Unfortunately the only way to fix the problem is to replace the furnace. IM THE ONE WHO ASKED THE QUESTIONN THIS IS NOT A FURNACE IT IS A GAS HEATER THAT HE PUT IN HIS DINNING ROOM
