1- Defective gas controller2- Thermostat/ aqua stat not calling for heat3- electric shut offTripped or defective safety device, gas valve set on pilot, bad transformer. Don`t kill yourself looking for the aquastat. That is a boiler control and your furnace does not have one.Electic good-- whatelse can I test?
Gas enters the bottom of the Bunsen burner, where it travels up to mix with air before moving up the stem to meet the flame.
No. You can not light a Bunsen Burner by turning on gas and oxygen. It takes a spark. (Actually, it takes a certain temperature to get the reaction started. The spark simply brings the material extremely near the spark up to that temperature.)
Turning off the Bunsen burner at the gas tap puts out the fire because the gas is a switch that lets the amount of gas that you want to burn. And if you turn it off then it would let no gas through and there for would not let the Bunsen burner light up. Hope this helps
A gas furnace works by heating up the element inside the furnace. The gas comes into the furnace and is lit by a spark that comes from the pilot light. The fire heats up the element and air from the fan pushes the heat into the house.
First you need a tripod,gauze mat and a container whatever your gonna heat. Connect the hose to the gas. While lighting the Bunsen burner slowly turn the gas on. Make sure that the hole is close when you light it.
You take a match, light it up and turn the knob on the side of the burner.
it heats up the thermo couple which opens up the gas control valve allowing gas to flow to the main burner. if the pilot goes out the thrmo couple will cool and shut the gas valve so gas does not come out

An extra puff usually means that there is an excess build up of gas, The first thing I would check is the burners for dirt build up.
This question is not specific enough for a good answer. What is the appliance? A furnace? A cooktop burner? An oven? The first thing to check would be the igniter, which is what typically "lights" the gas coming from the valve. You can check an igniter with a simple continuity test using a test meter. If the pilot is lit, then there is no igniter, or the igniter lites the pilot, so if the pilot is lit how could it be the igniter. Bad thermocouple, this tells the gas valve that the pilot light is lit, if the gas valve does not know the pilot is lit it will not allow gas to come out of the valve, this is a safety feature so your unit does not blow up.
collar for turning to close and open the air hole air hole for allowing oxygen to mix with the gas barrel for the gas to go up gas hose for allowing gas into the Bunsen burner
