Noisy pilot light Vulcan Quasar 40

I have a Vulcan Quasar 40 wall furnace and the pilot light is noisy. I can stop the noise by using the pilot light regulation screw to reduce the flow of gas to the pilot. But this weakens the flame to the point that when the thermostat turns off the main gas burner (i.e., when desired room temperature reached), the pilot light seems not to have sufficient strength to remain alight.

Simply clean out the jet tube with a fine wire, the sound you hear is the gas blowing by the irregular edges, and swirling and not mixing and producing sound waves, (Bit like a flute) So, you need to clean the tube right out, and smooth off the end again, & sorta "Countersink", Flame the end too, at the end.use a very fine needle file, and make it look like new, that will sort your problem out. Then adjust so you have a good gas flow. Also check out it isn't blocked too.

Vulcan Quasar wall furnace, pilot will lit and burner starts but goes out after a few minutes. sometimes pilot will relight but most often fails to light till unit cools down. Any suggestions?


You may need a new thermocouple if you have been able to light it before.It is located above the pilot lite and needs to get hot to keep the gas flowing.You can pick up a universal thermocouple a the local hard ware store.Shut the gas off,unscrew the coupling nut and remove the old one.Bend the the new one like the old one and replace.Try not to kink the new one.Good luck and thanks for choosing FixYa.com.

Pilot light won't stay lit


Look for dust and lint. Look for them in places where gas should be freely flowing. I had a similar problem with an Empire Corcho wall-mounted propane ceramic catalyst heater. First it was the pilot light, then the #2 ceramic mantle. After horsing around with the gas lines and pressure regulators and trying to re-aim the pilot, it all turned out to be dust and lint in the gas passages. A little dust bunny in the brass pilot tube gave me a pilot light the shape and color of a banana. One puff of compressed air, and I got back my razor-sharp pilot. And some dust in the chimney of the #2 burner kept it burning blue/yellow and blistering paint off the upper surfaces of the heater. A bit of cleaning with a shop-vac put that right. "Passive" heaters are very much prone to this sort of problem because they rely on convection currents (i.e. LOW velocity) to get the job done. Convection currents are notorious dust collectors, as in COBWEB CITY.
