Question about Heating & Cooling
My ageing Vulcan Quasar 40 gas wall heater stopped working yesterday - the pilot light went out. When I try relighting it, it goes out as soon as I release the button.
I have tried turning power off at the mains, waiting 15 mins and starting the process again, but the pilot still 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.

Try cleaning the thermal couple. Just remove the ash from around it. If that doesn't work you will have to change out the thermal couple.
