Question about Heaters
Hi, problem is when depressing the "control" knob and sparking the center ceramic lights but even when holding down for +- 10 mmins and slowly releasing the gas control knob the fire dies, it has always worked in the past even if a bit temperamental ! Pls hrlp, Thanks

You need to bled the line longer and when you get lited hold down for a good minute.When the gas gave out ,there could trash in the line.I would take the line off and blow gas through it undtil you can smell it.

sometime if the heater has been sitting for days spiders get into the burner area or the area between the tank and the burner and make a web blocking the flow. I have taken a compressed air in a can like the ones you use for computers laptops and blow air up the shaft and around the burner wait 2 minutes then try again. Sometimes it takes 2 or 3 blowouts to work.

Holding the button down enables gas to go to the pilot. When it lights you will see the flame touching two rod like devices. The small one is the igniter. The second one is a thermocouple. A thermocouple is a bimetalic device (2 disimilar metals) that when heated produce a small curren, this current in turns keeps the valve open for the gas to flow when you let go of the button. This is a safety feature. If the flame goes out on the pilot the thermocouiple cools and closed the valve shutting off the gas so you don't go boom! It sounds like the thermocouiple is bad or missaligned. If it is missaligned it will take longer to get hot enough to hold the valve open. Another thought would be the flame is not shooting out far enough (not enough gas pressure, clogged oriface on pilot(previous writer, leak but you get the idea. In my manual it had a picture of how the flame should look hitting the thermocouple. Good luck. My problem is I assumed that the regulator on my construction heater was the correct size. Maybe not. I have not had any luck getting the pilot to light at all. I hope I have not damaged the internal regulator.

SOURCE: Torpedo heater wont stay lit.
Do you have the serial number or the manufacture date? There are some design changes and I would need to know the year of manufacture to assist accurately. Usually it is a relay or the thermocouple connection that will affect the unit staying lit.

The thermocouple [s] require replacement, or in my experience try servicing the unit first. There is an injector for the main pilot and a secondary injector for the flame thrower ignition. Both of these are prone to blocking due to dust and can be enough to shut the unit down. Although usually this is thermocouple related as you are manually keeping the unit running when you hold down the button, if the tcouple is broken it wont send enough millivolts to hold the magnetic valve open when you release the button.

Before you go changing parts, clean up the pilot assembly. When you heat metal and let it cool and heat it again it causes it to corrode. Also for some reason these areas seem to attract little spiders who make their homes here. This causes gas flow problems which in turn could affect the size and direction the pilot flame. For if it does not touch the thermocouple, thermopile or whatever that little thingy is called that tells the gas valve to allow the gas to flow...it will not tell the gas valvle to let it flow. Remove the corrosion, spiders, spider webs and any other insects then sand the thermocouple, thermopile or whatever that little thingy is with a rough sandpaper to remove corrosion. It will likely work after that.
I maintain six similar heaters for a restaurant in Charlotte, NC. Rust and bugs seems to be what gets them every time.
