Pilot light works fine but regardless of how long I hold down the light pilot light button, when I try and move the control to ON, the pilot light decreases then goes out and the heater does not light. I have installed a new regulator on my propane tank but that did not help.

Re: Heater won't light
YOU HAVE A BAD THERMOCOUPLE. IF YOU LOOK AT THE FLAME you should see a little match size piece of gold metel connected to a metal tube like then screwed into the gas valve. what happens is when you light the pilot, the gas heats up one end of the thermocouple and the other end changes that heat into microvoltage. the gas valve senses the microvoltage , knows the pilot light is lit then opens the main gas valve. when they go bad they cant send voltage to valve and th valve locks out. you always have to start at off. then depress valve button and turn to pilot and light it. hold button down 3 minutes then turn to full open or main the thermocouples are cheap, call supply houses or service companoies till you find one that will sell you one. unscrew the thermo couple from the valve with a little wrench unwravel the excess tubing , size of a pencil lead in diametor, then the probe part usually slids up through a spring like holder, note position of old sensor before reoming. get end half of new sensor into good pilot flame. reuae old retainers or new ones that come with new t couple.

Gas is turned on? Pilot button is in pilot position? Push and hold pilot button down, keep holding it down, push igniter many times, while keep holding down pilot button, keep holding until pilot lights. May take several minutes.
Turn the Gas Control Knob inside the heater compartment from OFF to PILOT. Push in the knob and hold it, at the sametime push the ignitor button (will probably be a Red button). Once the pilot lights, continue to hold the Control Knob down for one minute. Then ease off of it. If the pilot stays lit, turn the Control Knob to the ON position. The burner should light, if the Thermostat is set higher than the ambient temperature in the house. If the Ignitor button doesn't work, you can match light the pilot. Just be careful and follow the instructions above, once it's lit.
Move the gas valve knob to the PILOT position and press down on the knob. You will be pressing down on a spring loaded safety magnet. Now light the pilot and keep holding down the knob till the thermocouple gets hot enough to produce electrical current and hold that spring loaded magnet in. This is your safety device. If the heat gets too hot the furnace has a fuse in line with that magnet. When the pilot stays lit by itself without you having to hold down the button then advance the knob to the ON position. Then go to the wall thermostat and turn on the heater.
The question is? I'll assume you cylinder is the water heater, right?
On the heater (water) you will find or see the red controls and a sheet metal cover over a hole. Remove the cover and this is where you light the pilot light. Press down on the red dial and turn it to pilot. In that position you will be able to press the red button . Geyt a long match or bbq lighter, then, holding down the red button dow for a minute or so and place a match or lighter into yhe area where the lines go The flame will catch the gas and lite the pilot if yo simply move your glame around. When the flame catch on the pilot, continue holding the button down for sveral minutes until the buld the flame isheating gets hot. Then release the buton and turn the main dial to on. The main burner should fire up. If not, and the pilot goes out, repeat the process. The bulb in the pilot flame is a thermocoupler that shuts all gas off if it doesn't detect a pilot flame, so hold the button down longer. If the pilot goes out when you release the button, The thermocoupler is no good and needs replacing. Good Luck_Ned_
Try this, turn the black gas ****, on top of the control box, to the Pilot position. Set the temp. control on the front of the box to the desired temp. Then, hold a match or whatever else you use to light it, next to the end of the pilot, then, while holding the match to the pilot, press the reset button on top. When the pilot lights, continue to hold the reset button down for about 1 minute. Then, after a minute, turn the gas **** to the ON position, then it should remain on.
You pilot ignator is plugged.I take a small wire and run it in the hole every year and I also Blow the heaters out real well with air.THis has always worked far me.I need a phone number or email address to Pro Com because i'm having problems with a new one i just bought and I can't find the papework.Could you pleas eif you have this info email it to me
On these older gas water heaters there is a gas control with temperature selection and below that is a removable cover. Once you remove the cover you can gain access to the pilot. You must rotate the knob on the top of the control to the pilot position. When in the pilot position, hold the red button down and light the pilot. Continue to hold the button down after the pilot is lit for about one minute. If when you release the red button the pilot goes out, try one more time. If it goes out again after releasing the button your thermocouple is bad and must be replaced. The thermocouple generates a millivolt electrical current that hold the gas valve in the operating condition when the pilot is lit. When the pilot goes out there is no heat to generate this small electrical field.
