How to relight pilot on boiler

Every boiler will have manufacturer lighting instructions on the unit, so be sure to read it thoroughly and turn off the gas for 5 min to make sure there is no gas build-up around the boiler. Some have electronic ignition and some require a manual lighting of the pilot. If the control knob has only ON-OFF, it has electronic ignition. Simply turn off the power (at the electric switch on the boiler or at the breaker box) and then turn it back on and it will relight itself when heat is needed) If it has ON-OFF-PILOT, you will have to light it manually. You will have to turn the gas valve knob so the arrow is pointing at the word "pilot" and depress the knob, while lighting the pilot with a lighter or match. Continue to hold the knob down after the pilot is lit for about 30-45 seconds to allow the thermocouple to heat up. If you release the pilot knob and the pilot stays lit, you can turn the knob to the "ON" position and the burner will light. Please be careful. if you are not sure what you are doing, call a professional.

My mr heater wont stay light unless its above 3. It only stays on about 5 min then pilot goes out. It is gas heater. What's wrong with my heater?

Theres a thermostat inside, if its too cold and not warming up the thermostat enough it will shut off because it thinks there is a problem.

How do i light pilot light?

Remove front cover,or just lower section if you can. they usually just need to be lifted up about an inch or so and pulled out. However some have covers that snap in place. After you remove cover locate gas valve. It should have a control knob on top with markings for on, off, and pilot. Set control to pilot. Follow lines from gas valve to burner compartment, one goes to main burner one ,small copper colored line is the thermocouple, other line is the pilot. Turn thermostat down as far as it will go. Make sure gas supply valve in line to heater is on and then depress pilot control , when you have pilot control depressed have a match or other small flame source close to pilot assembly. If it lights then hold down on pilot control for a couple of mins. Slowly release pilot control and if it stays lit turn gas control to on. Turn thermostat up to call for heat and burner should light. If pilot doesn't stay lit when you release pilot control then try again holding pilot down longer. If it still won't stay lit then thermocouple will need replace. Good luck. Thanks

I have Dayton space heater 3E 229, pilot wont stay on,I have install new gas operating valve and checked transformer ( 30V) . Pilot lights up but wont stay on even if I hold button down for 2-3 min. please...

The thermocouple is likely defective...(Copper wire heated by the pilot) or the pilot itself is too small or dirty....the pilot must be BLUE , not yellow like a candle...and it must envelop the top portion of the could also have an auxiliary limit or ECO wired in series with the thermocouple circuit that could be open.....also make sure the thermocouple is inserted all the way and is in the pilot flame as mentioned above
