How do I turn the pilot off on my boiler - Heating & Cooling

It is no flame detected. if gas meter was changed boiler should have been turned off . If this was not the case you have air in the boiler line which is try to purge out by the pilot which is a very small hole so this would take for ever .

Turn boiler of to try and reset it or you will have to purge boiler gas line .in the 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.

Power can be on just turn the room thermostat down .

Turn the gas valve to pilot. Push knob down & hold. While holding, light pilot & keep knob held down for one minute. Let go of knob & see if pilot stays lit. then turn knob to on position. Boiler should then turn on.

TURN WATER OFF TO UNIT AND ALL POWER AND GAS. EXTRACT ALL WATER AND REPAIR PLUMBING TO THE BOILER. IF WATER
IS COMING OUT FROM THE BOTTOM, REPLACE BOILER...
IF PLUMBING WAS REPAIRED SUFFICIENTLY AND NO WATER IS PRESENT...TURN ON WATER AND CHECK FOR LEAKS THEN TURN ON ALL POWER AND GAS TO THE UNIT AND RELIGHT
PILOT....BE SURE THERE IS NO SMELL OF GAS PRESENT WHEN YOU LTE THE PILOT..IF IT DOESN'T LITE YOU MAY HAVE TO REPLACE THERMOCOUPLE OR CLEAN BURNER.

Hi - hope someone can help. I have a VOKERA EXCEL 80SP combi boiler and been without hot water/central heating for two days. The pilot light is on, the fan is on, but boiler not triggering once the hot water tap is turned on.
Hopefully someone come to look at it today but hoping for some advice. Anyone else had this problem?
Thank you.

Check the gas valve on the boiler. See if it is on the "pilot" setting. Sounds like it is....if so, turn to "on"

if your boiler is a combi re-pressurise locate filling loop and refere to manual

it also sounds as though the pilot injector could be blocked so when the boiler comes on it extinguishes the pilot & then when the burner goes off boiler shuts down, or also the pilot rate maynot be set right, so when the main burner kicks in it robs the pilot of the gas it requires.
It could be that, or there is lack of ventilation for the boiler, so you get flame lift off when the boiler fires?

TAKE A SHPO VAC AND CLEAN AREA. MAKE SURE YOU PAY SPECIAL ATT. TO THE PILOT LIGHT. FIND BUTTON HOLD IN AND IGNITE DONT LET GO WHEN IT LIGHTS FOR AT LEAST FIFTEEN SEC.. YOU MIGHT ALSO HAVE TO TURN THE THERMASTAT OR KNOB TO PILOT FIRST. AFTER IT HAS LIT TURN UP FLAME
