new pilot light will not light

What is the trick or procedure to getting a standing pilot light to light?

The tech install the gas valve, it worked for three days. Now the pilot light is off.

Thanks in advance ...

pilot problem

sounds like a new gas valve, yet pilot problems. did he change the thermocouple? if not do it now, the old tcouple may not be supplying enough signal to hold in the new pilot valve. also be sure the pilot flame is positioned to sufficiently to heat the thermocouple, and that the pilot flame is not restricted.

The gas valve and the thermocouple and the pilot tube for standing pilot was installed as new.

Thanks for any advise ...

Was gas pressure set- if burners shut-off hard it can snuff out the pilot

gas pressure

To my knowlege gas pressure was not set. The techs came back and said the gas tube to the pilot was loose/leaking gas at the compression/thread connection.

Pilot is working again. I hope for good this time.

I had asked the first tech if any changes to the pressure reglator or anything else in relationship to the new valve had to be changed. Tech said no.

Good point, thanks ...

pressure settings

Manufacturers don't even want you to trust the setting. You should always set the gas pressure and adjust the pilot flame on ANY new install. It may be correct but you can't guess. Professionals never trust out of the box, the good ones anyway!
