Thread: Millivolt question.
07-06-2005, 10:44 PM #1
I'm working on a 250K btu pool heater. I use to have an old millivolt meter that told how low your reading could be and still hold in a 750 mv valve. The meter is long gone, I installed a new power pile and get around 590 to 600 mv when connected to the valve, but the pilot goes out when trying to energize the valve. I am going to change the valve, how low can the mv's be and still hold the valve in?
Been awhile since I've done a millivolt system. Thanks.
