I have the same problem with our gas heater (Pyrox 625 - over 20 years old) not
staying on even after holding down the red ignition button for over 20 minutes
(!) It got gradually worse over time till now it never stays on.
This might be a silly question but is it necessary to turn off the gas to the
heater before replacing the thermocouple?
