Euler: A baby on his lap, a cat on his back thats how he wrote his immortal works (origin?). If it fires, it is working correctly. Wait five minutes to allow any gas in the combustion chamber to vent. Check the regulator setting either with a manometer or by clocking the gas meter. The second automatic valve operator is de- energized, closing the channel to the pressure regulator, and opening a channel to the underside of the second automatic valve diaphragm. This diverts gas flow from the automatic valve diaphragm and causes a reduction of pressure on the underside of this diaphragm. 0000004941 00000 n Apply a moderate amount of good quality pipe compound (Do not use Teflon tape) to pipe only, leaving two end threads bare.
