What pressure is liquified petroleum gas fed to the burner?

Explanation:
Propane burners need a small, steady pressure to ensure the gas mixes properly with air and burns cleanly. In LPG systems, the regulator reduces the high cylinder pressure to about 11 inches of water column, which is roughly 0.4 psi. This low, stable pressure matches the burner jets and air flow so the flame stays steady and controllable across operating conditions. If the pressure were much higher, the flame would rise too large or flash back; if it were much lower, the flame could be weak or go out, especially as ambient conditions change. That’s why 11 inches water column is the standard feed pressure for LPG to the burner.
