Maxitrol 325-5L600-1-LIM Regulator Els PW 29614 the H-221 and H221 are

the H-221 and H221 are identical part numbers and represent the same technical specifications and form factor

ensuring a seamless shift between the 15 psig nominal day and 20 psig nominal night supply pressures

Operational Safety: Prevents hazardous operation by ensuring positive or negative pressure thresholds are met before the gas valve is energized

Technicians often source this 2940-3571 sequencer when troubleshooting elements that remain energized after the thermostat is satisfied or fail to engage during the heating cycle

this assembly integrates seamlessly with 1/4 inch pilot tubing for airtight gas connections and consistent burner ignition

Maxitrol 325-5L600-1-LIM Regulator Els PW 29614 the H-221 and H221 areThe Maxitrol 325 5L600 1 LIM is a high performance 1" NPT gas regulator designed for rigorous line pressure applications. Engineered as a lever acting design with OPD (Over Pressure Device), this ANSI Z21. 80 CSA 6. 22 certified valve serves as a critical 2 PSI or 5 PSI piping system interface, reducing upstream pressure to safe operating levels for downstream equipment. It handles 5 PSI max inlet pressure for Natural Gas and 2 PSI max inlet pressure
