Every boiler relies on a few key pressure controls to stay safe and operate efficiently: • Firing Rate Control – Modulates the burner for steady operation. • Operating Pressure Control – Stops and restarts the boiler at set pressures. • High Limit Control – A manual reset backup for added safety. • Low Fire Hold – Keeps the boiler in low fire until safe pressure is reached. Together, these controls keep your boiler running safely and smoothly. | WARE
