    For single boiler applications, the firing rate controller is a L4006A. Set the L4006A firing rate controller for 175°F with a 5°F differential. On a call for heat, the burner will start in low fire and immediately go to high fire until reaching the 175°F setting of the L4006A firing rate controller.
