This top-mounted collector box interfaces directly between the heat exchanger and the draft inducer motor
This motor typically requires a 3 MFD / 370V run capacitor
it monitors high-side pressures from 10-50" W
the 906-13DRW is specifically a remote-sensing model that includes the necessary 10K duct probe and a visible setpoint adjustment on the main thermostat base
Can I use this for other boiler series
