Hi guys:

I have a CG-6 gas boiler and it needs a vent damper. The guy at my supply house who can be helpfull but can also be an idiot gave me one for a Crown (6" FLUE) and says they are interchangeable. I seem to think they are, as there is only one way to plug the harness in (I THINK) and therfore the wiring will match up fine.

I just want to confirm the above before I proceed.

    If they were actually made by Effikal or Field

    they are interchangeable. Field bought Effikal some time ago.

    But if only the motor is bad, you can replace just the motor. I think the Field part# is GVD-RMA.
