Is the field control actuator pn 46491600 a direct replacement for a Weil McClain vent damper model RVGP-PC-5 installed on a CGA4 gas boiler? The part number for the old unit is 510-512-345. I’m Looking to replace the damper actuator only, not the entire unit. Thanks in advance.

Yes, if the existing system is standing pilot and is wired as shown.
