Munchkin with 925 control

Is there an outdoor reset option for an 80M?  I have a customer with an existing unit, bought used.  It has the 925 control.  After looking through an old service manual, I have not found any info. 



This boiler has also been sitting idle for about a year.  I haven't done a hydro test on it yet, I am considering doing it before piping.  Think any of the gaskets or ceramic target/refractory will need replaced.  It would be nice to change out before boiler is set.

There was an error rendering this rich post.

    Munchkin 925 Controll ODR

    I attached a wiring diagram that may prove usefull.  It came from Chuck Shaw formerly of HTP.  It is to add ODR to the older model 925 controll boards.  Also gives dual temp for indierct water heater.
