can i install a mynchkin type boiler on an all cast iron heating system

[Deleted User]

I would like to know if it is possible and worth the cost and efficiency to install a condensing boiler like the munchkin on an all cast system.What do I need to make sure it is done to make it operate correctly and for a long time?I've been told I will need to make sure the system has primary secondary pumping and im not sure how to know if this is done and done correctly. The system now is a cast iron burnham boiler with a chimney lock and the main header is 3 inch cast iron piping with 1  1/2 copper for the at boiler connections with a b&g series 100 on the return. Thank you for any and all help or comments
