Weil Mclain with Indirect Mega-Stor

Jack_33 Member Posts: 19
Have proposal in hand for replacing 60 year old steam boiler.

Looking at the Weil Mclain #PSGO-4 with Riello burner and Mega-Stor 40 gallon indirect water heater as the replacement boiler and water heater.


With respect to Riello burner, suggestion on oriffice size would help?

    Don't see any issues with your proposed installation. We use this set up all the time but with the Weil PLUS tanks.

    AS to orifice size, install the correct orifice for the max. firing rating of the boiler. Simple enough?
