This is the Burnham Revolution that added a heat reclaimer to boost its efficiency. Model # may be RV3NSl-22. I will pay for a copy on the I and O manual. Contact me at timmcelwain@gastcri.com

    Thanks ethicalpaul I have that manual. The one I am looking for is the one that was converted to a modulating boiler.
