* Heating capacity is based upon D.O.E. (Department of Energy) test procedures.
†
I=B=R ratings indicate the amount of equivalent direct radiation each boiler will produce under normal conditions and thermostatic control. Ratings based on an allowance of 1.15 in
accordance with the factors shown on the I=B=R Standard as published by The Hydronics Institute. Selection of boiler size should be based on “Net I=B=R Rating” being equal to or
greater than the calculated heat loss of the building.
**Based on 140,000 Btuh per hallon (10.8 kW per Liter)
***Annual Fuel Utilization Efficiency based on U.S. DOE test procedures and FTC labeling regulations.
Note: Due to Lennox’ ongoing commitment to quality, all specifications, ratings and dimensions are subject to change without notice.
