IMPORTANT: ANTIFREEZE ADDED TO WEATHERPROOF BOILERS MUST BE NON-TOXIC!!
(1) D.O.E. Heating capacity is indicated in thousands of Btu per hour. Use of antifreeze in any boiler can reduce capacity, net output and
efficiency by a significant amount.
(2) Net ratings are indicated in thousands of Btu per hour based on a piping and pickup allowance of 1.15.
(3) Annual Fuel Utilization Efficiency based on tests performed under U.S. Department of Energy standards and reported to the Federal
Trade Commission.
(4) Capacity greater than that requiring testing under F.T.C. regulations. Firing rates of 2.00 gph or less use a Beckett Model AFG oil
burner. Firing rates over 2.00 gph use a Beckett Model CF375 oil burner.
