Slant/Fin should be consultod boforo solocting a boiler for installation having unusual piping and pick-up requirements. Ratings must be reduced by 4% at 2,000 feet elevation and an additional 4% for every additional 1,000 feet elevation over 2.000 feet. Add suffix "S" for standard water boller, "p" for packaged water boiler. Add suffix "E" for intermittent pilot ignition system (available only with 24 volt gas vaive). Type of gas: After model number, specify gas by name "Natural," or "Propane."
