* Net ratings are based on a piping and pick-up allowance of 1.15. Slant/Fin
should be consulted before selecting 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.
†Type of gas: after model number, specify gas by name “Natural” or
“Propane”.
Note: All Sentry boilers are tested and rated for capacity under the U.S.
Dept. of Energy (D.O.E.) Test Procedure for boilers.
