Maximum operating pressure 60 psi.
All boilers hydrostatically tested — A.S.M.E.
* For forced hot water heating systems where the boiler and all piping are
located within the area to be heated, the boiler may be selected on the basis
of D.O.E. capacity output. The net AHRI output ratings shown are based on
an allowance for piping and pickup of 1.15 (water). D.O.E. capacity output is
divided by the allowance to obtain net rating. The Slant/Fin Technical Service
department should be consulted before selecting a boiler for unusual piping
and pickup requirements such as intermittent system operation, extensive
piping, etc.

† Ratings apply to the use of light oil at 140,000 Btu per gallon and apply only
when burner models listed on page 12 of this manual are used, and are
properly adjusted to produce 13% CO 2 .
# All dimensions subject to normal manufacturing tolerance.
NOTE: All boilers under 300,000 Btuh (87.9 kw) input are tested and rated for
capacity under the U.S. Department of Energy (D.O.E.) Test Procedures for
Boilers.
