Standard working pressure 30 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 I=B=R output ratings shown are based on
an allowance for piping and pickup of 1.15 (water) or 1.33 (steam). D.O.E.
capacity output is divided b
y 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 oper-
ation, 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 pages 11 and 12 of this manual are used, and
are properly adjusted to produce 13% CO

.

Nominal clay tile liner dimensions.
§ Water boiler models XL-30 and larger have two firing rates.The boiler is fac-
tory shipped at the lower firing rate.To obtain the higher firing rate, refer to
the XL-2000 boiler installation instructions for the appropriate field adjust-
ments
.“H” models have only one firing rate.

All dimensions subject to nor
mal 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.
