Overview of Primary Product
* Vent damper may be installed hori-
zontally on all models with use of a common vent elbow.
RATINGS FOR SENTINEL BOILERS – NATURAL AND L.P. GAS
* Net ratings are based on a piping and pick-up allowance of 1.15.
Slant/Fin should be consulted before selecting a boiler for installa-
tion 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 Sentinel boilers are tested and rated for capacity
under the U.S. Dept. of Energy (D.O.E.) Test Procedure for boilers.

DIMENSIONS
With five models ranging in size from 70,000 to 210 ,000 Btuh, Sentinel boilers meet a
wide range of residential and light commercial heating requirements. All models are avail-
able for use with natural gas or L.P. gas.
Sentinel boilers are “installer-friendly”, with features to make the contractor’s installation
and set up quicker and easier. All Slant/Fin boilers, for instance, are packaged in quick
release shipping crates to speed up unpacking. Boilers are factory-wired with quick con-
nect harnesses for the vent damper and blocked vent safety switch. Controls are all
mounted on the outside of the boiler for easy access and quick wiring. The boiler height,
including draft diverter, is up to a foot and a half lower than many natural draft boilers.
(For lower profile boilers with integral draft hoods, refer to the Slant/Fin Sentry models).
