High performance, cast-iron gas boiler

with Lifetime Limited Warranty

The smarter choice for

informed homeowners.

Enjoy home heating comfort with the extra

confidence that an advanced design Sentinel

boiler provides. The Sentinel boiler combines

the reliability of natural draft and cast-iron con-

struction with the high efficiency performance

provided by the Slant/Fin S-Series heat

exchanger. A new Sentinel boiler can save 30%

or more on fuel bills compared to a typical old

oiler operating at 60% efficiency.

Reliable natural draft design

When the Sentinel boiler is operating, combus-

tion air enters the boiler and exhaust is expelled

up the chimney by natural draft. No mechanical

combustion aids are required for the boiler to

attain its high efficiency.

High performance heating

The Sentinel boiler’s S-Series heat exchanger is

made of quality cast-iron and assembled with

durabl

e metal push nipples. Specially shaped

thermal pins promote efficient heat transfer. The

boiler heats quickly, sending warmth to radiators

throughout your home within moments of your

thermostat’s call for heat. The Sentinel boiler is

so reliable it comes with a lifetime limited

warranty.
