Computer-aided design.
Highest quality manufacturing.
Superior components.
Advanced design heat exchanger with metal push
nipples provides superior performance, longer life.
Computer-aided design of heat exchanger maximizes transfer of
heat from the gas flame to the boiler water which then flows into
your heating system. Superior heat transfer properties permit use of
smaller, compact cast-iron heat exchanger sections. The flue pas-
sage design, thermal pin pattern and consistent wall thickness
ensure uniform heat transfer with less thermal strain and metal
fatigue.
Metal push nipples avoid leaks.
Slant/Fin uses only metal push nipples that expand and contract
with the individual boiler sections that they connect. In many ordi-
nary boilers, flimsy rubber or plastic gaskets are substituted for
metal push nipples and are subject to deterioration and leaks.
Reliable heavy-duty vent damper saves energy.
The motorized Slant/Fin vent damper increases efficiency of the
boiler by reducing standby losses. Motor closes the chimney vent
when the burner is off, fully opens it in anticipation of combustion.
May be installed horizontally or vertically to accommodate varying
vent pipe requirements. Heavy-duty collar maintains dimensional
stability for smooth operation.
Vent damper shown on “S” model.
Insulated base
Base is constructed of heavy gauge aluminized steel. Thick refracto-
ry insulation surrounds combustion chamber, minimizing standby
losses and increasing efficiency.
Long-life burners
Quiet, light and easy to install or remove. Same stainless steel
burners serve natural or propane gas. Special port construction will
not permit flame to “lift” or flash back. Sentry burners last longer too
because of low operating temperature. Input per burner is only
15,000 Btu/hr.
