High efficiency, cast-iron oil-fired boiler

Your best choice for home heating comfort,
reliability and energy savings.

Intrepid is not just another oil-fired boiler. It is an upgraded
version of the Slant/Fin Liberty boiler, found in tens of
thousands of installations. It represents years of research
and development, aimed at producing a boiler that would
perform with efficiency and reliability, even during seasonal
extremes that threaten the performance of ordinary boilers.
Intrepid can reduce your fuel bills by up to 30% or more,
while providing years of dependable service. Intrepid is
constructed of durable, high-quality cast-iron and fitted with
the finest controls and components.

• High performance through computer aided design

• Cast-iron, wet base heat exchanger

• Expert workmanship. Reliable name-brand
components

• Hot water and steam models, with domestic hot water
coil option

• Installer-friendly features for installation and service

Advanced design ensures
superb performance, even
during extreme seasonal
operating conditions

The performance level of many
ordinary boilers is good follow­ing a tune-up, but it deteriorates
when operating conditions
change. The Intrepid boiler is
designed to protect against
adverse operating conditions.
The contoured shape of
Intrepid’s combustion chamber
is computer-designed to support stable combustion. The
uniquely configured heat exchanger has one of the lowest
draft losses in the industry. Burners are configured for each
specific model to provide smooth, clean, efficient operation.
These characteristics combine to ensure a robust flame that
is virtually unaffected by reduced draft, low oil temperature
or low air temperature.

The Intrepid boiler’s draft loss is less than .02" w.c.,
one of the lowest in the industry—important for
better performance and prolonged life.

Slant/Fin is a world leader in boiler-baseboard-radiant heating
systems for homes and commercial applications. Visit our website

In most boilers, the hot flue gases
which rise from the combustion
area must pass around the push
nipples that join the heating sec­tions. This results in uneven heat
transfer, concentrations of soot
buildup and undesirable draft loss.

Intrepid’s push nipples are located
to the side, out of the way of the
flue gases. This unobstructed flue
passage creates more uniform
heat transfer, minimizes draft loss
and reduces soot build-up.

Advanced design boiler
sections minimize soot
buildup.

The contour and spacing of ther­mal pins in Intrepid’s heat
exchanger turbulate flue gasses
and increase heat transfer surface
area. Superior heat transfer prop­erties permit use of smaller, com­pact heat exchanger sections that
generate more Btu’s per section
than ordinary boilers.
