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 for more product and application information.

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.
The best components, plus expert Slant/Fin workmanship and integrity, create incomparable dependability.
There’s no better built oil-fired boiler than Intrepid. Every compo­nent we use in the Intrepid boiler is of the highest quality. Heat exchanger sections, for example, are made of only the finest cast iron, finished to exact specifications on automated high precision machining centers. Final assembly of each boiler is performed by hand. Multiple checks are made for quality and overall boiler integrity. Every boiler section, for instance, is tested under pressure at least 8 times the normal residential operating pressure. Repetitive testing -- individual sections, assembled heat exchanger and completed boiler -- ensure the leak-free integrity of every boiler shipped.
Burner performance optimized for each specific model. Every burner factory tested.
The Intrepid boiler is equipped with an advanced design Beckett, Carlin, or optional Heatwise or Riello oil burner. The burner for each Intrepid boiler is custom manufactured to Slant/Fin specifi­cations. It is engineered for each specific model to provide smooth, clean, efficient operation under all job conditions. The flame is up to 200°F hotter and up to 35% more efficient than older non-retention head burners.
For reliability, every burner is factory tested before shipping. It’s given a full combustion test and fine tuned for optimal perform­ance on the specific size boiler it is mounted on. Final adjust­ments are easily made by the installer, if necessary, based on the unique chimney draft conditions of each individual house.
For dependability, metal push nipples; name brand controls and circulator pump
Slant/Fin uses only metal push nipples that expand and contract with the individual boiler sections that they connect. The rubber gaskets that are substituted for push nipples in many other boil­ers could deteriorate. This could result in water leaking from the boiler and major repair bills. Dependable performance is further ensured with nationally known brands of controls and circulator pumps. All controls are mounted and fully wired. Steam models include float type or electronic low water cut-off.
Lifetime limited warranty. The Intrepid boiler is engineered and built for a long, dependable life. Hot water models are covered under Slant/Fin’s lifetime limited warranty. Steam models have a limited ten-year warranty. Contact Slant/Fin for details.
Extended hot water heater coil performs better.
Metal push nipples outperform rubber gaskets.

Installation is faster, service is easier with these special Intrepid features.
Your Slant/Fin heating contractor can usually install a new Intrepid boiler in about a day. Its compact size and removable burner door allows it to fit through doors and stairwells with ease. A strong wooden crate protects the Intrepid from factory to basement. Its low profile, only 32 inches high, simplifies installation. Packaged models come pre-wired with the burner mounted, ready for final setup. Controls are mounted up front for easy access. The circulator is prewired and bolted to the skid for shipping. Wiring is long enough for supply side or return mounting. For your convenience, all models include front and rear return tappings. All tappings are sized and positioned to give the installer flexibility in connecting the Intrepid boiler to your heating
system.
Burner door swings open, lifts off
Intrepid’s extra large door swings open for routine servicing. It also lifts
off, making it easy to fit the boiler through tight spaces and down stairs.
For added safety, a disconnect plug automatically cuts power to the
burner when the door is opened.
A generous 3" supply tapping on steam models helps produce drier steam, resulting in quieter operation of your steam heating system.
No furnace cement is required with Intrepid’s speedy-service flue collector. Can be quickly and repeatedly removed and pressed back into place in a channel containing a replaceable sealing strip. No furnace cement required. Flue collector locks positively tight with a single wing nut. Reduces cleaning time dramatically.
Front mounted service switch makes servicing convenient.
Top cleanout is easy.
With the flue collector removed, it's easy to reach all of the heat
exchanger surfaces with a flue brush for routine cleaning. Since the
refractory wall is recessed, it is protected from damage by the flue brush
during cleaning.The spacing between Intrepid's section walls and the
arrangement of thermal pins permit fast effective cleaning.
Easy access, higher output tankless heater coil.
Tankless cover plate is mounted on cast-iron extended flange which protrudes 2 inches through front of boiler jacket. Provides constant visibility for easy inspection. Out-in-front bolts permit easy removal of seal or coil. Deeper well accommodates longer coil to maximize output of domestic hot water.
Long-life stainless steel cap nuts.
Ordinary bolts in the domestic hot water cover plate can deteriorate in
time and make routine maintenance a major repair should the bolt
heads snap off. The stainless steel studs and cap nuts used on
Intrepid’s tankless water heater resist corrosion, helping to keep long
term maintenance costs to a minimum.
Intrepid steam boiler
Intrepid can provide hot water all year long for your kitchen, bath and laundry.
Optional high output tankless heater. This coil type “instant” hot water
maker is located inside the boiler where the constant flow of hot boiler water heats your fresh water as it passes through the coil. Intrepid’s extended coil well accom­modates a larger coil to maximize output. Recovery is fast and the total capacity will vary with the boiler size.
Indirect water heaters. If you prefer to have a larger reserve of hot water, your installer can provide a hot
water storage tank that is easily connected to the Intrepid boiler. These tanks typically store between 20 and 60 gallons of hot water. Some require the boiler’s tankless heater coil to make hot water. Others have built­in heating coils which are connected to your boiler in the same fashion as a heating zone.Your heating contractor can recom­mend which domestic hot water system is best for your needs.
Zone your heating system for even greater fuel savings.
By dividing your home into separate heating zones, you can save energy by heating only those areas you’re using. Depending on your existing piping arrangement, it may be quite simple to zone your system. An auxiliary return tapping on the Intrepid boiler gives the heating installer added flexibility in setting up two or more heating zones in your home.
