3 Combines world class design and workmanship with unequaled Eutectic cast iron performance. Up to 87% efficiency. Functions at lower operating temperatures. The EC Series efficiency is a result of the boiler s unique three pass Eutectic cast iron heat exchanger. It utilizes specially designed baffles to increase flue turbulation, maximizing heat transfer. This helps achieve AFUE ratings of up to 87%! The EC Series boilers have a unique cast iron Eutectic heat exchanger that is resistant to thermal shock and corrosion. The castings are made from molten iron blended with elements and minerals that make it both flexible and durable. This means they can intermittantly operate at lower operating temperatures especially suited for outdoor reset controls. This improves overall heating system efficiency and yields significant additional energy savings. The three pass design, along with 4 inches of insulation, make them the quietest boilers in their class. The Eutectic heat exchanger has plenty of room for thermal expansion of the flue gasses to keep the flame noise to a minimum. Combine this with one last turn before the flue gasses exit the boiler and you get whisper quiet operation. The Eutectic Series boilers, like other Slant/Fin boilers, will operate cleanly and quietly under various operating conditions and combinations of cold or warm oil and cold or warm air. We ve done the testing and have optimized burners, components and baffles to make sure the boilers will stay running clean. Features: Up to 87% AFUE Resistant to thermal shock and corrosion Improves overall heating system efficiency Three pass Eutectic heat exchanger maximizes heat transfer Hinged, reversible swing out door and removable baffles for fast, easy service Available with Beckett, Carlin EZ 1 Pro, and Riello burners Lifetime limited warranty Direct Vent models available for installations without chimneys Extremely quiet

4 EUTECTIC SERIES Superior cast-iron, three pass, oil-fired boilers Good looks and more. The beauty of the Eutectic Series boilers goes beyond their good looks. With up to 87% AFUE, dramatic energy savings and extremely quiet performance, they can be installed almost anywhere. The Outback Connection All piping connections are made at the rear of the boilers to keep installation looking neat. Supply and return connections, drain valve and cast iron flue connector are located here. Flue outlet on the EC-10 series is only " off the floor, low enough for the lowest of chimney breechings. Annual cleaning is easy Access to boiler flueways is from the front. Unbolt door and swing open for full access to heat exchanger. Wide open flueways for easy brushing of entire heat exchanger. No place for dirt to hide. Bolted shut door ensures positive seal. Clean-out door is reversible from left hinge to right. Easily accomplished by removing two screws and loosening two nuts to transfer hinge to opposite side without loosening door from boiler. Metal Push-nipples Cast Iron sections are joined together using only metal push nipples that expand and contract with the individual boiler sections they connect. Rubber gaskets that are sometimes substituted for push nipples in other boilers frequently deteriorate and cause leaks and major repair bills. Metal push nipples have been proven for over one hundred years. Abundant hot water too. Eutectic can provide plenty of hot water for your kitchen, bath and laundry year round when connected to a high efficiency indirect water heater. The luxuriously cozy comfort of baseboard heating Slant/Fin is America s number one brand of baseboard heating too. Whether modernizing or building new, you can count on the comfort, style and quality Slant/Fin is famous for including Fine/Line 30 and Multi/Pak 80 rust-resistant baseboards. Spread the warmth with wall to wall comfort, blanking out drafts and cold spots. Your home is too important for ordinary heating, it deserves Slant/Fin quality.

5 3 PASS DESIGN The Three pass design is what makes the boiler extremely quiet and efficient. Popular in large commercial boilers, this design maximizes heat transfer, increases efficiency due to increased surface area that the flue gasses come in contact with and keeps it there longer. This results in low stack temperatures indicating high efficiency. There is at least 6 lineal feet and at least 11 square feet of surface area to ensure generous heat transfer. A.F.U.E. is 87%. The extra room in the boiler passageways provides for thermal expansion of the flue gasses making this boiler extremely quiet. COMBUSTION CHAMBER Direct heat transfer to Eutectic iron without refractory chambers or target wall. The 2000 degree boiler flame heats boiler walls quickly, transfers energy to boiler water unimpeded by insulation. Tightly sealed chamber and sections allows positive overfire pressure, further ensuring maximum heat transfer. Minimal draft loss through boiler makes venting through chimney easy. CONTROL PANEL Houses Honeywell aquastat and tridicato r control or optional energy saving SF-10 control SIGHT GLASS VIEW PORT BUILT-IN LEVELING LEGS For easy installation on uneven sufaces. BAFFLE PLATES Removable for easy cleaning of boiler sections, baffle plates help turbulate flue gasses ensuring homogenized flue gas temperatures on boiler heat exchanger walls maximizing heat transfer into boiler water. OIL BURNERS Riello, Carlin EZ Pro and Beckett models provide clean, reliable, efficient combustion under all operating conditions. The burner for each Eutectic boiler is optimized and custom manufactured to Slant/Fin specifications. Burners provide high static pressure for positive chamber pressure. Every burner is adjusted for peak performance but final minor adjustments are easily made by the installer. Riello comes with blue burner cover for additional good looks and quietness. WATER CHANNELS When boiler is operating at low water temperatures, water condensation could form on the heat exchanger. These specially integrated channels direct water flow to combustion chamber where it is burned off. The formation of condensation is allowed to occur periodically when the outdoor reset control operates boiler at low temperatures.

6 FOR DELUXE ENERGY EFFICIENT CONTROL OF YOUR HEATING SYSTEM AND EUTECTIC SERIES BOILER Optional Model SF-10 Control Easy to set. Wizard-like total system management and boiler control. Provides greater comfort and utmost in fuel conservation. Reduces cycling, adjusts system water temperature based on outdoor temperature. Provides heat from low temperature water, improving efficiency using lower temperature flue gasses. OPTIONAL MODEL SF-10 CONTROL PANEL PROGRAMMABLE CONTROL Controls boiler water temperature based on outdoor temperature with or without influence of room temperature from the room sensor. The programmable reset curve automatically adjusts itself by learning how much the temperature in the room is affected. MAXIMIZES THE EFFICIENCY OF THE BOILER AND HEATING SYSTEM To maximize system efficiency while improving comfort, the system circulator stays on while the control modulates the water temperature by intermittently firing the burner. This means that the boiler s input and the BTUH input into the room (controlled by the water temperature) actually matches the heat loss. Temperature swings in the living space are eliminated, as when keeping a pot simmering on a stove, you adjust the heat to keep it just right without STANDARD CONTROL PANEL Includes on-off switch, indicator lights and tridicator. Behind panel is the traditional Honeywell L7248L.

7 boiling over. With the Model SF-10 Control regulating the heat, it is always on but at reduced water temperatures. Drafts and cold spots are virtually eliminated. With baseboard heating along the outside walls, a warm blanket of air is constantly insulating the occupants from radiating their body heat to the cold walls and windows, which would make them feel chilly. No chimney? No problem. EC-10 series boilers (up to 161MBH) can be vented directly to outdoors with flexible vent piping. No need to build a chimney in new construction or re-line poor chimneys on replacement jobs. Good air in, bad air out. REGULATES DOMESTIC HOT WATER PRODUCTION Takes into consideration the outdoor temperature and decides when to interrupt the hot water priority to make heat. It does not limit the DHW priority to a timed cycle. SYSTEM INFORMATION Control panel has digital readouts of boiler water temperature, outdoor temperature and domestic hot water temperature. RESET HIGH LIMIT The control has a safety boiler water temperature high limit with auto reset. Concentric vent terminal takes combustion air in through outer ring, gets heated slightly by the exhaust air in the inner ring and insulates the exhaust from building construction. This ingenious device means there is only one opening through the wall. For direct vent applications specify direct vent kit and burner.
