The High-Efficiency, High-Output Compact Water Heater
What's more, unit inputs range as high as 1,300,000 Btu/hr but require just 4.6 sq. ft. of floor space. Only the Power-Fin-with its high efficiency output-can offer such heavyweight performance in a water heater so compact. Plus, with new venting capabilities, the Power-Fin is even more flexible in installation. And it is easy to see how the Power-Fin is performing thanks to a new digital control panel.
Outstanding Thermal Efficiency
Power-Fin water heaters offer up to 87% thermal efficiency and a NOx rating of less than 30 ppm by way of fan-assisted sealed combustion. This means that 87¢ out of every fuel dollar goes into heating the water - dramatically reducing operating costs of the water heater while ensuring clean combustion.
The heat energy from the combustion process is transferred to the water as it passes through the solid copper finned tube heat exchanger. The sealed combustion design eliminates external heat losses, which means that the fuel dollars are used to heat the water, not the mechanical room. It also ensures the jacket stays cooler, providing greater safety and requiring less clearance from combustibles
- zero clearance on each side.
First Power-Fin production model - 1986
DirectAire Vertical w/ Sidewall Inlet*
Vents vertically up to 50 equivalent feet, and directly draws combustion air 50 equivalent feet from a side wall.
Vertical
Vents vertically through the roof.
Sidewall*
Vents horizontally up to 50 equivalent feet, using Category IV approved vent material.
Direct Vent Horizontal*
Vents horizontally up to 50 equivalent feet, using Category IV approved vent material. Directly draws combustion air 50 equivalent feet from a side wall.
Direct Vent Vertical
Vents vertically up to 50 equivalent feet, and directly draws combustion air 50 equivalent feet from the roof top.
DirectAire Horizontal w/ Rooftop Inlet*
Vents horizontally up to 50 equivalent feet, using Category IV approved vent material. Directly draws combustion air 50 equivalent feet from the roof top.
Power-Fin Venting Options
These new models also feature a more flexible two pipe, independent air inlet and exhaust vent piping. When equipped with On/Off firing controls the Power-Fin utilizes Category I, Type B vent material in most cases. When equipped with modulating fire controls the heater utilizes Category IV, AL29-4C corrosion resistant, sealed vent pipe. Factory supplied vent kits are required for some venting configurations - see below.
Modulating (M9) models require Category IV vent material in any venting configuration. On/Off (F9) models require Category IV vent materials when exhausting through a sidewall. Consult I&O manual for exact specifications. *Requires factory supplied vent kits
Exhaust Vent Reducer
Available for installation with Category IV vent systems, the Vent Reducer kits allow the vent diameter of eachPower-Fin model to be reduced by as much as 45%. The vent reducer is made from AL29-4C corrosion resistant material. Because the reduction in vent size creates a “positive” pressure, all reduced vent systems are classified as Category IV systems requiring corrosion resistant, sealed vent pipe.

Designed for Reliability
Lochinvar pioneered gasketless heat exchanger technology in 1989 with the Mini-Fin Boiler. Now we're bringing the same advantages to our vertical chassis Power-Fin - giving you a one piece header design with no gaskets or o-rings to crack and leak. This gasketless design provides enhanced reliability, improved durability and optimizes performance. We're so confident in its performance, we back it up with a 5 year limited warranty against failure and a lifetime warranty against thermal shock.
The interior and exterior of all heat exchangers is
coated with a porcelain glass lining to prevent
external corrosion and provide
clean and clear potable water.
Copper-finned tubes are extruded from a thick copper tube, creating a heating transfer ratio 9 times greater than
regular copper tube - allowing
maximum heat transfer.
Gasketless Heat Exchanger
To ensure fail-safe operation, every major function of the Power-Fin is automatically controlled and checked by a digital control panel with advanced diagnostic features. The large display is easy to read and makes set up's a snap. The digital display, accurate to +/- 1°F, indicates temperature while the LED indicators prove operation and status. This monitoring system not only warns against failures, it can actually help to pinpoint the source of any problems, leading to faster solutions. In addition, all of the components are field replaceable, so down time is reduced.

Time Tested Performance wit
ASME Copper-Finned Tube Heat Exchanger
Gasketless design by the company who pioneered the gasketless heat exchanger. ASME construction built to 160 psi working pressure. Finned copper tubes transfer heat nine times faster than regular copper.
Combustion Air Filter
Creating cleaner combustion the standard size filter is easily replaced by removing from back of the unit.
Service Friendly Design
Power-Fin is designed for easy service and maintenance.
Slide Out Control Panel
For easy and convenient access to controls.
Firing Control System
On/Off (F9) firing is provided as standard equipment. Modulating (M9) with 4:1 turndown is available as an option.
Hot Surface Ignition
Eliminates the need for a standing pilot. Utilizes the latest and most reliable technology in ignition and flame rectification.
Fan Assembly
The Combustion Air Fan draws a precise ratio of gas and air into the combustion chamber based on heat load and
injects the mixture into
a 360° ceramic
burner, which contributes to
the overall quiet operation
of the appliance.
Field Electrical Connections
All models require (2) two 120V, 15 Amp single phase connections for heater and pump operation. Single 30 Amp service may be used.
360° Ceramic Burner
At the center of the combustion chamber is the highly flexible and efficient Power-Fin ceramic burner. The new ceramic burner allows for perfectly even gas and air distribution which results in a NOx Rating of less than 30 ppm - far exceeding the most stringent air quality standards. What's more - the Power-Fin burner is perfect in installations with low supply gas pressure, operating without hesitation as low as four inches of water column.

Ultimate Flexibility
Lochinvar's unique "engineered systems" approach to water heating provides the flexibility to match the heating unit (or units) with the exact size and capacity storage tank that is needed for any given application.
For example: Use a low output Power-Fin with a large tank for short term, high draw situations, or team a
high-output water heater with a small tank for applications where the demand is almost constant. Whatever the need, Lochinvar has a Lock-Temp tank to match it-from our 119 gallon vertical to the 2500 gallon horizontal model.
Each package system can be custom-configured to the exact specifications and available space of each job. These Power-Fin package systems are pre-engineered, pre-piped, pre-tested and shipped pre-assembled on "I-Beam" skids ready for installation.
