Lochinvar FTXL Fire Tube Boiler features the next generation of Lochinar’s all-in-one SMART SYSTEM operating control with a re-designed multi-color LCD interface. SMART SYSTEM provides outstanding functionality and can be integrated directly into a Building Automation System via ModBus and other communications protocols. And now, the CON-X-US mobile communication platform allows SMART System to go where no other fire tube boiler has gone before.

Lochinvar Smart System: Con-X-US

Lochinvar’s Smart System Con-X-US provides the ability to monitor and manage multiple FTXL boiler plants without ever stepping into the mechanical room. CON-X-US will send alerts via text or e-mail notifying of changes in system status, and anytime from anywhere, a user can check system status and re-program any boiler function. Once downloaded, the free CON-X-US mobile application allows for remote access to all Lochinar Smart System functions using any Internet-capable device.

The New 98% Standard of Fire Boiler Technology

Lochinvar redefined the fire tube boiler category with its KNIGHT™ Wall-Mount and CREST™ lines. For residential and light commercial applications, the Lochinvar FTXL adds models from 399,000 to 850,000 Btu/hr, and takes Lochinvar’s fire tube technology to the next level. This Lochinvar boiler offers best-in-class AHRI Thermal Efficiency and footprints, plus remote connectivity that puts the Lochinvar SMART SYSTEM control at your fingertips, anywhere!

How 98% Translates into Lochinvar FTXL Savings

Even when compared to other condensing boilers, the FTXL fire tube combustion system will increase boiler efficiency and produce significant fuel cost savings. Here are three comparisons, based on a building load of approximately 19,000 therms/year, at a cost of $1.09 per therm of natural gas.

Fuel savings is based on a heating load of 19,000 therms per year being supplied by an 82% efficient boiler at the DOE National average for natural gas of $1.09

Lochinvar FTXL Fire Tube Boiler Features

Reduce Installation Cost with Variable Flow Technology

The Lochinvar FTXL can operate over a wide range of flow rates* with very low-pressure drop. This permits installation of a “full flow” (variable primary) system eliminating the time and materials cost of primary/secondary piping and pumps needed to maintain flow in a water tube boiler. Variable flow also makes the Lochinvar fire tube boiler more flexible at handling frequent fluctuations in the system flow rate.

Smooth-Running, Modulating Fire Tube Combustion System

The Lochinvar FTXL fire tube boilers have a top-mounted, micrometal fiber burner, with a blower/gas valve assembly that drives heat energy downward, through stainless steel fire tubes, with exhaust venting through the bottom of the unit. With up to 10:1  modulation turndown, the burner automatically changes its firing rate as building heat loads vary. An FTX500 fires at its maximum 500,000 Btu/hr rate when the heat load is highest, then gradually “turns down” to as low as 10% (50,000 Btu/hr) as load decreases. A modulating system runs smoothly and efficiently, without frequent on/off cycling.

Fire Tube Technology: Minimum Supply Pressure, Installer-Friendly

The Lochinvar FTXL operates with supply gas pressure as low as 4 inches water column. Negative Regulation draws gas into a pre-mix fire tube combustion system, instead of relying on utility pressure through the gas valve. The result is a steady operation in low gas pressure system or when peak demand occurs on gas supply. Automatic fan speed control fine-tunes the correct fuel/air ratio entering the burner, providing superior combustion throughout the entire operating range.

The Smallest Footprint, A High-Efficiency Boiler That’s Easy to Install & Service

The Lochinvar FTXL fire tube boiler can be installed with zero clearance on the left and right, and the boiler’s installed footprint is just 6.2 sq. ft.

All water, gas, and vent connections are in the back of the unit. A hinged top opens for easy access to components and the front panel is easily removed using no tools.

Lochinvar FTXL’s Flexible Venting Options

Lochinvar’s fire tube boiler offers 6 venting options, and permits direct-vent air intake and exhaust runs up to 100 equivalent feet, using PVC, CPVC, polypropylene, or stainless steel pipe. Plus multiple units can be common-vented to reduce time and materials costs.

Fire Tube Technology: Wireless Outdoor Sensor

Easy to install, greatly reduces time and materials costs for running sensor wire from standard outdoor temperature sensor to boiler control. Approximate range 2,000 feet line-of-sight.

Loch-N-Link Easy USB Flash Programming

Use a USB drive to name, store and easily manage multiple existing proven parameter sets. Quickly upload them via the front panel port into the FTXL boiler, reducing installation and programming time by up to 30 minutes per boiler.
