KNIGHT Features

10 Models - The Right Choice, for Every Application

Advanced Negative Regulation Technology

KNIGHT safely and reliably operates with supply gas pressure as low as 4 inches water column, because "Neg/Reg" technology automatically adjusts fan speed to ensure the correct volume of fuel and air entering the burner.

Fail-Safe Direct-Spark Ignition

With each call for heat, two electrodes ignite the fuel/gas mixture. A third electrode then senses for flame. If no flame is detected, the system resets and attempts ignition four times. SMART SYSTEM will lock out and display the fault if ignition does not occur after four attempts.

Two-in-One Stainless Steel Heat Exchanger

A primary heat exchanger combined with a secondary heat exchanger capturing flue gas heat allows entering water temperatures as low as 50°F without a low-temperature bypass. The stainless steel, pH-tolerant design features a weld-sealed assembly with no O-rings or gaskets and does not require special glycol. ASME Section IV approved and stamped.

Fully Modulating Burner with 5:1 Turndown

The SMART SYSTEM allows fully modulating combustion with 5:1 turndown. The burner can fire as low as 20% of maximum input, and modulates the firing rate up to 100% as demand increases. The woven stainless steel mesh assembly fires in a 360° pattern along the entire length of the heat exchanger. These together allow KNIGHT's compact size to excel compared to units with larger multiple burners.

Ease of Installation

Direct Venting up to 100 Feet!

KNIGHT offers greater flexibility than other boilers for placement of units within the building, because it permits direct-vent air intake and exhaust runs up to 100 equivalent feet, using 3" PVC or CPVC pipe. Wall-mounted KNIGHT models also permit intake and vent runs up to 40 feet using 2" pipe. Intake and exhaust runs can terminate horizontally through a sidewall or vertically through the roof.
