Easy Access to Internal Components

Easy Handling on the Jobsite

Because of its compact design and stainless steel heat exchanger, KNIGHT XL boilers are remarkably lightweight and easy to handle on the jobsite.

Direct-Venting up to 100 Feet

KNIGHT XL offers tremendous flexibility for placement of units within the building, because it permits direct-vent air intake and exhaust runs up to 100 equivalent feet using either PVC, CPVC or AL29-4C stainless steel vent pipe. Intake and exhaust runs can terminate horizontally through a sidewall or vertically through the roof.

The front and top panels of the KNIGHT XL boiler can be quickly removed without any tools. This provides fast, easy access to internal components and electrical connections during installation and service.
