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. 

Easy Access to 

Internal Components

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.
