Need to vent? We'll be here.
Not only are all KN Series built for the long haul, all are designed to be compatible with numerous venting configurations which comes in handy when challenges arise in real-world design and boiler installation scenarios.
With the option to be vented as Category II or IV, KN Series boilers also allow for combustion air to be piped directly from a fresh air intake through a sidewall or a roof. Utilizing mechanical room air for combustion is another commonly used venting option.
