How far can you extend the intake & exhaust for an IBC combo boiler

Options
The inspector said these lines are too close to the ground and should be higher. The location is bad under a window anyway and also in a walkway. I can relocate it pretty easily to the other side of the house and raise them but my question is how far can the lines be extended from the boiler. The boiler is an IBC

    I can see why the inspector objected...

    The distances will be in the installation manual.

    Call the installing contractor and make them run them according to the manual!

    all mod cons are different. You have to follow the boiler mfg. instructions

    I know the rules in New Jersey say that the contractor can not receive payment in full until the work passes inspection. But who follows the rules in NJ. I hope you didn't pay in full yet.

    After you make that expensive repair and you still have the same problem, What will you check next?

    For 2” vent, most IBC only allow 35 feet, and an elbow is a 5-8 feet equivalent. you can find the brochure for each model at IBC.com.
    Is the objection because of distance from floor or because it is in high traffic area? Unless there is a more stringent local code, standard US is 12” minimum from floor. Be it that you or the contractor does the change, got to make sure inspector is going to approve.

    I see an issue with below the window and snow load. Termination may also be an issue.

    You would have to check your local code and the manual but the min height is usually something like 12" above maximum expected snow height.

    The intake and exhaust also need to be separated by 24". 12" above anticipated snowfall. 12" from a window as a direct vent appliance.

    IBC manual calls for 12” minimum from floor and 12” vertical separation between intake and exhaust if not using a concentric or a low profile termination kit.
    But what your inspector or local code is calling for is what matters.

    If it is on a windward side it could create a mess, especially when the exhaust is wet.

    Sidewall venting is always a compromise in my mind. Exhaust all thru the roof options, pun intended.
