direct vent exhuast

IMHO,

The 10'ft. "rule" applies only to an exhauster or mechanical exhausting systems and its intent was not to include a direct-vent condensing boiler. I believe the term "exhaust" when referring to a mod-con boilers can be misleading to some code officials. If you follow the manufacturer's installation instructions to the letter and refer the official to IFGC Appendix C and section 304.1 you should not have a problem. Depending on what the official cited (did he leave a sticker and if so what did it reference) he "may" have been referring to IMC 401.5 which in this instance should not be applied. Also see IMC 804.1 which specifically states to be in accordance with the manufacturer's instructions.

Good Luck!

    Sounds like...

    The AHJ is enforcing the NFPA standards...

    You are in compliance with the manufactures

    installation instructions. I guess all you can do is plead mercy and ask for common sense understanding and show him that you are in compliance with the manufacturers requirements.

    Most reasonable inspectors are looking to limit their jurisdiction's liability. What liability will you have from a vent termination 22' above grade?

    Worth a try...

    NFPA in section 12.9.1 you have to be at least 3 feet above any forced air inlet within 10 feet. There is no rule for being 10 feet from a property line. We have been looking at the 10 foot rule due to icing on opposite buildings. If there is a rule, it is a local bylaw and not in the gas code.
