I had one when I installed the furnace in my garage. What a pain in the rear, but I was worried about what Kaisen stated above. With Denver it was $45 for what I was doing, which was a furnace, ventilation and new gas line.

The first inspection, the gas line and furnace electric passed, but not the vent. My garage furnace has a forced exhaust and the inspector told me he had to see the owners manual to certify the vent setup. I didn't have a manual since I purchased a used furnace.

I purchased the manual from the company and called the inspector out again. He couldn't understand the manual and would not certify it. Finally his supervisor came out a week later and took about five mins and signed off on it.

So I guess any advice I would have is have the documentation in hand and ready. Oh and my installer was also very helpful in advising me on dealing with the permit man, it was Braconier Plumbing here in Denver.
