We had no major nightmares but the kettle venting was a challenge because nobody at the city understood what it was exactly. So they didn't like what we had installed for the steam vent, but they also couldn't tell us what they wanted. So we ended up having a mechanical engineer redesign it, draw it up, write a letter to the city, and then we tore out the venting and re-installed double wall insulated venting with 2" inches of clearance all the way around. Complete and total overkill, but I can push lava through it now if I want to.
Uh, yep.
