you see, the code IS up for interpretation because what he suggested could be interpreted as violating the code by some people. Is statement is in direct contrast to other sections in the code. Refer to the secition, directly out of the Residental Code, you can not directly exhaust into the attic with anything except a whole-house ventilation-type fan, if it was being used for ventilation of the garage, than it is not being used for the whole house, unless you did one of the stupid options I listed. Not only that, but the code also prohibits using air from the garage as return air, there is a reason for that, so why push it back into your house through the attic? Makes a lot of sense to a complete fucking dolt like yourself I guess.
Regardless of the code issues, that 7 hears of brazing copper pipes and charging HVAC systems didn't give you any knowledge of why installing that fan is a horrible idea, which I explained twice, yet you didn't get it. Yeah, you win on the code issue, congratulations, you happen to interpret the residential code the same as some other people, but you are 100% off base on that being a good idea.
Stick to toating around guns in the desert, installing residential HVAC units and misspelling quite several fucking times, because that is all you are qualified to do, quit giving shitty adivce on things you know nothing about. You have no idea what effects installing a high powered fan basically inside the house would do because if you did, you would realize what a moron you are.
