Do you consider a commercial generator exhaust system a mechanical system as covered by the IMC?
Do you consider a commercial generator exhaust system a mechanical system as covered by the IMC?
Why the question
I don't see where the IMC covers a generator outside of a building.Would you regulate the exhaust if the genny was outside?
IFGC?? IFC
So how far is the end of the exhaust pipe to complainer and property line??
Does it go straight out or out and turn up?
It only runs once a month and has been there for years.
It doesn't fit the code definition for exhaust system because its not exhausting air, its actually exhausting products of combustion. That makes it a vent system, not an exhaust system same as a power vented furnace or boiler. Termination locations would be covered in Chapter 8 of the IMC if its a gasoline or fuel oil generator or in Chapter 5 of the IFGC if it is propane or natural gas, but basically the same for either one. Manufacturer's installation instructions must also be followed.
Generators are regulated by the IMC/IFGC because they are listed under Specific appliances as mtlogcabin said. The IFGC version of that section is 615 and is basically the same as IMC 915. Whether it sits inside or outside doesn't matter, or air conditioners and rooftop HVAC units wouldn't be covered by code either based on that logic.
I think according to the prescribed codes, you can consider it as a mechanical system. But Single or combined mechanical exhaust systems for environmental air shall be independent of all other exhaust systems. I don't know if i have answered your question. But thought of sharing what i think i knew. Pardon me if it's a huge blunderDo you consider a commercial generator exhaust system a mechanical system as covered by the IMC?
