Church mechanical room in NC
I have a mechanical room in a church fellowship hall accessable only from the exterior of the building. All walls are constructed from 8"CMU. The mechanical room contains an oil fired furnace and water heater. They wish to install an interior door to the mechanical room to access some storage space and install a mop sink. Does code require the interior door to be steel? If so, what fire rating should it carry? I think the door should have a threshold and weatherstripping to seal out noise, possible odor and noise.
Also what, if any, are the fresh air requirements for furnaces?
