Chimney Affidavit

drblinkdrblink Member Posts: 4
My plumber needs an affidavit from an engineer stating that my chimney has the capacity to vent 2 boilers and 2 water heaters. All 4 appliances use natural gas. I've been calling various companies looking for someone who can provide this letter but it is proving difficult to find. What kind of engineer would provide this? What companies offer this service in Queens, NY?
