Co ppm limit for combustion tes

What is the max co ppm limit up the flue and we're is it documented. I always go for 0 to 150 ppm in both residential and commercial but looking for a documented code limit.

    400 ppm as per the EPA, but I wouldn't want to go that high. There's also ambient maximum levels/hours exposure. You'll have to google it, but it is on their site.

    You can choose to do what you want, but you cannot choose the consequences.

    The ANSI Standard is 400 PPM allowable in a flue sample. We however strive to get 100 PPM or less. A lot of new Mod/Cons give a number they want for their equipment. Contact me at [email protected] and I will share some information with you.
