Search for regulatory documents for bakery ventilation

Good afternoon, Veronica. I advise you to work out “SNIP 41-01-2003”, especially section 10, concerning emissions of contaminated substances. I won’t rewrite the points - I attached a screenshot. In addition to the dimensions, which regulates the location of the pipe relative to the elements of the building, there is an interesting point 10.1 that requires preliminary cleaning of emissions. You don’t need cleaning, but there are cleaning devices that remove the problem of a high ventilation pipe.

In addition, there is a question on the site’s forum: “How to arrange ventilation in a mini-bakery?"- I recommend reading the answers.
