I don't recall seeing that code about being 18 inches off a garage floor??? Is it a wood floor??? I have a cement floor so I am guessing not necessary in my case??? Or as many towns do...they institute their own regulations???
Thats a nice Russo....I had one just like that but it would have been too big for my 14 by 22 shop so I got my hands on a smaller Jotul compliments of BigBo!
