I've been scouring the internet trying to find the manual for an Arrow Model I20 wood stove insert. The chimney guys are coming tomorrow and I've got nothing! I seem to know everything about the company, including that they were bought by Heatilator. But despite the dozens of manuals the Heatilator website has, there is nothing for Arrow. I reached out the Australian company that now seems to manufacture Arrow, but nothing. The date on my insert is 1992, which is right at the legal cut off here in Oregon, and I'd like to be able to keep it, but I need the manual! Any help would be greatly appreciated.
