Hey everyone, we are working on an older system that is functional but no one has any documentation for it. Does anyone out there have any documentation for the Thorn Firequest 300, the board is different from the 200. A sticker on the panel indicates that this may be a Grinnell Common Function Board with a model number of 910681. It says to refer to the installation sheet 19700312, so if anyone has any documents related to these components I would be super thankful!
Thanks!
