I"ve recently insatlled a DS Machine 1500. My brother gave my what appears to be a barometric (or some sort of) damper.
My problems are three fold (1) there are no instructions for the safe operations of the device, (2) although there is no
manual type damper in the device; it seems (as there are holes on either side of the pipe to accomodate the handle) there
should be. Yet everything I've read tells me that a manual damper should be at leate 18" below a barometric damper. And (3)
I can find nothing about the device or the company that made it--It is Heatrite Model R66, manufactured by Heatrite
Regulator Co. Of Phila Pa.
Before I do something stupid, can someone out there educate about this device or should I just junk it?
