We have a 1968 Kit Companion 17 footer. It has a Hydro Flame propane furnace that was working great, until the flow control handle fell off (somehow managed to unscrew itself over time). The furnace looks identical the photo's here (so likely an ARS-10L as well.)
But of course, I had to remove the flow control assembly so could screw the handle back on, but that resulted in several springs and pieces coming apart when I pulled out the flow control assembly.
Try as I might, I can't seem to find the correct positioning of the springs and a small plate that fits with the springs.
I realize its a long shot, but does anyone have a photo or assembly diagram of how to put the flow control back together?
