Hi Roger. This is a stock Coleman Peak 1 Model 5452-700, remote propane tank stove. Won on Ebay, but didn't include a manual or the tank stand. I could not find any info on the net either except for this: http://www.coleman.com/coleman/parts/product_category2.asp?category_id=210
I also won on Ebay a week before a Coleman Mountaineer Series Model 3025-701 stove (right)...dare say almost identical twins.
The manual on this one is dated Nov 1997.
The valve on the LPG bottle is the "regulator knob"...OFF and ON has 7 position clicks for what I quess is fuel volumn flow control.
The valve on the stove is the "burner valve"...will not turn off the stove but will adjust the flame in any of the 7 position clicks. Rotates 180 degrees. Connects to a regular 16.4oz propane tank or, with the right hose, to a bulk refillable propane cylinder.
The outer ring is the windscreen with the attached 5 fins acting as, I guess, wind deflectors. The jets are around a disk-like device at the bottom of the shallow bowl.
The built-in windscreen does a great job of blocking wind...these are the only stoves that I've gotten 1L water to a roiling boil at 12-15mph winds without any sort of wind
Roger, need anymore info, just ask and I'll answer best I can. BTW, I enjoy reading your posts and articles...most informative. Thanks
