We had one on our E38 when we bought it. We tried it a few times and it is not very effective in the 38. It needs frequent tending due to the small fuel box. Ultimately we didn't trust the chimney/flue system to keep CO out of the cabin and at the time we didn't have a CO detector. Ours was located in the salon on the right side bulkhead to the v-berth, too.
It was a Cole Stove, by Ratelco. I have the instructions , 7 pages, that I can scan for you.
