Hi Alistair. Galaxy Quest? Ha! :) Not that you were saying this, but yah, I might have caulked needlessly on the flue fittings. But they're sealed and any excess would have gotten pushed out of the way. (but not in way of exhaust & intake openings I think) Re flue assembly. I aligned manifold to the body. pic: http://tinyurl.com/2g537pw Gasket held up, holes lined up almost exactly. SS plate behind flue cover installed with straight edges on horizontal, hole over exhaust. The only *possibly* error; the aluminum piece. But I compared the exhaust print and print of manifold, via gasket, on 2 sets of flue assembly parts. Offset "O" on AL piece over exhaust outlet as per this pic: http://tinyurl.com/34rcuex Is that correct? Never give up yes. But... the thermocouple in combustion box may be worn too short. I saw a similar or same part on GW for ~ $70. At least double that of other thermocouples I've seen. And, if interior vent fan added, that = 4 fans for the Dometic. In hot weather, during daytime, this might mean a constant 1 Amp draw. IIRC, a DC fridge draws ~ 2.5 - 3 Amps. But not all the time. And.... it actually keeps things cool even in really hot weather. Then again, parts for a DC fridge could be pricey. I love the idea of a fridge that can be off grid. One that doesn't cost a bunch of money. But if I'm going to be adding fans to keep the Dometic *possibly* working in uber hot weather, then I might as well draw down my battery with an actual fridge. I do understand though that it's a big outlay of cash for a DC fridge. Harumph. ;) Neil.
