I got the fairly heavy and awkward tank up the ladder and through the shrink wrap door alone by wrapping it in an old heavy blanket and skidding it over the rail onto the cabin top. A few manic hours later and it was all piped up and ready to bolt on the stove and make up the fuel, water, and flue connections.



Please excuse the poor quality cell phone pics. I forgot my camera today.



The color is a great match for the boat and the large, light colored area brightens up a mostly wood interior. It will be less of a big blank area when the stove and stainless flue pipe are in front of it.

Even with the lousy quality on the photos, they still show the quality of the install you're doing Roger. :D

That's an awful lot of copper to keep polished. lol ;)

Fortunately, it will mostly be hidden. Good thing too, and maybe good for the low res photos also, because my soldering was atrocious. When I'm cramped over trying to sweat in awkward spots like this and realize that a leak will require tearing almost the whole thing out and starting over, I get paranoid and put way too much on with resultant runs and drips down the pipes.

There will be an anodized aluminum grill on the other side of the hole that should mostly hide the mess from contemplation by users of the head.

Wiping the joint with a rag as it cools can make a ragged joint look pretty good.

I'm a bit surprised you went with copper pipe for the fuel lines, as copper pipe can work harden and that would be a big problem if it cracks as a result. IIRC, that's why ABYC doesn't allow propane lines to be copper. Is copper allowed for fuel lines?

Those are water lines. I would have gone with something else except that the pipes are right behind the aluminum plate the heater is mounted on and I don't know how hot it will get and was afraid plastic might become brittle even if it didn't melt. Not all of the lines will be full of water. The Shed 80 PVC connectors to isolate the copper from the aluminum are over to one side. There is also a magnesium anode designed for aluminum RV hot water tanks.

I'm not using any copper lines in the engine fuel system. I am using copper flare for the heater because that's what Dickenson recommends and is what is used in the internals of the heater itself. I'm sure the heater is a lot less fussy about what copper might do to the fuel than an engine is. The lines to the heater will always be shut off when the heater isn't running.

For copper to work harden it must move, if it is fastened to the bulkheads at frequent intervals there won't be any vibration and therefore no work hardening. We used copper hydraulic lines in aircraft until they changed over to aluminum. part of the periodic maintanance was to remove the lines and anneal them.

Ahh... thanks for clarifying that for me. :D

It's coming! Finish the flue and connect the two electrical wires and I'll be ready to fire it up. Oh right, I'd better take the shrink wrap off the boat first.

Dang, I can almost feel the warmth of the cabin ........ Even without heat on it makes it look cozy !

As fine a looking job as I have seen on a boat.

All done except for testing and making a grill to cover the heating vent into the head.

That certainly is neat and tidy and as shipshape as could be asked for. Very well and nicely done.

The last little bit. It's officially DONE except for the testing which will have to await the shrink wrap removal late April after I return from a trip.
