rrgane / Randall,
As shown in Faster's photo and the one below, I think most installations of heaters are on the main athawartship bulkhead.
Like yours, mine uses a liquid fuel (diesel), and so there is an additional installation issue of where to put the fuel tank. My recommendation would be, at a minimum, to put it on the other side of the bulkhead. Although it seems obvious to locate the fuel tank away from the heater, I know a very experienced sailor who lost his boat filling the fuel tank while the heater was still hot. His tank was in the same compartment, above and to the side of the heater and....you guessed it,... he spilled some fuel. Boat burned to the waterline and sank. That's a round about way to make another point re the installation of the tank -- put it somewhere where it's not too difficult to fill it. (I made the mistake of installing one in a locker. I thought I was being clever getting it out of the way, until I tried to fill the tank.
My heater was installed with copper tubing as a fuel line. It has been pointed out in other threads that copper tube 'work hardens' if it is stressed dynamically, but in the case of this installation the tube is relatively short, and is well secured to the bulkhead every foot or so of its length. You can see from the photo that the fuel line comes through the bulkhead just where it enters the fuel regulator, so it's pretty well protected from heat. I believe Faster has a better set up where the fuel line (seems to be a gas line) is below the heater and shielded by a wood covering.
Per Faster's suggestion -- note the fan above the heater. It works very well in getting the warm around the cabin.
Good luck with the installation.
