Re: Shipmate Gimbaled Gas Range
Propane hose comes in standard lenghts. They have a standard 1/2" (if I recall right) NPT fitting on each end that fits the stove and the regulator or solenoid. Use teflon tape. There should be no fittings or joints in the line between the tank and the stove. With your tank in an external locker, you will also need a solenoid valve at the tank that is controled by a switch at the stove, so from the stove, you can cut the gas off at the tank and let the propane left in the line burn out before shutting the burner of oven off. You'll also need a low-pressure (as I recall) regulator. Marine supply places usually carry all the parts you need.
If you have room for a bigger tank, a lot of people use 20-pounders.
