Wow! a seemingly non-boat non-house regulator
in a boat? Is there, somewhere out of the picture, the ABYC standard solenoid cut-off for gas flow so you can isolate the bottle from a switch in the galley
? Having seen one questionable item in the gas system, I would recommend a review: Pressure guage for testing leak-down after the solenoid is shut off, solenoid, regulator
, one hose with no joints reaching the stove, or if multiple uses, all the joints in the gas bottle storage
box that vents off the boat, and hoses in good shape. Hard-wired gas detactor on the cabin sole
by the stove. Whatever the composition of the gas, it's more dense than air, and a failure outside the vented box means a boat full of explosive gas/air mixtures. Inspect that system!
