Re: Propane system inspection
Here's how I would DIY.
Check the tank locker. It should vent overboard, as propane is heavier than air and will fill the bilge, if it doesn't have a path overboard.
Check the date stamped on the tank. If it's a steel tank, I think it can't be filled after 10 years (your local propane fill station will tell you). Fill the tank or get a new one to fill.
Check the electric solenoid, which should be near the tank. Does it click on and off, when the breaker is activated.
Check all hose connections, by spraying soapy water. Same way you checked for a bicycle tire leak as a kid. Be sure the stove and oven knobs are off, open the tank valve, open the solenoid and spray every connection, from the tank to the stove, to check for bubbles. If you find any, turn the gas off, at the tank, and correct.
Once the above all check out, open up the tank and solenoid and attempt to light the stove. It may take a while, if air needs to be purged out of the lines. I use a BBQ butane lighter, as it's hard to know if the electric spark button on most stoves is working. Ventilate the boat well. Run the gas for a few seconds. If it doesn't light, stop and wait a few more for the gas to ventilate, then repeat. On most propane stoves, you need to turn the knob to a start position, then hold a button or knob down to override the thermocouple safety, to allow the gas to run. This safety will close the burner, when cold, so if the flame goes out, it theoretically keeps the boat from filling with gas. Very theoretical. Keep an eye on all open flames aboard. Once lit, hold this botton or knob for a few more seconds to allow the thermocouple to warm up. Then let go and the burner should stay lit.
Once you have all the burners lit, go over and shut off the solenoid breaker and watch the flame go out to know the solenoid works. Then shut off the burner knobs.
The only thing I suspect a DIY would miss is whether fitting and hoses, etc, were up to proper code.
