The thing that makes propane safe on a boat, besides a "perfect" installation
, vigilance, and maintenance
of the system, is the fact that after cooking
, you do NOT shut off the burner... you flip off the solenoid switch and wait for the flame to go out. (3 sec) THEN, you turn off the burner's valve, and stove's main valve. This way you know the system is off, and lines purged! It is not safe to keep interior
propane lines pressurized all the time.
Exceptions? A couple... First off, propane refrigeration
like a Dometic, is an option on "level boats" only. They work very poorly on a heel. I have seen one installation
that seemed safe enough...
It was on a catamaran
that was kept anchored out and facing the wind
OUTSIDE, on the back deck
, down in a vented well, was a portable "Dometic" ice chest style propane fridge. The LP tanks
were in a remote
vented location, and had a "T" in the line. This allowed a solenoid actuated shut off, in the hose that went inside the boat to the stove, but the other hose to the LP fridge was always on.
I suppose it could be done on an anchored out house boat as well?
My friends did this for years, and never blew themselves up... but I still feel that leaving the system pressurized is too risky for my blood.
Campers are a totally different animal. The refrigerators are vented directly out the camper's wall, as is the furnace. (This is not just about propane leaks
, but carbon monoxide poisoning as well.) Also... propane goes down. A very small amount of gas would presumably get out through the numerous air leaks
near the floor of the camper. It has no bilge
Hope this helps... Mark
