Gas plumbing line location options

I would like to get people's thoughts on running our gas line through the boat.
Option one is overhead concealed above the headliner.
Option two is part run above headliner then drop down and run along the side of the hull in behind furniture etc.
Does it matter?

Cheers

Re: Gas plumbing line location options

I've not seen one run overhead before... Not sure the reason why not... I would be concerned about heat and line deterioration if you planned on the tropics BUT... Propane equipment like forklifts and such have some pretty warm spaces where these lines run...

Re: Gas plumbing line location options

Which ever is easiest and most straight forward.

I recently re plumbed an elderly Grand Banks. The gas line ran from the locker on the flybridge, along the deckhead,above the headliner, before dropping down to the cooker.

Neat and unobtrusive.

I wouldn't use rubber hose myself, some of it you may not be able to avoid, but I wouldn't run the whole thing in rubber as it deteriorates faster than say copper

Re: Gas plumbing line location options

I'm nearing my final decision on type of line at the moment. But ill leave that for another discussion or else this thread will drift so bad it will become how to install and what to use instead of the pros and cons of which route to take.

Above headliner or along hull are probably equal in work for me. So ease if install will not really be a factor.

At first I thought if its up high and there somehow became a leak in the line itself it would likely be easier to smell as it dropped. But then I thought it may also be able to find the right ratio to explode easier too.

Of corse the whole system will be done as safe as possible again I will try and refrain from detail on this part.

Above headliner will be harder to access once put back together (headliner is out at the moment)
But possibly a bit more protected then again harder to inspect......

Re: Gas plumbing line location options

Thanks Gord,
Yup I've read that before and just had another read.
I've read everything I could on the subject that I can find and so far there is not a recommendation I could find to suggest to keep the run higher or lower if possible.
Guess it does not matter as long as the other protocols are followed and the install is safe.

Re: Gas plumbing line location options

Running it high might avoid any pests such as mice or maybe a rat chewing on the hose. Just a thought.

Re: Gas plumbing line location options

If your head liner is out, you might consider running it overhead in a channel that gets covered by a separate (removable) trim piece so that you can inspect it whenever you please. Many commercial buildings are done that way for plumbing and electrical, and it makes it much easier for inspection and repair. If done right, it can look very proper. Good Luck. _____Grant.
