How to Vent everything low profile - Page 2

my norcold runs on 12v/110 too but also runs on propane, is it necessary to vent the fridge if running in propane mode? I don't guess I really understand how propane works on a fridge. That's my problem.

Yes, propane mode is an open flame that heats a coil which removes heat from the fridge through expansion of freon (or R34).

But for purposes of venting, it's like a stove, heater, or anything else that produces CO and can threfor kill you if not vented properly- in addition you should have a propane detector and a CO sensor installed.

Thanks Jage on the tip on the CO censor I figured as much and had planned on the install of it. I will try to keep the fridge setup for electric only and will use the propane for dire straight situations to keep food from spoiling if for some reason the batteries are only strong enough to light the pilot light and run a small fan for venting

I'm not 100% sure but I think there is a hazard of driving while on propane mode as well.

I heard of a rig catching fire when the propane pilot ignited gas fumes at a fuel pump. Not sure if true but it makes sense. Also, when driving, CO could be prevented from venting by airflow.

On the other question, I would think a vent out the bottom behind the fridge or near the rear basement would be the way to go. That's what I have been thinking of if I get a portable room AC.

I thought that as well, but my dad drives with his slide in fridge on propane, and when I asked people told me it was typical. They probably said it was safe, but I chose not to hear it...

Here is a quote from the Norcold N300 owner's manual (propane frig)

"Operation During Travel
While the refirgerator should be level when the vehicle is stopped, performance during travel is not usually affected"

This is the only thing I could find in the manual about operation during travel.

Theoretically it's not a problem because if the flame blows out, the safety circuit will shut off the gas.

I do think it's a good idea to shut off the frig when fueling with gasoline, since it has an open flame.

But RVIA standards require that the frig be located at least 36" away from the gasoline filler for that very reason.

I don't think its a problem with a flame out but in an accident a open propane valve might be an issue. Propane is heavier than air and will pool.

This is true. That's why I wish people started making retrofit hydrogen valves and burners for existing appliances. Hydrogen exits the atmosphere at 45 miles per hour and if ignited burns instantly. You can burn it in an inclosed area very safely without using up oxygen and its only waste after burning is water. With all the HHO fuel cells being made (check Youtube) it would be nice to have your own hydrogen generator on board. You would never have to have a propane tank ever again and you would have on demand fuel production. Would be great for boondockers.
