External Propane Line

We are new owners of a 2016 AI with an external propane line about 3 feet long. We wanted to hook up a Coleman lantern outside so bought a 10 foot line. Propane flows well in the shorter line but not through the ten foot line. Has anyone had success using a propane Coleman lantern off of an extension line? Thanks

Maybe Different pressure requirements???

Do you know what a learning experience is? A learning experience is one of those things that says "You know that thing that you just did? Don't do that."

Sometimes a longer line can cause the excess flow valve to trip....takes 3+ times the gas to fill the 10' line and if the valve is opened too quickly it will cause the EFV to trip. Resets itself in a bit of time.

External Propane Line

I have a 10 ft line on a portable NG heater on my deck. It takes a long time for the gas to reach the burner so I can light it. I recommend you hook up your Coleman lantern with the long hose and leave it sit for at least 30 minutes before trying to light it.

We have a 10' quick-connect extension hose which has an integral on/off valve for our generator. The first time we used it, it took ages to get the gen started (for the propane to fill the line). So we got an extra male and put this in the female end fitting (so as to open up the line to gas flowing), and then opened all the master on/off valves until propane flowed freely out of the end near the genny.

Low pressure propane lines, it turns out, are very low pressure, such that you can put your thumb over the open end, and stop the flow of gas by manual pressure alone (IMO).

When the gas smell was strong, we turned off the valve, removed the extra male fitting, and connected the line to the generator. After priming the carb, it usually starts after 3-4 pulls. And this is true even if we use 2 10' hoses to hide the gen behind the trailer, so it is at the quietest spot in the campsite.

Good luck!


PS -- FYI extension hose with shut-off:

Propane flow rates of lantern

A quick search online shows the Btu/h of a lantern to be about 3500. I have a 12ft. hose on a 15,000 But/h single burner stove with a quick connect that I use to cook outside for various reasons. It takes roughly 10s for me to purge the line and light the burner. The quick connect on the outside supplies propane at a pressure of around 11" wc (less than 0.5 psi), in other words- low pressure. You either need to wait longer to light the lantern or the lantern requires high pressure. Check the pressure requirements for the lantern.
