Colman Stove off of House Propane?

[DosMars]

Has anyone rigged up an adaptor to run a Colman stove off of a 20 lb propane bottle?

We have a propane hose by the barn door that originally went to a Suburban furnace. We set up a table right there with our Colman and every now and then I think of how nice it would be to just run a 4-6' hose off of that fitting end and run the stove from the house propane. (see pic. Basically a hose with a fitting that attaches here and has a 1 lb propane fitting on the other end to go into the Colman regulator)

I see a lot of fittings out there but without handling them to make sure everything mates properly I figured I'd see if anyone had already made this work and if you might be able to point me to a part number...?

Mark, that is the supply fitting by the barn door? Threads are in the ID?

Are the threads the same as the end cute one pound propane bottle?

[DosMars]

Yes, that is the supply that goes to my house propane.
The threads are male, I'll get a pic of a 1 lb bottle by the threads for scale but I believe they are larger than the 1 lb bottle?

Buy what looks like it would fit from Amazon ? If it doesn't fit return it - if you're on Prime ?? Let us known what works by posting Amazon thread as part of this post !? Good luck !

A little confused about your 'current' propane supply... Do you have a propane tank which SM installed (to the frame underneath - behind front tire on drivers side)? You would have an access door just behind the drivers door.
If so, Many of those installs already have a high pressure valve available - just before the regulator. You could easily get an extension for that. Otherwise, I suspect the hose you are trying to use (your pic) has a regulator at the other end, and you don't want to run through 2 regulators (propane tank, and stove)..

Yes, house propane is on drivers side mid-van (E350)

Turns out the threading is exactly the same as a 1lb propane bottle. I'm definitely going to have to recalibrate my peepers, I would have sworn those threads were at least 1.5-2x as big as the ones on the bottle!

Looks like I just need an extension to go to the Colman stove. Are you saying there would be a problem going into the Colman regulator?

That hose has been open to the road grime since we bought the van 12 years ago so will probably be replacing it as well to avoid shooting any gunk into the stove.

I'll measure it out in the morning but the 4' hose should do the job. The 6' would give us a little more wiggle room...

Take a look at the Picture on Post #13 on this Thread
https://www.sportsmobileforum.com/fo...r-28700-2.html

I suspect your set-up looks very similar. If so, then the Propane line you want to use already has a regulator near the tank (so if you so if you use an extension hose to your Colman, the Coleman regulator becomes the 'second' regulator).

BUT, if you look at the picture from the attached Thread on Post #13 (and read post #14) you can see where your chassis mount tank may already have a 'high pressure' access - if you get an extension hose to reach that port you'll only be using one regulator (the one on your Coleman stove).

Running through 2 regulators 'is' possible, but the majority that have tried this find the performance of the appliance at the end doesn't perform well (in your case you may get the Coleman to light up, but probably will not have enough line pressure to get as hot as the unit is designed for).

EDIT: Since your addressing the Propane system, might take this into consideration (I copied it from a post which originated a couple years ago):

I didnt know this until I had my tank replaced a couple years ago and the guys at that shop told me - so I asked the people at a Propane Fill station shortly after, and they acknowledged the same:

Recommendations:
All gas hoses and clips should be replaced every two-five years
Gas regulators (Gas cylinder regulators) should be replaced after every five- seven years.

This may be helpful for self diagnosis: (but states 10yrs for the regulator):

Felix, I have not messed around w the Suburban furnaces much. Is the supply to the furnace high pressure or low? I would expect it to be high pressure with a heater mounted regulator managing the pressure.

I am thinking if DosMars removed the furnace then the that supply should be high pressure which the Coleman regulator would then be happy with. The fitting certainly needs some attention!

I believe that RV appliances run off of low pressure. So any line that was attached to the Suburban Furnace would be on the wrong side of the regulator to use a standard Coleman stove.

If you want to run high pressure stoves, etc. you need to have a T before going into the regulator that would feed the Coleman stove.
