propane appliance hose

[mmg440]

Well, I had my furnace go out last week. It a Nordyne unit and I had two problems the fist and main problem was the surface igniter failed the second was the induction motor sometimes is failing to start. I got the unit fired up manually because by the time I woke up I found the house at 48 F. Not yet frozen but it was about 2 below outside so it wouldn't of taken much longer to freeze pipes. So looking for a local suppliers the next day we found a Robertshaw same length and adaptable at a local Granger. It the mean time I had brought on of the small propane heater in that I use for small jobs in the garage. I pulled the induction motor of the furnace and was able to lube the bushings with penetrate and it now turn much smother. I should get buy for a bit with that. That night I got the furnace up and running. I had left my space heater inside and would of brought it back out this weekend. I cam home Thursday after work to find the propane hose to the heater had blown the fitting to the tank out. I get a sick feeling and I had also left the tank on! I really had a hard time believing my stupidly. The near disaster that I almost caused. The tank has some sort of safety valve that shut the flow off other wise there would of been 15 pounds of propane in my hose all at once, and with the new surface igniter installed it would of been sure to have a good source for ignition. I know these type of propane appliance hoses are not meant to be used indoors. but I never expected it to fail this way.

Wow...........All i gotta say is glad you're alive. Glad your house is in one piece.

Yea, I am glad too. I am glad to just have a wake up call like this then a unforgettable learning experience.

Very dangerous set up you have there.There should be a regulator attached directly to to tank before it goes to the hose. Wouldn't hurt to have an anti flash back valve either, especially if you are using this indoors.

The regulator is in the heater. It is a 20lb to a 1lb cyl type hose. I usually only use it outside or in the garage. I brought it in for a little heat while working on the furnace. They are sold as a complete unit and was not home made or anything. When I ordered it I expected a hose as in this link.

But the suppler I ordered threw sent the one with the plastic coupler. Same as we see on the grills BEFORE the regulator. I do not see that much difference the pressure before a regulator on a grill and in this use is the same and believe there was probably a flaw in the part to start with more so then the set up. Altho I will be much more hesitant to bring the large tank inside to hook up again. The heater is a Mr heater "Portable Buddy" and is rated to be safe indoors with the single use 1 lb cyl. They do state NOT to use the 20lb with a hose indoors..(with tilt, shock, low air, pilot - safety ). I just figured in case of leaks. I did not expect the hose to break and I just plain forgot to shut the tank off or get it out of the house when I was done! (my very bad)

So the manufacture did indeed ship the new replacement hose on Monday as they said they would. I received it today. I carefully inspected the fitting and see no cracks or anything out of the box. They were fine with just emailed pictures of the defective one. I would of thought they would sent a pickup for the old one to examine what went wrong. Well to say the least I will not be leaving the tank on unattended anymore!

Looks like at one time or another the black plastic nut was either overtightened or the hose got pulled sideways and overstressed the plastic.
That connection is designed to be hand tightened only, if it takes a pliers to get it off you had it too tight.

And no, I'm not real thrilled with the new connectors either, just another fine example of how we continually have to dumb stuff down to contend with those who refuse to learn the basics.

I have had this hose for just over a month. I bought it after getting the heater I got for Christmas. It only has been hand tightened. Alto with no O ring just the brass taper I might of gave it a solid twist "by hand" and that could of been damaging. I would of thought I would here it crack or feel it brake. I would of not needed any tools to remove it. The hose has not been tugged on. To me the plastic fractured almost like a chemical type attack on it... Alot like break-clean does to some plastics. I am going to be aware of this on this one and keep a eye on it condition. I would of been much happier with a metal connector but the new one is of course still plastic and of course is "made in CHINA"
