Stovetop Burner Question


Adventure Location: Rockport, Texas

The labels that say to not use the stove top burners for comfort heating have always amused the OFM. The OFM needs an explanation. Why is comfort heating with a certain size flame on a certain burner going to kill him but if he puts a pot of beans to cooking on the same size flame on the same burner for the same amount of time it is ok. Do the beans or other food absorb something to make the air safe? Is the food then unsafe? What happened to the bad stuff that was going to kill him? Hmmm interesting! Those are some really smart burners to be able to tell if cooking is going on instead of comfort heating.

Morning arrived with chores to do. An important chore is to uncover the duct vents in the floor of the Castle. For several years now the OFM has used “throw rugs” from Wal-Mart for keeping his bare feet from feeling the cold floor vinyl. While the furnace is not being used, the floor vents are covered and that keeps junk like small rocks and debris from falling into the duct work. But with the furnace coming out of retirement the ducts need to be free and clear of any obstructions. The major chore today was to get the ducts uncovered.

Here is the rug covering the duct in the bathroom.



The soft rubber backed rugs stay in place pretty well. They would likely get very soft with the furnace trying to send hot air out the duct. Melted rubber is not a wonderful fragrance for living quarters. The solution chosen was to cut openings in the rugs to let the hot air pass the rug. This was actually done in the past in the first Arctic Fox trailer the Teams had up in Washington State. It works very well we found out.

Crawling around on hands and knees is the only way the OFM could get down to mark the vent. He feels around the raised vent cover that is under the rug.  Then moves out a nice amount and marks the cutting line with a marking pen. That is the easy part.

The rug was lifted clear of the floor and the cutting began. On this first one, a pair of cheap scissors was used.  It was hard work. These rugs are tough. 

For the next three holes we found that a sharp utility knife worked much better and gave a much better cut line on the rug. The rug was given a trial fit and nay corrections were done at this time.

Then the edges of the rug cuts were sealed with a flame from this igniter.  Slowly moving the flame along the edge of the cut line melted the fibers to the base mat.  Now the rug will not be unraveling. It is possible to hold too long in one spot and set the rug on fire. However it puts out with a nice blow of your breath. DO NOT PRESS ON THE HOT PLASTIC TO PUT THE FIRE OUT. YOU WILL GLUE YOUR FINGERS TO THE RUG WITH VERY HOT PLASTIC. No the OFM did not do that (this time).

After all this work the furnace is now ready for the repair man on Friday. But it was not to be. After some fishing at the waterfront, the Fishing Team returned the OFM to the Castle for some rest. He got to thinking that the furnace should be tried so that he could tell the repairman exactly what is happening when the furnace is starting. Good idea was the Teams consensus.

The thermostat was set to heat and the setting was raised to 85 to force the furnace to cycle and give us its clues.  WRONG AGAIN AS USUAL. The furnace fired up like it is supposed to fire up. Everything went exactly perfect.  What is going on???  To cut to the chase, we waited a half hour and tried again. Same result, perfection. Another hour wait, same result. So the appointment for Friday was cancelled. It is hard to get a repair on an item that is not broken. It must be leprechauns hiding in the furnace. Anyway now as soon as the mail from the Escapees mail service arrives the Teams can be rolling.

Having a working furnace certainly gives the Teams a lot more choices in where we go for trying to have tooooo much fun. TheOFM.

  1. It might be hard to repair a non-broke appliance, but it wouldn't have been hard to charge a service call for it. Glad you caught it.

    1. I wish it had been some bit of brilliance on my part instead of plain dumb luck. But I will happily take it either way.

  2. I don't know why I didn't think to cover the vents in my house this past summer. Good idea about the small rugs. Your header photo is beautiful, by the way.

  3. When cooking, the stove burner is on for a limited time. When used for heat, it may be on all night or for an extended time.

    I like your cut out rugs. When the registers are not being used, you can replace the piece that was cut out.

    1. Thank you DD for mentioning that burners might be used for different time frames but my question still remains unanswered. When I cook some of my concoctions, the burner has remained on for over six hours under the pot while it simmers. How is that different than the same flame and time without a pot?

  4. I enjoy your blog, Barney. Had a laugh about the fact that you didn't burn your fingers THIS TIME. We live in a trailer for 3 months of the year, so we are familiar with lots of your post material. I googled "danger of using propane stove for heat". All I found out was that the stove puts out fumes, and that moisture coming in contact with the fumes is dangerous. I think DD is right, though. I think it's the time frame that makes the difference. When we've used the furnace to heat our 30' Class C, the propane level went down fairly fast. That's what I'm wondering about in your case. RV Sue seems to handle it very well, though. Living in the trailer, we have an option to use electricity (that's included in our site charge), so we skimp on the propane, which we have to furnish. Use electric heaters, blankets, and toaster ovens. We have rugs over the vents. You are right---that keeps them clean, and keeps the warm air in.

    I will be following your blog to find out where you're going. Suppose you're going west where the nights are cold, but the days are warm? Take care.

    1. Perhaps an actual event that repeats in my use will make it more clear about the question. When cooking certain concoctions, I simmer the "stew" for six hours on the stove. When I use the stove for comfort heating, the burner is set at the same flame but for only two hours before I go to bed. Six hours cooking is ok supposedly but the two hours of comfort heating is not. That is weird to me.
      Proper propane combustion yields water and CO2.
      West is correct. Probably over to the Rio Grande River.

  5. I often wondered about the stove thing myself. I'm thinking they must mean do not sleep with it on. I would never go to sleep and leave my stove lit. Not even in my house. But I have read that you shouldn't do it in your home either.
    Just my thought.

    1. Jo, I agree with you. I never want an ignition source like a catalytic heater or any flame heater running while I sleep.

  6. I really think it's lawyer-ese for; we(the manufacturer) don't want to be held liable for you burning the place down(unattended open flame...Supposedly you are hovering over the stove while you are cooking.) OR asphyxiating yourself with CO while sleeping. I don't see a logical reason for the warning except for product liability and some folks have no common sense.

    1. Judy, I feel that you have nailed the real reason for the not logical statement.

  8. Barney,
    At the beginning of every winter you hear stories of some poor family burning down their home while using the gas range for heat. I don't know how this happens but I think that's why the warning.
    About your furnace, I've had two occasions when mine didn't work temporally. The first time I was low on propane. Not out, just low. The second time I was pulling through a heave rain storm and the 18 wheelers were blowing water into the furnace vent. After a day of dry weather it worked fine.

    1. GB, Thank you for the info on your furnace. I was very surprised when mine fired up.
