Replacement Furnace - What Type Fits

[Michelle A]

Hi There,
Has anyone replaced their furnace in a 70's Boler? The counter is rather shallow and my local RV dealer doesn't think I'll be able to find a replacement furnace that will actually fit. I'm sure others have done this... if so, can you please let me know what type of furnace fit best? Pictures would be most helpful!

Thanks!

P.S. Sorry for ALL of the posts about furnaces - I can never seem to find what I'm looking for with the search function.

I just recently installed a new modern furnace into my 1977 Scamp 13'. From my understanding of things, the Boler 13' is basically identical to my older Scamp. It did take some cutting and gutting, but It came out working pretty well. The Suburban NT16 (Front Discharge Model) Should fit into yours as well. I had about 1" of space left over in the rear of the unit, so it is pretty snug. My Scamp was original equipped with an old gravity furnace. It was no longer in it when I bought my trailer. It was located just below the sink on the left side. I installed a power center in that area. Also I wanted the furnace discharge a little farther from the dinette when we are sleeping. I opted to mount on the right side under the sink. I had to cut the opening wider to fit the unit in. I built a shelf to support it. The rear of the shelf is sitting level on the wheel well. Because the wiring and controls are located on the right hand side of the furnace, I cut some notches in the shelf, one for the gas line and one for the wires. On the NT12 I installed, there is a safety switch located in the same hole that the wires come out, on the right side. Because that side of the furnace was going up against my fridge. I cut the notch in the shelf wide enough that I can slip a finger up in there, and get to that switch, if I ever needed to. The model furnace I purchased was a side discharge that is convertible. The dimensions are all the same but the location of the controls I believe are a little different. Here is a link to the thread where several are discussing this installation.

Feel free to ask more questions.

Hi David,
Sorry for the slow response on this... and thank you very much for providing additional info. Our furnace would need to be installed in the exact same place that you've installed yours (right hand cabinet under sink). This looks very promising.

My worry is that your Scamp and my Boler may have different cabinet depths. My cabinet is only 18 inches deep. Do you know how deep your Scamp cabinet is?

Also, did you install a second battery to help run your furnace with? I live in the Yukon and our campgrounds are gorgeous, but they don't provide electricity.

Thanks again for your help!
