Suburban furnace operating

[sm350bl]

Yep, that was me. I forget if you have a dinette or club layout. The only thing that was hard was that it was difficult to reach the fasteners holding the forward club chair base in place. I could tell it was hard originally too, because they were all slightly slanted due to the very tight conditions between club base and furnace. Chinook even lowered the floor there slightly! I bet it's much easier with the dinette base.

But all that said, I think it took me less than an hour or two.

I never put it back because, 1) Glorious storage, 2)Noise, 3)Amp draw, and 4)inefficient propane use. However, I'm getting lazy and miss being able to reach out from my pillow and hit the thermostat (as I could do in my camper van). So I think this winter I'm going to put in a Propex furnace. (Lower amp draw, more efficient, smaller, and I can run longer ducts so no more icy bathroom.)

I do have the dinette setup, I didn't realize the exhaust outlet was so long and glasses in, I may have to remove the divider under the seat to allow enough room to slide the unit back enough to clear. So far we do mostly dry camping, and the GF I swear is part reptile, she is always cold so having a furnace is a must for us. I may look into a more modern unit that would be compatible for the setup that may be more energy efficient, But at the very least it needs to come out and get cleaned and I need new ducting tubes........

Are you saying you think yours is "glassed" (as in fiberglassed) in place? Mine was not. It's a standard metal inlet/outlet "schnozzle" that comes from Suburban, and is fastened to the outside of the shell with screws (from the outside), along with some bedding compound to keep leaks away. I removed mine and re-bedded it (I kept the outlet schnozzle there for the time being).

But yes, the top pipe is longish. Since I had removed the whole club base, I was able to pull the furnace off without much trouble. Not exactly sure how the dinette base will compare.

Ahh ok. maybe I didn't look closely enough at the picture. I thought that long exhaust pipe was glass into the body, but if you undo the grill on the exterior that pipe can pull through is what it sounds like? Just putting this together in my head.

Yes, that's it. Whole scnozzle comes out to the outside. Since I wasn't putting the furnace back at that time, I just cut out some metal sheet circles and butyled them in place on the inside of the tubes.

I see now what you were talking about. I removed mine from the inside like you did. I almost took the inlet/outlet out of the body, but I needed access to the space where the furnace was anyway so just did it that way. I did have to remove the partition between furnace and under seat storage area to give me enough room to pull the furnace out of the exhaust pipe. I ended up taking my furnace to work with me to tear it down. I was going to take pics of this process but it was so impacted by mice i figured nobody wanted to see that. I was contemplating chucking the whole unit and replacing until I looked up what one cost. Figured for 500 bucks Id give it a try to clean it up. Luckily the furnace have virtually no hours on it and wasn't all rusted up. I did remove the furnace from its metal box and chemically cleaned and brushed everything.Pulled the cover off the intake and cleared away the mud dobbers nest and tried lubricating the blower motor shaft. ( I figured it was a sealed bearing/bushing but a lil extra lube on the outside couldn't hurt) I can provide details how to disassemble the unit if anybody ever wanted to know. Its all back together now and no mouse smell at all and its been sanitized so I think im going to give it a run. Will replace all the ducting and flanges as well. Been waiting for some rv/boat chemical odor eliminator to show up so I can finish vacuuming / spraying and maybe steam clean the carpet in the furnace area before replacing back in and testing.

I forget which model you have but it must be the dinette? (cause you mention a partition). Just out of curiosity is the floor not "lowered" under the furnace in that model? I guess it wouldn't have to be since you aren't trying to have both a seat box and a separate upholstered chair (as in the club lounge). Also in the club lounge the carpet is removed in the "lowered" area where the furnace sits (another clue maybe). Always interesting to know the differences.

Sounds like you did a thorough job on the furnace. Bring on the heat!

("Lowered" meaning that about half the floor plywood is routed out under the furnace to make the it sit lower and clear the club seat base box.)

Yes, correct, I do have the dinette model. and the floor is lowered under the furnace. Ill go ahead and post some before and afters. I didn't get any pics of then I have the furnace removed from its box, but it does slide out for servicing / cleaning or getting to the sail switch. I am happy to report that so far the furnace passes the smell test. it smelled something awful before, but after all the scrubbing and disinfecting, I feel confident enough to try it out. Gotta have heat, we mostly dry camp and the gf is cold ALL the time. I have also hid the fact the furnace was so impacted with mice cause again she would freak. ( a real camper she is) haha, I also ended up just snipping the wires that came right out of the box vs undoing the factory crimp joints and un-looming. This was my solution using weather proof plug type connectors so in case I need to remove again I can just unplug the unit. These connectors are shielded on both ends.

connectors, the black looking wire is the other blue I just marked with sharpie to keep track

I see how that works in the dinette now. How nice that you can remove the seat. Can't do that with the club base box BTW, for anyone with a club chair layout, I looked at my photos and I see the first thing I did was undo the base box from the wall and floor (torture). Then I tilted the whole base and chair forward (there is a thread on it way back when). Dinette looks nearly roomy by comparison (for furnace work).

Good idea on the connectors.
