About 2 years ago Gene barrow & I adjusted my Solair mixture for a howling issue. Seemed to repair the noise. Last year at ES in Milan, Mi it started howling again while we were having a business meeting. Was loud enough to hear in the building. Switched to elec heater and adjusted it again when I got home, no howling. Since then Cat got us a Carbon Monoxide detector. Last weekend in N.C. I fired it up (first time with the detector) and after about 3 cycles the detector started barking. I also noted that after a few minutes of running the furnace burner sound would randomly change slightly. So I`m thinkin maybe the heat exchancer has a break in it allowing the mixture to change and allowing burnt gas into the coach air flow???
I go to the Avion with the same furnace and remove it first to kinda see what I`m gettin in to. I found the exhaust vent to the outside was rusted to the flange solid. I had to break the weld on the plate to get the furnace to slide out. I then cut a groove in the remaining coller on the bench with a dremmel and took it off. The coller covered the slot vents in the exhaust pipe cover. It was slid on at least 1 1/2 "
When I went to take the furnace out of the Crestmont I took the outside vents off to see how bad they were and found the flanges were not even touching the furnace, no way they would slide on the intake and exhaust pipes. They was 1/2" between the pipe end and the outside flange. The outside flanges were pristine. Looking inside the Crestmont the furnace is under the rear dinette seat and is pushed as far outboard as the interior wall will allow. I can look behind the furnace and see the slots in the exhaust pipe cover inside the coach. They were stuck in the holes in the wall but not deep enough to catch the outside vent flanges. I did put the furnace out of the Avion in but it would not fire. Maybe I didn`t hold the reset button long enough but I did start smelling Propane so I`m thinkin Ignitor maybe. I`ll start with that tomorrow..
I do not know how long this carbon monoxide condition has existed, since new, or 2 years ago with the first howl, or just this trip.
My alternatives to fitment are to cut the bottom of the curved wall board inside the dinette seat and extend the gas inlet to get the furnace 2" closer to the outside wall or take the furnace to the muffler shop and get 2" extensions made. I`m thinkin muffler shop.

Now the QUESTIONS.
Could the misalignment of the exhaust and intake pipes cause the carbon monoxide detector to bark?

Can I put small air pressure maybe 15 lb on the exhaust outlet and soap the out side of the heat exchanger for bubbles on the bench?

I`m thinkin I got 2 problems.

Chuck, now we know why you seem to be so "loopy" sometimes. You have been breathing gas fumes. Laughing
Nothing hear to offer, just could not hold myself back.

Chuck,

The PO of The Blue Streak removed the furnace completely and the furnace in Double Trouble has been replaced too, it's got one of
these in it:

http://www.adventurerv.net/atwood-excalibur-furnace-8531iv-30000-btu-amp-p-3840.html

What I'm about to note is a SWAG. I went to Bdub's website and found the manual for the Solair and guessed at it's dimensions (12"
tall and 6" deep). That would make the side plates of the furnace 72 square inches. Multiply that by 15 and the amount of pressure
on each side plate would be 1080 pounds. I have no idea how the furnace is built and therefore I wonder if it can take that kind of
pressure.

If you want to leak check the furnace I'd bring the pressure up slowly and not go above a couple of psi.

Regards,
Rob M.

Rob,
Very good point! I would suggest even less, maybe 1 PSIG or even down into IN/H2O range of 15 to 20 IN/H20. (1 psig = 27.7 in/H2O) You could balloon that heat exchange to bursting.

Thank you gentlemen: I was going by the gas pressure of 11 in inlet pressure, but I see that is a totally different apple.

From what I have read here over the years I am of the belief that the Solair furnace was a bad design to begin with, and didn't get better with time.

Replace it with something of a better (safer) design. New would be better than used.

As you have found out (luckily before your death) a good OPERATIONAL CO detector is a must if you use a furnace, propane refer or generator.

I just replaced the combustion blower on my home furnace.  On it, the blower is a scavenger instead of a pressure blower - it sucks combustion products out of the burner and blows them overboard.. a much safer design.  If the furnace develops a hole in the heat exchanger, you'll pull house air out of the system instead of blowing combustion products into it.  Are the newer RV furnaces designed this way?

Johnny: I know your RB Crestmont has a kennel cage instead of the dinette but is your furnace still there?? If so you might check to see if it is mounted to the outside vents properly. If so was the wall board cut?? Look behind it pls.

Chuck, I have a great no nonsense way to check for leaks.
Back in the summer I put in a new gas two burner stove top for Teri. I kept smelling gas everytime I fired it up. Sprayed everything with soapy water, nothing. Went in the house and got Teri's Bic Match. Teri, "what are you going to do with that?" "Nothing, will bring it right back". Came back in with singed hair on my arms and a burned spot on the wood under the sink. Had my Halon fire extinguisher handy and put the fire out quick. Found the leak. I had forgotten to tighten a fitting? Laughing
Now, you see why life is good? I am still alive.

Actually it currently has a crate that sits beside the furnace - I'm looking for a dinette :)  But, the furnace is connected to th vents, and it looks to be properly connected.  I'll cast another eyeball on it this evening and make sure.  Out of curiosity, did Norris call them 'crestmont'?

Yeah, a match or Bic will often find a leak that's not even up to bubble pressure.  I wasn't smelling propane, I was smelling combustion products.  I'm going to do the check C suggested this evening.  At a glance it looks connected like it originally was... but a closer look may reveal something different.

Boy I don't think I would want to try to sleep at night with a heater that could set off a carbon Monoxide detector. A new one at any cost would be on my list for repairs at the top.

OK then that's the deal.  I wasn't sure.  I knew Norris was the upfitter - it doesn't say 'Crestmont' on it any place.
 
Thanks,

I wouldn't like the big "MIDAS" either... maybe why that was not the normal Crestmont decals.

Seems 1975 was a year when the transmode upfitters were still shaking out. (This seems to have also continued into early 1976.) Most of the low volume transmodes, upfitted as actual MOTORHOMEs, came from this time frame.

All of the Norris upfitted 23 foot coaches I have seen in person or pictures, look exactly like the 23 foot coaches labeled in the brochures as Crestmont by Midas. This is a 1976 brochure: <http://www.bdub.net/publications/1976%2023%27%20Models/1976_23%27GMC.htm>

Something tells me that if your "Crestmont like coach" is NOT labeled as Midas upfitted, it would have a Power Level system. Making it 1975 or early 1976. (There were not very many 1975 23 foot coaches of any type.)

Mike,

I wonder why Avion was not in that series?

"Someone" "told" me that Avion built 137 coaches in 1975, I don't know if that was:
A) 23 foot B) 26 foot C) Total of both. I suspect it was C).

IIRC David Greenberg "told" me that there were only a handful of 23 foot Avions on the registry.

Regards,

Sir: acording to the records the Crestmont was 1976 only and all 23s. It does have the late windows and HEI but has the early stainless/rubber waist band. Mine does not have any leveling valves at all. Has a blank GMC plate where the valves go. It stays in travel all the time. I believe Johnnys coach came without the valves also but were added. http://www.gmcmhphotos.com/photos/crestmont/p41180-crestmont-dash.html

Sandy Shullers 1976 23' Crestmont is a side bath and has the early valves. Sandys coach has a dash plate with Midas on it and shows a 26' coach. My theory is the rear baths were outfitted by the Norris facility in Bean Station and the side baths were outfitted in Elkhart, In the Midas facility..
http://www.gmcmhphotos.com/photos/member-galleries/p40216-crestmont-glove-box-ba.html

I ran into a feller here local (45 miles from Bean Station) and he says he use to work at Norris facility when they were doing the interiors on the GMCs. He swares there a few special order coaches that had Cadillac motors in them. I have no documentation of this, only the word of an old crippled up biker that I have only met once. I tried to argue the 455 only but he held his ground and seemed sincere.

If anyone else has a 23' rear bath Crestmont with a Caddy in it, it possibly could be factory. Please contact me.

Cool, I had heard that the "Power Level" was "an option" and the base model had automatic ride height but no valves for manual leveling at the camp site. (Seems Norris/Midas was a bit cheap... Twisted Evil )

I have seen a few specific instructions in the maintenance manual for coaches without Power Level.

Rob was talking about this brochure: <http://www.bdub.net/publications/1976%2023%27%20Models/1976_23%27GMC.htm>

Most likely the reason the 23 foot Avion was not in that brochure was that it was for 23 foot GMC's built in 1976. All 23 foot Avions where built in 1975. (And almost all the 26's as well.) GM most likely already knew that Avion wasn't building any more when they produced the "1976 brochure" most likely created in late 1975.

As far as how many 23 foot Avions were built, I understand it was between 10 and 15. While a small number, it is a rather high percentage as there was only THIRTY SIX 23's built in 1975. That would be about 30% Avion. (For info: That 23 foot Avion I noticed a while back on Craigslist in SC was listed in the registry as a "1975 Birchaven." Most likely due to the fact that it had 1978 Birchaven decals on it!)
