Suburban NT32 C age by serial number?

I purchased 78 Argosy. More work than I thought but I'm committed...or should be. I just replaced all copper lines because they burst do to freezing. New regulator, check valve, drain valves, pump, shower valve, faucets and water heater.

The next order of business is the propane system. I tested the stove and water heater and they worked fine but the furnace would not light.

Existing Suburban NT32 C with serial number 0570857. I don't think they make the 32 any more but it looks like it has not been used much. Is there a way to find out if it is the original or replaced at some point?

Another question and I have tried to search is, does it need 12v power just to light the pilot? I understand the power and fan must come on to activate the sail switch which opens the gas valve to the burner. But just for the pilot?

Testing for leaks if it runs. Close all the doors/windows and install a carbon monoxide tester or two? Is this method acceptable?

In reading some of the threads...Its just safer to replace it. Yes, I'm sure of that and if I need to remove it and open it up to check for rust and pin holes, I may as well replace it.

If it is a pilot light model, it is most likely original, that is 40 years old. Those Suburbans were also subject to safety recalls. No recall parts are available now.

Your life is worth a new furnace. I cannot recommend anything but replacement.

Thanks for the reply. My life may be < a new furnace, my wife's may = a new furnace but our kid....priceless. (Hoping the wife doesn't read this, LOL).

What is the replacement? NT30 or the NT34? Will it still work with the NT32 existing vents out the side?

The NT 30 will be fine in capacity. In general, the vent system will be the same or similar but may require you to build a platform to get the new (generally slightly smaller) furnace to fit where the existing vent holes are now.

idroba,

Thanks for your replies. First of all, I probably would not be able to sleep knowing the furnace could kill. If anyone got ill or worse, I would never forgive myself. I have been researching a replacement and I will get the NT30.

Now, I may change the kitchen counter top and so on.

I twisted the top on my can of worms......worms are pushing out.....to late to close.

I forgot I ordered a Progressive dynamics PD9260C, just arrived. I'm leaving the 110v alone but redoing the 12v. Well that's the plan for now.

The new PD converter/charger you have ordered and now received is a good one, maybe even overkill for your needs. You may need a new fuse box or panel also, I forget what Argosy put in your rig.

Changing the countertops is always a good project too, it updates the color and texture of the original. And you can take the refrigerator panel off also, and have it match the color of the countertop. Then while you are at it, maybe a new sink, and faucet.

And on and on and on.....LOL.

Just an update on progress. I allocated my Saturday to remove the NT32 but I was done in less than an hour.

78 26' Argosy. Remove oven, remove the 4 screws that attach it to the floor, remove the two middle (long) screws on the exterior vent. Disconnected the electrical, push to the side to gain access to the gas connection. Remove furnace.

Tracking number shows delivery on Wed.

Looking for a counter top. The Home Depot has premade tops but with some online research they seem to be a bit narrow. I really don't want to replace the cabinets because they are in acceptable shape. I guess I will keep looking.

The way the cabinets are built surprise me. Wow! I don't think you could make it any less structurally.

The cabinet build is all about saving weight and, with the countertop attached is not as flimsy as it looks.

I know you are thinking new countertop but I thought I'd suggest you consider doing what we did; we resurfaced all the horizontal surfaces with Marmoleum sheet flooring. Been a year and it still looks great and cleans up with a damp sponge. The only thing you really have to worry about is setting a hot pan down on it.

I will check into it. My top has a back splash and a curved radius at the front edge. Will the sheet flooring follow the contour of the rolled edge?

Thanks

If your countertop has a continuous backsplash and a curved front edge it is not the original Argosy one to begin with. The original ones had a separate square edge backsplash and a front which was square and trimmed with a metal edging. My '74 Argosy had already had the countertop replaced with a pre made Home Depot type replacement when I bought it. When I wanted to change the sink with a different size one, I simply got a new piece of HD countertop with laminate that I liked and replaced the replacement. It is made of particleboard and is heavy, vs. the original 1/2" plywood counter, but there is not a lot of it, so the additional weight is minor.

The cabinets are very lightweight, and were built on/into the trailer at the factory, so have many different attachment points and interior parts. The workers sort of built them custom for each unit, I suspect.

The Argosy was the experimental line. Airstream used them to try out ideas and materials. Thus they are often different from one another, and from Airstreams of the same era. The factory workers (at least in Ohio) were in a different building from what I understand, and may not have been as skilled and well trained as the Airstream folks.

So, you never know what you might find in an Argosy, factory or what a previous owner has done.

In our '76 Ambassador the counter is 30" wide and most preformed counters are made for 24" base cabinets. Our counter has a separate flat 3"x1" approximate back splash with a vinyl bead between the pieces.

On the subject of countertop, my 76 Argosy 26 also had the same style as yours. I was having the same challenge as you , finding that the Home Depot counter tops were more narrow than the original Argosy. After looking around for solutions and not wanting to have a custom made top , I recalled a prior post on the subject. The solution was to cut back the cabinet face where magazine rack is by the door . That allows the cabinet to move closer to the wall and you can then use in stock counter tops. The drain plumbing may need some slight mods . Can post pics if needed .

The counter top seems to be 3/4 plywood with a orange color plastic laminate, not sure if it is original or not. I can picture reducing the size of the cabinet to fit the prefabbed top. Did you need to reinforce the new top to support the weight of the cooktop/oven? The prefabbed top is made of particle board and is thinner. This seems like a good option for me. If you have pictures that would be great.

I cut off the rounded front edge and edged it with aluminum "diner style' extruded edging. The back splash on mine is a separate piece so I painted it a complementary color.
