Safari furnace repair

I am working on a 64 Safari w/ the original ducted heater, are any parts avail. for this unit & is it worth fixing? when I turn the thermostat on a solenoid makes a buzzing noise, but the fan does not come on.The propane is not on @ the moment.....Dont know if that is causing something not to kick on the fan?

Troubleshooting the Furnace

If you are familiar with the furnace, by all means take it out, clean it, test it on the bench, check the combustion chamber for holes--(warning leaks can be DEADLY). It might be a good idea to have a professional tech look at the system. Or a better solution, chuck it for a new one. I would save up for a new one; better than waking up DEAD.

The heater in my '64 was an incomplete pile of rust. It went straight to the trash. Do a visual inspection and if everything appears to be solid, then you can make a decision to test/repair if able. Otherwise it would be safest to scrap it and get a replacement.

PS. let's see some photos of your airstream

Hey Cochise,

A 40+ year old furnace that probably started rusting from day 1 is not the best candidate for a re-build.

I would invest the time and dollars in a new, more efficient unit (with warranty) and you'll also be able to sleep much better knowing that it won't be leaking carbon monoxide thru some little pinholes in the combustion chamber that you might have overlooked.

Better to spend a few extra dollars in this area. You'll be happy with your decision

Don't even try to fix that furnace, that was made International Oil Burner.

There were a long list of modifications to them "when they were new."

You will find the insides to be a rusted mess.

And by the way, they are famous for exploding when you try to light it.

Your local RV supply store (even though they might be a little more expensive, your business will keep them there and they'll still be there when you really need them) or as last resort.....Camping World or any of the internet sellers like PPL motorhomes.

perhaps lew can correct me if i am wrong, the rule of thumb for sizing furnaces is 1000 btu per foot of trailer.

John,

Close enough for Airstream work, factoring in a normal winter.

If temperatures hang around zero or less, then additional BTU's from the AC heat strip, or from a electric heater will be needed.

Andy

Question Replacement ?

Lew, Andy,

I have removed and will be replacing my unit as well, (although with recent temps here in GA in the triple digits it has been pretty low on the list ) can you reccomend a direct sizing replacement for a 64/65 model Safari or will it be like everything else and turn in to a custom engineering job ? Mine is 22 footer, not sure about Cochise's.

Here is a pic of my furnace before I pulled it out. I could get the measurements if that helps.

I too would be intrested in knowing the sizing... My 62 Overlander has that exact International ducted furnace and I see a bunch of rust in there. Today was the first day I testes things out. The only thing that didn't work was the furnace... smell gas when I try to light her but nothing happens. I would feel much better having a new furnace. Can the vent stay the same? Nothing says vintage airstream like that huge diffuser hanging on the side. You can look at my photos at http://www2.snapfish.com/thumbnailsh...4/t_=101036844
