What furnace do I have & how do I turn it on?

[brownrecluse]

Another newbie question that I can't seem to find using the SEARCH feature.

I'm trying to figure out what works and what needs replacing in my 1975 Boler.

Are you able to determine which model furnace I have from the picture below? There's no tags or marks or anything on it. Once I know what I'm dealing with I might be able to find an answer online. Or...

....the obvious follow-up question...what's the procedure to get it fired up? Step by step would be great. In my limited use of RV furnaces they were pretty self explanatory. But this thing has me stumped. And I don't want to blow myself up unnecessarily.

Thank you for any help.

With a 35+ year old heater, before even trying to light it, I would suggest having it checked out by someone that knows heaters and has a leak "sniffer".
IMHO: That may well be a carbon monoxide leak waiting to happen.

The instructions are In the document center.

If you can, remove the furnace by drilling out the rivets and check both the intake and exhaust pipes for wasp nests. I had one in each.

This will also allow you to check the combustion chamber for cracks and rusted-through areas.

Then, take the burner apart and clean the orifice and burner slots.

After that, it should fire up using the instructions on the document above.

Be careful, and if yo're unsure of your furnace abilities, have someone check it out to make sure it's safe. (I'm in MN if you're near enough to stop by for a check.)

And if you decide to get rid of it and replace it with a modern one, let me know, I'd love to have it for spare parts.

Thanks people. You've helped me realize that I should let the pros check this out. I just moved to Reno this week so I'll track down a shop. Good news is that I definitely don't need the heater for a while. If its time to replace it, then I'll contact you about salvaging parts. Thanks.
