I'm giving up on trying to replace/repair parts of my '69 Shasta Airflyte. Instead I'm pulling it apart from the outside in.
I'm working on pulling the skin off of the street side. There is a metal multi-layered vent that I can't remove (so can't remove the skin). It's part of the Glen Aire Duo Therm heater and connects via a rigid metal pipe to the heating unit. I've removed every screw I can see, but it's all still firmly attached.
So what now?

The inside exhaust pipe is about two inch diameter. That is what is hanging you up. These are fitted together and not screwed together. The rust and corrosion over the years make it quite difficult to knock these pipes apart. They take a bit more than the average "gentle persuasion" to take them apart. That inner pipe is press-fitted into the flange of the outer vent...making it seem to be a one-piece unit.

Good luck on the removal, sorry I can help. Mine is a different model.

Super old thread to dredge up, but I am at the same spot. I am getting ready to take the skin up on my 66 Airflyte and today was a bit curfuffled at not being able to remove the exhaust to my furnace.   Anyone have tips or tricks to get it off while leaving the furnace intact? |

I tied a ratchet strap from the furnace exhaust to the neighbor, a 57 Shasta...  And surprise!  I've cut them, ripped and torn at them. The above worked. Perhaps being a younger 71, the exhaust wasn't quite so frozen in time. Good luck! |

Thanks for the pictures. I have a fence pole close enough that I will be trying your trick this weekend.

Well ratchet and yanking did not work. I was afraid that I would damage the skin or furnace if I went to hard. I am going to cut it off from the inside, right after the 90 degree turn the exhaust pipe makes. Should only have to have the pipe extended out again and could have that fixed when I get it in for the LP to be looked at.
I'll add some pictures of the process when I am done.

Ten yours looked so much nicer than mine.  Of course after I cut halfway through the extension it loosened up.  And at one point some mice made a home in whatever this piece is called.  I am hopeful that when I finish up and bring her into the LP guy he is able to put a new extension on. |

These old heaters are a PAIN to remove and often don't work. I replace with a Wave 3 most of the time. If they work, they are great heaters.

When mine did come apart, it looked a lot more like yours than you may think from my photos. I cleaned it up some before I remembered taking the photos of it. Mine had a nest in exactly that same housing as well.
Once it was out, I found a lot of rust around the burner chamber, and some really thin spots. I have already disposed of the heater, but kept the vent and straight pipes. Even if a new style heater vents differently I will still have the hole in the side wall to contend with, and the original cover makes perfect sense for dealing with that. If yours checks out as okay to burn, I would think replacing the cut pipe should not prove to be too tough a task.

What do you do with the old exhaust hole and cover then? Cover it from the inside and put back old covers for look? I am hopeful the furnace still works, but if not the Wave 3 looks to be a great option that is not too expensive. |
