how much pipe is up in the attic. Does it go strait up or is there a big offset from where it comes up an interior wall?

how much pipe is up in the attic. Does it go strait up or is there a big offset from where it comes up an interior wall?
Its cold today, so I made a funny illustration of my HVAC issue. The yellow stars represent lil snow crystals produced by the exhaust that plug up the annulus of this concentric exhaust contraption and causes the furnace to shut down.
You bang out the end cap thinggy and she fires right back up...

Something like this would work too for insulation.

I have seen a commercial HWT that was connected opposite - exhaust was on the intake side. Intake was the straight line & sucked in a birds nest. Just another thing to consider while you are in there.

It looks like the exhaust may already be insulated. But also looks really easy to do a two pipe system in the spring.
Also, Any way I could thaw this from the attic if it happens again this winter?

Pull the cap off.

I attached a pic for anyone interested.
It's not so much a cap as a divider. If you cut the cap off there is nothing to separate the intake air and exhaust air and it probably wouldn't help a frozen exhaust anyways, maybe if it was the intake freezing

You might be pushing your max distance or footage of venting/elbows for that furnace.
2 pipe set up might still freeze with 15 feet of pipe through the cold attic
A guy could cut the pipe and knock the ice block out then glue a coupling back in or a tee with a clean out cap.
(Prob not technically legit but better than a death climb on the roof!)
Obviously not after it’s already frozen but as prevention for future freeze ups:
from the attic drill a hole in the intake pipe, tap it to 1/2 NPT for a strain relief connector to seal into. Then fish a piece of industrial grade heat trace up the intake and loop back down the exhaust. hang 15 feet down into the exhaust tube.

My mom and dad had trouble with there stacks the one winter. Dad had a smashed elbow and mom had a broken femur. I was over at their place and I just wrapped the stacks with insulation solved the freeze up issues for them.
Last couple days, this thing plugs up 10 times a day with snow and its not even snowing.
Might be switching it out for low efficiency furnace...

If you're getting up there anyway, what about wrapping some heat trace around it? Probably not a permanent solution but will get you through the winter til you find one.
With yours being vented out the wall you have something strange going on.Last couple days, this thing plugs up 10 times a day with snow and its not even snowing.

Is it facing up wind to the NW?
No its pretty sheltered, too sheltered i think.
It is under a deck, looks like when i used to hot box the car back in high school lol
Im going to fix it in the spring, but i want to go sledding and dont want the heat to be out for a month while im gone.
Was thinking about heat trace, not sure if it would help me though

heat lamp shining on it
Vent is Just through the wall but trapped under the deck?
Or long run out past the end of the deck?
