Think my furnace is vented improperly. Need efficiecy rating

I have a RUUD Model UGDJ-07EAUER Furnace

Does anyone know if it is an 80 or 90 Gas efficiency?
Can't find anything on it anywhere. Furnace or online.

Think its vented wrong.

Have an old asbestos style chimney(:
Water dripping from pipe in attic, all the way to the basement.
I guess it's condensation.
Had to rip out laundry room plaster wall, starting
to get mold.

Any help?

Do not want to mess with that sleeping dog asbestos.
rather re-route a new flue

Thanks

Venting

It sounds like an 80% unit but I'm not sure. There should be a data plate which shows input & output.

Once efficiency is determined, we can help with the venting issue but I suspect the flue is too big for the furnace.

Looks like a fancy-pants 90% plus condensing furnace with continuously variable input.

90+

Yes indeed. Looks like high dollar stuff. No way should this furnace be vented into a chimney. Venting would likely be with PVC pipe. It is OK to use the metalic chimney for a chase thru which to run the PVC but not to vent into that metalic chimney. If the PVC is run up thru the chimney the chimney top should be sealed to prevent condensation or precipitation from entering.
