Today had temps in the upper 50's all day with steady rain all day, inside temps mid 60's. Decided to get a small fire going to take the damp chillyness out if the air.

About 1/2 hour into the burn we heard this sizzling sound. I jumped up and heard it coming from the ceiling box. I removed a drop ceiling panel, and with a mirror and a flashlight saw just alittle bit of water sitting in the ceiling box. I think when the pipe at the ceiling box hit 200+F, the water simmered.

Now I need suggestions....

My guesses are either condensation (temps outside rose up about 6deg) or the rain just bounced off the roof back up into the chimney flashing, any thoughts?
 
It could possibly be from rainwater running down the outside of the pipe. Is your storm collar sealed to the pipe? The storm collar is the sloped band, which gets installed on the pipe above the roof flashing where the pipe goes through the roof. I used a bead of hi-temp silicone around my storm collar to seal it to the outer wall of my Duravent pipe. Without a seal on that, you can and will get a little bit of water. That would be the first thing to check.
 
Ok thx. Will check tomorrow. I thought they put some on last year, but I could be wrong. Thx
 
I second what Scotty said, the first place I would check is the storm collar and chances are it needs some silicone. Have you seen any rust on the stove pipe?
 
Mine done that when i had my old stove hooked but i sealed the seems.

Edit. Had a little rust too
 
Not only do you want to silicone the storm collar to the chimney, you also want to run a GENEROUS
bead of silicone at the flashing cone/chimney juncture. Many times, due to the pitch of the roof, & the
resultant angle of the top of the flashing to the chimney, the storm collar does not completely seat against
the top of the cone. "GOOB" (technical term) a LOT of silicone at the top of the cone & force the storm collar
down into it if you can. Then apply another GOOB of silicone on top of the storm collar and smooth it with a finger tip.
