Howdy Everyone,
Last December we had the new Englander 13NC and completely new pipe professionally installed along with a new roof panel in that section after we had the chimney fire with the old box stove set up. We have DuraVent double walled insulated chimney and DuraVent double walled telescoping stovepipe. It's a straight shot pipe.

Two days ago we had a small snow storm and only an inch or so of snow on the roof. The fire was out for several hours, I heard some dripping starting and saw a bead of water running from under the telescoping part of the double walled stovepipe down the last section of pipe and onto the stovetop which stopped in a few seconds, and then within a minute I twice heard two sounds like when you see a very small stream of water run off the roof, but it was coming down the inside of the double walled pipe and landing on the ceramic plate inside the stove. I opened the door and felt water on the stainless steel tubes. I did not hear or see any more water after that but the ceramic plate feels saturated and a bit soft on one side. Two people looked at the roof and the chimney area, cone, cap etc etc and cannot find anything where it could be leaking around the chimney. It all looks great and very sealed up. We don't know where this water got in. I have two questions.. Is it advisable to start a fire? and perhaps small to dry out the ceramic plate or is it ruined? And is it possible that there is a leak somewhere that is filling the support box and then it is getting to a point that it runs over into the stainless interior stovepipe? Having water leak from both sides doesn't make sense. Their was no snow on the cap and we brushed all the snow off the roof. Thank you for any and all help.
 
Condensation?
 
Not sure about the baffle issue, but that doesn't sound too good. Can you get it out without damaging it? To dry it out.

I read here, and did it when I installed my chimney, to run a bead of silicone down the seam if the class A pipe and all around the storm collar. Water will follow the seam down and through. And don't just lay a simple bead, but pack it in good with your finger. I've had 0 problems.
 
Build a small fire for a fair duration to gently drive the water out. Small as in kindling. Duration as in an hour or two. As far as where the water is coming from? Dunno - that will probably have to be discovered by physically being there.
 
We are hoping to dry out the baffle where it is instead of trying to remove it because of how soft it feels where it got wet. Condensation was considered but on roof panel inside? or pipe? I realize the leak can only be found through physical inspection, but has anyone ever had the support box fill with water before? Not sure if this is possible, and we sure don't want to take everything apart in a Wyoming February if we don't have to. Has anyone every had a baffle get wet before? I appreciate all your suggestions and thoughts.
 
Just to double check, does this chimney meet the 10-3-2 requirement? Being professionally installed it should, but to be certain make sure that it sticks up above the roofline at least 3 feet, and additionally that it is 2 feet higher than anything within 10 feet of the chimney.

If that rule isn't met, i suppose it could be possible for snow blowing off the roof to have infiltrated that cap?

My grandmother still burns wood but only burns for a 3 or 4 weeks a winter. Even w/ a chimney that meets this requirement and a good cap, under certain conditions rain and or snow will get down into her chimney.

I cleaned her chimney a few days after some torrential rains here in September (cleaned it then because I was off of work since things were flooded) and I must have taken close to a 1/2 gallon of water out of the bottom of her chimney.

Yes, it is actually five feet above the highest point because our place is tiny and our ceilings low, and we needed this to get 12 feet of pipe above the stove. Our roof is not flat but it has only a slight pitch and our ceiling is drywall, insulation, and then the metal roofing panels on the roof joists.
 
Like Jags said. Dry the baffle in place with a small fire and it should be fine. When dry it should be back as good as ever. Just don't handle it while it is wet.
 
Thank you all! :)
 
I think I know were the water came from. If its been pretty cold there when the stove was down warm moist air from the room will condensate and freeze on the inside of the chimney above the roof line. When it warms up enough to melt it will run back down the pipe. I have seen this in vent stacks that go through unheated areas. In prolong cold spells alot of ice will form in the pipe only to melt and soak a ceiling later on.
 
hmmmmm, that's an interesting thought.... It has been unseasonably warm but a few days before this happened the weather turned colder, strong winds and snow. Got quite cold that night too.
 
One way to determine if it is a leak or just condensation would be to spray a small amount of water on the roof around the chimney for 15-20 min. If you don't have any leaks then it was probably condensation. If you have attic access it will certainly help you locate a leak if you have one. Another option is next time you have some cold, breezy weather go up on the roof and look down the pipe for signs of ice or condensation build up. Just don't fall of the roof, my my metal roof gets really slick when it is cold and damp.
 
thanks for those suggestions burlymike! :)
