I have a central boiler classic 6048. This makes my 4th year running it. I use the ashtrol everyday just like it says to do. I clean the ashes out regularly and test my water just as it says. I am having an issue with rust on the flange of the opening of the fire box. This is where the rope seal meats the flange when the door shuts.

I noticed when I go out to fill the stove that there is like black looking water at the base of the stove that has leaked through the door. I have adjusted the door cams, and I have painted the areas that have rust with a product called rustame 2 this is supposed to stop the rust. I plan on changing the rope seal. The only thing is if I change the rope seal? Will this cause the moisture to pool up right where the door is while it's closed?

I guess my question is why am I getting moisture right there at my door and nowhere else in the stove including my stack? What do I need to do to stop this? Is anyone else having this problem? I would post picture if I knew how to load them on here.
Thanks for any input or suggestions.

I would be willing to bet that the rope gasket is allowing cool air to infiltrate the firebox when in the off cycle

Its a natural cool spot on stove so moisture condenses there.. 

Gaskets may help but they run like that for the life of the stove from what ive seen

I installed my 6048 this year and had the same thing happen. Went to the dealer and the one he has at his house does the same thing. There solution was to mount the stove pitched slightly back. He said just as Scott said.

Tilting a stove back doesn't sound very healthy to have that black liquid settle into the ash near the loading door.

[Scott7m]

Hmm...  when u tilt the stove back by raising it in the front a little

the moisture runs away from the cool spot where it was formed and disappears or burns off

 

Think about it, it formed where it was the coolest, make the moisture leave that spot using gravity, then it tries to enter a hotter area where the moisture cant survive

Sounds like some good suggestions. You also might try stacking the wood in the firebox closer to the front door for more heat generation to dry it off. When I ran my Classic I stacked the butt of the logs within 2- 3 inches of that front door frame. Helped a lot.

You might also try to keep a fresh coat of high temp paint on the area being affected.

So what is the cause of the cold spot?  air leak or if as I read more than 1 have the same issue in the same spot

[Scott7m]

The cause is its right beside the door. So instead of there being a piece of steel, 4 inches of water, and then insulation that keeps cool outdoor temps away, you have a flanged piece of steel and a door.  That causes that part of the stove to be cool.  And these cool spots cause condensation.   

If you had an air leak big enough to cool the stove it would do opposite and allow it to overheat

a bit of air likely atill goes through ropes like slim said, but knowing the model its just a cool spot

I was just repeating what the dealer said. The little bit if black water doesn't bother me as long as it isnt doing the stove in. No rust yet.
