I installed new 5/16 gaskets in the doors but in testing with a light inside stove I can see light leaking perhaps 1/16 at the top curve of the door. Do I reinstall with 5/16 or with 3/8 or is there a patch possibility? Or should I be looking at a door adjustment?
 
Here are some photos of the old door gaskets and the new ones (which leak light) Do the old doors have bigger gaskets or is it just my imagination? The 5/16 I used are according to the owner's manual I found on-line. The new ones are on the left.

Check for slight door warpage with a straight-edge. Was the replacement gasket an OEM from VC or a hardware store equivalent?
 
It was a hardware store equivalent. I don't know what the original gaskets were but from the pics they look like they were not strung correctly on the left door so perhaps they were replacements. Should I go with VC gaskets or just order 3/8 from amazon?
 
I got my gasket from Mt View Hearth Products based on the model 1910 I assumed it was a VC gasket. The door is curved slightly by design I can't really get a straight edge to lie flat but both doors are the same and seem to be cast that way. When I shut one door at a time they fit snug but when they shut together there is the 1/16 gap.
 
trick with rope braided type gasket is to bunch it together not stretch it out or pull it taunt as you install it.

That might be part of the issue. Door gasket material should never be pulled or stretched to fit.

Mt. View is a reputable seller. The fact that each door individually is sealing ok hints at something binding or slightly offsetting a door when they overlap. I am wondering if a very thin washer on the lower hinge pin would make enough angle change to get the offending door to close better at the top.

I have a related question. I have a P43, and I am getting a leak over the glass where the "factory" ends meet. It appears they have some premade 3/8? rope gaskets made that have been joined with some white sleeve. The length is about 2 inches, and that is where it leaks.
I guess that material being flat is not able to make a seal. I tried pinching it to make it stick out more. I don't know if it is done that way on new wood stoves?

I added a washer this morning on the right had door and it helped. I am down to just a pin prick of light leaking which is only visible under close inspection. Perhaps it is good enough?
 
Good to know it helped. Double door sealing is trickier. Most companies have dropped them. I would try it out and see how it performs.
