Customer Question

Before replacing the following parts: 28-10400018, 27& 39-154401 in my Jotul 600, I caulked or re-caulked with furnace cement joints in the stove, and then installed the new parts.
I am now having a problem with the draw on the unit and am unable to get a fire to stay burning as it had before the caulking and new parts where installed and I end up with partially burned wood.
Are there some joints I should not have caulked? Any suggestions on what I may try to resolve this?
