Ok, so more problems with my brand new leyden. I took my uneven, not over fired, lid off tonight to take to the dealer tomorrow, and started poking around inside. I reached between the bypass damper and the stove and found a two inch gap where the gasket has sagged/ fallen off. So I don't know how long there has been a lack of a seal there. Worse, I reached behind the bypass damper and found a one inch deep pile of black crunchy stuff along the whole length of the damper that must be creosote. So I'm thinking I'm done for the year. I've got a warped lid, no gasket on the damper, unseasoned wood, and a pile of chimney fire risks. I've been studying the schematics, and it seems pretty reasonable to unscrew and unbolt the panels holding the fire brick and combustion chamber in place. Question: Should I spray the bolts and screws with wd40 or something before unfastening? How do I go about getting the bypass damper out to access the gasket?
