Any one else have this insert im looking to compare notes.. I burned 7 face cords through it last winter the wood was mixture of hard woods at 15 to 18% m/content with a 5.5" s/steel liner 20' long .. I installed the whole job my self from top to bottom I could not use a 6" due to inside chimney restrictions so had to go with a 5.5" inside dia is 5 1/4 just looking to see if the amount of creosol I have in my clean out is normal I got over a gal of small dust and crystals from pipe and stove combined
