Please people, I'm not an idiot, nor do I have a death wish for myself or my children, please minimize the histrionics.
As they said in my youth, save the drama for your mama...
#1 - I bought an infrared space heater last night at Lowe's to use in the basement and maybe other places for supplemental heat.
#2 - I found wood stove repair products at Lowe's also, a silicone caulk good up to 600 degrees that should allow me to make the loading door airtight, and a cement & mortar product good over 1000 degrees (suitable to fix fire bricks) which SHOULD fill the cracked & missing weld spots that prevent the unit from being airtight. I will not use it again until I can make it airtight, and then only under test conditions until I can safely starve a fire and properly control the burn by controlling airflow. No more smoldering embers stinking up (and poisoning) the house. OK?
#2b - Yes, when I am working again, I will call a chimney sweep, but it is flowing fine for now. when it dries out I will attempt to open the cleanout and check the pipe with a mirror and flashlight...
#3 - There was some sort of an inspection in the past.The widow told me specifically the metal plate above the horizontal pipe was mandated in some inspection, after which they got a clean bill of health.
This thread has been VERY helpful, I have learned MANY things, I hope to learn many more as well.
Please lets keep to the engineering side of this.
Thank you all again
David
