After GMA I went over to the greenhouse to see how the heater was doing. It still was stinky in there. I looked at the exhaust and noticed it was tilted. I went home to change clothes and also to do groceries. Had to take a bad dump as well so it was good to go home. After groceries I went to the greenhouse and raised the flue which was leaning downwards. This broke the supports off the chimney outside. After calling around for a new flue which is 7 inches in diameter, I decided to rebuild the old one. NB Handy which is out Poole Rd has the 7 inch in 26 gauge which is the heavier flue pipes. I took the burner down and cleaned the rust off it and also inspected the heat exchanger with a flashlight. Used some electric fence wire to support the flue so that it rises. I also took apart the flue to see if there was anything blocking it but it was clear. Tested it and then went home for lunch. Picked up some big washers at Ace and repaired the flue then went to the greenhouse and installed it. I also ran the generator for 5 minutes. I also verified that the greenhouse smelled OK. Left the furnace set for Big Bertha to come on tonight. After a dinner of Currey chicken over noodles we went back out at 7:30 PM. All was well with the heater. There were no fumes. We went around and lloked at Christmas lights afterward. The winner was the one on Penny Road. He has added a snow machine this year. We enjoyed the lights in downtown Apex and also behind the post office where there was a ob scene and actually a line waiting to see "Santa".
