 Re: Second broken Flue Tile
After reading this thread I am concerned about my terra cotta flu and the future of it once I enclose it. Today I cut fire bricks to use as my transition between vent and flu. I plan to mortar the bricks together with refractory mortar, then mortar the flu to the bricks. My chimney will be 3 2 foot sections of clay flu because it has to be higher than my 10 foot high pergola. The sections are so heavy and I'm concerned about the weight. I'm also trying to figure out a way to enclose it with the space allowance around it. It's so close to the front of my oven and doesn't allow for a gap around the flu and then block to enclose it. I tried to attach pictures but I'm having a hard time figuring out how to do so. Once I place the flu on the fire bricks there is only 2 inches of space to the front wall if the enclosure, not enough space for the 1/2 inch air space and a brick or block. Any ideas?
Do I attach the sections of flu liner with refractory mortar only or it there some kind of heat resistant tape that holds them together? I suppose if it's all level and plumb it shouldn't go anywhere but it still concerns me that just a single layer of mortar is holding these big sections together.
