My stove is side loading with no glass, and will accept a 30" split. I'm not clear on the effects of the fire brick lining. I can line just the bottom, the bottom and one vertical brick high up the sides, or the bottom and all the way up the sides. The other variable is whether to use full bricks or splits on the sides. I don't want to burn out the sides of the stove, so I believe I would want to line the sides partway up with splits at a minimum. I presently have it fully lined with full size brick. What are the tradeoffs? Thanks.
