Last year I got a lot of great advice on my new insert...helped a lot. Now as 2nd season approaches I have some more 1st time questions. I took all the fire bricks out this summer and vacuumed out the insert as best I could. Replaced (obviously) the bricks and consider myself good to go in that regard. I still need to sweep my chimney liner which I will do before my 1st burn. does anything else need to happen to the interior of the insert besides a good brick removal and cleaning?
