This is my first time cleaning the Progress Hybrid. We have been burning it since late October and we have a couple of days of warm temperatures before it goes back to the 20's and 30's. I just cleaned the catalytic convertor (vacuumed and blew it out with the air compressor) and vacuumed out the upper chamber. Raked all the ashes from the fire box into the ash pan and dumped it. Anything else that I should do before getting it ready to burn again? Thanks for your help
