I have had a vibration in my stove for a few days now. Thinking it was the rear shields vibrating, I took them off. I just wondered if it was advisable to run the stove for any length of time with the shields and doors removed? Once I can determine if the shields were the problem, I will put them back on and make sure they are damped. Oh, I also cleaned out the fines collection box while I was in there. If that doesn't fix the vibration, I will go to phase two...
