I installed the 52i 2 weeks ago and have it dialed right in! I have a quick question, I plan on doing a good cleaning on it next week just to get to know it more or less. I'm not sure what tools and other tricks of the trade accessories that all should include in a pellet stove. I remember some one posting about needing a brush to clean out the exhaust and such.. any thing I should put in the shopping cart? Thanks in advance.
