I have a Harman Accentra insert that was installed in early spring. I've heard varying reports as to how often to clean the stove. Some people go so far as to suggest that you should scrape the burnpot everyday. So what is a realistic schedule for cleaning? I've been cleaning mine a lot, but it's been easy since by the time it was installed we did not have to run it too much. I'd rather not take the stove out of service for a daily cleaning if it's 5 degrees out. So how many bags should I burn before cleaning out the stove and/or scraping the burn pot? I want to err on the side of caution, but don't want to do it if it isn't necessary. Thanks!
