I have model TR009. Do we leave the ash door in while burning or do we burn with it out?
No, you should leave the ash clean out cover in the stove while burning. Please see the following from your stove's installation instructions: "DO NOT LEAVE STOVE UNATTENDED WITH DOOR OPEN! Except while tending the fire, operating the stove with the feed door open or ash clean out cover removed may cause over firing resulting in unsafe operating conditions."
