Hello everyone I want to purchase the 55-TRPEPI at this site, http://www.amfmenergy.com/55trpepi--epa-certified-pellet-insert--2000552000.html, but I am unsure of it being able to fit based on the owners manual. It is kind of vague. My fireplace measures 34 inches front width and the manual says minimum 36 inches. However, based on the diagram in the owners manual I am unsure if that means total fireplace width or if they are referring to just the firebox. I find it really hard to believe my fireplace, which is big and old would not be big enough for this model. Any insight? Thanks guys.
