I just bought an Englander 13-NC to heat my garage. In researching this stove, I found out that there is a baffle and this stove has none. Does anyone know the dimensions of the baffle so I can know I'm ordering the right one? Some places list them for almost half of others, but then say it's a two piece and you need to order two. I'm at work right now so I can't measure, but does anyone know the dimensions so I can order one?
