Hello all... I will be buying a Hearthstone Homestead in about a week or so. I have been looking things over to get an idea about costs and materials (we will install into a fireplace by ourselves), and things look pretty straightforward- except for a four inch damper plate that we need to pass the six inch flex through. I'm always excited to break out the Porter Cable sawzall, but what is the best way to handle this? Also, any Homestead users out there? I'd like to hear your thoughts about the stove.
