Hi! I'm new here and I can't wait to start heating my little cabin with my wood burning stove. I have a Glo-fire 301 I need to install. Its very small and the outlet has a collar that is about 4.5 inches in diameter. The smallest stove pipes I can only find reference to are 5 inch diameter. Can anyone point me in the right direction for an adapter for my outlet? Any and all other advice for installing a small wood burning stove in a small cabin (14x14) would be very appreciated. Thanks!
