I have an older squire free standing stove, it draws air from inside the house for combustion, which makes the other rooms colder, my idea is to drill holes in the sides, and into the fire box, and route 3 inch exhaust pipe through the outside wall with shutters to control combustion, i will be welding the transition pipe onto the fire box, so i can remove the pipe if need be. the intake pipes will be terminated outside with wire mesh and a dryer type louvers to keep insects out. If any body has any suggestions, or have any other idea, it would be appreciated.
