We built a modular home and have a "fireplace". It is a wood burning fire box, with the steel chimney. We just put an englander pellet stove in the basement, and now want one upstairs. Heres my problem, I know I can vent out of my existing fireplace, but what about the outside air up? I don't want to cut a hole and have it coming out the front of the house, but is there any other way? I don't want an insert. If we sell the home the fireplace would be more appealing. My brother-in-law has 2 pellet stoves and uses no outside air hook up on his quadra-fires. Englander says it has to be done. What should/can I do?
