A thread in the "Hearth" forum got me thinking. If the power goes out, or even flickers, what happens to the pellet stove? Will it re-ignite on its own when the power comes back on? What about the exhaust? Does the house fill with smoke? My vent goes straight up throught the roof for about 20 - 25', and about 8 -10' of that is inside. Will I get enough natural draft from this to clear away any smoke during a power outage? Thanks.
