Howdy, I have Traeger furnace I'm trying to get to heat my basement. Everything seems to be functioning fine, burning fuel well, heat exchange tubes heat up good, but when the blower comes on it's sucking cold air from the basement and blowing it over the tubes and, after running all day, it hasn't heated up the basement at all. It doesn't seem like it will ever blow out enough hot air with all the cold air being sucked up from the basement. It claims it can be used as a shop furnace but again, while sucking so much cold air from the room and blowing it over the heat tubes it seems like it won't ever catch up and be able to warm up the room. Please don't judge my piping too much, I'll get a better support system in place when I can actually get this thing to work.
