I am regretting buying this heater 2 years ago but stuck with it..Won't get into why I had to spend $100 on a new control board after a year..Problem is the vent is under a house eve, maybe 6 ft up, but the exhaust smell gets trapped and stinks..I refuse to pay $180 for a piece of sheet metal so wondering if anybody has made a vent..It's outside so if it isn't 100% sealed no big deal, just want to redirect the exhaust away and behind the house.
