Hi all looking for help my original post back in 2014 iwas looking at wood oil combo. Bit the bullet and bought ge200 instead. I''ve had numerous problems with it most recent one appears like i'm not getting air in the burn box. Vent at front is fully open yet fire smothers itself out. Chimney is clean, cleaning tubes are clear. I have no idea what else to look for. Any suggestions would be greatly appreciated.
