Bought my Harman XXV in April and finally installed it today. AND of course it won't start. I plug it in, put it in auto mode, and the blowers work, but the auger won't feed and the igniter won't fire. The ignitor and feed motor lights don't light up. So i tried it in manual mode. I loaded the burn pot, put a good amount of gel on the pellets, mixed it around, and lit it. It seems every time i close the door the fire goes out shortly there after. I can't seem to get it to stay lit. So maybe i have a draft issue? Would this cause the igniter and feeder not to work? Its a corner installation. The vent setup is Simpson Durevent. The vent sections go appliance adapter, 45 degree, horizontal 1 foot long adjustable , horizontal 1 foot long, thimble, horizontal 1 foot long adjustable, tee with cleanout, vertical 3 foot long, 90 degree, horizontal cap. I also have the integrated simpson duravent outside air kit thimble hooked up using 3" flex pipe. All of the seams are sealed. Would running an extension cord have any ill effect? I thought i read the plastic flat head screw next to the ignitor light may need to be adjusted depending on voltage supply. Also a general question, there is a black high / low switch located on the firewall in the control panel cubby. I see no mention of this switch in the manual. What is it? Any ideas on what to do to troubleshoot this? thanks.
