Does anyone know the factory settings for the 2005 Englander 25 PDVC pellet stove? Have been reading posts about this and mine are set at 6 for Low Fuel Feed, 9 for Low Burn Air and 1 for Air on Temp. I bought the stove used last month and it is running ok but seems to have a lot of ash and it seems that the Low Burn Air is way high compared to all others I have read. Would a lower setting have any effect on this? Thanks.
