I am babysitting my parents house for the first time since they installed a pellet furnace to the existing furnace. I have had no problems until this evening/morning. It has been very cold here in Sconny and the furnace has had trouble keeping up. It was suggested that I turn the indicator to Service and run the temp from the furnace, I have the feed adjuster set to 5 and the temp set to 6. There seems to be a hell of a burn going on but nothing is being transferred to the house and the blower is on. I have read the manual a dozen times and it is really vague when it comes to troubleshooting. Any suggestions ? Is this a rookie mistake? Thanks
