I have a Heil Ultimate III Gas furnace installed by the home builders about 7yrs ago, I need the user manual to look up some information, can anyone provide me with a copy?
OR, can help me out with this. I currently have the fan set to "ON" on the thermostat. I noticed that when the furnace's burners turn on the main fan turns off for 2 seconds and turns back right on, is this normal operation? Does not this reduce/hurt the fan?
