It's not burning correctly because the flames should be blue. Do you have enough fresh air? Do you have a carbon monoxide detector close to the furnace?

Sounds like you have enough air and the co sensor is definitely good.

Someone with more experience will have to help you. Good luck

Orange flame is ok as long as it is not blowing back. The orange is generally dust being burned by the flame. A yellow flame, however, is not good as this indicates incomplete combustion and a problem with the furnace.

Those can be VERY dangerous furnaces. Just condemned a 1993 NUG/one today. They have had LOTS of cracked heat exchangers/popped compression rings which hold the exchanger together. It will eventually trip the flame rollout switch in front of the burners. Best to get it checked by an experienced pro. Have him put a stick type thermometer by the rollout switch. After the fan cuts in the temp will rise over 100 degF to up to 300 degF and eventually trip that switch as the fan is forcing air thru the crack into the burner area and pushing the flame out the front. May take 5 minutes of running B4 the crack opens enough for this to happen. If it stays under 100 deg F it is Okay. Best to be safe than sorry.
