View Full Version : Soot in heat exchanger
12-22-2006, 03:19 AM
I recently started having problems with the Intertherm furnace in my five year old manufactured home. The main burner would come on for a short length of time and blow out, along with the pilot. To make a long story short, it was found that the heat exchanger was plugged with soot from overfiring. This had been slowly building up for a long time, and ultimately was the result of the original installer putting in the wrong orfice during a natural gas-to-propane conversion. The technician is recommending replacing the furnace, as he claims the heat exchanger cannot easily be cleaned. Does this make sense?
If I do decide to replace the furnace, I am considering replacing it with a more efficient condensing furnace. Are these furnaces readily available for manufactured homes?

Well replacing the furnace is one option or replacing the heat exchanger.Replacing the heat exchanger is a pain it the butt.What happened to to installing contractor?I feel bad for you but I hope the unit is shut down.
Don't let anyone talk you into having the thing cleaned because the heatexchanger my be cracked.

Intertherm makes a condensing furnce that is approved for installation in manufactured homes. So does Bryant.

I would not stop at the heat exchanger, I Would also check the flue piping. When a system starts producing soot, it will travel all the way up the flue, depending on how long it's gone unnoticed. good luck

Just because the furnace sooted up does not mean it is done for. Have a reputable hvac contracator check it out befor you replace anything.
