From the Service Manual - SOOT (caused by lazy yellow flame)
LAZY FLAME (yellow)
High gas pressure - Set gas pressure to a minimum of 11” W.C. with all appliances running replace regulator, if not obtainable. Also, check main burner orifice, it must comply with furnace’s specifications
Burner out of adjustment Adjust burner according to furnace specification
Combustion wheel installed backwards or loose (warranty covered only when improperly installed at the factory)Reposition wheel and tighten
Air leakage at gaskets Replace gaskets
Low voltage Correct power supply
