How Do I Adjust the Pilot on the Burnham P204 Furnace?

The Burnham P204 is a gas furnace designed for residential use. The pilot light inside the unit burns continuously to activate the furnace when the temperature in the building falls below a preset level. Adjusting the pilot light helps the furnace burn efficiently and makes it less likely for the pilot to shut off, resulting in a cold house when the furnace stops working. A small adjustment screw on the side of the pilot light alters the air-gas mixture so the flame is the proper size and color. Does this Spark an idea?
