Abstract
A method for controlling an efficiency and/or a wet/dry transition area of a condensing furnace heat exchanger section. A temperature can be sensed in an air stream entering the heat exchanger section, to sense an incoming air temperature of the air stream entering the heat exchanger section. A relationship can be established between the incoming air temperature and an air/fuel mixture to be supplied to a burner. The air/fuel mixture can be adjusted to enhance the efficiency and/or to minimize or reduce unwanted condensation within the heat exchanger section.
