Question

A customer calls reporting a smell of smoke when the fur-nace starts up. This customer does not have the furnace serviced each year. The technician goes to the furnace in the basement, followed by the customer. The technician turns the system switch off and goes back upstairs and sets the thermostat 5°F above the room temperature so the furnace can be started from the basement. When the technician gets back to the basement, he starts the furnace and observes a puff of smoke. The technician inserts a draft gauge in the burner door port; the draft is 10.01 in. WC positive pressure. What is the likely problem and the recommended solution?
