Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue

Sounds like the heat exchanger may be dirty and/or the blower may be weak/failing. The first thing I would do is remove the blower and vacuum out the heat exchanger. I'd also remove and clean the burners. If that doesn't work you you may need a new blower but to confirm this really need to put a manometer on the draft to check it. Here is a copy of the manual for your unit. Refer to the parts diagram and the blower replacement directions on page 6 for insight into how to approach this.
