Primary concern would be overheating the furnace fire box. There is a high limit switch that will cycle the burner while the fan continues to run and blow air. If you notice the burner cycling, maybe every two minutes, I do not recommend running the furnace with the restricted air flow. Need the slide out or add some additional unrestricted ducting.
It seem to cycle normally. But thank you for your input.
