DFE means decritive fire/flame effect and ILFE or IDFE means inset Live/decrative flame/fire effect. Basicly DFE is a gas fire that is made to look like a log fire, and a ILFE is the same but is inside the builders opening, so its in the chimley. that's the only really diffence, there is more on the techncal side/the installer side of it all.
Yes, Clorox Green Works products are recognized by the U.S. Environmental Protection Agency (EPA) under the Design for the Environment (DfE) program. This designation indicates that the products meet specific criteria for environmental safety and performance. However, it's important to note that not all Green Works products may carry the DfE label, so checking individual product labels for certification is recommended.

According to my Haynes repair manual , a DPFE sensor monitors upstream ( before ) and downstream ( after ) exhaust backpressure . By calculating the difference between the two pressures , the PCM ( powertrain control module ) determines exactly the EGR flow rate at all driving conditions
