Works for Quadrafire Castile
So far so good. I have a circa 2005 Quadrafire Castile. Symptom was that after initial feed and fire ignites, second stage of auger feed does not begin, and fire goes out. Original Vacuum switch part DFS-221-271 failed in 2019. Got OEM replacement part DFS-221-347. That switch worked for five years, but same problem happened again. This new part has different form factor (round instead of square) and plastic rather than metal, so wasn’t sure if it would work, but got it installed, and unit is working again just in time for colder weather. Red wire on + and orange wire on -. Hope this info helps others troubleshooting their stove.

Worked great!
Arrived early, installed easily (I only used one screw because it's half the size of the OEM vacuum switch), and my CB 1200i pellet stove was back and working again like normal! I used the longer of the two included hoses and it installed very easy. 15 minute job.
