Both my neighbor and Bro in law have the same regency i2700. Both had issues with snapped bolt heads while removing the bypass access plate at the back of the firebox. We did get one of the plates off, moved the bypass, and could not use the sooteater because the angle was too sharp for the flex rods. I have a napolean and removing the air rods and baffle to clean is an overall breeze. What is the trick for these regencys? Just trying to clean these things before we even worry about removing sheared off bolt heads upside down in a fire box (sigh)
