Darren Posted November 23, 2009 Report Share Posted November 23, 2009 I have a question directed to the 'Northern' folks. Appendix C of the 2006 IRC is a diagram of "Exit terminals of Mechanical Draft and Direct venting systems". This clearly shows dimensions to locating the terminations. However, many installation instructions now are including the phase "or 12 inches above the anticipated snow level." Do your towns or states have a set 'anticipated snow level' or is this something new that still needs to be addressed by the ICC? Today I sent a letter to the Director of NJ Codes and Standards requesting some type of clarification, but I'm wondering what you guys are calling out (if anything) when the direct vent is only 12 inches above grade?
