Direct answer
Pellet vent is a defined term in the International Residential Code (IRC) 2009, in Definitions. The code's own words are: “A vent listed and labeled for use with a listed pellet fuel-burning appliance.” No other I-Code in this corpus defines it, so the IRC 2009 definition is the one to work from. The term is used in 6 chapters of this corpus, most often in Chimneys and Vents (IMC 2009), Masonry (IBC 2009), Definitions (IMC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted. Record the jurisdiction, the adopted edition, the application date and any local amendment that rewrites the definition before you use it on a live project, because a term redefined by amendment changes every requirement that depends on it.
