The result is high efficiency, a line-safe exhaust, and a cool deck pass-through.Drew Fryehttps://www.blogger.com/profile/06013965677534522281noreply@blogger.comtag:blogger.com,1999:blog-5399150767029697926.post-87385799735806160502013-12-16T11:43:50.396-05:002013-12-16T11:43:50.396-05:00Nice analysis.

Or did you measure the air temp at the burner?<br /><br />bob<br />s/v Eolian<br />SeattleRobert Salnickhttps://www.blogger.com/profile/17236481906016930762noreply@blogger.com
