Quick question - Proper placement of Webster OSV valve for Roth Tank Install
Swapping out the old oil tank for a Roth with over head, single pipe feed. Am I correct that a Webster OSV is required, and should be placed after regular on/off valve coming off the top of the Roth? There is already a Firomatic Fusible Safety Valve 1. BEFORE the filter and 2. AFTER (right before Tigerloop that the second shipped with) at the burner. My concern is it sounds like the Roth tank wants as little interruptions within the line as possible/and or, should the Webster also be close to the burner (e.g. after line drops down to meet up with the filter/tigerloop).
