HOT GAS DEFROST PIPING DIAGRAMS . Page 21 of 24. (Diagram one - sample gas system) 5.0 Sizing of gas piping: Full generator power relies on the gas being delivered in the volumes and pressures as given by the manufacturer, which requires the correct pipe sizing. The following can effect gas pipe delivery: 1. Thickness of pipe and overall distance of generator from primary regulator. Ensuring a Successful Gas Meter Set Gas Meter Header has been kept plumb and square Final grade has a minimum clearance of 6” to the bottom of the meter Gas regulator vent maintains 18” minimum height from grade Gas regulator vent meets 18” clearance requirements from windows, doors, other openings into the building Gas regulator vent maintains a minimum of 10’ from any.
