EMX, EMXO and EMXGO SERIES WATER BOILERS 2. Oil supply and return lines must be installed below frost level. Below-floor-level runs are preferred inside the building. Avoid overhead runs, which can cause excess lift for the oil pump. Return lines must be as large as the supply lines with no shutoff valves in the line. If a shutoff valve is installed in existing return line piping, remove or open and disable it to prevent accidental closure.
