1. Refer to table and Figures 14 or 15. Pipe exactly as shown. Satisfactory operation of a steam heating system depends on adequate condensate return to boiler to maintain a steady water level. Avoid adding raw make-up water. Where condensate return is not adequate, install low water cut-off and pump control, condensate receiver,and condensate boiler feed pump. Refer to Figure 16 for sizing.

2. Install steam relief valve vertically in“E” tapping.

Relief valve discharge piping must be piped
near floor close to floor drain to eliminate
potential or severe burns. Do not pipe to
any area where freezing could occur. Do
not plug, valve or place any obstruction in
discharge line.	Figure 16 Condensate receiver capacity
