NOTES
1) For actual sizes and locations of piping and other connections to
the boiler, see appropriate dimensional drawing.

permit the fluids to drain freely by gravity to a convenient floor
drain. The relief valve should be piped vertically to a height 18"
above the floor.
3) All piping and electric connections (service switches, conduit
boxes, etc.) should be 6" away from side panels.
4) Mandatory: primary pump
5) Mandatory: boiler strainer (20 mesh or finer).
6) Recommended: Gas regulator (and is required when supply
pressure is greater than 13" W.C.)
7) All drawings are of typical installations. Local codes and
authorities should be consulted.
