Optional reservoir piping:
Modern steam boilers are designed to steam for
less time than older, larger boilers. When replacing
an older steam boiler, the system condensate
return time may be longer than the steaming time.
This can cause the following problems:
•
Boilers fitted with an automatic water feed
could overfill.
•
Units fitted with only a low water cutoff would
shut down and cycle while waiting for
condensate to return.
To size and install reservoir piping, see FIGURE 11
and Bulletin AE-8403 (available through your
Weil-McLain distributor or sales office):
1. Pipe boiler as shown on pages 14 through 16.
2. Use 8" diameter reservoir pipe.
3. Locate centerline of reservoir pipe 1" below
