Table 5
Condensate receiver capacity
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 13 and Bulletin AE-8403
(available through your Weil-McLain distributor or sales office):
1. Pipe boiler as shown on page 18 through page 20.
2. Use 8" diameter reservoir pipe.
3. Locate centerline of reservoir pipe 1" below 26
