Circulation Pump 

A calculation for proper  pump selection must be performed for all installations.  The pump(s) 

should not  be  operated at maximum working  pressures above  30 psi or  maximum working 

temperatures above 200°F and within limits advised by the manufacturer.  The pump must not be 

operated unless the system has been flushed, bled of all air and completely filled with water. 

 

Recommended locations for the circulator, expansion tank, relief valve and other trim are 

shown in Figures 1 - 7. 

Figure 1: A typical installation with no domestic hot water and no by-pass 

loop installed.
