Primary Purpose
Its primary purpose is to maintain a minimum flow rate through the boiler, helping to prevent boiler lockout. This is particularly important in systems serving small areas with short pipe circuits, where minimum flow rates may otherwise not be achieved.
Pre-assembly
The bypass is supplied pre-assembled, with the valve factory set (two turns back from fully closed). It can be installed on either the left or right side of the manifold, positioned between the pump and the manifold.
Installation Guide
To install, remove the end blanks from the manifold bars and connect the bypass assembly to the bar ends. Then refit the end blanks into the open ends of the bypass union.
