Additional Information:
 If the boiler is to be installed in a system that utilizes zone
circulators and not zone valves a low loss header plumbing kit is
required to be installed.
 If the pressure drop in the loop/system is greater than the available
head pressure from the boiler circulator a Low Loss Header
Plumbing kit part number: 804000061 must be used.
 If the boiler is installed in a system with zone valves and the con-
stant recirculation function is activated then a differential pressure
bypass valve or a low loss header plumbing kit is required to be
installed.
