EASY-LINK SYSTEM
The water heater can be connected with other heaters of the same model with communication
cables to work as a multiple manifold system.
 The Easy-Link system can connect up to 4 units.
 A communication cable (gray color) comes with each unit. The cables use 18 gage wire
and can be up to 250ft. long all together.
You can manifold from 2 units to 4 units without a multi-system controller. A 4-unit system has
full automatic modulation between 24,000 BTU/h and 960,000 BTU/h.
 The Easy-Link system is limited to 4 units. If you connect more than 4 units,
the first 4 units will work as part of the Easy-Link system, but the other
additional units will only work as individual units.
 The water heater cannot be linked with other different models in the
Easy-Link system.
