MULTIPLE WATER HEATERS WITH SINGLE VESSEL

When multiple EcoKnight™ water heaters are installed as shown below one water heater is designated as the leader water heater.
The leader will decide how many member water heaters to activate and at what firing rate depending upon information received from

water heaters should be piped on a reverse return arrangement with the pipe header being sized as shown in Section 12.6
