MULTIPLE UNIT INSTALLATIONS
Proper installation of multiple water heaters assures water ow balance of all units. Without this balance, the full water heating and storage
potential of the system cannot be achieved. Plus, the units with the higher water ow may have a shortened life.
Dimensions shown are for minimum space occupied by the water heaters assemblies.
Space for the venting system and unit servicing must be added.
Manifold Kits for multiple unit installations are not available from the manufacturer.
