MANIFOLD KITS
Precision cut type “L” all copper manifold kits assure 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.
CAUTION: IF THE PLUMBING REQUIRES
THE USE OF PIPES WITH DISSIMILAR
MATERIAL (FOR EXAMPLE, STEEL AND
COPPER), USE DIELECTRIC UNIONS TO
PREVENT AN ELECTRO-GALVANIC ACTION
BETWEEN THE PIPING COMPONENTS
WITH DISSIMILAR MATERIALS.
