MANIFOLD KITS
Precision cut type “L” all copper State manifold kits assure water
flow 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 flow may have a shortened
life. Unions shown in piping diagrams are not included in the
manifold kits.
Dimensions shown are for minimum space occupied by the
water heaters assemblies.
Space for the barometric draft control assemblies, combustion
clearances and servicing must be added.
WARNING
FAILURE TO PROPERLY MANIFOLD MULTIPLE WATER
HEATERS AND PROVIDE ADEQUATE STORAGE CAPACITY IN
ACCORDANCE WITH PROPER SIZING TECHNIQUES CAN RESULT
IN IMPROPER OPERATION AND POSSIBLE FIRE RESULTING IN
PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
HEATERS SHOULD BE MANIFOLDED IN PARALLEL FOR
UNIFORM HYDRONIC LOADING PER THE DIAGRAMS SHOWN
IN THIS MANUAL.
