WATER CONNECTIONS
7.1 Water Quality
Water heaters must be installed in water conditions
of 15 gpg hardness or less, with a pH range of 6.5
to 9.5 pH. Values outside of this range may reduce
the life expectancy of the product. Operating the in
water with higher hardness levels will cause heat
exchanger fouling, erosion, or corrosion, leading to
heat exchanger failure or system failure. Failure
of this type will not be warranted. If the water in
use exceeds the conditions recommended, water
softeners or other devices should be installed to
improve water quality.
Pump
NOTES:
1. Locate DHW sensor or remote aquastat well
in lower 1/3 of tank.
3. Thermal expansion tank may be required - check local codes.
Caution:
4. Pump sizing must be based upon water hardness at job site.
5. If the tank does not have a tapping for the cold water supply, the supply may be run
to the pipe between the tank and boiler inlet.

7.2 Suggested Piping Schematics
Figure 13 through Figure 15 show suggested piping
are only meant as guides. All components or piping
required by local code must be installed.
7.3 Piping Requirements
The water piping should be supported by suitable
with this appliance. The hangers used should allow
for expansion and contraction of copper pipe.
Rigid hangers may transmit noise through the
system resulting from piping sliding in the hangers.
We recommend that padding be used when
rigid hangers are installed. Maintain 1" (2.5 cm)
clearance to combustibles for hot water pipes.
