Installation
Water Hammer
Dishwashers, clothes washers and fast-closing pos-
itive shut-off valves incorporated in the system all
contribute to creating water shock. Install a water
hammer arrester to prevent damage to pipes and
appliances. See device manufacturer’s instructions
for application and installation.
Water hammering within the domestic pip-
ing system can cause premature failure of
the inner tank of the water heater. This type
of failure is NOT covered under warranty.
Vacuum Breaker
Installing a vacuum breaker on the domestic cold
water outlet will prevent damage to the inner tank
if a negative pressure is developed in the domestic
supply line. See manufacturer’s instructions for
application and installation of the vacuum breaker.
General Piping

See pages 11 through 14 for:
- Boiler water piping
- Multiple water heater domestic and boiler
piping.
•
See Chart 1 for domestic and boiler piping
connections.
•
All plumbing must meet or exceed all local,
state and national plumbing codes.
•
Use pipe dope or tape suitable for potable
water systems.
•
Use isolation valves to isolate system components.
Domestic Piping
•
Union on domestic hot water outlet should be
piped at a higher elevation than domestic water
drain valve. This will make draining the water
heater easier.
