Water connections

WARNING:
B Do not install a non-return check valve
within 10 feet of the inlet.
WARNING:
B Do not apply heat or solder to
connections or pipe if they are already
connected to the unit.
NOTICE: Disclaimer
B In the Commonwealth of Massachusetts
a pressure relief valve shall be installed
on the cold water side by a licensed
plumber. (MGL 142 Section 19, Approval
number P1-09-25).
B The heater must be connected directly to the main
cold water supply and not to pre-heated water. (The
inlet water temperature must not be greater than
86 °F).
B The heater must be installed with shutoff valves on
both the inlet and outlet connections.
B It is recommended that you use ¾ inch or ½ inch
copper or high-pressure flex connections.
B Do not use plastic piping within 3 feet on either side
of heater.
B Use Teflon tape for sealing pipe threads. Do NOT use
pipe dope.
B Remember to keep the hot water pipe runs as short
as possible.
After the heater has been plumbed, and before you
wire it, flush it with water to remove any debris or
loose particles. Heater must be full of water and air
purged before power is turned on. Failure to do so
may result in damage to the product that is not
covered by warranty.
B After flushing and filling the heater with water, (with
power off) disconnect the inlet connection and
inspect the filter screen for any debris that may have
been flushed through the system.
The inlet and outlet connections are clearly
marked on the heater. They each have a
¾ inch NPT connector.
B Check the pressure of the main water supply. To
operate correctly, the heater needs the running
pressures mentioned in Tab. 5.
