Installation
The manufacturer’s warranty does not cover
any damage or defect caused by installation
or attachment or use of any special
attachment other than those authorized by
the manufacturer into, onto, or in
conjunction with the water heater. The use
of such unauthorized devices may shorten
the life of the water heater and may endanger
life and property. The manufacturer
disclaims any responsibility for such loss or
injury resulting from the use of such
unauthorized devices
INSPECT SHIPMENT
Inspect the water heater for possible shipping
damage. The manufacturer’s responsibility
ceases upon delivery of goods to the carrier in
good condition. Consignee must file any claims
for damage, shortage in shipments, or non-
delivery immediately against carrier.
DOMESTIC WATER CONNECTIONS
This water heater may be connected individually,
in multiples with others, or with an external hot
water storage tank. If two TURBOMAX
®
or more
are installed, the piping method to be used to
connect the TURBOMAX
®
in parallel should be
“reverse-return piping”, so domestic water flow
rate through each TURBOMAX
®
is equal.
The HOT WATER OUTLET and the COLD
WATER INLET connections are clearly marked.
Inlet water connections (COLD WATER INLET)
are to be made to the copper pipe (sweat
connection) at the bottom of the heater. Outlet
water connections (HOT WATER OUTLET) are
to be made to the copper pipe (sweat
connection) at the top of the heater.
The installation of copper unions or copper alloy
unions is recommended on the HOT and COLD
water lines, so that the water heater may be
easily disconnected for servicing if necessary.
Dielectric unions are required for protection of
the water heater if dissimilar pipe material like
galvanized pipe is used.
Install shutoff (ball) valves for servicing
convenience.
Use only clean copper or approved plastic pipe
for water connections. Local codes or
regulations shall govern the exact type of
material to be used.
To minimize heat loss during non-draw periods,
a heat trap formed from piping can be used.
Insulate all pipes containing hot water, especially
in unheated areas.
Cap or plug unused connections. If the water
heater is replacing a tankless coil in the boiler,
do not cap tube outlets in the tankless coil after
disconnecting from plumbing.
Thermometer(s) should be installed to indicate
the temperature of the water at or near the outlet
of the water heater and storage tank(s), if
provided.
EXPANSION TANK FOR POTABLE
WATER
Determine if there is a check valve, a back flow
preventer, a pressure-reducing valve, a water
meter or a water softener in the cold water
supply line.
A check valve creates a closed system and
prevents the water, as it is being heated, from
expanding back into the cold water supply line.
Pressure can build up within the water heater,
causing the relief valve to operate during a
heating cycle. This excessive operation can
cause premature failure of the relief valve and
possibly of the water heater itself.
Replacing the relief valve will not correct the
problem. One method of preventing pressure
build-up is to install an expansion tank for
potable water in the cold water supply line
between the heater and check valve. Contact
your installing contractor, water supplier, local
plumbing inspector or plumbing supply house for
assistance.
RECIRCULATION LINE (IF APPLICABLE)
If a recirculation line is installed, the return
connection should be made to a tee close to the
inlet connection on the water heater. A check
valve should always be installed in the
recirculation line to prevent cold water from
entering.
