LOCATION AND OPERATION
NOTE: MINIMUM BTU/H REQUIRED TO ACHIEVE FIRST HOUR RATING
LOCATION
Choose a location for your water heater centralized to the piping system. You must also
locate the Super Stor Ultra where it will not be exposed to freezing temperatures.
Additionally, you will need to place the water heater so that the controls, drain, and inlet/out-
lets are easily accessible. This appliance must not be installed outdoors, as it is certified as
an indoor appliance, and must also be kept vertical on a level surface.
OPERATING YOUR SUPER STOR ULTRA
“Boiler high limit should be at least 20° higher than the Super Stor Ultra temperature. Set the
low limit of the boiler control at the minimum setting – this will call the burner on, only to
satisfy the tank control. The differential should be 10° to 15°, if your control is adjustable, be
sure that it is in that range. We recommend a temperature setting of 119°F, or in accordance
with local and state codes for normal operation. You may prefer a setting of either higher or
lower temperature, to satisfy your needs. A mixing valve in connection with a high temper-
ature setting may be used for high demand applications (spas, hot tubs, whirlpools)”
DANGER
This water heater must not be located near flammable liquids such as Gasoline,
Adhesives, Solvents, Paint Thinners, Butane, Liquefied Propane, etc.; as the controls
of this appliance could ignite vapors causing an explosion.
CAUTION
This unit must be placed where leakage from the relief valve, leakage from the related
piping, or leakage from the tank or connections, will not result in damage to the
surrounding areas, or to the lower floors of the building. A water heater should always
be located in an area with a floor drain or installed in a drain pan suitable for water
heaters. Heat Transfer Products Inc. shall not be held liable for any such water damage.

PLUMBING
PLUMBING
It is mandatory that all plumbing is done is accordance with all local and state plumbing
codes, or warranty will be voided. It is also necessary on all mechanical connections, that
you use both thread tape and pipe dope.
NOTE: WHEN FILLING THE SUPER STOR ULTRA, MAKE SURE THAT YOU OPEN THE HOT
WATER TAP TO RELEASE AIR IN THE TANK AND PIPING.
BOILER CONNECTIONS
Use a 1" nominal minimum tube size, wherever you are using zone valves or circulators;
where a 1" zone valve and 1" tube is required.
On the tank, the boiler supply is to be connected to the outlet of the circulator. The inlet of
the circulator is to be connected to the “HOT OUTLET” side of the boiler. Be sure that the
arrow on the circulator is facing toward the flow direction, (See pressure drop sizing for cir-
culator, page 8). On the tank, the boiler return is to be connected to the return side of the
boiler. The return(s) from heating loop(s) should have a flow check or swing check valve
installed before the return pipe from the tank.
In a steam boiler, the tank supply must be connected to the boiler, well below the minimum
water level. A strainer and a drain valve should be installed at the boiler for periodic drain-
ing of scale and sludge. Banging and steam bound traps will occur if the boiler water sup-
plied to heat exchange has steam, or is slightly above the low water cut-out.
It is possible to use live steam in the heat exchanger of the Super Stor Ultra 80 and Super
Stor Ultra 119 only. Consult factory for suggested piping and required components. The
Ultra commercial series Super Stor Ultra 80C and Super Stor Ultra 119C are also included
in this application.
DANGER
Water temperature over 125° F. can cause severe burns instantly,
or death from scalds. Children, disabled, and elderly are at
highest risk of being scalded. See instruction manual before
setting temperature at water heater. Feel water before bathing
or showering! Temperature limiting valves are available.
WARNING
Never use dielectric unions or galvanized steel fittings on any domestic
water connections. Use only copper or brass fittings. Teflon thread
sealant must be used on all connections.
CAUTION
Risk of scald injury increases as you increase water temperature! If draining of the
SuperStor Ultra is necessary, open the T & P valve or a hot water tap, to prevent
vacuum buildup in the tank and piping.

9
PLUMBING AND WIRING
COLD WATER INLET
Use both thread tape and pipe dope and connect an NPT brass tee. On the run, install a
brass drain valve. In the branch, install an NPT male X ¾ “ (minimum) tube adapter. A shut
off valve between city water supply and tank inlet is recommended for ease of service at a
later date. It may be recommended to use a back flow preventer – check your local codes
If a back flow preventer, or a return valve is not used; a thermal expansion tank must be
installed on the cold water supply, between the tank and valve. If the tank is replacing a tan-
kless coil in the boiler, disconnect coil plumbing and use the cold inlet pipe and hot water
outlet pipes for the Super Stor Ultra tank.
DOMESTIC HOT WATER OUTLET CONNECTION
Use both thread tape and pipe dope, and connect an NPT brass tee. In the run of the brass
tee, install an NPT brass T & P valve long element, for hot water storage tanks (Required by
local codes, but not less than the valve certified as meeting the requirements for relief valves
for hot water heaters (ANSI Z212B-1984), by a nationally recognized lab that maintains peri-
odic inspection of production listed equipment. Make sure that the relief valve is sized to the
BTU/Hour capacity and storage capacity of the water heater. The temperature and pressure
relief valve must be plumbed down so discharge can exit only 6” above, or at any distance
below the structural floor; and cannot be in contact with any live electrical parts.
CAUTION
DO NOT PLUG TUBE OUTLET IN TANKLESS COIL.
WARNING
Following installation of the T & P Relief Valve, the valve lever MUST be operated AT
LEAST ONCE A YEAR by the water heater owner to ensure that waterways are clear.
Certain naturally occurring mineral deposits may adhere to the valve, blocking
waterways, rendering it inoperative. When the lever is operated, hot water will
discharge if the waterways are clear. PRECAUTIONS MUST BE TAKEN TO AVOID
PERSONAL INJURY FROM CONTACT WITH HOT WATER AND TO AVOID PROPERTY
DAMAGE. BEFORE operating lever, check to see that a discharge line is connected to
the valve, directing the flow of hot water from the valve to a proper place of disposal. If
no water flows when the lever is operated, replacement of the valve is required. TURN
THE WATER HEATER “OFF” AND CALL A PLUMBER IMMEDIATELY.
This device is designed for emergency safety relief and shall not be used as an
operating control. A relief valve functions, in an emergency, by discharging water.
Therefore, it is essential that a discharge line be piped from the valve in order to carry
the overflow to a safe place of disposal. The discharge line must be same size as the
valve outlet must pitch downward from the valve and terminate at least 6" above a drain
where any discharge will be clearly visible.

10
PLUMBING AND WIRING
(Optional to save additional energy dollars) In the bottom of the tee (branch) vertically down,
install an NPT tube adapter. Then install two sweat street 90° elbows. This acts as a thermal
loop to prevent thermal siphon action of hot water
EXPANSION TANK
A thermal expansion tank may be required in the system designed for potable water use, to
offset the expansion of stored water as the temperature is elevated (only in systems where
there is no return valve, a back flow preventer, a water meter, or anywhere pressure can
build up as the water is heated). See typical expansion tank on following page.
CONTROL
Install control element into well and tighten in place with screws on control body. Thermal
conductive paste is recommended. Once the control is operational, it is very important to
make sure the control is maintaining the desired operating temperature.
WIRING
All wiring is to be done in accordance with all applicable local and state codes. Turn off all
power related to the boiler starting and wiring procedures. It is recommended that a dis-
connect switch be installed between the boiler control and water heater.
CAUTION
REINSPECTION OF T&P RELIEF VALVES: Temperature and Pressure Relief Valves
should be inspected AT LEAST ONCE EVERY THREE YEARS, and replaced, if
necessary, by a licensed plumbing contractor or qualified service technician, to ensure
that the product has not been affected by corrosive water conditions and to ensure that
the valve and discharge line have not been altered or tampered with illegally. Certain
naturally occurring conditions may corrode the valve and its components over time,
rendering the valve inoperative. Such conditions can only be detected if the valve and
its components are physically removed and inspected. Do not attempt to conduct an
inspection on your own. Contact your plumbing contractor for a re-inspection to assure
continuing safety.
DANGER
WARNING: FAILURE TO REINSPECT THIS VALVE AS DIRECTED COULD RESULT IN
UNSAFE TEMPERATURE OR PRESSURE BUILDUP WHICH CAN RESULT IN SERIOUS
INJURY OR DEATH AND/OR SEVERE PROPERTY DAMAGE.

11
PLUMBING AND WIRING
PRESSURE DROP SIZING FOR CIRCULATOR
You must have a flow rate, from chart on page 3, on the boiler circulator for the water; or
the published ratings cannot be achieved. The chart below represents the tube run and the
water heater ONLY, and does not include any flow checks or zone valves. That resistance
must be added to the value found in the chart below.
