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.
