Installation Superstor Ultra Indirect Fired Water Heaters Start-Up Maintenance Parts Warranty For Residential and Commercial Use SSU Models The surfaces of these products contacted by potable (consumable) water contain less than 0.25% lead by weight as required by the Safe Drinking Water Act, Section 1417. This manual must only be used by a qualified installer / service technician. Read all instructions in this manual before installing. Perform steps in the given order.
The following defined terms are used throughout this manual to bring attention to the presence of hazards of various risk levels or to important product information. DANGER indicates an imminently hazardous situation which, if not avoided, will result in serious personal injury or death. WARNING indicates a potentially hazardous situation which, if not avoided, could result in personal injury or death.
C. Freeze Protection NOTE: If the heater is exposed to the following, do not operate until all corrective steps have been made by a qualified serviceman: 1. Fire 2. Damage 3. Water Failure to follow this information could result in property damage, severe personal injury, or death. High heat sources (sources generating heat 100oF / 37oC or greater, such as stove pipes, space heaters, etc.) may damage plastic components of the water heater as well as plastic vent pipe materials.
A. Locating the Water Heater High heat sources (generating heat 100oF / 37oC or greater, such as stove pipes, space heaters, etc.) may damage plastic components of the water heater as well as plastic vent pipe materials. Such damages ARE NOT covered by warranty. It is recommended to keep a minimum clearance of 8” from high heat sources.

Performance and Sizing Guidelines NOTE: The table below describes the minimum BTU/H required to achieve the listed first hour rating.
C. Reduced Boiler Input Sizing Guide NOTE: IT IS NOT RECOMMENDED TO REDUCE BOILER INPUT WHEN USING DOUBLE WALL TANKS.
D. Water Chemistry Requirements in the water. • If using softened water to fill the appliance, it is still possible to have high TDS. This water can be corrosive. Consult local water treatment companies for other treatment solutions to reduce this affect. *NOTE: To promote appliance service life, it is strongly recommended to follow the maintenance procedures in this manual. Chemical imbalance of the water supply may affect efficiency and cause severe damage to the appliance and associated equipment.
Use both thread tape and pipe dope to connect an NPT brass tee. On the run, install a brass drain valve. In the branch, install an NPT male X 3/4” (minimum) pipe adapter. A shut-off valve between the city water supply and tank inlet is recommended for ease of service. It may be recommended to use a back flow preventer - check local codes. If a back flow preventer or a no return valve is used, a thermal expansion tank must be installed on the cold water supply between the tank and valve.

Part 4 - Heater Control and Wiring A. Control Install control element into the control well and tighten into place with screws on the control body. Thermal conductive paste is recommended. Once the control is operational, it is important to make sure the control is maintaining the desired operating temperature. CAUTION NOTE: DO NOT attempt to remove the control well! The control well is welded to the water heater.

Part 5 - Start-Up and Operation 1. Fill the water heater by opening the cold water shut-off Risk of scald injury increases as you increase water temperature. valve. Purge air from the system by opening a hot water outlet at a fixture in a kitchen or bathroom. When water flows freely from the outlet, the system is purged. When filling the water heater, open a hot water tap to release air in the tank and piping to ensure proper water heater operation.
Part 6 - Maintenance and Troubleshooting Periodic maintenance should be performed by a qualified service technician to ensure all equipment is operating safely and efficiently. The owner should make necessary arrangements with a qualified heating contractor for periodic maintenance of the heater. Installer must also inform the owner that the lack of proper water heater care and maintenance may result in hazardous conditions.
