Important Tip
Stiebel Eltron hot water heaters should only be installed or serviced by licensed installers. These are not do-it-yourself appliances.
Please hand this Operation and Installation Manual and hand over to the home or building owner when the installation is complete.
Operating Instructions for the User and the Technician
1. Operation and Service
1.1 Start-up
The boiler (1) and solar storage tank (11), constitute a functional unit (refer Diagram 4 and 5). Hot water is generated throughout the year by the solar collectors.
The entire heater and hot water system must be filled with water and have adaquate air ventilation. Please, refer to the solar collector’s and the boiler’s installation instructions.
2. Maintenance and Cleaning Routine care and maintenance extends the life expectancy and operating safety of the hot water storage unit. The outer casing should be cleaned with a slightly damp cloth and commercially available neutral cleaning agent, this should be done on a regular basis
2.1 Temperature / Pressure Relief Valve The proper function of the T & P relief valve is required to prevent damage to the hot water storage unit. The T & P valve needs to be open during cold-water addition. The water has to flow from the relief line at full stream.
The discharging water can be hot!
2.2 Decalcification
With hard tap water, a deposit of scale will form on the inside of the storage unit. Based on professional experience, it is necessary to decalcify with commercially available solvents at timely intervals. Follow the manufacturers instructions for solvent use. The hot water storage unit needs to be emptied. The inspection cover must be removed and sediments on the tank bottom must be flushed.
2.3 Replacement of the Sacrificial Anode
Depending on the composition of the tap water, an inspection of the sacrificial anode (Pos. 1, Diagram 1) timely intervals is recommended. With heavy wear, an original equipment replacement anode must be installed to protect the inner container from corrosion. An inspection should be performed at least once a year.
3. Failures – Causes – Correction
Failures
Causes
Correction
Inadequate water pressure
Shut-off valve is not completely open. Cold or hot water line is obstructed.
Open Shut-off valve. Clean or exchange pipes. Hot water flow inadequate
Boiler temperature is set too low. Recommended 176 to 185º F. Heat exchanger is calcified.
Set boiler to recommended temperature. Clean heat exchanger.
Hot water storage tank not being heated
Program selection at the heater control is not properly selected.
Select and set program per instructions.
Outlet quantity inadequate
Aerator at the extraction point blocked.
Unscrew aerator and clean. Hot water supply too fast exhausted
Flow rate too high. Recommended 2.6-3.9 gal./min.
Restrict Spigot valve rate.

6. Set-up and Installation
6.1 Set-up
Inspect the packaging for damage and remove packaging at the installation site. Verify presence of six brass thread to sweat fittings.
The installation site must be structurally capable of supporting the weight of the tank when filled. The location has to be above freezing. The water drainage pipe must be freeze proof.
6.2 Connection Refer to Diagram1 and Diagram 2.
6.3 Heater Installation The installation of the hydronic loop is shown in Diagram 4. The circuit must include a Temperature / Pressure Relief Valve, and air-vent, a check valve, and an expansion tank.
6.4 Hot Water Installation
6.4.1 Prior to installation check that the local conditions are compatible with the appliance design, especially that the maximum working excess pressure of 150 PSI (10 bar.) is not exceeded.
6.4.2 A steel or a copper pipe with insulation can be used for the hot water connectors. Copper pipe with insulation is especially suitable due to its low heat loss.
Required combination
Cold water pipeline Hot water pipeline
Copper pipe copper pipe Steel pipe steel or copper pipe Plastic steel or copper pipe
6.4.3 All safety components must be installed into the cold water supply (7,8,9 & 14 Diagram 4). The order of the individual fittings must be in accordance to local regulations.
6.4.4 The pressure regulator has to be set to 150 PSI (10 bar). It can only be installed into the cold water supply. The supply has to be thoroughly inspected prior to installation. Installation of dirt filters or any other narrowing of the supply line to the pressure relief valve is forbidden.
The pressure relief valve (13) has to be easily accessible. Expansion water generated during the heating has to flow visibly to a drain. The drainage pipe must be large enough to accommodate water drainage with a fully opened T & P valve. The drainage pipe must be protected from freezing and must not lead outdoors.
The pressure regulator (14) has to be set so no water drips from the T & P valve.
Heavy dripping of the T & P valve can be caused by dirt in the valve seat or water pressure. Water pressure needs to re regulated below 150 PSI.
6.4.5 Prior to filling all screws must be tight.
6.4.6 Drainage of the hot water tank is via the drain valve (7).
6.4.7 A re-circulator can be attached to a separate socket across the thermometer. Drill the outer casing with a hole saw ∅ 50 where marked and remove insulation from the socket in that area.
For energy conservation, use of a circulator is not recommended.

6.5 Hot water temperature probe
6.5.1 The hot water temperature probe is to be installed into the upper immersions sleeve (Pos. 3 Diagram1).
6.6 Solar Storage Tank – Temperature Probe
The solar storage tank temperature probe to lower immersion sleeve of the hot water storage tank (Pos. 6 Diagram 1).
The temperature probe must be completely inserted into the probe sleeve.
6.7 Connection to the Solar Unit The installation of the solar loop is shown in Diagram 5. The solar loop must include temp/pressure relief, an air-vent, a check valve and an expansion tank. Refer to the separate operation and installation instructions for the solar collector
SOL 25 plus.
Test operation after installation. Start up must follow the approval of the installer (refer operation and use).
6.8 Sacrificial anode (spare part)
If a sacrificial anode is installed into the SBB … plus storage tank, the following must be observed:
Installation – sacrificial anode
• Pull out the red shut-off plug while simultaneously depressing the pressure ring, Diagram 6.
• Push in the open pipe end of the indicator element until dead-stop.
• Attach the sticker “Note Signal Anode” to a highly visible spot on the insulation.
When the storage tank is not operated with a signal display, the red plug must remain in the anode!
Function – Sacrificial indicator
• After consumption of the anode, humidity escapes through the hollow anode core to the signal cartridge and causes a color change there (refer Diagram 7)
• When the cartridge turns red contact the installer so he can check the anode and if needed replace it.
Routine maintenance improves operating safety and life expectancy of the solar hot water storage tank SBB … plus.
