Installing multiple tanks in a battery only for 79 and 120 USG / 300 and 450 ltr capacity
Two tanks, each with 79 USG / 300 ltr content, or up to four tanks , each with 120
USG / 450 ltr content , may be installed side-by-side.
The tank battery is controlled via one DHW tank aquastat making control of individual tanks within the tank battery impossible.
If control of individual tanks within a battery is necessary, two alternatives exist.
Either a 4-tank battery needs to be separated into smaller batteries i.e. two batteries each consisting of two tanks (one DHW tank aquastat controls each battery), or all tanks should be installed individually i.e. individual tank set-up (one
DHW tank aquastat controls each tank).
Y Y
1.
Install aquastat in the boiler water supply of the last tank receiving the boiler water of the tank battery (see illustration).
2.
Install domestic cold and hot water header lines (see illustration).
3.
Install boiler/solar water supply and return header lines (see illustration).
4.
Make final cold and hot water connections.
IMPORTANT
Both the boiler/solar supply/return header and the domestic hot/cold water header must be installed in a reverse return method. This ensures uniform heating of all tanks in the battery. Header sizes for batteries up to four 79 to 120 USG / 300 to
450 ltr tanks are printed on page 8.
5.
Insulate header piping lines.
CAUTION
In commercial installations, we recommend the installation of an additional high limit aquastat in the main discharge pipe of domestic hot water from the tank battery into the system, and to wire this additional high limit aquastat in series with the operating aquastat.

WARNING
The operating aquastat and any secondary high limit aquastat of the tank must be set such that the DHW temperature inside the tank never exceeds 210°F / 99°C.
DANGER
Domestic hot water temperatures over 125°F / 52°C can cause severe burns instantly or death from scalds.
Children, disabled and elderly are at highest risk of being scalded.
Feel water before bathing or showering.
Temperature limiting valves are available and must be used where domestic hot water storage tank temperatures exceed 140°F / 60°C.

The circulation pump is activated by the operating aquastat or by the control system installed. The operating aquastat should be mounted on the tank which receives the boiler water supply last.
Viessmann recommends the installation of an additional high limit aquastat in the main discharge pipe of the DHW system.
This aquastat should be wired in series with the operating aquastat and should be set approximately 9°F / 5°C higher than the operating aquastat.

Proper installation of the T&P valve shall include all of the following:
H Pressure reducing valve
H where required by local jurisdiction
Drinking water filter where required by local jurisdiction
H Back flow preventer
Where backflow preventers are required, a domestic water expansion tank installation is required in the cold water inlet piping before the cold water enters the tank. The back flow device must be installed according to the manufacturer’s installation instructions. Observe local codes and regulations.
- The T&P valve shall be installed in the pipe connection point marked TPV in the Installation Fittings Installation
Instruction Supplement of the tank.
- The discharge line from the T&P valve shall be ¾” / 1.9 cm ∅ and run to a safe place of discharge approximately
1 ft / 30 cm above the floor, close to a floor drain.
- The discharge line must be installed in the shortest distance and pitch downward from the T&P valve and terminate plain.
H Tempering valve
A tempering valve must be field installed where storage tank
(domestic hot water temperature) exceeds local restricted temperatures or 140°F / 60°C. Check code requirements.
WARNING
The discharge line for the T&P valve must be oriented to prevent scalding of attendants.
- Do not route discharge line to the outdoors.
- Do not install any type of valve or an obstruction of any kind between the tank and the T&P valve, or between the T&P valve and the discharge line outlet.
Temperature and pressure relief valve
A temperature and pressure relief valve
(T&P valve) is supplied with the tank.
The heating contractor must install the valve on each tank in a method meeting code requirements.
If local codes require a different relief valve, consult Viessmann
Manufacturing for a substitute valve.
The tank is approved for 150 psig.
Maximum operating pressure is 150 psig.
The T&P valve supplied with the tank is manufactured by Watts Industries
(Model 40XL-8), set to 150 psig for US and Canadian installations. The valve is
ASME pressure steam rated for 998
MBH and CSA temperature steam rated for 200 MBH.
WARNING
The valve test lever must be operated at least once per year by the owner to ensure that waterways are clear. A licensed professional heating contractor shall reinspect the T&P valve at least once every three years.
Failure to inspect can result in unsafe temperature or pressure build-up, which can result in death, serious injury or substantial product/property damage.
Warranty
Our warranty for domestic hot water tanks states that the water heated must be of drinking (potable) water quality and that any water treatment equipment in use must function correctly.
Viessmann accepts no responsibility for damage howsoever caused and reserves the right to withdraw the product warranty if the product has been improperly installed or misapplied by the installer, contractor or final user.
In order to qualify for product warranty, strict adherence to the installation and service manuals must be observed. In the event that Viessmann non-approved components are utilized, Viessmann reserves the right to withdraw all expressed or implied warranties without written notice.
The water to be heated with the
Vitocell must be drinking (potable) water quality. If the tank is used to heat other media, the warranty will be null and void. Damage resulting from excessive pressure or temperature is clearly not the responsibility of
Viessmann.
The amount of chloride and sulfate acceptable to the tank is limited. In areas where high concentrations of chloride and sulfate are present in drinking water, please consult
Viessmann for directions.

Connections
Recirculation Connections
H Pipe domestic hot water supply piping with tank as illustrated. Connections must be accessible for service (use factory supplied adaptors).
Connection sizes are provided in section entitled Orientation and
Dimensions on page 8.
H Install recirculation pump, flow-check valve and recirculation timer (for shut-down during off-hours where feasible) on the recirculation piping side.
H Gravity circulation of the recirculation system is restricted due to the upward-curved domestic hot water discharge piping inside the tank.
H Connect tank battery to existing recirculation piping. Cap off unused recirculation connections of individual tanks.
H Saving Energy
A timer on the recirculation pump reduces the heat loss significantly in commercial applications during times when no or reduced demand for domestic hot water occurs.
