General information for all sizes
HFor narrow passageways, remove
upper and lower portion of crating and
carry DHW tank to its installation
location by means of crating boards
mounted on the tank.
HPosition tank carefully and remove
wood crating.
HLeave adequate clearance to the wall
or other objects enabling easy access
to the aquastat (where applicable).
HLocate tank(s) on flooring or
foundation capable of supporting the
weight of the tank(s) filled with
water.
HThe tank does not require a special
foundation and can be placed directly
on the floor. If, for cleanliness
purposes, the tank is to be kept off

Multiple Tank Set-up only for 79 and 120 USG / 300 and 450 ltr capacities
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. Individual control of
tanks within the tank battery is therefore not possible.
If control of individual tanks within a battery is necessary, two alternatives exist.
Either a 4-tank battery can 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).

3. Install boiler water supply and return
header lines (see illustration).
4. Make final cold and hot water
connections.
Both the boiler 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

Installation of a DHW tank temperature sensor or aquastat
1. Carefully pull sensor mounting
hardware out from tank sensor well.
2. Mount sensor on the outside of the
sensor spring-clip (not in the center
groove) so that it is flush with the
front of the sensor spring-clip.
3. Push sensor cabling into groove of
mounting hardware.
4. Carefully tighten plastic screw to
secure sensor cabling in place.
5. Install sensor well and reducing
coupling (included in Connection
Fitting Package). Use approved pipe
sealant.
6. Mount insulation on sensor well.
Where Vitotronic 200 or 300 is utilized
to control DHW production (for
Vitotronic 100, see the following page):
7. Insert DHW tank temperature sensor
(supplied with Vitotronic 200 or 300)
fully and completely into sensor well.
Due to the length of the stainless steel
well (15” / 380 mm), care must be taken
to ensure that the sensing bulb of the
limit is inserted and pushed to the end of
the stainless steel well.

temperature inside the tank never
exceeds 210°F / 99°C.
WARNING
Domestic hot water temperatures
over 125°F / 52°C can cause severe
burns instantly or death from scalds.
Children, disabled and elderly are at

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.

Use hemp and pipe dope on all threaded
stainless steel nipples on tank.
HIsolation valves
HDrain valve
HPressure reducing valve
where required by local jurisdiction
HDrinking water filter
where required by local jurisdiction
HBackflow 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 backflow
device must be installed according to
the manufacturer’s installation
instructions. Observe local codes and
regulations.
HTempering 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.
In situations where a booster pump is
used to maintain DHW pressure,
Viessmann strongly recommends the
installation of an oversized large
expansion tank to ensure longer, less
frequent pump cycles with less severe
pressure gradients. If possible, use
flexible piping before and after booster
pump to isolate system piping from
vibration and shocks.
HTemperature 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, substitute the manufacturer’s
supplied valve. The tank is approved
for 100 psig where a CRN is required.
Maximum operating pressure is 150
psig.
The valve supplied with the tank is
manufactured by Watts Industries
(Model 40XL-8) set to 100 psig for
Canadian installations and set to 150
psig for US installations (where
applicable). The valve is ASME
pressure steam rated for 998 MBH
and CSA temperature steam rated for
200 MBH. It is tested under ANSI
Z21.22 code for Relief Valves and
Automatic Gas Shut-off Devices for
Hot Water Supply Systems. The relief
temperature is set at 210°F / 99°C.
The valve has a male threaded inlet
and female threaded outlet, both ¾”
sizes.
Proper installation of the T&P valve
shall include all of the following:
- The T&P valve shall be installed in the
pipe connection point marked TPV in
the tank instruction manual.
- 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 as short
as possible and pitch downward from
the T&P valve and terminate plain.
-Donot route discharge line to the
outdoors.
-Donot 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.
5285 545 v1.1
IMPORTANT
IMPORTANT
The discharge line for the T&P valve
must be oriented to prevent scalding
of attendants.
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.
