Dear customer,
we thank you that you have bought the VIADRUS OV100 L water heater thus having shown your
confidence in VIADRUS a.s..
For you to get used to a correct way of handling your new product from the beginning please read at
first this manual for its usage (first of all the chapter no. 6 – Heaters operation by users). Please
follow the undermentioned information especially the prescribed annual inspections carried out by
an authorized firm in order to guarantee a long-time and trouble-free heater operation to both your
and our satisfaction.
1. Use and advantages of heater
Indirectly heated accumulation water heater is intended for hot service water preparation in family houses,
cottages, premises, workshops, shops. In case of VIADRUS OV 100 L stationary heater the service water is
heated by heating water by means of a spiral heating wire. In case of an increased HWS (Hot Service
Water) consumption the reservoir heats the water continually and in works like a flow heater.
VIADRUS OV 100 L stationary water heater is preferentially intended for boiler VIADRUS GARDE G 42 and
VIADRUS GARDE G 42 ECO, possibly VIADRUS CLAUDIUS K 2. Its design corresponds to design of
boilers and the boiler electric connection enables a preferential HWS heating.
Accumulation water heater advantages:
1. Uniform heating.
2. Internal surface protected by double layer of enamel
3. Adjustable service water temperature.
4. Economical operation
5. Service water heated quickly.
6. Easy assembly and operation
7. Compared to the flow heaters they enable to draw off the service water simultaneously at several points.

IMPORTANT WARNINGS!
Set the thermostat of the heater to max. 60 °C temperature (note: The regulations in the Czech Republic do
not allow do distribute water of temperatures higher than 60°C).
Once a week set the thermostat of the heater to 65 °C temperature in order to avoid the formation of
legionella (bacillary bacteria originating in water. They die between 60 and 65 °C temperature within several
minutes and at 70 °C temperature they die within several seconds.).

3. Description
3.1 Heater construction
The heater is made of a steel vessel (100 l volume at VIADRUS OV 100 L heater) in which there is installed
the spiral heating wire. The vessel internal surface is enamelled and together with the anode rod it creates an
efficient protection against corrosion and guarantees a long-time service life.
The spiral heating wire is made of a metal pipe and is treated by an enamelled layer. The heater is equipped
with a cover; after unscrewing the cover the vessel can be checked and cleaned.
At VIADRUS OV 100 L heater the cover is screwed to the upper neck of the vessel. In the cover there are
installed the reservoirs for thermostat and thermometer probes and there is screwed the anode protective rod
plus the hot service water input and output. Heating water input and output are at the back of the heater.
The heat loss is reduced markedly by the foam polyurethane insulation.
Fig. no.1 VIADRUS OV 100 L heater assembly (dimensions in mm)
In case of the stationary VIADRUS OV 100 L heater in the lower part of the vessel there is positioned the
discharge hole for a discharge valve. In case that of a demand on the circulation piping it can be connected
through a T-joint connected to the discharge hole.

3.2 Safety and regulation elements
Both reservoirs have their control panels equipped with a thermometer and regulation thermostat on which
the service water required temperature can be set.
In case of a reservoir combined with boiler controlled by an equithermal Honeywell AQ 6000 regulation (or by
other superior automatics which at the same time controls the hot service water heating process), it is
necessary to disqualify the heater from operation and use a thermostat delivered together with automatics.

5.3 Assembly procedure
The heater user is obliged to entrust only a contractual service with assembly and the guarantee and after –
guarantee fault repairs, otherwise the guarantee does not apply to a proper heater function.
1. The heater must be positioned on a required standpoint. We recommend to transfer the heater to
the determined standpoint while it is on a pallet and possibly wrapped in a protective wrapping. If for any
reasons this is not possible please transport the stationary heater without the wrapping by using its lower
support. In this support there are prepared two circular openings intended for putting on the „removal
hooks“, by means of which the heater can be lifted and transferred to the desired place.
Fig. no. 3 Recommended heater connection in heating system with ensured HWS preferential
heating
2. Connect the heater to the heating and water piping system according to the recommended
connection (Fig. no. 3) or the elaborated project documentation. Water for filling the heater must be
pure, clear, colourless, free of impurities, oil and chemically aggressive substances pursuant to
ČSN 75 7111. HWS quality is defined by ČSN 83 0616. Water from heater is considered to be the
service water. Its hardness must correspond to ČSN 07 7401, otherwise it must be softened. Every
independently closable service water heater pursuant to ČSN 06 0830, Article 7.2, must be equipped
with a closure on the cold pressure water inlet, a test cock, a check valve or a clack valve, a safety valve
and a pressure gauge. It is allowed to use a combined fitting consisting of a safety and clack valves. The
safety valve must be connected in a way making sure, that he longitudinal axis of the valve is in the
horizontal position. The valve discharge pipe is to be taken out into the effluent conduit. If the pressure in
inlet piping exceeds 630 kPa (6,3 bar) (applicable also to a transitory condition) then a reduction valve
must be installed in front of the safety valve.
If the HWS preferential heating is carried out by means of three way Honeywell V 4044F valve then
during the assembly it is important to observe the direction of connection in accordance with the
indication on this valve.
B - heating water outlet into the heating system
A - heating water outlet into the heater
AB - heating water inlet from the boiler into the three way valve
3. To carry out the electric interconnection between the heater and the boiler in accordance with the wiring
diagram of the used type of boiler.
4. Insulate the hot water distribution (piping) in order to reduce the thermal losses.
5. All materials used for heater manufacture are recyclable. After the heater unpacking the plastic foil, strip,
wooden pallet and cardboard wrapping must be put into the waste disposal containers intended for this
kind of waste.

5.4 Heaters filling with water procedure
1. Open the combination faucet
2. As soon as the water at the draw-off point starts run out of the hot water valve the filling process is
completed and the combination faucet must be closed.
3. Check the joints tightness.
Warning:
In case that Honeywell V 4044F three way valve is used it is necessary to reset the lever for manual
valve operation from AUTO position into OPEN position. This must be done before the heating
system filling process starts in order to bleed the heater. After the filling process has been completed
reset again manually this lever back from OPEN into AUTO position.
6. Heaters operation by users
1. Set the required hot service water temperature on the heater thermostat. In order to ensure a sufficiently
quick HWS heating we recommend to keep the 15 °C difference between the temperatures set on the
heater and boiler thermostats (like the heater thermostat on 55 °C level and boiler thermostat on 70 °C
level). In order to inhibit the propagation of legionella (bacteria coming up in backwaters at temperatures
below 60 °C) we recommend to set the HWS temperature above 65 °C at least once a week.
2. Keep checking the service water temperature on the thermometer.
