2.2
Setting up, levelling
A special foundation plate for the boiler is not an
essential, but it is recommended.
Space requirement
for fitting the heat insulation and casing panelling:
at least 40 cm each on the left and right side of
the boiler.
If the space between the boiler and the wall is less
than 50 cm, all heat insulation and casing must be
fitted before the boiler can be pushed into its final
position.
Do not connect lines until the heat insulation
and casing have been fitted to the boiler!
There must always be enough space
between the back of the boiler and the
wall to allow easy access to the cleaning aperture in the flue gas collector.

Technical information
Description of the boiler
The Uno-3 is a threepass boiler. At the end of the
circular cylindrical combustion chamber, the flame
gases flow through several cylindrical tubes arranged
above the combustion chamber and towards the front
to the turning chamber, from where they flow through
rectangular ducts (thermolyt. heating surface) towards
the rear and reach the flue gas collector.
The flue gas temperatures can be varied within a
specific range through the installation of various regulator combinations.

4.1
Boiler room requirements
Regarding the building specifications for boiler rooms
and their supply and extract air handling, the current
building supervisory office regulations specific to the
state or country are to be observed. In Germany, the
firing ordinances of the individual federal states must
be observed.
Ensure that there is an adequate supply of fresh
air to the boiler room,
so that the amount of combustion air required for
operation of all the burners installed there can be
continuously replenished without hindrance and that,
for the protection of operating personnel, there is no
shortage of oxygen.
Binding values for the size of supply air openings are
not generally specified in the relevant regulations; it is
merely required that no partial vacuum in excess of 3
N/m2 occurs. An opening or line leading into the open
air of at least 150 cm2. For every kW in excess of 50
kW, a further 2 cm2 must be calculated. In rectangular
openings, the ratio of the sides should not exceed
1.5:1; if a grid is fitted, an appropriate allowance must
be added so that the free cross-section area reaches
the amount given above.
In Austria, ÖNorm H 5171 also requires an extract air
opening. Up to a nominal heat output of 100 kW, this
opening must have a minimum cross-section of 180
cm2. For every further kW, the cross-section must be
increased by 1 cm2.
Installation
Existing flue gas systems may require upgrading or adjustment of the flue duct crosssection as indicated by a chimney engineer.
The correct functioning of the flue duct, i.e. the generation of the required delivery pressure depends on:
a) type (materials and characteristics) of the flue duct
(thermal insulation, internal surface roughness,
leak-tightness etc.)
b)connection of the boiler to the flue gas system
according to applicable regulations and standards
c) correct dimensioning of the flue duct cross-section.
re: a)
Flue gas systems in accordance with EN 13384, Part
2, types I and II, conform to state-of-the-art combustion
systems (a chimney engineer must be consulted).
re: b)
The flue gas pipe connecting the boiler to the flue gas
system must be as short as possible and placed at
an angle of 30-45°.
Carefully seal the flue gas pipe against the flue gas
system.
The insertion of the flue gas pipe into the flue gas
system (a) must be carried out in such a way that no
condensation water can flow from the flue gas system
into the flue gas pipe and into the boiler. (Fig. 10)
The flue gas system must be watertight, acid-proof and approved for the
corresponding flue gas temperatures.
As a general rule, only one heat generator
should be connected to the chimney! When
using two heat generators, the corresponding
regulations must be observed.
4.2
Connection of the flue gas system
and flue duct dimensions
Boiler and flue gas system must be mutually compatible and operate as a single functional unit in order
to guarantee trouble-free and economical operation.
a
Fig. 10
Where possible, avoid 90° bends in the flue gas system!
Flue gas pipes over 1 m in length must be insulated.
Moisture-resistant and acid-proof flue gas systems must be used in new installations.
15
Installation
4 205 118 / 01
As a general rule, only one heat generator may be connected to the chimney!
Flue gas pipes over 1m in length must be insulated.
If an adapter (reducer) from the flue gas outlet of the
boiler to the entry point into the flue gas system is
required, it must take the form of a slim cone.

zum
Schornstein
re: c)
Dimensioning of the flue duct cross-section. The
cross-sections must be calculated for boilers without delivery pressure requirement in accordance
with EN 13384. (Please also observe DIN 18160,
Part 1 "Domestic chimneys"). Take into consideration location-specific factors (hillside location of the
building, chimney position, slope of the roof, chimney
stack exit shape, etc.)!
In Switzerland, SIA recommendation 384/4 must be
observed!
In Austria, calculation is performed as prescribed by
ÖNorm M 7515.

Setting the temperature regulators
- without heating regulator:
Set the boiler temperature in accordance with the
outside temperature.
- with heating regulator:
The heating regulator automatically sets the correct
boiler temperature. The boiler temperature varies
between the minimum and maximum boiler temperatures entered.
If a calorifier is connected, the priority circuit
disables the boiler temperature regulator until
the temperature is reached. The boiler temperature can rise to approx. 85 °C.
4.9
Safety valves
The heating system and hot water supply must each
be protected with one safety valve against impermissibly high pressures. The discharge capacity of
the heating system safety valve must correspond
to the boiler’s maximum nominal heat output. The
valve is installed in the safety flow. In Germany, only
safety valves with the code letter "H" in the approval
mark may be connected, and they must always be
connected at the boiler safety flow. Water shortage
protection in accordance with EN 12828 Part 2 Section
9 is mandatory.
4.10 Charging pump (boiler with free-standing calorifier)
Speed of rotation and output regulation must correspond to the requirements of the free-standing calorifier.
Setting carried out by the heating installation engineer.

5.Commissioning
• Parts of the boiler which have contact with water
are made of ferrous materials.
Heating Water
• On account of the danger of stress cracking corrosion the chloride, nitrate and sulfate contents of the
heating water must not exceed 200 mg/l in total.
5.1
Water quality
The European Standard EN 14868 and
the directive VDI 2035 must be observed.
In particular, attention must be paid to the following
stipulations:
• Hoval boilers and calorifiers are designed for heating plants without significant oxygen intake (plant
type I according to EN 14868).
• Plants with
- continuous oxygen intake (e.g. underfloor heating systems without diffusion proof plastic piping) or
- intermittent oxygen intake (e.g. where frequent
refilling is necessary)
must be equipped with separate circuits.
• Treated filling and replacement water must be
tested at least 1x yearly. According to the inhibitor
manufacturer‘s instructions, more frequent testing
may be necessary.
• A refilling is not necessary if the quality of the heating water in existing installations (e.g. exchange of
boiler) conforms to VDI 2035.
The Directive VDI 2035 applies equally to the replacement water.
• New and if applicable existing installations need
to be adequately cleaned and flushed befor being
filled. The boiler may only be filled after the heating
system has been flushed!
• The pH value of the heating water should lie between 8.3 and 9.5 after 6-12 weeks of heating operation.
Filling and replacement water
• For a plant using Hoval boilers untreated drinking
water is generally best suited as heating medium,
i.e. as filling and replacement water. However, as
not all drinking water is suitable for use as as filling
and replacement water the water quality must fulfil the standard set in VDI 2035. Should the mains
water available not be suited for use then it must
be desalinated and/or be treated with inhibitors.
The stipulations of EN 14868 must be observed.
• In order to maintain a high level of boiler efficiency
and to avoid overheating of the heating surfaces
the values given in the table should not be exceeded (dependent on boiler performance ratings - for
multi-boiler plants rating of smallest boiler applies
- and on the water content of the plant).
• The total amount of filling and replacement water
which is used throughout the total service life of
the boiler must not exceed three times the water
capacity of the plant.
