Warranty
Proper function is only guaranteed providing these
instructions are followed and the boiler is regularly
maintained by a licensed specialist. (Maintenance contract).
The rectification of faults and damage as a result of
contaminated operating materials (gas, water, combustion
air), unsuitable chemical additives and an inadmissibly high
lime content of the heating water, improper handling, faulty
installation, unauthorised modifications and damage due to
the use of force do not fall under our guarantee obligations,
this also applies to corrosion due to halogen compounds,
e.g. from spray cans, paints, adhesives, halogenated fluids,
solvents and cleanings agents.

Installation
Installation position
Where limited space is available, the Uno-3 can be
transported standing on the door. Hex nuts are mounted
behind the door as supports for this purpose. After
transport, they can simply be screwed back to the bracket.
Release and screw back 6 transport counter
nuts (1, Figure 01) before commissioning.

2.2
Setting up, levelling
A special foundation plate for the boiler is not an essential,
but it is recommended.
Space requirement
For mounting the thermal insulation and sheet metal
cladding:
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,
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.
There must be enough space to swing open the
boiler door, incl. the burner.
Figure 01
Levelling
Using a spirit level, align the upper edge of the boiler water
jacket (longitudinal axis of the boiler) until it is precisely
horizontal or sloping very slightly upwards towards the
rear by inserting the plinth rails correspondingly, to allow
the boiler to vent properly.
Before fitting the burner, first fit the double door
(8a, Figure 05) (door casing).

3.1
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
(thermolytic 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.
3.1.1 The Uno-3 (320, 360) complies with the
following directives + standards

4.1
Installation
Boiler installation 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
regulations for the individual Bundesländer are to be
complied with.
Make sure there is an adequate supply of fresh air to
the boiler room,
to ensure that the combustion air supply necessary for
all the firing systems operated there can flow in without
hindrance and that no oxygen deficiency occurs for the
operating personnel.
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 additionally stipulates a flue
air aperture. This must have a minimum cross section of
180 cm2 up to a rated heat output of 100 kW. For every
further kW, the cross-section must be increased by 1 cm2.
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
Existing flue gas systems may require upgrading
or adjustment of the flue duct cross-section 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) the type (nature) of the chimney (thermal insulation,
interior surface roughness, sealing etc.).
b) the connection of the boiler to the chimney according
to specification.
c) the correct chimney cross section dimensioning.
ref. a)
Chimneys according to EN 13384, part 2, execution
types I and II are appropriate for modern firing systems
(advice from the chimney specialist is necessary).
to 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°.
The entry location of the flue gas pipe must be carefully
sealed.
The introduction of the flue gas pipe into the chimney (A)
must be executed so that no condensate water can flow
from the chimney into the flue gas pipe and the boiler
(Figure 09).
A
Flue connection and dimensioning
To guarantee economic and fault-free operation, boiler
and chimney must be mutually adapted to create
a functional unit.
Moisture-resistant and acid-proof flue gas systems
must be used in new installations.
4 205 120 / 02
Figure 09
Where possible, avoid 90° bends in the flue gas system!
Flue gas pipes longer than 1 m are to be insulated.
17
INSTALLATION
Normally only one heat producer may be
connected to the chimney!
Flue gas pipes longer than 1 m are to 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.

Dimensioning the chimney cross section. The cross
sections are to be calculated for boilers without delivery
pressure requirement according to 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, take note of SIA Recommendation 384/4!
In Austria, calculation is performed as prescribed by
ÖNorm M 7515.

4.3
Installing the burner
• Depending on the size of the burner flange, an
intermediate flange may be required to attach the burner.
• To allow the burner to be swung out 90° to the left
or right, the connections must be flexible and routed to
the burner in sufficiently large loops.
• The cavity between burner pipe and boiler flange must
be insulated with the fireproof fibre provided.
• In systems with ThermoCondensor, the burner
must additionally absorb the resistance of the
ThermoCondensor and the flue.

COMMISSIONING
5.
5.1
Commissioning
• Parts of the boiler which have contact with water are
made of ferrous materials.
Water quality
• 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.
Heating Water
The European Standard EN 14868 and the
directive VDI 2035 must be observed.
• The pH value of the heating water should lie between
8.3 and 9.5 after 6-12 weeks of heating operation.
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!
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.
