Important notes
1.4Guarantee
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.

2.Installation
2.1
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.
Boiler door pivotable to the left
It is possible to change the attachment of the boiler
door so that it opens towards the left. This can be of
advantage when installing the boiler in a corner.
Proceed as follows:
Close the boiler door and lock it in position
before changing the attachment of the door.
2
1
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.
Do not overtighten boiler door screws.
Fig. 2
1. Pull up the semicircular rivet (1).
2. Change over the swivel arm (2).
3. Insert the semicircular rivet (1) on the other side.
4. Fit the burner plug and the fire protection switch
(if fitted, Austrian version) on the other side
(see point 2.3, item 9 and point 4.5.1).
The cable must not touch any hot
parts!
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 (Pos. 8b, Figure 7) (door casing).

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.

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 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.
4 205 116 / 02
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)establishing the correct flue duct cross-section
dimension.
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. (Fig. 10)
The flue gas system must be watertight, acidproof 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
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.

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.)!

Fitting 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.
4.3.1 Sound insulation
- Gas pipes must be mounted in such a way that no
vibrations are transferred to the building.
- The burner can be equipped with a sound-absorbing
hood.
- We recommend that you install silencers downstream
of the boiler in the flue gas pipe.
Do not overtighten boiler door screws.

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 freestanding 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.
4.11 Heating pump
Speed of rotation and output regulation must correspond
to the requirements of the system. They are to be set
by the heating installation engineer.
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.

Commissioning
4 205 116 / 02
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.
• 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.
