The unit should only be operated when it is in full working order. It must be operated in
accordance with the instructions, observing safety precautions, and you should ensure
you are aware of the potential hazards. The inspection and cleaning intervals in the
operating instructions must be observed. Ensure that any faults which might impair
safety are rectified immediately.
The manufacturer or supplier is not liable for any damage resulting from non-permitted
uses.
Only original spare parts or specific alternative spare parts authorised by the
manufacturer may be used. Any kind of change or modification made to the product
will invalidate its manufacturer’s CE conformity. In such cases, the product will need to
undergo new hazard evaluation procedures by the operator. The operator will then be
fully responsible for the declaration of conformity according to the valid guideline(s) for
the product and will need to attach the new CE label to the device. This person will
then assume all of the rights and responsibilities of a manufacturer.
2.4.1 The Clean Air Act 1993 and Smoke Control Areas
Under the Clean Air Act local authorities may declare the whole or part of the district of
the authority to be a smoke control area. It is an offence to emit smoke from a
chimney of a building, from a furnance or from any fixed boiler if located in a
designated smoke control area. It is also an offence to acquire an „unauthorised
fuel“ for use within a smoke control area unless it is used in an „exempt“ appliance
(„exempted“ from the controls which generally apply in the smoke control area). The
Secretary of State for Environment, Food and Rural Affairs has powers under the Act
to authorise smokeless fuels or exempt appliances for use in smoke control areas in
England. In Scotland and Wales this power rests with Ministers in the devolved
administrations for those countries. Separate legislation, the Clean Air (Northern
Ireland) Order 1981, applies in Northern Ireland. Therefore it is a requirement that
fuels burnt or obtained for use in smoke control areas have been „authorised“ in
Regulations and that appliances used to burn solid fuel in those areas (other than
„authorised“ fuels) have been exempted by an Order made and signed by the
Secretary of State or Minister in the devolved administrations.
Further information on the requirements of the Clean Air Act can be found here: http://
smokecontrol.defra.gov.uk
Your local authority is responsible for implementing the Clean Air Act 1993 including
designation and supervision of smoke control areas and you can contact them for
details of Clean Air Act requirements.

2.4.4 Non-permitted fuels
The use of fuels not defined in the "Permitted fuels" section, and particularly the
burning of refuse, is not permitted.
CAUTION
In case of use of non-permitted fuels:
Burning non-permitted fuels increases the cleaning requirements and leads to a
build-up of aggressive sedimentation and condensation, which can damage the
boiler and also invalidates the guarantee. Using non-standard fuels can also lead
to serious problems with combustion.
For this reason, when operating the boiler:
❒ Only use permitted fuels
2.5 Qualification of operating staff
CAUTION
If unauthorised persons enter the installation room:
Risk of personal injury and damage to property
❒ The operator is responsible for keeping unauthorised persons, in particular

Ventilation of the boiler room
Ventilation air for the boiler room should be taken from and expelled directly outside,
and the openings and air ducts should be designed to prevent weather conditions
(foliage, snowdrifts, etc.) from obstructing the air flow.
Unless otherwise specified in the applicable building regulations for the boiler room,
the following standards apply to the design and dimensions of the air ducts:
ÖNORM H 5170 - Construction and fire protection requirements
TRVB H118 - Technical directives on fire protection/prevention
2.7.3 Requirements for central heating water
Austria:
Germany:
Switzerland:
Italy:
ÖNORM H 5195
VDI 2035
SWKI 97-1
D.P.R. no. 412
NOTICE! Note on filling with make-up water: Always bleed the filling hose before
connecting, in order to prevent air from entering the system.
Observe the standards and also follow the recommendations below:
❒Max. cumulative value for alkaline earth: 1.0 mmol/l or 100 mg/l (equivalent to
5.6 dH)
❒ Use prepared water which complies with the standards cited above for filling and
makeup water
❒ Avoid leaks and use a closed heating system to maintain water quality during
operation
2.7.4 Notes for using pressure maintenance systems
Pressure maintenance systems in hot-water heating systems keep the required
pressure within predefined limits and balance out volume variations caused by
changes in the hot-water temperature. Two main systems are used:
Compressor-controlled pressure maintenance
In compressor-controlled pressure maintenance units, a variable air cushion in the
expansion tank is responsible for volume compensation and pressure maintenance. If
the pressure is too low, the compressor pumps air into the tank. If the pressure is too
high, air is released by means of a solenoid valve. The systems are built solely with
closed-diaphragm expansion tanks to prevent the damaging introduction of oxygen
into the heating water.

Note on standards
2Safety
Design information
16 Fröling GesmbH | A-4710 Grieskirchen, Industriestraße 12 | www.froeling.com

Pump-controlled pressure maintenance
A pump-controlled pressure maintenance unit essentially consists of a pressure-
maintenance pump, relief valve and an unpressurised receiving tank. The valve
releases hot water into the receiving tank if the pressure is too high. If the pressure
drops below a preset value, the pump draws water from the receiving tank and feeds it
back into the heating system. Pump-controlled pressure maintenance systems with
open expansion tanks (e.g. without a diaphragm) introduce ambient oxygen via the
surface of the water, exposing the connected system components to the risk of
corrosion. These systems offer no oxygen removal for the purposes of corrosion
control as required by VDI 2035 and in the interests of corrosion protection should not
be used.
2.7.5 Return lift
If the hot water return is below the minimum return temperature, some of the hot water
outfeed will be mixed in.
CAUTION
Risk of dropping below dew point/condensation formation if operated without
return temperature control.
Condensation water forms an aggressive condensate when combined with
combustion residue, leading to damage to the boiler.
Take the following precautions:
❒ Regulations stipulate the use of a return temperature control.
➥The minimum return temperature is 60 °C. We recommend fitting some
sort of control device (e.g. thermometer).
2.7.6 Combination with storage tank
You can find more detailed information about storage tank design in the boiler
assembly instructions.
NOTICE! See "Design Information" section in the assembly instructions SP Dual
compact
2.7.7 Chimney connection/chimney system
EN 303-5 specifies that the entire flue gas system must be designed to prevent,
wherever possible, damage caused by seepage, insufficient feed pressure and
condensation. Please note in this respect that flue gas temperatures lower than 160K
above room temperature can occur in the permitted operating range of the boiler.
NOTICE! Please see the technical data contained in the assembly instructions for
further information about standards and regulations as well as the flue gas
temperatures when clean and the other flue gas values!
