•After unpacking the appliance, ensure that all parts are intact and complete as per the supply specifications, and if any
non-conformities are found, contact the Representative that sold the appliance.
•The appliance must be installed by professionally qualified personnel, in conformity with current national and local
standards and the instructions in the manual supplied with the product.
•The appliance must only be used as envisaged in the design. The manufacturer declines all liability for physical injury
or damage to animals or objects caused by errors in installation, adjustments, maintenance or improper use of the
appliance.
•In the event of water leakage, disconnect the appliance from the electric power mains, shut off the water supply and
promptly notify the Technical Services department or other professionally qualified personnel.
•Periodically check that the hydraulic system operating pressure, in cool conditions, is approx. 2 bar. Otherwise contact
the Technical Services department or other professionally qualified personnel.
•In the event of prolonged disuse of the appliance, the following procedure must be observed:
- Set the appliance main switch and the main system switch to "OFF".
- Shut off the fuel and mains water valves.
•This manual is an integral part of the appliance and consequently must ALWAYS accompany the appliance, also in the
event of sale to another Owner or User or transfer to another system. The manual must be kept with care and in the
event of damage or loss, another copy may be requested from the Technical Services department.
•It is recommended to service the appliance at least once a year.
SAFETY WARNINGS AND REGULATIONS
b
•IT IS STRICTLY PROHIBITED to allow children or disabled persons to change settings on the appliance without assistance.
•IT IS STRICTLY PROHIBITED to activate electrical devices or equipment such as switches, telephones, household
appliances etc. if smells of fuel or uncombusted fuel are detected. In this case:
- Open doors and windows to ventilate the room.
- Close the fuel shut-off valve.
- Arrange for prompt intervention of the Technical
Services or other professionally qualified personnel.
•IT IS STRICTLY PROHIBITED to touch the appliance with bare feet or wet parts of the body.
•IT IS STRICTLY PROHIBITED to perform technical interventions or cleaning before disconnecting the appliance from

USE - SYSTEM SUPERVISOR

The aluminium heating units in the range S - AF XL are condensing heat generators, designed to heat rooms, and in
combination with a storage tank, for the production of domestic hot water.
They comprise:
- an aluminium heat exchanger, with low water content and generously sized exchange surface to optimise energy
efficiency and heating output;
- a full pre-mix microflame burner in stainless steel, to guarantee high modulation ratios, combustion stability and low
pollutant emissions (NOx Class = 5);
- a variable speed blower, required for air/gas modulation and mixing;
- a combustion circuit, which can be “type C” (room-sealed) or “type B” (open-flued), with respect to the installation
environment, and on the basis of the flue exhaust configuration on site;
- command-control electronics, which if equipped with outside sensor enables adjustment of the supply temperature on
the basis of the outside temperature. The appliance thus only provides the heat effectively needed by the utility, avoiding
energy waste. The unit is fitted with self-diagnostics with a display of the error codes and operating parameters at the
time of the fault, thereby simplifying tasks for the Technical Services department.
Also, during periods of prolonged disuse or holidays, the appliance remains protected by the Anti-freeze Function, which is
activated automatically when the supply temperature falls to 5°C and shuts off when it returns to 15°C. Obviously the gas
and electrical mains supplies must be active during these periods.
The design phase adopted specific solutions to:
- obtain a constantly optimal air/gas mix;
- minimise dispersions;
- reduce noise levels to a minimum.
The S - AF XL heating units are designed for connection to 0-10 V DC controls and for operation in cascade, in sets of up
to 6 units, and can be equipped with various system accessories, such as the mix bottle or water shut-off valve, and the
ISPESL unit, which all simplify the work of the installer and comply with compulsory italian legal requirements.
DESCRIPTION
S - AF XL appliances are equipped with the following safety, control and adjustment devices:
- Sensor on the appliance heat exchanger, to ensure thermal cut-out when the temperature reading exceeds the maximum
admissible value. This is reset manually via the DSP keypad.
- Water pressure sensor: this intervenes when the hydraulic circuit pressure falls below 0.8 bar.
- Pressure switch: this intervenes when the pressure difference between the flue outlet and air intake exceeds 3 mbar.
- Flue safety sensor: this intervenes when the flue temperature is too high.
- Gas pressure switch: this intervenes if the supply gas pressure falls below 14 mbar.
- Hydraulic circuit diagnostics to protect the heating unit against:
 - temperatureoverload,bycheckingthedifferenceintemperaturesonsupplyandreturn(ΔT);
- inadequate water circulation in the heat exchanger, checking the difference in temperatures between the heat
exchanger sensor and supply sensor.
bWARNING
•If a safety devices trips, this means that there is a potentially hazardous appliance malfunction. In this case contact
Technical Services as soon as possible for assistance.

The system also envisages the option of setting time bands during which the heating unit is set to operate, if there is a
demand for heat, and those during which it remains off, or in ECO mode when fitted with an outside sensor.
There is a maximum of 6 programmable time bands within 24 hours, each of which must be identified by a start time (ON),
and end time (OFF). The minimum interval between each time is half an hour.

ROUTINE CLEANING
Internal cleaning of the appliance and removal of combustion residue from the exchange surfaces are operations required
at least once a year, to be performed by professionally qualified personnel.
This is an essential condition to reduce consumption, pollutant emissions and to keep the stated efficiency and reliability
of the boiler over time.
Before cleaning:
- Set the main switch (IG) of the system and the main
appliance switch (Ip) to “OFF”
- Close the fuel shut-off valves.
EXTERNAL CLEANING
The outer casing should be cleaned with cloths dampened
with water and detergent. In the case of stubborn stains,
dampen a cloth with a mix of 50% water and denatured
alcohol or with special products.
After cleaning, dry the appliance thoroughly.
WARNINGS
•Never use abrasive products, benzene or trichloroethane.
MAINTENANCE
Note that it is a COMPULSORY LEGAL REQUIREMENT THAT THE BOILER SUPERVISOR must arrange for PERIODIC
MAINTENANCE and COMBUSTION EFFICIENCY MEASUREMENTS to be performed by PROFESSIONALLY
QUALIFIED PERSONNEL.
The Technical Services department can fulfil this legal requirement when necessary.
PERIODIC MAINTENANCE guarantees:
- Increased safety
- Reduced operating costs
- Extended lifetime of the boiler
- The reassurance of not receiving considerable penalties in the event of inspections.
