2. Installation
2.1 General Instructions
BOILER INSTALLATION MUST ONLY BE PERFORMED BY QUALIFIED PERSONNEL, IN ACCORDANCE WITH
ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MANUAL, THE PROVISIONS OF CURRENT LAW, THE PRESCRIPTIONS OF NATIONAL AND LOCAL STANDARDS AND THE RULES OF PROPER WORKMANSHIP.
2.2 Place of installation
The boiler unit must be installed in a specific room with ventilation openings to the outside as prescribed by current regulations. If there are several burners or suction units that can work together in the same room, the ventilation openings
must be sized for simultaneous operation of all the units. The place of installation must be free of flammable materials
or objects, corrosive gases, powders or volatile substances that, conveyed by the burner fan, can obstruct the internal
lines of the burner or the combustion head. The room must be dry and not exposed to rain, snow or frost.
A
2.3 Plumbing connections
If the unit is enclosed in a cabinet or mounted alongside, a space must be provided for removing the casing
and for normal maintenance operations.
The heating capacity of the unit must be previously established by calculating the building's heat requirement according
to current regulations. The system must be provided with all the components for correct and regular operation. It is advisable to install on-off valves between the boiler and heating system allowing the boiler to be isolated from the system
if necessary.
The safety valve outlet must be connected to a funnel or collection pipe to prevent water spurting onto the floor
B
Before installation, carefully wash all the pipes of the system to remove any residuals or impurities that could affect proper operation of the unit.
Carry out the relevant connections according to the diagram in cap. 4.1 "Dimensions, connections and main components" and the symbols given on the unit.
Water system characteristics
In the presence of water harder than 25° Fr (1°F = 10ppm CaCO3), use suitably treated water in order to avoid possible
scaling in the boiler. Treatment must not reduce the hardness to values below 15°F (Decree 236/88 for uses of water
intended for human consumption). Treatment of the water used is indispensable in case of very large systems or with
frequent introduction of replenishing water in the system.
B
Antifreeze system, antifreeze fluids, additives and inhibitors
The boiler is equipped with an antifreeze system that turns on the boiler in heating mode when the system delivery water
temperature falls under 6°C. The device will not come on if the electricity and/or gas supply to the unit are cut off. If it
becomes necessary, it is permissible to use antifreeze fluid, additives and inhibitors only if the manufacturer of these
fluids or additives guarantees they are suitable for this use and cause no damage to the heat exchanger or other components and/or materials of the boiler unit and system. It is prohibited to use generic antifreeze fluid, additives or inhibitors that are not expressly suited for use in heating systems and compatible with the materials of the boiler unit and
system.
in case of overpressure in the heating circuit. Otherwise, if the discharge valve cuts in and floods the room,
the boiler manufacturer cannot be held liable.
Do not use the water system pipes to earth electrical appliances.
If water softeners are installed at the boiler cold water inlet, make sure not to reduce the water hardness too
much, as this could cause early deterioration of the magnesium anode in the hot water tank.

Heating system output adjustment
On PEGASUS D Ki 100 boilers, the firebox heating power and therefore the heat output delivered to the heating water
can only be adjusted by means of the main burner through the gas valve, (see fig. 19). The diagrams given in the section
cap. 4.2 "Pressure losses" indicate the variation in heat output delivered to the water according to the change in burner
operating pressure. Being able to adjust boiler output to the actual heating requirements means above all reducing heat
losses, and therefore obtaining fuel saving. Also, with the variation in output, also regulated by the provisions, the boilers
keep their efficiency levels and combustion characteristics practically unchanged
This operation is carried out with the boiler working and the water storage tank heated.
1. Using a small screwdriver, remove the secondary operator protection cap 5 of the gas valve of fig. 19.
2. Connect a manometer to the pressure point 2 (fig. 19) located below the gas valve, and turn the boiler thermostat
knob to the maximum value.
3. Adjust the pressure to the required value by means of the screw 6 (fig. 19), referring to the diagrams given in section
cap. 4.2 "Pressure losses".
4. Then turn the burner on and off 2 or 3 times by means of the control thermostat and check that the pressure value
is that just set; otherwise, another adjustment must be made to bring the pressure to the correct value.

vent valve on the boiler and any vent valves on the system.
If, after correctly carrying out the lighting procedures, the burners do not light and the message A01 appears
on the display, wait about 15 seconds and then press the RESET pushbutton. The reset controller will repeat
the lighting cycle. If the burners do not light after several of attempts, consult the "Troubleshooting" section.
In case of a power failure while the boiler is working, the burners will go out and relight automatically when the
power is restored.
Checks during operation
• Make sure the fuel circuit and water systems are tight.
• Check the efficiency of the flue and fume ducts during boiler operation.
• Make sure the water is circulating properly between the boiler and the systems.
• Check correct lighting of the boiler, by turning it on and off several times.
• Make sure the fuel consumption indicated on the meter matches that given in the technical data table on cap. 4.3
"Technical data table".
• Check the correct flow of domestic hot water with the Δt given in the technical data table: do not trust measurements
made with empirical systems. The measurement should be made with special instruments and as close as possible
to the boiler, also considering the heat lost from the pipes.
• During heating operation, make sure circulating pump stops when a hot water tap is opened, and that there is regular
production of domestic hot water.

Hot water tank cleaning (to be carried out every 2-3 years, depending on water aggressiveness)
• Remove the front panel of the hot water tank (6 - fig. 21).
• Close the hot water tank on-off valves and open the drain cock.
• After draining, remove the inspection flange and carry out cleaning. Use specific products available on the market.
Do not use metal tools to remove the scale.
• After cleaning, refit the inspection flange and hot water tank front panel and open the on-off valves.
Magnesium anode
The degree of deterioration of the magnesium anode (4 - fig. 21) can be checked directly from the outside by unscrewing
it from the hot water tank flange (after turning off the domestic hot water supply and draining the hot water tank).
This check is advisable at least once a year.
If the water is very hard, above 20 degrees French, install a water softener in the system.
Draining the hot water tank and heating system
• To drain the hot water tank, use the drain cock 233 of fig. 25 after closing the valves for filling from the water system;
use a hot water drawing point (washbasin, shower, etc.) as a vent.
• To drain the heating system completely, use the cock 275 of fig. 25 after releasing the shutters of the two non-return
valves detail 179 of fig. 25 (also see fig. 22). Use the radiator valves as vents.
If the boiler is connected to the system by service gate valves, check their complete opening. If the boiler is positioned higher than the radiators, the part of the system including the radiators must be drained separately.
• To drain just the water contained in the boiler, close the on-off valves and fully open the cock (255 - fig. 25). Then
release the shutters of the non-return valves (179 - fig. 25). Lastly, open the cock 197 of fig. 25).

obr. 4 - Kotel odpojený od elektrického napájení
Systém ochrany proti mrazu nefunguje, jestliže je odpojeno elektrické a/nebo plynové napájení kotle. Při
B
dlouhých odstávkách v zimním období doporučujeme vypustit všechnu vodu z kotle, užitkovou vodu i vodu z
topného sytému, aby mráz zařízení nepoškodil; nebo můžete vypustit pouze užitkovou vodu a do topného
systému dát vhodný prostředek proti zamrznutí, jak je uvedeno v sez. 2.3.
