Procedure for additionally filling the heating system with water:
1. Disconnect the boiler from electrical voltage
2. Slowly open the valve for additional filling and monitor manometer on the control panel of the boiler.
3. Set the system pressure to the necessary value (according to the heating system, recommended 1.0 – 1.5 bar)
4. Close the valve for additional filling
5. Connect the boiler to the electricity network and connect the boiler again

2.5 Maintenance and service
Regular maintenance is very important for reliable operation, to achieve a long service life, and efficient combustion. We
consistently recommend the user to contact a service organisation in the place of residence and to ensure regular inspections
of the boiler after one year of operation (see chapter: Warranty and Warranty Terms). The service technician will for example,
inspect the control and security elements of the boiler, inspect the tightness of the gas and water distribution or the cleaning
of the burner and the exchanger of burnt dust particles, etc.
For error-free operation of the heating system, it is also necessary to regularly inspect the initial water pressure in a cold
condition. In the case of a decrease of pressure below 0.8 bar, it is necessary to additionally fill the heating system.
2.5.1 Additionally filling the heating system
Adding of water to the heating system (system pressurizing) must be performed via the top-up valve, which forms part of
the heating system. Water for filling must fulfil certain parameters, see chapter 3.8.
During additional filling it is necessary to take the following conditions into consideration:
2.6 Warranty and warranty terms
The producer is not liable for any mechanical damage to individual components by rough handling, for damage caused by

The warranty is also not applicable to defects caused by non compliance with the binding notifications and terms stated in
individual parts of this manual.
The warranty is not applicable to non-standardized relations in distribution networks (variation of electrical voltage – in
particular voltage peaks, pressure and cleanliness of gas, etc.), defects to equipment outside the boiler that influence activity,
improper collection of burnt gases, dirt in the combustion air, damage from outside influences, mechanical damage, storage,
transport and defects originated by natural disasters.
In such cases the service organisation may require that the client pays for the repair.
THERMONA Ltd provides a warranty according to the stated in the Warranty Certificate delivered with the product.
Terms for application of the warranty:

from www.thermona.cz
2. Documentation for all records of warranty repairs and annual inspections of boilers is in the appendix to this manual.
3. Submitting completed and confirmed warranty certificate and protocol on commissioning into the operation of THERM
products
a) the pressure of utility water supplied into the boiler must be higher than the water pressure in the heating
system (otherwise the heating water can flow back to the water mains!)
b) the additional filling of water is necessary to be done exclusively under a cold status (the temperature of
the heating water in the boiler is a maximum of up to 35 °C)
