1. Introduction 

Thank you for the confidence you have shown to us by purchasing our central heating boiler. 
In order to use the boiler to the utmost  correctly and safely, and above all economically, read 
thoroughly these instructions before continuing with installation. 
 

The appliances must be installed by a competent person, who is responsible for adhering to 
the existing regulations, rules and guidelines. 

1.1. Applicable documents 

The following additional documents are provided with the appliance: 
 

For the owner of the system: 

Instructions for use 
Warranty card 

For the qualified technician: 

Instructions for installation 
Electrical drawing for the appliance 

1.2. Retention of documents 

Please pass on this installation manual to the owner of the system. The owner should retain the 
manuals so that they are available when required. 

1.3. Introduction 

TERMO-Extra and TERMO-Blok are economical central heating boilers that may be used as an 
independent or additional source of heat. 
TERMO-Extra and TERMO-Blok boilers offer you a possibility to reduce the power of the  heater if 
necessary. The power may be switched on automatically  when necessary with built-in step regulator 
or manually with switches on the control board. In this way it is possible to adapt the boiler to the 
utmost to circumstances on the spot. 
The boiler operates on a principle of rapid heating smaller water quantities, so that exploiting energy is 
already 100%. 
 
They are particularly suitable for heating smaller business premise, where you are short of space 
(small apartments, efficiency apartments, representation offices, smaller coffee-shop spaces etc.) or 
for heating larger spaces in early season when the main boiler is over dimensioned. 
TERMO-Extra boilers are manufactured only with upper connections. Temperature operation area is 
from 20 

o

C to 90 

o

C. 

TERMO-Extra and TERMO-Blok are designed in such a way that in apartment-contained central 
heating they can fit well with your furniture. 

1.4. Heating curves 

1.4.1. Availability of heating curves 

Use of heating curves, temperature compensation, is limited to Termo Extra boilers with options 

C

 and 

W

, Termo Blok boilers with option 

C

 and Termo PTV boilers.
