gaseous fuels and having nominal out put capacity from 4 to 400 KWatts.  
2. In these Technical regulations the terms used shall have the following meaning:  
hot-water boiler (hereinafter – th e boiler) – the device that cons ists of the body with convection 
heating surfaces and the firing unit, which is designed to heat water using energy released in the 
course of fuel combustion;  
the efficiency factor (hereinafter - the coefficient) – the ratio of the amount of heat  transferred to 
the water in the boiler, to the amount of heat  released in the course  of fuel combustion on 
condition of the same quantity of fuel consumed in the same period of time;

Permissible values of the coefficient  
4. Permissible values of the coefficient for opera tion of the boiler with nominal heat generating 
capacity and average temperature of water in th e boiler of 70° C and during the operation of the 
boiler at the 30-percent work lo ad for average temperatures de pending on the type of the boiler 
are shown in Annex 1.  
5. Putting into operation the built-i n boilers and/or boilers for residential housing is allowed 
provided that the value of coefficients at th e nominal heat generating capacity and at the 30-
percent work load is not less than  4 percent of the coefficients se t for standard/regular boilers.  
6. At the time of operation of boilers designed for heating of housing/rooms and for supplying 
hot drinking water, the permissible value of th e coefficient concern only those functions of the 
boiler which are related to heating.  
Conformity assessment procedures  
7. Producer, or his authorized representative, sha ll carry out assessment of conformity of boilers 
to requirements concerning their efficiency coe fficients by applying procedures (modules for 
assessment of conformity) establ ished by the Technical regulations  on modules for assessment of 
conformity and requirements con cerning application of the nationa l mark of conformity, which 
are used in the technical regul ations approved by Resolution of the Cabinet of Ministers of 
Ukraine of 7 October 2003, # 1585 (Official ga zette of Ukraine, 2003, # 41, p. 2175; 2007, # 1, 
p. 31).  
8. To carry out an assessment of  conformity of the coefficient of serially manuf actured boilers 
fired with  gaseous fuels, at the choice of the producer there will be used module B (type 
examination) in combination with module C (type conformity), module D (assurance of 
production process quality), module E (assurance of product quality), or module F (product 
examination).  
9. A procedure of assessment of conformity of th e coefficient of boilers produced individually or 
in small quantities and fired with gaseous fu els shall be carried out  by applying module G 
(individual product unit examination).  
10. To carry out an assessment of conformity of the coefficient of boilers of serial production 
fired with  liquid fuels, at the choice of the producer there will be used module B (type 
examination) in combination with module C (t ype conformity) or module D (assurance of 
production process quality), or module E (assurance of product quality).  
11. After conducting procedures of assessment of conformity, the producer or his authorized 
representative shall prepare a d eclaration of conformity using th e form presented in Annex 2 and affix to each product the national mark of confor mity in accordance with requirements of these 
Technical regulations.  
Producer, or his authorized representative, is required to keep copies of the certificate of 
conformity and copies of the declaration of  conformity together with the technical 
documentation during ten years after the manufacturi ng of the last product unit, and to produce it 
for examination in cases specified by legislation.  
In case of absence of the producer or his authori zed representative, the responsibility for keeping 
copies of the certificate of c onformity, declaration of conform ity and technical documentation 
shall be assigned to the person who put the produc ts into circulation in the domestic market.  
Labeling of boilers  
12. Depending on the results of th e application of conformity assessment procedures, producers 
may apply a system of markings denoting energy e fficiency of boilers. Such a system shall be 
introduced for boilers the efficiency coefficient of  which is higher than that of standard boilers 
and is specified in section 4 of  these Technical regulations.  
One asterisk sign ("*") shall be affixed to boile rs the efficiency coefficients of which under 
nominal heat generating capacity and partial work load are not less than the efficiency 
coefficient for standard boilers.  
Two asterisks ("**") will be affixed to the bo iler the efficiency coefficient of which under 
nominal heat generating capacity and partial work load is greater by three points (but not more 
than by six points) than the effici ency coefficient for a standard boiler (with each further increase 
by three points one more asterisk "*" will be added as provided in Annex 3).  
Affixing any other marks that can be confused with those specified in this section is not allowed.  
13. A boiler, conformity of which has been verifi ed under the established applicable procedure, 
shall bear the national mark of conformity affi xed to it by the producer or by his authorized 
representative.  
14. The description of the national mark of conformity and rules for its application are approved 
by Resolution of the Cabinet of Ministers of  Ukraine of 29 November 2001 # 1599 (Official 
gazette of Ukraine, 2001, # 49, p. 2188).  
15. It is prohibited to affix to the boilers other marks in form similar to the national mark of 
conformity.  
16. If it has been established that the national ma rk of conformity is a pplied in violation of 
requirements of the legislation, the producer or  his authorized representative or a person 
responsible for putting the product into circulation, shall be required to take measures to stop the 
violation on conditions specified by the centra l executive authorities in accordance with 
legislation, ensure conformity of the products with requirements specified in these Technical 
regulations and to verify this conformity in  accordance with the established procedure.  
17. The boiler technical data plate is to bear the national mark of conform ity and to contain the 
following data:  
name of the producer or hi s identification number;  firm name and conventional coding/denomination of the boiler;  
type and nominal gas pressure;  
nominal heat generating capacity or heating capacity of the boiler;  
serial number of the boiler and date  (month and year) of production.  
On boilers equipped with electric devices, in add ition to the specified info rmation, there shall be 
specified:  
Nominal voltage;  
Type of electric current (direct or alternating);  
The symbol denoting the degree of prot ection from electric current impact.  
Depending on the intended use and design of the boiler other information, required for its
