Foreword
This document (CLC/TS 50612:2013) has been prepared by CLC/TC 216 "Gas detectors" together with
CEN/TC 109 "Central heating boilers using gaseous fuels".
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a mandate given to CENELEC by the European Commission and
the European Free Trade Association.
NOTE Commentary text is presented in italic type. It gives background information and does not constitute a
normative element.
Introduction
This Technical Specification is intended as a guide for operatives who, in the course of their professional
activities, are required to measure combustion parameters of gas-fired central heating boilers using
combustion flue gas analysers during any or all of the commissioning, servicing and maintenance of such
appliances.
It is intended to complement the following through a generic approach:
a) the appliance commissioning, servicing and maintenance instructions, and/or
b) national or local regulations or standards.
NOTE 1 A Technical Specification is announced and made available at national level, but conflicting national standards
may continue to exist.
NOTE 2 Existing national or local regulations or standards conflicting with the guidance in this Technical Specification
have precedence over this guidance.
It is not intended that a combustion gas analysis be used as a substitute for commissioning, servicing and/or
maintenance carried out in accordance with the appliance instructions. It is to be regarded and used as a
diagnostic tool to confirm satisfactory combustion to help in the process of carrying out these activities to
ensure the safe and efficient operation of the boiler installation.
In the preparation of this Technical Specification, it has been assumed that the execution of its provisions will
be entrusted to competent operatives, (see Clause 4) for whose use it has been produced.

1 Scope
This Technical Specification provides guidance on the selection, use and maintenance of portable electrical
apparatus conforming to EN 50379-1 [4] and EN 50379-2 [5] or EN 50379-3 [6] designed to measure
combustion flue gas parameters of Type B and Type C gas-fired central heating boilers (hereafter referred to
st nd rd
as boilers) using 1 , 2 or 3 family gases in domestic premises as a diagnostic instrument to assist an
operative:
a) in confirming satisfactory combustion at the time of commissioning, in accordance with appliance
instructions or national or local regulations or standards;
b) in confirming satisfactory combustion at the time of servicing in accordance with national or local
regulations or standards or following servicing in accordance with appliance instructions;
c) in confirming satisfactory combustion following maintenance, in accordance with appliance instructions or
national or local regulations or standards.
NOTE 1 Type B and Type C classification of gas-fired appliances are described in CEN/TR 1749 [1].
NOTE 2 Existing national or local regulations or standards conflicting with the guidance in this Technical Specification
have precedence over this guidance.
NOTE 3 It is not the intention of this Technical Specification to suggest that portable electrical combustion flue gas
analysers are to be used as a substitute for normal service and maintenance carried out in accordance with the appliance
instructions. Clause 9 describes how analysers can be used in conjunction with the appliance instructions.
NOTE 4 EN 50379-1 [4] specifies general requirements for the construction, testing and performance of portable spot
reading apparatus designed to check the combustion performance of heating appliances in domestic premises, using
commercially available fuels.
NOTE 5 EN 50379-2 [5] is for apparatus intended to be used for statutory measurements. In several European
countries, legal requirements exist for the performance of heating appliances (see informative Annex A of
EN 50379-1:2012 [4]). Legal consequences resulting from performance measurements makes for strict requirements for
the apparatus used (see normative Annexes B and C of EN 50379-1:2012 [4]).
NOTE 6 EN 50379-3 [6] is for apparatus intended to be used for non-statutory applications, which allows for reduced
performance requirements for the portable electrical apparatus.
NOTE 7 This Technical Specification deals with the determination of levels of combustion gases such as carbon
monoxide (CO) and carbon dioxide (CO ) in combustion products from boilers. Combustion products from boilers will
contain nitrogen oxides (NO ), predominantly nitrogen monoxide (nitric oxide, NO) and nitrogen dioxide (NO ). This
X 2
Technical Specification does not deal with the measurement of combustion products such as NO and aldehydes.
