This draft amendment is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 166.

This draft amendment A1, if approved, will modify the European Standard EN 13384-1:2015. If this draft becomes an
amendment, CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for
inclusion of this amendment into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and United Kingdom.
Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are
aware and to provide supporting documentation.

European foreword
This document (EN 13384-1:2015/prA1:2018) has been prepared by Technical Committee CEN/TC 166
“Chimneys”, the secretariat of which is held by ASI.
1 Modification to 1, 3, 4, 5, 6, 7, 8, 9 and Annex B
Replace
“heating appliance”
By
“combustion appliance”.
2 Modification to 5.5.2
Replace Clause 5.5.2 with the following text:
"5.5.2 Flue gas mass flow and combustion air mass flow
5.5.2.1 Flue gas mass flow and combustion air mass flow at nominal heat output of the
combustion appliance
For the calculation of pressure and temperature values according to relationships of Formulae (1), (2),
(2a), (3), (4), (5), (5a) and (6) the flue gas mass flow and combustion air mass flow at nominal heat output
conditions for the combustion appliance shall be obtained.
If the data are not available the flue gas mass flow, combustion air mass flow and the volume
concentration of CO can be determined from the formulas in Tables B.1, B.2 or B.3.
If the chimney is connected to a multi-fuel combustion appliance the calculation and dimensioning should
be carried out by considering all the fuels suited to the appliance.
In the case of combustion appliances with a draught diverter the flue gas mass flow downstream of the
draught diverter shall be used.
 
The flue gas mass flow and combustion air mass flow of an open fire place depends on its opening.
m m
B
For the calculation use the following formula:

m = f ⋅ A , in kg/s (8)
mf F

mm= , in kg/s (8a)
B
where
f 2
mf is the mass flow factor of an open fire place, in kg/(s·m );
A 2;
F is the cross section of the opening of the open fire place, in m
For open fire places with an opening height less than or equal its width f = 0,139 kg/(s·m ).
mf
For open fire places with an opening height greater than its width f = 0,167 kg/(s·m ).
mf
The CO -content of the flue gas for open fire places may be taken as σ(CO ) = 1 %.
2 2
5.5.2.2 Flue gas mass flow and combustion air mass flow at the lowest permissible heat output
If the combustion appliance is designed to operate under modulating conditions an additional check shall
be conducted for the pressure and temperature requirement of the flue gas mass flow and combustion
air mass flow at the lowest possible and permissible heat output of the combustion appliance. If the
manufacturer does not provide flue gas data and combustion air mass data for the lowest heat output use
a mass flow of one third of the flue gas mass flow and combustion air mass flow at nominal heat output.
5.5.2.3 Flue gas mass flow and combustion air mass flow at the maximum draught or minimum
differential pressure of the combustion appliances
For the calculation of maximum draught or minimum positive pressure in a chimney the flue gas mass
flow and combustion air mass flow at maximum draught or minimum differential pressure of the
combustion appliance shall be obtained from the manufacturer of the combustion appliance if
appropriate.
5.5.2.4 Flue gas mass flow with secondary air
If secondary air is supplied by a draught regulator or draught diverter the air flow shall be calculated
according to 6.3 depending on the actual difference of the pressure in the room of installation of the
combustion appliance and the chimney or connecting flue pipe."
