Foreword

This document (prEN 16510-2-4:2013) has been prepared by Technical Committee CEN/TC 295 “Residential

solid fuel burning appliances”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 12809:2001.

EN 13240:2001, EN 13229:2001, EN 12815:2001 and EN 12809:2001 will be totally superseded by EN 16510

series. The revision of these European Standards takes into account the comments received at their 5-year

review.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive 89/106/EEC, see informative Annex ZA, which is an integral part of this

document.

The structure of EN 16510, Residential solid fuel burning appliances, is as follows:

 Part 1: General requirements and test methods;
 Part 2-1: Roomheaters;
 Part 2-2: Inset appliances including open fires;
 Part 2-3: Cookers;
 Part 2-4: Independent boilers – Nominal heat output up to 50 kW.

Principally it is possible to add further parts 2 at a later stage in order to cover other residential solid fuel

burning appliances such as pellet stoves or slow heat release appliances.

This Part 2-4 is to be used in conjunction with the latest edition of EN 16510-1 and its amendments. It was

established on the basis of prEN 16510-1:2013.

This Part 2-4 supplements or modifies the corresponding clauses in EN 16510-1, so as to convert that

publication into the European Standard: Residential solid fuel burning appliances – Requirements and test

methods for independent boilers – Nominal heat output up to 50 kW .

When a particular subclause of Part 1 is not mentioned in this Part 2-4, that subclause applies as far as is

reasonable. When this Part 2-4 states "addition", "modification" or "replacement", the relevant text in Part 1 is

to be adapted accordingly.
NOTE The following numbering system is used:

 subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;

 unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including those

in a replaced clause or subclause;
 additional annexes are lettered AA, BB, etc.

NOTE 101 For convenience of testing hopper fed appliances, it is permissible to operate the appliance at between 50 %

and 100 % of the claimed water heating output for part of the pre-test period, and to extend the pre-test period so that the

total mass of fuel consumed is the same as would be consumed by operating continuously at the claimed water heating

output. If the appliance is operated at reduced water heating output during part of the pre-test period, the appliance

controls and water flow rate should be adjusted to give the claimed water heating output for a period of at least 30 min

prior to the end of the pre-test period.
A.4.8.3 Recovery test period
prEN 16510-1:2013, A.4.8.3, is applicable with the following modification.
Replacement:

At the end of the slow combustion test period, reset the appliance controls in accordance with the appliance

manufacturer's operating instructions to give the nominal heat output. Adjust the water flow rate to that

required for nominal heat output operation. De-ash and/or refuel the appliance as necessary to allow the fire

to recover. Record whether the fire recovers in accordance with 7.5 and record the time taken.

A.4.9 Safety tests
prEN 16510-1:2013, A.4.9, is not applicable.
Addition of the following new subclauses
A.4.101 Test for fan cut-out safety device
A.4.101.1 General

This test is applicable only to hopper fed appliances, burning small anthracite, which are fitted with a forced

draught fan providing the combustion air supply.

Install the appliance in accordance with A.2.2 taking into account the manufacturer’s installation instructions.

Connect the appliance to the test measurement section in accordance with A.2.3 but with the following

modification:

 install a sliding flue cut-off damper assembly immediately above the appliance flue outlet as shown in

Figure A.101. The hole in the damper plate shall be 5 % of the cross sectional area of the fluepipe

recommended by the manufacturer.

The test shall be started from cold and consist of two parts, namely, an ignition and pre-test period, and a test

period.
A.4.101.2 Ignition and pre-test period

Fill the hopper and ignite the fire in accordance with the manufacturer’s operating instructions and run the

appliance for a preliminary period of about 3 h with the applied draught set at (12 ± 2) Pa. Set the primary air

control thermostat to give a flow temperature (16 ± 3) K above the return temperature, which shall be

controlled between 50 °C and 55 °C. Adjust the water flow rate to give a water heating output of approximately

50 % of the manufacturer’s claimed nominal water heating output.

At the end of the 3 h preliminary period, maintain the thermostat at the previously established setting and

reduce the water heating output, by reducing the water flow rate in stages over a few hours, to give (10 ± 2) %

of the manufacturer’s claimed nominal water heating output. Adjust the applied draught so that the static

pressure in the measurement section is set to the value required for slow combustion as stated in 6.6 and

maintain within ± 1 Pa of this value.

A.4.101.3 Test period

Refill the hopper at the start of the test period to between one half and three-quarters of its capacity and allow

it to operate for 16 h under the conditions established at the end of the pre-test period (see A.4.101.2).

Measure the water flow rate in accordance with A.4.5 and maintain it within ± 5 % of the value obtained at the

end of the pre-test period.

Record the inlet and outlet water temperatures in accordance with A.4.5 and check that the mean water

heating output is within the limits of (10 ± 2) % of the nominal water heating output.

After 16 h, carry out the flue blockage test immediately on commencement of the next “fan-on” period, by

pushing the blockage damper securely into position to simulate a chimney blockage condition. Measure and

record the time from blockage of the flue to operation of the fan cut-out safety device. Remove the blockage

damper to clear the flue.
