Residential solid fuel burning appliances - Part 2-6: Mechanically by wood pellets fed roomheaters, inset appliances and cookers
This part 2-6 of a European Standard series shall be applicable to space heaters, inset appliances and cookers fired by wood pellets, mechanically fed up to 50 kW nominal heat output. These appliances typically use auxiliary energy which is measured in this standard as well.
For inset pellet appliances and especially their testing, additional information is necessary from prEN 16510 2 2.
For pellet cookers and especially their testing, additional information is necessary from prEN 16510 2 3.
Non mechanically fed appliances burning solid mineral fuels, peat briquettes and natural or manufactured wood logs are not included in this European Standard, but are covered by prEN 16510 2 1 to prEN 16510 2 5.
NOTE These appliances may have an integral fuel hopper or be combined with an external fuel hopper.
This European Standard should be used in conjunction with prEN 16510-1.
The appliances covered by this part 2-6 provide heat into the space where they are installed. They may be operated with either natural draught or fan-assisted combustion air. Where fitted with a boiler, they can also provide domestic hot water and/or central heating. These appliances burn wood pellets only, in accordance with the appliance manufacturer's instructions. They only operate with the firedoors closed.
NOTE A fan-assisted appliance does still operate under negative pressure in the flue gas system.
This European Standard specifies requirements relating to the design, manufacture, construction, safety and performance (efficiency and emissions), instructions and marking together with associated test methods and test fuels.
This European Standard shall not applicable to appliances:
— with boiler intended for water systems having water temperatures above 110°C and 3 bar; and
— with boiler intendend for water systems having direct contact with sanitary hot water;
— intended to be used with a pure horizontal exhaust (through the building wall);
— with flue gas condensation in the appliance;
— switching on / off for part load operation.

After 5.9.2 add the following subclause.
5.9.601 Tightness of type CM 50, CC 50 and CC 50+ (see Table 1)
For appliances of type CM50, CC50 and CC50+ (see Table 1) the test according to A.4.11.2.2 is carried out
at an overpressure of 50 Pa.For appliances of type CM50, CC50 and CC50+ (see Table 1) the following requirements shall be met.

prEN 16510-2-6:2021 (E)
The mean value of CO concentration as measured in the combustion products of the appliance, given in
ppm is measured during the test at nominal heat output according to A.4.7 and at part load heat output
according to A.4.8 (combustion air control devices are set at the settings specified by the manufacturer).
The product of the CO concentration in the flue gas [ppm] (at 13 % O ) and the leakage of the appliance
[Nm3/h] determined according to A.4.11.2.2, A.4.11.2.3 and A.4.11.2.4 shall not exceed the value of 2 400
[ppm Nm /h] at nominal heat output and at part load heat output (if specified by the manufacturer).
For CC50+ appliances the leakage shall not exceed 1 Nm /h.Add the following new subclauses:
5.601 Safety test for spillage of combustion gas and discharge of embers
When operated under the test conditions described in A.4.7 to A.4.9 there shall not be any potentially
harmful spillage of flue gases from the appliance into the room and embers shall not fall out.
5.602 Temperature in the fuel hopperWhen tested during the temperature safety test in accordance with A.4.10.3 the temperature in any fuel
hopper shall not exceed the ambient temperature by more than 65 K at normal use and 85 K at abnormal
circumstances (see Annex FA).For necessary measuring points see Annex FB.
5.603 Safety against back burning through the fuel conveyor system
The appliance shall have a safety system to ensure that the fuel shall not burn back from the retort to the
fuel hopper. Operation of any of the safety systems shall stop the fuel supply (refer to Annex FB for
examples).5.604 Risk assessment of the appliance fired by wood pellets
A risk assessment of the appliance fired by wood pellets shall be performed by the manufacturer.
EN ISO 12100, ISO/TR 14121-2 or CLC Guide 32 give information on how to carry out the risk
assessment.Completeness, correctness and plausibility of the risk analysis of the manufacturer shall be verified by a
NB on the basis of the risks given below and using the guidance Annex FA. This verification is mainly a
documental control and may influence the details (e.g. the detailed measuring points in the hopper) of
the safety tests (A.4.10).The risk assessment shall cover each relevant risk, especially the following:
— backburn into the hopper;
— combustion in the conveying system;
— malfunction of combustion air supply;
— blockage of the chimney;
— risk of explosion;
— single failure of electrical components.
For all electric hazards, LVD shall be followed.

Force majeure risks shall not be taken into consideration (i.e. any event or occurrence which is outside
the reasonable control of the manufacturer concerned and which is not attributable to any act or failure
to take preventative action).5.605 Safety shutdown in case of an unsafe situation
If an appliance shuts down for the reason of an unsafe situation this shall be such that a restart shall only
be possible manually.For these risks, an automatic restart shall not be allowed.
6 Appliances Performance requirements in relation to the appliance operation
prEN 16510-1:2021, prEN 16510-2-2:2021 and prEN 16510-2-3:2021, Clause 6 shall be applicable as
necessary with the following modification(s).6.2.2 Flue gas temperature at safety test
prEN 16510-1:2021, 6.2.2 shall be applicable with the following modification(s).
Replace 6.2.2 by the following:
When tested in accordance with A.4.10.3 the flue gas temperature shall be measured and the mean value
of the last 30 min of the test is determined. This value shall not exceed the designated Tclass of the
chimney. The chimney designation shall be at least T200 G.NOTE National installation and building regulations are expected to be met in this particular item (often a T400
G is required in these regulations)6.3.5 Particulate matter (PM/PME) emissions
prEN 16510-1:2021, 6.3.5 shall be applicable with the following modification(s).
Replace 6.3.5 by the following:
At all heat output rates specified by the manufacturer the mean particulate matter concentration
expressed as mg/m3 for PM/PME calculated to 13 % oxygen (O ) content, (dry, 273 K, 1 013 hPa) in the
flue gas is measured, and it shall be less than or equal to the manufacturer’s specified value expressed in
mg/m .During each nominal test measure the PM/PME according to the following procedure:
— 30 min operation without measurement;— 30 min filter 1st sampling and appropriate analysis;
— 30 min operation without measurement (filter may be exchanged in that period);
— 30 min filter 2nd sampling and appropriate analysis;— 30 min operation without measurement (filter may be exchanged in that period);
— 30 min filter 3rd sampling and...
