Residential solid fuel burning appliances - Part 2-7: Combination appliances fired by wood logs and pellets

This document is applicable to space heaters, inset appliances and cookers intended for mechanical fuelling with wood pellets and for manual fuelling with other solid fuel. They can be freestanding or inset appliances.
The intended use of the appliances is space heating in residential buildings and can be cooking. They can be fitted with a boiler (integral part of the appliance containing water to be heated up) for the supply of hot water for central heating systems.
These appliances typically use auxiliary energy which is measured in this standard as well. They are operated with natural draught and can be fan-assisted.
NOTE 1   A fan-assisted appliance does still operate under negative pressure in the flue gas system.
For inset appliances and especially their testing additional information can be necessary from EN 16510-2-2.
These appliances burn wood pellets and wood logs only, in accordance with the appliance instructions. They only operate with the firedoors closed.
NOTE 2   These appliances can have an integral fuel hopper or be combined with an external fuel hopper.
These appliances can be fitted with a single or double combustion chamber having a single flue gas outlet.
This document specifies procedures for assessment and verification of constancy of performance (AVCP) of characteristics of combination appliances fired by wood logs and pellets.
This document is not applicable to appliances
-   with boiler intended for water systems having water temperatures above 110°C and 3 bar and for 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,
-   with simultaneous wood and pellet operation with a single flue gas outlet,
-   with non-automatic pellet loading,
-   with single combustion chamber and double flue gas outlet.

4.7.3 Flue gas outlet temperature at part load heat output
The performance of the appliance in relation to flue gas outlet temperature at part load heat output (if
part load is specified) shall be determined in accordance with EN 16510-1:2022, 6.2.1.
The value of the flue gas outlet temperature at part load heat output (if part load is specified) for the
installation of the appliance to a chimney if specified is to be given in [°C] as an integer according to
EN 16510-1:2022, Table 22, no. 48 (T ).

4.7.4 Minimum flue draught at nominal heat output
The performance of the appliance in relation to the minimum flue draught at nominal heat output shall
be determined in accordance with EN 16510-1:2022, 6.5.
The value of the minimum flue draught if specified at nominal heat output for the installation of the
appliance to a chimney is to be given in [Pa] as an integer according to EN 16510-1:2022, Table 22, no.
29 (p ).
nom
Appliances with a nominal heat output less than or equal to 25 kW shall be tested at a flue draught of
(12 ± 2) Pa or at the flue draught specified for the nominal heat output test. The temperature safety test
shall be carried out at the same draught.
Appliances having a nominal heat output greater than 25 kW shall be tested during the nominal heat
output test at such flue draught specified in the appliance instructions.
4.7.5 Minimum flue draught at part load heat output
The performance of the appliance in relation to the minimum flue draught at part load heat output (if part
load is specified) shall be determined in accordance with EN 16510-1:2022, 6.5.
The minimum value of the flue draught if specified at part load heat output (if part load is specified) for
the installation of the appliance to a chimney is to be given in [Pa] as an integer according to
EN 16510-1:2022, Table 22, no. 30 (p ).
part
For the partial load test all appliances shall be tested either at a flue draught of (10 ± 2) Pa or at the flue
draught specified for the part load heat output test.
4.7.6 Flue gas mass flow at nominal heat output
The performance of the appliance in relation to the flue gas mass flow at nominal heat output shall be
determined in accordance with EN 16510-1:2022, 6.12.
The flue gas mass flow value if specified at nominal heat output for the installation of the appliance to a
chimney is to be given in [g/s] with 1 decimal according to EN 16510-1:2022, Table 22, no. 50 (ϕ ).
