Remarks
The certification tests were accomplished in accordance with the manufacturers written test instruction for
the lab (please find enclosed in annex 11), the ASTM E3035-17 Cordwood test standard, the EPA ALT125
letter and the ASTM E2515-11 dilution tunnel and sampling standard.
Start-up operation
The Morsø 2B Standard 2020 stove has a traditional air control system with a rotary type dial on the
loading door to the front. For start-up operation, the air valve is kept fully open (3 and one quarter of a
revolution), which position is maintained throughout the high fire tests. For the low fire test, after ignition
the air valve is throttled to 3 quarters of a revolution open, and for the medium fire test, after ignition the
air valve is throttled to 1 and one quarter of a revolution open.
Please find a detailed description of the start-up procedure in the manufacturers test instruction for testing
procedure (annex 11)
Sampling arrangement
The PM specimen is extracted from the Ø150 mm Full Flow Dilution Tunnel by means of a dual probe and
filter holder system as specified by ASTM E2515-11, clause 6.1.1.1. The filter holders are of type 47 mm
Pall 1235. There are 3 sets of backed-up filter holders for PM sampling and one single filter holder for the
room blanc measurement. The PM sampling line filter holder arrangements have thermostatic support to
maintain the filter temperatures in between 26,7-32,2 degrees C, respectively 80-90 degrees F.
