5.21 STOVE CALIBRATION AND DEPRESSION MEASUREMENT
This stove has a pickup point positioned on the tank in order to measure the depression of the combustion chamber and verify its
proper operation.
To do this, proceed as follows:
• Unscrew nut “D” on the rear of the stove and connect a digital pressure switch with a tube to detect the negative pressure (see
Fig. 89
or
Fig. 90
).
• Load the feed screw via appropriate function.
• Start the stove and set "Set_Flame" to power 1 (the start-up time of this stove lasts between 8 and 10 minutes to ensure
minimum draught).
• Compare the read values with those on the table.
• Change power every 10 minutes and wait for it to stabilise.
• Access the user menu and, if necessary, change the parameters.
