6.21 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:
• Connect a digital pressure switch with a tube to detect the negative pressure (see
).
• 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 mini-
mum 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.

SPECIAL MAINTENANCE
7.1
INTRODUCTION
For a long working life of the stove, have a periodic cleaning of the stove as described in the following paragrafs.
• Fume outlet pipes (fume c chimney flue + chimney pot) must always be cleaned, scrubbed and checked by an autho-
rized technician in compliance with local regulations, with the instructions of the manufacturer and those of your insurance
company.
• If there are no local regulations and no instruction from your insurance company, it is necessary to have your fume pipe, chim-
ney flue and chimney pot cleaned at least once a year.
• It is also necessary to have the combustion chamber, motors and fans cleaned and to have the gaskets and the electronical
elements checked at least once a year.
All these operations must be planned in time with your Autorized Technical Assistance Service.
• After a long ineffective time, before turning on the stove check if there are obstructions in the fume exhaust.
• If the stove had been using continuously and intensely, the whole system (chimney included), must be cleaned and checked
more frequently.
