Warning
Coaxial flue pipes must not under any circumstances be
used for flue gas exhaust and burner air suction on these
units: functioning may be irreparably compromised.
4.8. FIRST START-UP AND COMBUSTION ADJUSTMENT
Warning
The first start-up should always be carried out by a
specialised technician checking the correctness of the
combustion parameters.
Warning
The burner settings are pre-set at the factory and may not
comply with those required, therefore, the settings need to
be checked and, where necessary, corrected.
The adjustment values (burner diesel pressure, combustion head
position, air adjustment) for each of the burners approved for these
A) Minimum 1 m
B) As short as possible

D) Chimney draught H shape

units are indicated in the "TECHNICAL CHARACTERISTICS TABLE".
The probe used to periodically check combustion and flue smoke
temperatures is to be inserted as indicated:
Combustion is clean and stable when combustion values are as
follows:
Bacharach index: 0 (white)
CO : 11 ÷ 12,5 %
2
Oxygen (O
CO
max
You may have to change the burner settings due to the fuel used
and/or installation conditions (high altitude, air suction pipe with or
without Snorkel, etc.) if combustion parameters are not correct.
When inspection tests are completed, the hole drilled for the probe
must be sealed with a material that is resistant to high
temperatures and that ensures the tube remains airtight.
Warning
Upon completing the aforementioned operations, the
declaration
penultimate page of this manual is to be completed in full
and signed.
5. OPERATING INSTRUCTIONS
5.1. START
To start the heater:
• Raise panel (n) on the electrical panel box;
• Make sure the switch (a) is set to "0";
• Supply electrical power to the space heater by pulling up the
disconnecting switch on the electric power panel: the green lamp
(b) will light up indicating that power is being supplied to the
panel;
•Turn switch (a) to position H or H+V: the burner will begin the start-
up and pre-wash cycle, after which the flame will ignite; after the
combustion chamber has been heating for a few minutes, the
main fan will start up;
Warning
The fan runs continuously in H+V mode, even when the
desired room temperature has been reached, and the
burner turns off.
Warning
In H mode, the fan only runs when the combustion
chamber is sufficiently hot. Therefore, when the desired
room temperature has been reached, the burner turns off
and the fan keeps running only until the combustion
chamber has cooled completely.
• If the heater does not work during the start cycle or work cycle,
consult "TROUBLESHOOTING" to find the cause of the
malfunction.
Warning
If the burner goes into safety stop (lamp m) push reset
button (d) for 3 seconds to restart the heater.
