Before installation, make sure the maximum permissible length has not been exceeded
by means of a simple calculation:
1. Establish the layout of the system of split flues, including accessories and outlet ter-
minals.
2. Consult table 6 and identify the losses in m
according to the installation position.
3. Check that the sum total of losses is less than or equal to the maximum permissible
length in table 5.

Table. 7 - Typology
Type Description
C2X Intake and exhaust in common flue (intake and exhaust in same flue)
C4X Intake and exhaust in common and separate flues, but undergoing similar wind conditions
C8X Exhaust in single or common flue and wall intake
B3X Intake from installation room by means of concentric duct (that encloses the exhaust) and exhaust in
common flue with natural draught
IMPORTANT- THE ROOM MUST BE PROVIDED WITH APPROPRIATE VENTILATION
C93 Exhaust to a vertical terminal and intake from existing flue.
If the boiler is to be connected DIVACONDENS D PLUS F 24 to a collective flue or to a
single flue with natural draught, the flue or chimney must be expressly designed by pro-
fessionally qualified technical personnel in conformity with the current regulations and be

The unit can operate on natural gas or LPG and is factory-set for use with one of these
7.0
two gases, as clearly shown on the packing and on the data plate. Whenever a gas dif-
ferent from that for which the unit is arranged has to be used, the special conversion kit
will be required, proceeding as follows:
1. Disconnect the boiler power supply and close the gas cock.
2. Replace the nozzles at the main burner, fitting the nozzles specified in the technical
data table in cap. 5, according to the type of gas used
3. Switch the boiler power on and open the gas cock.
4. Modify the parameter for the type of gas:
• put the boiler in standby mode
• press the DHW buttons details 1 and 2 - fig. 1 for 10 seconds: the display shows
"b01" flashing.
• press the DHW buttons details 1 and 2 - fig. 1 to set the parameter 00 (for nat-
ural gas operation) or 01 (for LPG operation).
• press the DHW buttons details 1 and 2 - fig. 1 for 10 seconds.
• the boiler will return to standby mode
5. Adjust the minimum and maximum pressures at the burner (ref. relevant para-
graph), setting the values given in the technical data table for the type of gas used
6. Apply the sticker contained in the conversion kit, near the data plate as proof of the
conversion.
Activation of Auto-setting function for gas valve calibration
THIS PROCEDURE MUST ONLY BE CARRIED OUT IN THE FOLLOWING CASES:
GAS VALVE REPLACEMENT, CARD REPLACEMENT, CONVERSION FOR GAS
CHANGE.
The B&P Gas Valve (with integrated modulating operator) does not provide for mechan-
ical calibration: the minimum and maximum power adjustments are therefore electroni-
cally done via two parameters:
