When the Nova Florida VELA COMPACT flashes red for 3 seconds and then shows two green lights when switching to heating, it indicates a normal transition during startup. The red flashing likely signals initial system checks or ignition, and the two green lights show that the boiler is operating in heating mode with a flame present.

1.2 Operating the Boiler 1.2.1 Switching On The following procedures are to be implemented only after the boiler is installed, tested and its installation is certified by a qualified fitter. • Open the gas stop cock. • connect power mains to the boiler (no. 2 LED turns on displaying the green color); •...
1.3. Boiler shut-down When any malfunction occurs, the boiler automatically shuts down. Refer to no. 1 chart (on page 6) in order to detect the boiler operation status. In order to identify plausible malfunction origin, see no. 6 paragraph “Troubleshooting” at the end of the manual. In relation to the type of malfunction, proceed as described hereafter.
1.4. Maintenance Have routine boiler maintenance performed according to the schedule indicated in the relevant section of this manual. Appropriate boiler maintenance ensures efficient operation, environment preservation, and safety for people, animals and objects. Only qualified personnel are to service the boiler. The manufacturer recommends Customers to contact authorized Service Centers for maintenance and repairs, they are best qualified for that procedure.
2. Technical Characteristics and Dimensions 2.1. Technical Characteristics The boiler is equipped with an integrated gas atmospheric burner and the following versions are available: - CTN 24 AF: open chamber, natural draught boiler with electronic ignition and instantaneous DHW supply; - CTFS 24 AF: sealed chamber, forced draught boiler with electronic ignition and instantaneous DHW supply;...

3. INSTRUCTIONS FOR THE INSTALLER 3.1 INSTALLATION STANDARDS The boiler is designed as II2H3+ category and is to be installed in compliance with laws and standards in force in the country of instal- lation. 3.2. Installation Installation and maintenance procedures are to be implemented employing exclusively accessories and spare parts which are approved and supplied by the manufacturer.
3.2.3. Positioning the Boiler Each unit is supplied along with a paper template, in the package, allowing positioning the pipes connec- ting CH system, DHW system, gas supply, and air intake/flue gas discharge ducts to the boiler before installing the boiler itself. The template is made of highly resistant paper and is to be affixed to the wall on which the boiler is to be mounted using a carpenter’s level.
3.2.4. Installing the Boiler Before connecting the boiler to the CH and DHW pipe systems, clean the pipes carefully and eliminate any metal left during manufacturing and welding process, any oil or grease that may be left and that could damage the boiler or alter its operation if it reaches the boiler.
Direct emission into the atmosphere Natural draught boilers can discharge flue gas directly into the atmosphere via a duct which goes through the outside walls of the buil- ding and ends with an anti-wind gust device terminal. The flue gas exhaust duct is to comply with the following requirements: - its sub-horizontal part inside the building must be as short as possible (not longer than 1,000 mm);...
3.2.6.2. Forced draught boiler 3.2.6.2.1 Configuration of air intake and flue gas discharge ducts Type Type B22 This boiler is conceived for connection Type to an existing flue system either internal or external to the boiler room. Combustion air is taken directly from the boiler room itself while flue gas is conveyed to the outside.
3.2.6.2.2. Air intake and flue gas discharge system via 100/60 mm coaxial pipes Type C12 Minimum permissible length of horizontal coaxial pipes is 1 meter, not counting the very first elbow connected to the boiler. Maximum permissible length of horizontal coaxial pipes is 4 meter, not counting the first elbow connected to the boiler. For each additional elbow maximum permissible length must be reduced by 1 meter.
3.2.6.2.3 Air intake and flue gas discharge system via 80/80 mm split pipes C42 – C52 – C82 installation category Air intake Minimum permissible length of air intake pipe is 1 meter. Each wide radius 90° elbow (R=D) equals a 1 meter long pipe section. Each narrow radius 90°...
Example no. 2 Example no. 1 162 mm H min. = 150 mm 500 mm Pic. 14 – Split pipe installation samples Pic. 15 - Additional split pipe installation samples 3.2.7 Checking combustion efficiency In order to check combustion efficiency, turn no. 5 knob fully clockwise and completely open one or two domestic hot water taps so that the boiler will operate at max.
3.2.8. Gas mains connection Cross-section of gas supply pipe must be equal or greater than the boiler one. Cross-section size depends on its length, layout pat- tern, gas flow rate. It is therefore to be sized accordingly. Comply with installation standards enforced in the installation country. They are considered as an integral part of this booklet. Remember that before operate an internal gas distribution system and before connecting it to a meter, it must be checked for leaks.
3.2.10. Power mains connections The boiler is supplied with a three-poled power cable, already connected to the electronic board and it is provided with an anti-ruptu- re firming clamp. The boiler is to be connected to a 230V-50Hz electric power supply. Comply with phase / neutral polarity sequence when power connecting the boiler.
3.4 Starting the Boiler 3.4.1 Preliminary Checks Before starting the boiler it is necessary to perform the following checks: - flue gas discharge pipe and its terminal are installed in accordance to the instructions: when the boiler is running no products generated by combustion are to leak from any gasket;...
3.6 Adaptation to other gas types and burner adjustment The boilers are manufactured for the gas specified upon order. After sale transformation is to be exclusively implemented by qualified personnel, employing manufacturer designed accessories and following the procedure and adjustment instructions for an accurate boiler setting-up. Adapting the boiler from METHANE to LPG - Remove the main burner;...
B) Minimum heat output adjustment - Disconnect electric wiring from D modulation coil (pic. 20); - turn the burner on and check minimum pressure value according to no. 2 and no. 3 charts on page 14; - in order to adjust pressure, hold nut B still by means of a 100 mm tool, and turn plastic screw C CLOCKWISE to increase and COUNTER-CLOCKWISE to decrease gas pressure;...
5. MAINTENANCE Routine boiler maintenance is to be scheduled according to current laws and regulations. Appropriate boiler maintenance ensures efficient operation, environment preservation, and safety for people, animals and objects. All maintenance and repair procedures are to be carried out by qualified personnel. The manufacturer recommends Customers to contact an authorized Service Centre for all maintenance and repair procedure as they are best trained for the purpose.
