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.

    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.
