5.8 Connecting the cooling tube to the flame inspection window (Fig. 9)
The flame inspection window is equipped with a pressure fitting (1). Once the interior screw is loosened, it must be connected to outlet 2 on
the burner using a silicone hose or copper pipe. This allows the air blown back by the fan to cool the glass on the window and prevent it from
turning black. Failure to connect the hose or pipe to the window can cause the glass to break.
When disassembling the window for cleaning, check the condition of the seals, replacing them if necessary. After closing, verify tightness.
6. CONTROL PANEL (OPTIONAL)
C16015180 – LV thermostatic control panel, 2 stages
C16015190 – LV thermostatic control panel, 3 stages
C16015150 – EBM (Efficient Boiler Management) control panel
6.1 LV thermostatic control panel, 2 and 3 burner stages (Fig. 11)
(The diagrams shown below are valid for all three panels.)
The panel is not supplied. It's made of plastic with protection index IP40, and houses adjustment and safety instruments. The LV panels include
a thermostat signal to control the anti-condensation pump, as described in paragraph 5.5.5. The electrical system for the boiler must be:
- designed and installed by qualified personnel and connected to a grounding system in accordance with current legal standards.
- suitable for the maximum power absorbed by the boiler, using electrical cables with the appropriate cross-section.
The ground wire in the power cables and cables connecting to the boiler must be several mm longer than the other wires in the same cable.
For connections between the burner, electrical panel and electrical power supply, the use of H07 RN-F cables is recommended for visible con-
nections. For other types of systems, or for special environmental situations, consult current standards. The composition and diameter of the
wires is calculated based on the power absorbed by the burner. To access the instruments, rotate the front panel (A). To access the connection
terminals and unwind the capillary tubes from the thermostats and thermometer, remove the top panel (B) after first removing the 2 side screws
(C). The control thermostats (12-13 - Fig. 12) can be set by the user, using the knob at the front. The safety thermostat has a fixed setting and
manual reset. The following are compulsory:
- use a two-pole, thermal-magnetic overload switch, mains disconnecting switch, in accordance with CEI-EN standards (minimum contact
opening of 3 mm)
- respect the connection L1 (Phase) - N (Neutral)
- use cables with a cross-section greater than or equal to 1.5 mm2, including terminals
- refer to the wiring diagrams in this instructions manual for any operations on the electrical system
- effectively ground the appliance
- it is forbidden to use water hoses to ground the appliance.
The manufacturer is not liable for any damage caused by the failure to ground the appliance, or for non-compliance with the wiring diagrams.
