4. Installation and Setup
Installation of this gas heater requires professional expertise. Always consult a certified gas technician for installation to ensure compliance with safety standards and local regulations.
4.1 Gas Connection
- The heater is predisposed for Metano (G20) gas with a supply pressure of 20 mbar.
- An alternative gas option is GPL (G30-G31) with a supply pressure of 30-37 mbar. Ensure the correct gas type is used and the appliance is configured accordingly.
- All gas connections must be leak-tested after installation.
4.2 Exhaust System
- The exhaust pipe diameter is 100 mm.
- Ensure the exhaust system is properly installed and sealed to prevent the escape of combustion gases into the living space.
4.3 Placement
- The heater should be placed on a stable, non-combustible surface.
- Maintain adequate clearances from combustible materials as specified by local codes and the installation technician.
- Consider the product dimensions: 900 mm (Width) x 720 mm (Height) x 260 mm (Depth) for appropriate placement.
5. Operation
Follow these steps for safe and efficient operation of your gas heater.
5.1 Starting the Heater
- Ensure the gas supply valve is open.
- Locate the piezoelectric ignition button/lever on the control panel.
- Press and hold the ignition button while simultaneously turning the control knob to the desired setting (e.g., pilot or low flame).
- Observe the pilot burner through the viewing window (if available) to confirm ignition. Continue holding the button for a few seconds after the pilot lights to allow the thermocouple to heat up.
- Release the ignition button. If the pilot light extinguishes, repeat the process.
- Once the pilot is stable, turn the control knob to the desired heat setting.
5.2 Adjusting Heat and Fan
- Adjustable Power: The heater features adjustable power settings. Rotate the control knob to increase or decrease the heat output.
- Room Thermostat: The integrated room thermostat will regulate the heat output to maintain the set temperature, automatically adjusting the flame or turning off the main burner while keeping the pilot lit.
- Fan Operation: The fan assists in circulating warm air. It typically operates automatically when the heater reaches a certain temperature. Some models may offer multiple fan speeds.
- Indicator Light: An indicator light may illuminate to show the heater is operating or in a specific mode.
5.3 Shutting Down the Heater
- To turn off the main burner, rotate the control knob to the 'OFF' position or the pilot setting if you wish to keep the pilot lit.
- For complete shutdown, turn the control knob to 'OFF' and close the main gas supply valve to the appliance.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your gas heater. Always disconnect the gas supply before performing any maintenance.
- Annual Inspection: It is highly recommended to have the heater inspected and serviced annually by a qualified technician.
- Cleaning: Keep the exterior of the heater clean. Use a soft, damp cloth to wipe surfaces. Do not use abrasive cleaners or solvents.
- Air Vents: Ensure all air intake and exhaust vents are free from dust, lint, and obstructions. Use a soft brush or vacuum cleaner to clear them.
- Pilot and Burner: A technician should inspect the pilot burner and main burner for proper flame appearance and cleanliness.
7. Troubleshooting
Before contacting service, review these common issues and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater does not ignite (no pilot flame) | Gas supply off; Piezoelectric igniter faulty; Pilot orifice clogged; Thermocouple issue. | Check gas supply valve; Attempt ignition multiple times; If persistent, contact a qualified technician. |
| Pilot lights but main burner does not ignite | Main burner orifice clogged; Gas pressure too low; Thermostat setting too low. | Ensure thermostat is set above room temperature; Contact a qualified technician. |
| Heater produces unusual odors | New unit burning off manufacturing residues; Dust accumulation; Gas leak. | Ensure good ventilation for new units; Clean heater; If gas odor persists, immediately shut off gas supply and ventilate, then contact emergency services. |
| Fan not operating | Heater not hot enough for fan to activate; Fan motor fault. | Allow heater to reach operating temperature; If still not working, contact service. |
For any issues not resolved by the above steps, or for complex repairs, always contact a qualified service technician.
