Maintenance and Safety Tips

• Routine Inspection: Perform a comprehensive check of all components at least twice a year.
• Professional Servicing 🧑‍🔧: Engage certified technicians for annual servicing, especially for complex parts like the burner and heat exchanger.
• System Flushing: Once or twice a year, flush the system to remove any sediment or rust inside the boiler. This is crucial for maintaining efficiency.
• Leak Checks 🚰: Regularly inspect all joints and pipes for leaks. Even small drips can signify larger issues.
• Noise Monitoring: Be aware of unusual sounds, such as banging or hissing, as they may indicate air trapped in the system or other issues.
• Carbon Monoxide Detector: Always have a detector installed near your boiler to alert you of any dangerous emissions.

Troubleshooting Common Issues

1. Boiler Not Heating

• Possible Causes: Thermostat is off, an issue with the gas supply, or pilot light extinguished.
• Actions: Check the thermostat setting, ensure the gas supply is uninterrupted, and relight the pilot if needed.

2. Noisy Boiler

• Possible Causes: Build-up of sediment in the heat exchanger or air trapped in pipes.
• Actions: Flush the system to remove sediment and bleed the radiators to release trapped air.

3. Water Leaks

• Possible Causes: Pressure too high causing the relief valve to discharge, or corrosion in the pipes.
• Actions: Inspect the pressure gauge, adjust if necessary, and call a technician if corrosion is detected.

4. Low Pressure

• Possible Causes: System leaks or malfunctioning expansion tank.
• Actions: Repressurize the system and inspect for leaks in the boiler and connected piping.

5. Boiler Turns Off Unexpectedly

• Possible Causes: Overheating, low water levels, or faulty thermostat.
• Actions: Check water levels, adjust thermostat settings, and monitor for overheating signs.
