1. Product Overview
The Gedsffati HD08-G is a combined carbon monoxide (CO) and combustible gas detector designed for home use. It continuously monitors the levels of CO and various combustible gases, including natural gas, liquefied petroleum gas (LPG), methane, ethane, propane, and butane. This device features high-precision sensors, a 2.1-inch high-resolution colorful LCD screen for real-time display of measurements, and audible and visual alarms.
Key features include:
- Combined Detection: Monitors both carbon monoxide and combustible gases simultaneously.
- High Performance Sensors: Utilizes electrochemical reaction and semiconductor electrical resistance variation principles for quick and accurate detection, with an approximate 5-year lifespan.
- Real-time Monitoring: Sensors operate every 2 seconds for frequent and rapid detection.
- Multifunctional Display: Includes air temperature and humidity sensors, displaying these measurements on the screen.
- Clear LCD Screen: A 2.1-inch colorful LCD screen provides visible and easy-to-read values.
- Safety Compliance: Complies with EU safety regulations EN 50291 (Carbon Monoxide) and EN 50194 (Combustible Gas Detectors).

2. Setup and Installation
The Gedsffati HD08-G detector is designed for direct insertion into a standard home power outlet, offering a plug-and-play setup. No complex wiring or battery installation is required.
2.1 Placement Considerations
- Install the detector in areas where gas appliances are present, such as kitchens, utility rooms, or near heating systems.
- Ensure the detector is not obstructed by furniture, curtains, or other objects that could block air circulation.
- Avoid placing the detector in direct sunlight, near vents, fans, or in excessively dusty or humid environments.
- For optimal CO detection, place the unit at a height where CO is most likely to accumulate, typically at breathing level. For combustible gases, place it closer to the floor if the gas is heavier than air (e.g., LPG, propane, butane) or closer to the ceiling if lighter than air (e.g., natural gas, methane).
2.2 Initial Power-On
- Plug the device directly into a standard AC 100-240V/50-60Hz power outlet.
- The device will automatically power on and begin its self-test sequence.
- Once the self-test is complete, the screen will display current CO levels, gas concentration indicators, temperature, and humidity. The carbon monoxide icon will be green if CO levels are 0-50ppm, indicating normal operation.

3. Operating Instructions
The HD08-G detector features three control buttons (H, O, D) for various functions and a clear LCD display for information.
3.1 Button Functions
- Button H: Short press this button to change the brightness of the screen.
- Button O:
- Short press to allow the device to perform a self-test.
- Long press to change the temperature unit between Celsius (℃) and Fahrenheit (℉).
- Button D: Short press this button to turn the buzzer (audible alarm) on or off.

3.2 Alarm Function Introduction
The device provides distinct visual and audible alarms based on the detected concentration levels of carbon monoxide and combustible gases.
3.2.1 Carbon Monoxide (CO) Alarm
- 0-50ppm: No alarm. The carbon monoxide icon on the screen is green.
- 51-200ppm: The device beeps every 3 minutes. The carbon monoxide icon turns yellow and flashes.
- 201-999ppm: The device emits a continuous beep. The carbon monoxide icon turns red and flashes.
3.2.2 Combustible Gases Alarm
- No Combustible Gas: No audible alarm. The green gas icon flashes.
- Low Concentration: The device beeps every 3 minutes. The yellow gas icon flashes.
- Medium Concentration: The device beeps every 3 minutes. The orange gas icon flashes.
- High Concentration: The device emits a continuous audible alarm. The red gas icon flashes.

4. Maintenance
To ensure the optimal performance and longevity of your Gedsffati HD08-G detector, follow these maintenance guidelines:
- Regular Cleaning: Gently wipe the exterior of the detector with a soft, damp cloth. Do not use harsh chemicals, abrasive cleaners, or solvents.
- Avoid Obstructions: Ensure that the air vents on the device are not blocked by dust, debris, or other objects. The 3D porous air duct design relies on clear airflow for accurate detection.
- Self-Test: Perform a self-test regularly (e.g., monthly) by short pressing the 'O' button to confirm the device is functioning correctly.
- Sensor Lifespan: The sensors have an approximate lifespan of 5 years. While the device is designed for long-term use, consider replacing it after this period to ensure continued accuracy and reliability.

5. Troubleshooting
This section addresses common issues and their solutions. If you encounter a problem not listed here, please refer to the contact information for support.
5.1 Indicator Lights and Alarms
- Green Light (screen off and indicator light on): Indicates normal operation and gas concentration monitoring.
- Red Light (alarm): Indicates a mute error or sensor malfunction. If this occurs, perform a self-test. If the issue persists, contact customer support.

5.2 Incorrect Temperature Unit Display
Issue: The temperature unit is not displaying in your preferred Celsius (℃) or Fahrenheit (℉).
Solution: Long press the 'O' button to toggle between Celsius and Fahrenheit. Note: An error in some printed user manuals incorrectly states to use the 'D' button for this function. Please use the 'O' button.
5.3 False Alarms
If the detector triggers an alarm without an apparent gas leak or CO presence:
- Ventilate the Area: Open windows and doors to air out the space.
- Check for Interfering Substances: Strong cleaning agents, aerosols, or high humidity can sometimes trigger false alarms.
- Relocate the Detector: If false alarms persist, try moving the detector to a different location, away from potential sources of interference.
- Perform Self-Test: Use the 'O' button to perform a self-test. If the device indicates a malfunction, contact support.
