Bleeding a gas geyser, also known as purging the gas line, is a process of removing air from the gas line to ensure proper gas flow and ignition. Here’s a general guide on how to bleed a gas geyser:
- Turn Off Gas Supply: Before starting any work, ensure that the gas supply to the geyser is turned off. You can usually find the gas shut-off valve near the gas meter or at the gas line leading to the geyser.
- Allow Ventilation: Make sure the area around the gas geyser is well-ventilated to prevent the accumulation of gas fumes.
- Locate the Gas Line: Identify the gas line that connects to the gas geyser. This line usually runs from a gas valve or regulator to the geyser.
- Find the Bleed Valve: Many gas geysers have a bleed valve near the gas inlet. The bleed valve is typically a small screw or knob that you can turn to release trapped air from the gas line.
- Open a Hot Water Faucet: To help purge the air from the gas line, open a hot water faucet in the house connected to the geyser. This will create a demand for hot water and help draw gas through the system.
- Turn On Gas Supply: Turn on the gas supply to the geyser. If you turned off the main gas supply, you’ll need to turn it back on now.
- Bleed the Gas Line: Slowly open the bleed valve on the gas geyser. You may hear a hissing sound as air escapes from the gas line. Keep the valve open until you smell gas coming out steadily without any air pockets.
- Close the Bleed Valve: Once you’ve purged the air from the gas line and smell only gas, close the bleed valve tightly to prevent gas leaks.
- Check for Leaks: After bleeding the gas line, check all connections for gas leaks. You can use a gas leak detector solution or soapy water to detect leaks. If you find any leaks, tighten the connections or replace any faulty components.
- Test the Geyser: Turn on the geyser and test it to ensure it ignites properly and functions as expected. If the geyser doesn’t ignite or there are any issues, turn off the gas supply and consult a qualified technician for further inspection and repairs.
It’s important to follow safety precautions when working with gas appliances. If you’re unsure about how to bleed a gas geyser or if you encounter any issues, it’s best to seek assistance from a qualified technician or plumber.
