Safety Precautions
- Turn off the gas supply: Locate the gas shut-off valve near the heater and turn it clockwise to shut off the gas.
- Ventilate the area: Open windows and doors to ventilate the room and prevent gas buildup.
- Wear appropriate clothing: Wear gloves and safety glasses for protection.
- Inspect the heater: Check for any leaks or damage before attempting to disconnect it.
Tools and Materials
- Adjustable wrench
- Screwdriver
- Pipe wrench (optional)
- Teflon tape (optional)
Step-by-Step Instructions
1. Shut Off the Gas Supply
Locate the gas shut-off valve near the heater. It’s usually a yellow-handled lever or a valve with a “gas” label. Turn the valve clockwise until it’s fully closed.
2. Disconnect the Gas Line
Using an adjustable wrench, loosen the nut that connects the gas line to the heater. Grip the gas line firmly with a pipe wrench (if necessary) and pull it away from the heater.
3. Remove the Heater from the Wall
Unscrew the screws or bolts that secure the heater to the wall. Carefully lift the heater off the wall and set it aside.
4. Cap the Gas Line
Apply Teflon tape to the threads of the gas line where the heater was connected. Screw a gas line cap onto the line to prevent gas leaks.
5. Seal the Wall Opening
If there’s an opening in the wall where the heater was installed, seal it with a non-combustible material such as fire-rated caulk or a metal plate.
6. Check for Leaks
Turn on the gas supply and use a soapy water solution to check for leaks. Apply the solution to the gas line, cap, and any other connections. If bubbles form, there’s a leak that needs to be repaired.
7. Test the Heater (Optional)
If you’re replacing the heater, you can test the new one by following the manufacturer’s instructions. Ensure that it’s properly connected and functioning safely.
Troubleshooting
- Gas leak: If you detect a gas leak, shut off the gas supply immediately and call a qualified gas technician.
- Loose connections: Ensure that all connections are tight and properly sealed.
- Damaged heater: If the heater is damaged, do not attempt to disconnect it. Call a professional for assistance.
