    Boiler Safety Preparations for Replacement

    Safety is paramount when working on your boiler. Begin by turning off the power supply and shutting off the water supply to the boiler. Allow the system to cool completely before proceeding. This step prevents burns and ensures a safe working environment.

    • Turn off power at the circuit breaker

    • Shut off the water supply valve

    Old Air Vent Valve Removal Process

    Once the boiler is prepared, you can begin the removal process. Start by placing a bucket beneath the valve to catch any residual water. Use the adjustable wrench to loosen and remove the old valve. Be cautious of any remaining water that may spill out.

    1. Position bucket under the valve

    2. Loosen valve using adjustable wrench

    3. Remove valve and allow water to drain

    Install the New Air Vent Valve

    With the old valve removed, it’s time to install the new one. Apply Teflon tape to the threads of the new valve to ensure a tight seal. Screw the new valve into place using the adjustable wrench. Ensure it is snug but do not overtighten, as this may damage the valve.

    1. Apply Teflon tape to new valve threads

    2. Screw in new valve by hand

    3. Tighten gently with adjustable wrench

    Test for Leaks After Replacement

    After installation, it is crucial to test for leaks. Turn the water supply back on and check the new valve for any signs of leakage. If leaks are present, tighten the valve slightly more. Ensure the system is functioning properly before restoring power.

    • Turn water supply back on

    • Check for leaks around the valve

    • Tighten if necessary
