How to Blow down.

To Blow down the boiler insert the blow down key into the cage on the blow down valve, making sure that the protrusion on the blow down key fits into the recess of the cage on the blow down valve. Now turn the blow down key anti-clock wise slowly until the valve is fully open. Hold this position for approximately 6 to 10 seconds and then close the blow down valve by turning the blow down key in an clockwise direction until the key cannot turn any further ( Do not force the blow down key.) Once the blow down valve is closed remove the blow down key from the valve cage and place on the floor by the blow down valve.
Always remove the blow down key from the blow down valve as this will indicate that the valve is closed, as the blow down key can only be removed from the blow down valve when the valve is closed.
