Either by releasing some of the air it contains or by not applying more heat - as the air cools the balloon descends.
Hot-air balloons function on the principle that warm air rises, and the balloon mechanism holds onto hot air to ascend. Despite this, the hot air can't stay in the balloon forever, the opening at the top of the balloon allowing a slow and steady flow of the hot air out of the balloon and a gentle descent to the ground.
A hot air balloon comes down when less lift is provided by reducing balloon air temperature to control descent.
In rising, a hot air balloon works the same way as a helium balloon : the hot air inside is less dense than the surrounding air outside the balloon. The heavier outside air pushes below the balloon and forces it upward. To come down is easier in a hot air balloon. Unless it is continually reheated, its temperature reverts to that of the surrounding air and the balloon settles back to the Earth under its own weight. Vents that release the heated air (like venting helium in a helium balloon) is an alternative to increase the speed of descent.
A hot air balloon can descend by either releasing hot air from the balloon envelope or by opening a vent at the top of the balloon to allow some of the hot air to escape. This reduces the buoyant force that is keeping the balloon in the air, causing it to descend slowly. The pilot can control the descent rate by carefully managing the release of hot air.
A hot air balloon goes up when the air inside the balloon is heated, causing it to become less dense than the surrounding air. This creates lift. To descend, the air inside the balloon is allowed to cool, increasing its density, which causes the balloon to lower.
Once the air cools, the balloon will lose its lift and settle back to the ground.

If the burner fails or runs out of fuel, the hot air in the balloon (that gives it lift) would cool and the balloon would come down to earth.

The heated air causes the whole balloon to rise. When the air inside the balloon cools down, or when the hot air is let out, the balloon goes down.
bust the balloon
Hot air balloons go down by releasing the hot air in the balloon. Normally you just let the air inside cool and descend slowly. You release hot air only if you wish to descend more quickly.

It's easy, just stop putting hot air in it.
