Sit down on the toilet. Raise the flapper. Do your business. Put the flapper down. Turn the timer on. Leave toilet seat up. The fan will come on and run for about 30 seconds. Then the burner will come on and run for the amount of time set on the timer. This will reduce the human waste to sterile ash that can be vacuumed up when cool. When the time expires and the burner shuts off, the fan will continue to run about 30 minutes to help cool off the combustion chamber. Raising the flapper after the fan shuts off will also help to cool down the combustion chamber. Be careful here. You do not want to use the Usenburn again until it has cooled off sufficiently.
