Dryer Hoses are something that most people don't pay attention to, but how they are routed is important for fire safety and other reasons.

When venting a dryer, remember which direction warm air wants to go to - up. So try to keep a relatively good pitch upward without having sags or swoops in it. 

Also, try not to make the run of duct too long, otherwise the vapors cool and collect in puddles in the vent hose.
