You don’t want those harmful gases leaked into your indoor living spaces.

  4. Sidewall Power Vent – With this venting system, a fan at the end of an exhaust pipe works with the furnace to pull combustion gasses to vent to the outside. This option is also rated higher in safety and energy efficiency than the natural vent system.
