You have the option to install the Vent Master as a positive or negative pressure system, meaning that you can install the Vent Master to push the vent exhaust (positive pressure) out of the room or you can install the Vent Master to pull the vent exhaust (negative pressure) out of the room.

For a Negative Pressure System : Sufficient length of high temperature 2” vacuum hose to allow blower assembly to be mounted adjacent to exhaust opening in wall.
Orton VentMaster® (with downdraft ventilation)
With Downdraft Venting, the kiln
is kept under a slight negative pressure. Gases are pulled out of the
kiln near the bottom, mixed with fresh room air and exhausted to the
outside through a duct. Improved air flow in the kiln results in more
uniform temperatures, reducing hot and cold spots.
Kilns cool faster when properly vented. In some cases, the kiln can
cool down up to four hours faster, meaning you can empty and refill the
kiln in less time.
Downdraft venting can also extend the life of the metallic parts of
your kiln by removing corrosive fumes. This means longer kiln life and
reduced repair costs.
