• Install rock-wall cloth rated to handle tempera-
tures up to 270°C to insulate the exhaust tubing
passing through ceiling ducts.
• Do not use exhaust tubing less than 3 inches in
diameter.
• Do not use galvanized tin tubing or double wall
tin tubing.
• Do not connect the NCAT exhaust port directly
to an external fan with a rating of more than 60
CFM. This will create a negative airflow in the
exhaust system. The blower motor in the
NCAT is rated at 65CFM and will provide
enough power for emission up to approximately
10 feet.
