It is fine to go through a roof with the L&L Vent-Sure kiln fumes vent system.
- Keep the fan motor within 60 feet of the kiln, and minimize the number of elbows, it will be fine.
- You may need to hardwire the fan motor as the power cord it comes with has an in-line on/ off switch.
- The air temperature in the duct is less than 150F.
- Remember this is a vent just for the corrosive fumes that come out of clay and glazes when they are fired.
- This venting system will do nothing to exhaust heat.
- If this is a small room you will need additional exhaust venting for the heat.
