It is fine to go through a roof with the L&L Vent-Sure kiln fumes vent system.
- So long as you keep the fan motor within 60 feet of the kiln, and minimise 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.
- Air temperature in the duct is less thean 150F.
- Remember this is a vent just for the corrosive fumes that come out of clay and glazes when they are fired. This vent system will do nothing to exhaust heat. If this is a small room you will need additional exhaust venting for the heat.
