The Laser Auto-Center System is ideal for installing a new chimney venting system such as a Class A chimney pipe, Pellet Vent pipe or Direct Vent gas pipe. The Laser Auto-Center System utilizes a low power class III A laser beam to indicate the center mark for the vent pipe to pass through a ceiling or wall. Simply place the laser on the stove outlet or the chimney pipe and instantly know where the center point is on a ceiling or wall. The accuracy of this system has been tested to be +/- 1/4". The laser system can be used with 4", 6" and 8" pipe. Adapters are included for 6" and 8" pipe sizes. This device is extremely helpful when you need to pass through more than one level of the home. If you are tired of the hassles of dealing with a plumb bob to find the center line, the Laser Auto-Center System is for you.

Helpful Tips: It is very important that the appliance and the outlet of the appliance is level before you use the Laser Auto-Center System. Make sure to check that both axis of the appliance are level before you use the device.

Important Notes: For vertical use, rotate the device/outlet adaptor so the bottom edge of the warning label applied to the device is parallel with the face of the appliance. For horizontal use make sure the warning label on the device is parallel with the floor.

Warning: This laser beam can cause eye damage if it is viewed directly in an eye. Do not shine this beam into your eyes or in the eyes of others.
