PERISCOPE TERMINATION
Use the GD401 periscope kit to locate the air termination
above grade. The periscope must be installed so that when
final grading is completed, the bottom air slot is located a
minimum of 12 inches above grade. The maximum allow-
able vent length depends on the fireplace, as illustrated.
