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 model of fireplace, as
illustrated.
When venting, the horizontal run must be kept to a mini-
mum of 10 inches or a maximum of 20 feet. If a 20 foot
horizontal run is required, the fireplace must have a mini-
mum vertical rise immediately off the fireplace of 57 inches.
