PERISCOPE TERMINATION
Use the GD201 periscope kit to locate the air termination
above the 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 the grade. The
maximum allowable vent length depends on the model
of fireplace, as illustrated.
