PERISCOPE TERMINATION

For optimum performance, it is recommended that all hori-

zontal runs have a 1 inch rise per foot.

When terminating vertically, the vertical rise is a minimum 36 inches
and a maximum 40 feet from the centre of the fi replace fl ue outlet.
Use the GD201 periscope kit to locate the air termination
above grade. The periscope must be installed so that when
fi nal grading is completed, the bottom air slot is located a mini-
mum of 12 inches above grade. The maximum allowable vent
length depends on the model of fi replace, as illustrated.
