For optimum performance, it is recommended that all horizontal 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 fireplace flue outlet.

*When using rigid venting, this minimum vertical length may be reduced to 8½".

PERISCOPE TERMINATIONCORNER TERMINATION

Use the GD201 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 allowable vent length depends on the model of fireplace, as illustrated.

FIGURES 4

MODELS GD36: The maximum vent length for a corner installation is 24 inches, where only 6 inches of vertical rise is used. All corner installations require a minimum 6 inch rise. See FIGURE 5A.

MODELS BGD36: The maximum vent length for a corner installation is 20 inches of horizontal run, in addition to the 45° offset. In this case zero rise is acceptable when using rigid. Flexible venting must maintain a 6" rise. See FIGURE 5B.
