•
Chart is for one 90° bend, with 1/4” vertical raise minimum per foot of horizontal length.
•
For each additional 90° or two 45°, add 1ft of vertical height.
•
Maximum two 90º bends, or equivalent.
•
Minimum 2 ft straight length between bends.
Maintain a minimum of 1” clearance to combustibles on sides and bottom and 2” from top surface
of the vent.
The gas fireplace is designed and optimized for majority of the installations with short vents. With
taller vents the efficiency and flame characteristics will change. Therefore, an exhaust restrictor
plate is provided by the manufacturer to preserve as much of the original short vent performances as
possible on taller vent configurations.
NOTE: Maximum vent lengths subject to local codes.

nents.
•
Maximum vertical height of 25 feet.
•
Vertical height of the vent system must have at least 3 ft or more per 90
0
elbow in the vent system.
•
Vertical height of the vent system must also be increased 1 ft for every 2 ft of horizontal length
added to the vent system.
Example: A vertical venting system with a 90
0
elbow, a horizontal offset of 4 ft and another 90
0
elbow.
Vertical height of the vent system must be 3ft + 2ft + 3ft = 8ft or higher to a maximum of 25 ft.
Vertical Venting between 10 ft and maximum 25 ft requires restrictor plate #2
