VENTING LENGTHS AND AIR TERMINAL LOCATIONS CONTINUED
When using Wolf Steel venting components, use only approved Wolf Steel rigid / flexible components with the following termination kits:Wall Terminal Kit GD222, or 1/12 to 7/12 Pitch Roof Terminal Kit GD110, 8/12 to 12/12 Roof Terminal Kit GD111, Flat Roof Terminal Kit GD112 or Periscope Kit GD201 (for wall penetration below grade). With flexible venting, in conjunction with the various terminations, use either the 5 foot Vent Kit GD220 or the 10 foot Vent Kit GD330.
The maximum allowable vertical vent length is 35 feet, the minimum is 3 feet.
For optimum flame appearance and fireplace performance, keep the vent length and number of elbows to a minimum. The air terminal must remain unobstructed at all times. Examine the air terminal at least once a year to verify that it is unobstructed and undamaged.
Horizontal runs may have a 0" rise per foot in all cases using Wolf Steel or Simpson
For optimum performance, it is recommended that horizontal runs have a minimum 1" rise per foot when using any of these vent systems.

VENT INSTALLATIONS
For safe and proper operation of the fireplace follow the venting instruction exactly.
Deviation from the minimum or the maximum vertical vent length can create difficulty in burner
Under extreme vent configurations, allow several minutes
Vent lengths that pass through unheated spaces (attics, garages, crawl spaces) should be insulated with the insulation wrapped in a protective sleeve to minimize condensation.
Provide a means for visually checking the vent connection to the fireplace after the fireplace is installed. Use a firestop, vent pipe shield or attic insulation shield when penetrating interior walls, floor or ceiling.
HORIZONTAL VENT SECTIONS
A minimum clearance of 1" at the bottom and sides and 2" at the top of the vent pipe in all horizontal runs to combustibles is required. Use firestop spacer
VERTICAL VENT SECTIONS
A minimum of 1" all around the vent pipe on all vertical runs to combustibles is required except for clearances in fireplace enclosures. See "Minimum Enclosure Clearances" section. Use firestop spacer
