VENTING
MODELS GD36 AND BGD36 MAY BE VENTED EITHER AS A TOP VENT OR A REAR VENT.REFER TO THE SECTION APPLICABLE TO YOUR INSTALLATION.Use only Wolf Steel or Simpson
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.
Wolf Steel rigid and flexible venting systems must not be combined.Wolf Steel and SimpsonThese vent kits allow for either horizontal or vertical venting of the fireplace. FIGURES 3 & 5. The maximum allowable horizontal run is 20 feet. The maximum allowable vertical vent length is 40 feet. The maximum number of 4" vent connections is two horizontally or three vertically (exclud- ing the fireplace and the air terminal connections) when using aluminum flexible venting.
For optimum flame appearance and fireplace perform- ance, 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.
Purge all gas lines with the glass door of the fireplace open. Assure that a continuous gas flow is at the burner before closing the door.
Under extreme vent configurations, allow several minutes
Six (6") inches is the minimum bend radius allowed for the 7" diameter flexible liner.
For optimum performance it is recommended that all horizontal runs have a 1 inch rise per foot when using Napoleon flexible vent components.
A terminal shall not terminate directly above a sidewalk or paved driveway which is located between two single family dwellings and serves both dwellings. Local codes or regulations may require different clearances. Do not allow the inside liner to bunch up on horizontal or vertical runs and elbows. Keep it pulled tight. A 1¼" air gap all around between the inner liner and outer liner is required for safe operation. Use a firestop when penetrating interior walls, floor or ceiling.
Minimum clearance to combustible construction from fireplace and vent surfaces:sides, back, bottom and top of the unit | 0 inch |
recessed depth | 14 inches |
top, sides and bottom of the vent pipe* | 1 inch |
top of the vent pipe - rear vent only* | 2 inches |
*REAR VENT - A clearance to combustibles of 1" at the bottom of the vent and 2" at the top must be maintained during the first 12" of venting when penetrating combusti- ble walls. The firestop spacer
TOP VENT - Only a clearance to combustibles of 1" all around the vent pipe is required.
