VENTING
VENTING LENGTHS
Use only Wolf Steel, Simpson
Temp or American Metal Amerivent venting components.
Minimum and maximum vent lengths, for both horizontal and vertical installations, and air terminal locations for ei- ther system are set out in this manual and must be ad-
hered to. For Simpson
All outer pipe joints of these venting systems must be sealed using Red RTV Hight Temperature Sealant.
Wolf Steel, Simpson
A starter adaptor must be used and may be purchased from the corresponding supplier:

For vent systems that provide seals on the inner exhaust flue, only the outer air intake joints must be sealed using a red high temperature silicone (RTV). This same sealant maybe used on both the inner exhaust and outer intake vent pipe joints of all other approved vent systems except for the exhaust vent pipe connection to the fireplace flue collar which must be sealed using the black high tempera- ture sealant Mill Pac.
When using Wolf Steel venting components, use only ap- proved Wolf Steel rigid / flexible components with the fol- lowing termination kits: WALL TERMINAL KIT GD422, or 1/12 TO 7/12 PITCH ROOF TERMINAL KIT GD410, 8/12 TO 12/12 ROOF TERMINAL KIT GD411, FLAT ROOF TERMI- NAL KIT GD412 or PERISCOPE KIT GD401 (for wall pen- etration below grade). With flexible venting, in conjunction with the various terminations, use either the 5 foot vent kit GD420 or the 10 foot vent kit GD430.
These 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 5" 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 removed. Assure that a continuous gas flow is at the burner before
Under extreme vent configurations, allow several minutes
Eight (8") inches is the minimum bend radius allowed for the 8" 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 sin- gle 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 pen- etrating interior walls, floor or ceiling.
Minimum clearance to combustible con- struction from fireplace and vent sur- faces:
sides, back, bottom and top of the unit | 0 inch |
recessed depth | 22 inches |
top, sides and bottom of the vent pipe | 1 inch |
vent heat shield | 1 inch |
Horizontal runs may have a 0 inch rise per foot in all cases using SIMPSON
Only a clearance to combustibles of 1" all around the vent pipe is required.
