VENTING LENGTHS
Use only Wolf Steel, Simpson
American Metal Amerivent venting components. Minimum and
maximum vent lengths, for both horizontal and vertical installations,
and air terminal locations for either system are set out in this manual and must be adhered to. For Simpson
All outer pipe joints of these venting systems must be sealed using Red RTV Hight Temperature Sealant.

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 fi replace
flue collar which must be sealed using the black high temperature sealant
When using Wolf Steel venting components, use only approved Wolf Steel rigid / fl exible components with the following termination kits: WALL TERMINAL KIT GD422, or 1/12 TO 7/12 PITCH ROOF TER- MINAL KIT GD410, 8/12 TO 12/12 ROOF TERMINAL KIT GD411, FLAT ROOF TERMINAL KIT GD412 or PERISCOPE KIT GD401 (for wall penetration below grade). With fl exible 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
The air terminal must remain unobstructed at all times. Examine the air terminal at least once a year to verify that it is unob- structed 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 re- installing the door.
Under extreme vent configurations, allow several minutes
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 ver- tical 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 con- struction from fireplace and vent sur- faces:
Sides, back, bottom and | 0" |
top of the unit |
|
Recessed depth | 22" |
All around the vent pipe* | 2" |
Enclosure top | 45 1/2" |
Ceiling | 72" from bottom of unit |
*HORIZONTAL VENT SECTIONS: A minimum clearance of 2" all around the vent pipe on all horizontal runs to combustibles is required. Use fi restop spacer
VERTICAL VENT SECTIONS: A minimum of 1" all around the vent pipe on all vertical runs to combustibles is required except for clear- ances in fi replace enclosures. Use fi restop spacer
Horizontal runs may have a 0" rise per foot in all cases using
SIMPSON
For optimum performance it is recommended that all horizontal runs have a 1" rise per foot when using Napoleon® flexible vent components.
