Use only Wolf Steel, Simpson Dura-Vent, Selkirk Direct
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 Dura-Vent, Selkirk Direct Temp and
American Metal Amerivent, follow the installation procedure
provided with the venting components.
All outer pipe joints of these venting systems must be
sealed using Red RTV Hight Temperature Sealant.
Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp and
American Metal Amerivent venting systems must not be
combined.
A starter adaptor must be used and may be purchased
from the corresponding supplier:
Supplier 4&7 ZC 5&8 ZC GAS STOVE
Dura-Vent W175-0053 W175-0170 GDS924N
Amerivent 4DSC-N2 5DSC-N 4DSCB-N1
Direct Temp 4DT-AAN 5DT-AA 4DT-AAN
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 re-installing the door.
Under extreme vent configurations, allow several minutes
(5-15) for the flame to stabilize after ignition.
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.
FIGURE 1
Horizontal runs may have a 0 inch rise per foot in all
cases using SIMPSON DURA-VENT or NAPOLEON
RIGID OR FLEXIBLE venting components when vent-
ing as illustrated in Figures 3, and 4.
Only a clearance to combustibles of 1" all around the
vent pipe is required.
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
