2.0 VENTING

Risk of fire, maintain specified air space clearances to vent pipe and appliance.
THIS FIREPLACE USES A 5" EXHAUST / 8" AIR INTAKE VENT PIPE SYSTEM.
For safe and proper operation of the fireplace follow the venting instruction exactly. Deviation from the minimum
vertical vent length can create difficulty in burner start-up and/or carboning. Under extreme vent configurations,
allow several minutes (5-15) for the flame to stabilize after ignition. 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.
NOTE: If for any reason the vent air intake system is disassembled; reinstall per the instructions provided
for the initial installation.
Horizontal runs may have a 0" rise per foot in all cases using Simpson Dura-Vent, Selkirk Direct Temp, American Metal
Amerivent or Napoleon® rigid or fl exible venting components when venting, see "TYPICAL VENT INSTALLATIONS" section.
For optimum performance it is recommended that all horizontal runs have a 1" rise per foot when using Napoleon® fl exible vent
components. For clearance to combustible materials from the vent pipe, see "FRAMING" section.

VENTING LENGTHS AND COMPONENTS

Use only Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent or Metal-Fab venting compo-
nents. 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 Dura-Vent, Selkirk Direct Temp, American
Metal Amerivent and Metal-Fab follow the installation procedure provided with the venting components.
A starter adaptor must be used with the following vent systems and may be purchased from the corresponding supplier:
PART 5" / 8"
Duravent W175-0170
Amerivent 5DSC-N2
Direct Temp 5DT-AA
SuperSeal 5DDA
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 may be 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 temperature sealant Mill Pac.
When using Wolf Steel venting components, use only approved Wolf Steel rigid / flexible components with the following
termination kits: wall terminal kit GD422-1, GD422R-1, or 1/12 to 7/12 pitch roof terminal 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 flexible
venting, in conjunction with the various terminations, use either the 5 foot vent kit GD420 or the 10 foot vent kit GD430.
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.
Rigid and flexible venting systems must not be combined. Different venting manufacturer components must not be
combined.
These vent kits allow for either horizontal or vertical venting of the fireplace. The maximum allowable horizontal run is 20 feet.
The maximum allowable vertical vent length is 40 feet. The maximum number of vent connections is two horizontally or three
vertically (excluding the fireplace and the air terminal connections) when using flexible venting.
Horizontal runs may have a 0" rise per foot however for optimum performance it is recommended that all horizontal runs
have a minimum 1/4" rise per foot using flexible venting. For safe and proper operation of the fireplace, follow the venting
instructions exactly.
When terminating vertically, the vertical rise is a minimum 3 feet and a maximum 40 feet from the top of the fireplace.
