2.0 VENTING

Risk of fire, maintain specified air space clearances to vent pipe and appliance.
THIS FIREPLACE USES A 4" EXHAUST / 7" 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.
2.1

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
Duravent
Amerivent
Direct Temp
SuperSeal
* For Simpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent and Metal-Fab follow the installation
procedure found on the website for your venting 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 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 GD222, GD222R, 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.
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.
W415-0210 / S /03.10.09
Models GD36 and BGD36 may be vented either as a top vent or a rear vent.
