3.0 VENTING
7.1A
THIS APPLIANCE USES A 4” EXHAUST / 7” AIR INTAKE VENT PIPE SYSTEM.
Refer to the section applicable to your installation.
For safe and proper operation of the appliance 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. Provide a means for
visually checking the vent connection to the appliance after the appliance 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.
!
WARNING
RISK OF FIRE, MAINTAIN SPECIFIED AIR SPACE CLEARANCES TO VENT PIPE AND APPLIANCE.
IF VENTING IS INCLUDED WITH SPACERS THE VENT SYSTEM MUST BE SUPPORTED EVERY 3 FEET
FOR BOTH VERTICAL AND HORIZONTAL RUNS. USE SUPPORTS OR EQUIVALENT
NON-COMBUSTIBLE STRAPPING TO MAINTAIN THE REQUIRED CLEARANCE FROM
COMBUSTIBLES. USE WOLF STEEL LTD. SUPPORT RING ASSEMBLY W010-0370 OR EQUIVALENT
NON-COMBUSTIBLE STRAPPING TO MAINTAIN THE MINIMUM CLEARANCE TO COMBUSTIBLES
FOR BOTH VERTICAL AND HORIZONTAL RUNS. SPACERS ARE ATTACHED TO THE INNER PIPE AT
PREDETERMINED INTERVALS TO MAINTAIN AN EVEN AIR GAP TO THE OUTER PIPE. THIS GAP IS
REQUIRED FOR SAFE OPERATION. A SPACER IS REQUIRED AT THE START, MIDDLE AND END OF
EACH ELBOW TO ENSURE THIS GAP IS MAINTAINED. THESE SPACERS MUST NOT BE REMOVED.

W415-0570 / E / 04.23.12
3.1 VENTING LENGTHS AND COMPONENTS
Use only Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent or Metal-Fab 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 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:
For Simpson Dura-Vent, Selkirk Direct Temp,American MetalAmerivent 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 appliance flue collar which must
be sealed using the black high temperature sealant Mill Pac. High temperature sealant must be ordered separately.
When using Wolf Steel venting components, use only approved Wolf Steel rigid / flexible components with the following
termination kits: wall terminal kit 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 appliance 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 appliance. 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 appliance 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” rise per foot using flexible venting. For safe and proper operation of the appliance, follow the
venting instructions exactly.
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 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.

4.0 INSTALLATION
4.1 WALL AND CEILING PROTECTION
For clearances to combustible materials from the vent pipe, see “FRAMING” section.
For optimum performance it is recommended that all horizontal runs have a minimum 1” rise per foot when us-
ing flexible venting.
!
WARNING
FOR SAFE AND PROPER OPERATION OF THE APPLIANCE, FOLLOW THE VENTING INSTRUCTIONS
EXACTLY.
ALL INNER EXHAUST AND OUTER INTAKE VENT PIPE JOINTS MAY BE SEALED USING EITHER RED
RTV HIGH TEMP SILICONE SEALANT W573-0002 (NOT SUPPLIED) OR BLACK HIGH TEMP MILL PAC
W573-0007 (NOT SUPPLIED) WITH THE EXCEPTION OF THE APPLIANCE EXHAUST FLUE COLLAR
WHICH MUST BE SEALED USING MILL PAC.
IF USING PIPE CLAMPS TO CONNECT VENT COMPONENTS, 3 SCREWS MUST ALSO BE USED TO
ENSURE THE CONNECTION CANNOT SLIP OFF.
DO NOT CLAMP THE FLEXIBLE VENT PIPE.
RISK OF FIRE, EXPLOSION OR ASPHYXIATION. IMPROPER SUPPORT OF THE ENTIRE VENTING
SYSTEM MAY ALLOW VENT TO SAG AND SEPARATE. USE VENT RUN SUPPORTS AND CONNECT
VENT SECTIONS PER INSTALLATION INSTRUCTIONS.
RISK OF FIRE, DO NOT ALLOW LOOSE MATERIALS OR INSULATION TO TOUCH THE VENT PIPE.
REMOVE INSULATION TO ALLOW FOR THE INSTALLATION OF THE ATTIC SHIELD AND TO
MAINTAIN CLEARANCES TO COMBUSTIBLES.
68.2A
!
WARNING
DO NOT FILL THE SPACE BETWEEN THE VENT PIPE AND ENCLOSURE WITH ANY TYPE OF
MATERIAL. DO NOT PACK INSULATION OR COMBUSTIBLES BETWEEN CEILING FIRESTOPS.
ALWAYS MAINTAIN SPECIFIED CLEARANCES AROUND VENTING AND FIRESTOP SYSTEMS.
INSTALL WALL SHIELDS AND FIRESTOPS AS SPECIFIED. FAILURE TO KEEP INSULATION OR
OTHER MATERIALS AWAY FROM VENT PIPE MAY CAUSE FIRE.

4.1.1 HORIZONTAL SHIELDING
This application occurs when venting through an exterior wall.
Having determined the correct height for the air terminal
location, cut and frame a hole in the exterior wall as
illustrated to accommodate the firestop assembly.
Dry fit the firestop assembly before proceeding to
ensure the brackets on the rear surface fit to the
inside surface of the horizontal framing.
The length of the vent shield may be cut shorter
for combustible walls that are less than 8 1/2” thick
but the vent shield must extend the full depth of the
combustible wall.
A. Apply a bead of caulking (not supplied) around the corner edge of
the inside surface of the firestop assembly, fit the firestop assembly
to the hole and secure using the 4 screws (supplied in your manual
baggie).
B. Once the vent pipe is installed in its final position, apply high
temperature sealant W573-0007 (not supplied) between
the pipe and the firestop.

4.1.2 VERTICAL SHIELDING
This application occurs when venting through a roof. Installation kits for
various roof pitches are available from your authorized dealer / distributor. See
accessories to order specific kits required.
A. Determine the air terminal location, cut and frame a square opening as
illustrated in the ceiling and the roof to provide the minimum 1“ clearance
between the vent pipe and any combustible material. Try to center the vent
pipe location midway between two joists to prevent having to cut them. Use
a plumb bob to line up the center of the openings. A vent pipe shield will
prevent any materials such as insulation, from filling up the 1” air space
around the pipe. Nail headers between the joist for extra support.
B. Apply a bead of caulking (not supplied) to the framework or to the Wolf
Steel vent pipe shield plate or equivalent (in the case of a finished
ceiling), and secure over the opening in the ceiling. A firestop must be
placed on the bottom of each framed opening in a roof or ceiling that the
venting system passes through. Apply a bead of caulking all around and place a
firestop spacer over the vent shield to restrict cold air from being drawn into the
room or around the fireplace. Ensure that both spacer and shield maintain the
required clearance to combustibles. Once the vent pipe is installed in its final
position, apply sealant between the pipe and the firestop assembly.
C. In the attic, slide the vent pipe collar down to cover up the open end of the shield and
tighten. This will prevent any materials, such as insulation, from filling up the 1” air space
around the pipe.

4.2 USING FLEXIBLE VENT COMPONENTS
For safe and proper operation of the appliance, follow the venting
instructions exactly.
All inner flex pipe and outer flex pipe joints may be sealed using high
temperature sealant W573-0002 (not supplied) or the high temperature
sealant W573-0007 Mill Pac (not supplied). However, the high temperature
sealant W573-0007 Mill Pac (not supplied) must be used on the joint
connecting the inner flex pipe and the exhaust flue collar.
Use only approved flexible vent pipe kits marked:
“Wolf Steel Approved Venting” as identified
by the stamp only on the outer flex pipe.
22.1
ELBOW
SPACERS
DO NOT ALLOW THE INNER FLEX PIPE TO BUNCH UP ON HORIZONTAL OR VERTICAL RUNS AND ELBOWS.
KEEP IT PULLED TIGHT.
SPACERS ARE ATTACHED TO THE INNER FLEX PIPE AT PREDETERMINED INTERVALS TO MAINTAIN AN EVEN
AIR GAP TO THE OUTER FLEX PIPE. THIS GAP IS REQUIRED FOR SAFE OPERATION. A SPACER IS REQUIRED
AT THE START, MIDDLE AND END OF EACH ELBOW TO ENSURE THIS GAP IS MAINTAINED. THESE SPACERS
MUST NOT BE REMOVED.
!
WARNING
4.2.1 HORIZONTAL AIR TERMINAL INSTALLATION
A. Stretch the inner flex pipe to the required
length needed for the finished wall surface.
Apply a heavy bead of high temperature
sealant W573-0007 Mill Pac (not supplied)
to the inner sleeve of the air terminal. Slip
the vent pipe a minimum of 2” over the inner
sleeve of the air terminal and secure with 3
#8 screws.
B. Using the outer flex pipe, slide over the outer
combustion air sleeve of the air terminal
and secure with 3 #8 screws. Seal using
high temperature sealant W573-0002 (not
supplied).
C. Insert the vent pipes through the firestop
maintaining the required clearance to
combustibles. Holding the air terminal (lettering
in an upright, readable position), secure to the
exterior wall and make weather tight by sealing
with caulking (not supplied).
D. If more vent pipe needs to be used to reach
the fireplace, couple them together as
illustrated. The vent system must be supported
approximately every 3 feet for both vertical and
horizontal runs. Use noncombustible strapping
to maintain the minimum 1” clearance to
combustibles.
The air terminal mounting plate may be recessed into the exterior wall or siding no greater than the depth
of its return flange. 23.3A
