W415-0673 / E / 10.30.12
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 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 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 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 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.

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.
70.1
!
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.

4.1.1 HORIZONTAL INSTALLATION
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.

WARNING
THE FIRESTOP ASSEMBLY MUST BE INSTALLED WITH THE VENT SHIELD TO THE TOP.
TERMINALS MUST NOT BE RECESSED INTO A WALL OR SIDING MORE THAN THE DEPTH OF THE
RETURN FLANGE OF THE MOUNTING PLATE.
4.1.2 VERTICAL INSTALLATION
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 taking into
account the additional length needed for the finished wall
surface. Apply a heavy bead of the 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 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. 23.1A
