3.0 VENTING
7.1
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. 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 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.
For horizontal runs, both Wolf Steel and Simpon Dura-Vent venting components may have a 0" rise per foot.
For optimum performance, it is recommended that all horizontal runs have a minimum 1/4" rise per foot.
All inner exhaust and outer intake vent pipe joints may be sealed using either red high temp silicone sealant or
black high temp Mill Pac with the exception of the appliance exhaust flue collar which must be sealed using Mill
Pac (not supplied).

9
W415-0496 / D / 11.05.10
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.
When using Wolf Steel venting components, use only approved Wolf Steel termination kits: wall terminal kit GD175
(7/12’ of venting included), 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 GD180 (for wall penetration below grade) in conjunction with the appropriate
venting components.
For optimum flame appearance and appliance operation, keep the vent length and number of elbows to a
minimum. It is recommended that all horizontal runs have a minimum 1/4” rise per foot. 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 manufacturers
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.
Deviation from the minimum vertical vent length can create difficulty in burner start-up and/or carboning.
Use an adjustable pipe as the final length of rigid piping to the stove for ease of installation.

!
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
4.1 WALL AND CEILING PROTECTION
For clearances to combustible materials from the vent pipe, see “MINIMUM CLEARANCE TO COMBUSTI-
BLES” section.
!
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.

4.1.2 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. 21.1

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.

B. Install the inner flex pipe to the appliance. Secure with 3 screws
and flat washers. Seal the joint and screw holes using the high
temperature sealant W573-0007 (not supplied).
C. Run a bead of high temperature sealant (not supplied) around the
inside of the air intake collar. Pull the adjustable pipe a minimum 2”
into the air intake collar.
NOTE: Ensure that the sealant is not visible on the exterior pipes once
installation is completed. An optional decorative black band is available
for this use. In the event that the venting must be disassembled, care
must be taken to reseal the venting.
TERMINALS MUST NOT BE RECESSED INTO A WALL OR SIDING MORE THAN THE DEPTH OF THE
RETURN FLANGE OF THE MOUNTING PLATE.
DO NOT ALLOW THE INNER FLEX PIPE TO BUNCH UP ON HORIZONTAL OR VERTICAL RUNS AND
ELBOWS. KEEP IT PULLED TIGHT.
!
WARNING
A. Stretch the inner flex pipe to the required length taking
into account the additional length needed for the
finished wall surface. Slip the vent pipe a minimum of 2”
over the inner sleeve of the air terminal and secure with
3 #8 screws. Apply a heavy bead of the high temperature
sealant W573-0007 Mill Pac (not supplied).
B. Using the outer rigid 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. From inside the house, using silicone, seal between the vent
pipe and the firestop. Then slide the black trim collar over the
vent pipe up to the firestop.
E. If more vent pipe needs to be used to reach the appliance,
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. 23.7A
