• Young children should be carefully supervised when they are in the same room as the appliance.
Toddlers, young children and others may be susceptible to accidental contact burns. A physical barrier
is recommended if there are at risk individuals in the house. To restrict access to an appliance or stove,
install an adjustable safety gate to keep toddlers, young children and other at risk individuals out of the
room and away from hot surfaces.
• Clothing or other flammable material should not be placed on or near the appliance.
• Due to high temperatures, the appliance should be located out of traffic and away from furniture and
draperies.
• Ensure you have incorporated adequate safety measure to protect infants/toddlers from touching hot
surfaces.
• Even after the appliance is out, the glass and/or screen will remain hot for an extended period of time.
• Check with your local hearth specialty dealer for safety screens and hearth guards to protect children
from hot surfaces. These screens and guards must be fastened to the floor.
• Any safety screen or guard removed for servicing must be replaced prior to operating the appliance.
• It is imperative that the control compartments, burners and circulating blower and its passageway in the
appliance and venting system are kept clean. The appliance and its venting system should be inspected
before use and at least annually by a qualified service person. More frequent cleaning may be required
due to excessive lint from carpeting, bedding material, etc. The appliance area must be kept clear and
free from combustible materials, gasoline and other flammable vapors and liquids.
• Under no circumstances should this appliance be modified.
• This appliance must not be connected to a chimney flue pipe serving a separate solid fuel burning
appliance.
• Do not use this appliance if any part has been under water. Immediately call a qualified service
technician to inspect the appliance and to replace any part of the control system and any gas control
which has been under water.
• Do not operate the appliance with the glass door removed, cracked or broken. Replacement of the glass
should be done by a licensed or qualified service person.
• Do not strike or slam shut the appliance glass door.
• When equipped with pressure relief doors, they must be kept closed while the appliance is operating
to prevent exhaust fumes containing carbon monoxide, from entering into the home. Temperatures of
the exhaust escaping through these openings can also cause the surrounding combustible materials to
overheat and catch fire.
• Only doors / optional fronts certified with the unit are to be installed on the appliance.
• Keep the packaging material out of reach of children and dispose of the material in a safe manner. As
with all plastic bags, these are not toys and should be kept away from children and infants.
• As with any combustion appliance, we recommend having your appliance regularly inspected and
serviced as well as having a Carbon Monoxide Detector installed in the same area to defend you and
your family against Carbon Monoxide.
• Ensure clearances to combustibles are maintained when building a mantel or shelves above the
appliance. Elevated temperatures on the wall or in the air above the appliance can cause melting,
discolouration or damage of decorations, a T.V. or other electronic components.

3.0 VENTING
3.1 VENTING LENGTHS AND COMPONENTS 7.2
THIS APPLIANCE USES A 5” EXHAUST / 8” 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.
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.
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.

W415-0869 / A / 06.10.10
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 1/4” 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

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
4.0 INSTALLATION
4.1 WALL AND CEILING PROTECTION
For optimum performance it is recommended that all horizontal runs have a minimum of 1/4” rise per foot using
flexible venting. For safe and proper operation of the appliance, follow the venting instructions exactly.
!
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.

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.
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

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 USING FLEXIBLE VENT COMPONENTS
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 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. 23.1
