• Do not strike or slam shut the appliance glass door, if equipped.
• Only doors / optional fronts certified with the appliance 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.
• Carbon or soot should not occur in a vent free appliance as it can distribute into the living area of your
home. If you notice any signs of carbon or soot, immediately turn off your appliance and arrange to have
it serviced by a qualified technician before operating it again.
• If equipped, the screen must be in place (closed) when the appliance is in operation.
• 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.
• Carbon monoxide poisoning may lead to death; early signs of carbon monoxide poisoning resemble the
flu, with headache, dizziness and/or nausea. If you have these signs, the appliance may not be working
properly. Get fresh air at once! Have appliance serviced. Some people; pregnant women, persons with
heart or lung disease, anemia, those under the influence of alcohol, those at high altitudes are more
affected by carbon monoxide than others. Failure to keep the primary air opening(s) of the burner(s) clean
may result in sooting and property damage.
• 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 (not applicable for outdoor appliances).
• 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 to decorations, a TV or other electronic components.

• Use only Wolf Stetel-approved optional accessories and replacement parts with this appliance. Using non-
listed accessories (blowers, doors, louvres, trims, gas components, venting components, etc.) could result in a
safety hazard and will void the warranty and certification.
• The appliance must not be operated at temperatures below freezing (32°F / -°C). Allow the appliance to warm
to above freezing prior to operation.
• This appliance has been designed and certified for indoor use only.
THIS GAS APPLIANCE MUST BE INSTALLED AND SERVICED BY A QUALIFIED INSTALLER to conform with local
codes. Installation practices vary from region to region and it is important to know the specifics that apply to your area, for
example in the state of Massachusetts:
• This product must be installed by a licensed plumber or gas fitter when installed within the commonwealth of
Massachusetts.
• The appliance damper must be removed or welded in the open position prior to installation of an appliance insert or gas
log.
• The appliance off valve must be a “T” handle gas cock.
• The flexible connector must not be longer than 36 inches (0.9m).
• A carbon monoxide detector is required in all rooms containing gas fired appliances.
• The appliance is not approved for installation in a bedroom or bathroom unless the unit is a direct vent sealed
combustion product.
The installation must conform with local codes or, in absence of local
codes, the National Gas and Propane Installation Code CSA B149.1
in Canada, or the National Fuel Gas Code, ANSI Z223.1 / NFPA 54
in the United States. Suitable for mobile home installation if installed
in accordance with the current standard CAN/CSA Z240MH Series,
for gas equipped mobile homes, in Canada or ANSI Z223.1 and
NFPA 54 in the United States.
The appliance and its individual shutoff valve must be disconnected
from the gas supply piping system during any pressure testing
of that system at test pressures in excess of 1/2 psig (35 mb).
The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (35 mb). When installed
with a blower or fan, the junction box must be electrically connected and grounded in accordance with local codes. In the
absence of local codes, use the current CSA C22.1 Canadian Electrical Code in Canada or the ANSI / NFPA 70 National

installed vertically. See "vertical venting" or "horizontal air terminal installation" section for installation.
For mobile home installations, the appliance must be fastened in place. It is recommended that the appliance be
secured in all installations. Use the levelling / securing kit, GDSLL-KT for this purpose.

venting
2.0 venting
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 1-1/4" (25.4mm - 6.4mm) air gap all around between the inner liner and outer appliance pipe is
required for safe operation. Use a firestop when penetrating interior walls, floor or ceiling.
!WARNING
• Risk of fire. Maintain specified air space clearances to vent pipe and appliance.
• The vent system must be supported every 3’(0.9m) for both vertical and horizontal runs. Use support ring assembly W010-
0067 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 spaces must not be removed.
This appliance uses a 4” (102mm) exhaust / 7” (178mm) air intake vent pipe system. Refer to the section applicable
to your installation.
For safe and proper operation of the appliance, follow the venting instructions 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. Although not a requirement, it is recommended for vent lengths that pass through
unheated spaces (attics, garages, crawl spaces) 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.
The vent terminal may be painted with a high temperature paint to match exterior colours. Use an outdoor paint suitable for
400°F (200°C). Application and performance of paint is the consumer’s responsibility. Spot testing is recommended.
note:
If for any reason the vent air intake system is disassembled, re-install per the instructions provided for the initial installation.
This appliance must be installed with a continuous connection of exhaust and air intake vent pipes. Utilizing alternate
constructions such as a chimney as part of the vent system is not permitted.
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, clearances from vent pipes to combustibles
and air terminal locations as set out in this manual apply to all vent systems 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 or on the website for your venting supplier.
A starter adaptor must be used with the following vent systems and may be purchased from the corresponding supplier:
When using Wolf Steel venting components, use only approved Wolf Steel termination kits: wall terminal kit GD-
175 (7/12" of venting included), or 1/12 to 7/12 pitch roof terminal kit GD-110, 8/12 to 12/12 roof terminal kit GD-
111, flat roof terminal kit GD-112, or periscope kit GD-180 (for wall penetration below grade) in conjunction with
the appropriate venting components.
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.

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.

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.
These vent kits allow for either horizontal or vertical venting of the appliance. The maximum allowable horizontal run is 20
feet (6.1m). The maximum allowable vertical vent length is 40 feet (12.2m). 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
• Risk of fire.
• Co-axial to co-linear venting configurations must only be used in a non-combustible chimney or enclosure.
Installation in a combustible enclosure could result in a fire.
This appliance is designed to be attached to a 3” (76.2mm) co-linear aluminum flex vent system running the full
length of a masonry chimney.
The flex liners accommodate any contours of a
masonry chimney, however, it is necessary to keep
the flexible liners as straight as possible. The inlet
air collar of the termination cap must be connected
to the air intake flex liner and the exhaust collar
must be connected to the exhaust flexible liner.
Both Simpson Duravent and Selkirk co-linear to
co-axial adaptors have been approved on this
appliance
Follow vent manufacturer’s installation instructions.
Different manufacturer’s venting
components must not be combined.
Once the preferred manufacturer’s
appliance adaptor has been attached, the
remainder of the system must be that of
the same manufacturer.
The only exception to this rule is to use

• The appliance exhaust flue collar must be sealed using Mill Pac. All exhaust and intake vent pipe joints
must be sealed using red RTV high temp silicone sealant (W573-0002) (not supplied) or black high temp Mill
Pac (W573-0007) (not supplied).
• If using pipe clamps to connect rigid vent components, a minimum of 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.
• 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.
note:
If the appliance is installed directly on carpeting, vinyl tile or other combustible material other than wood flooring,
the appliance shall be installed on a metal or wood panel extending the full width and depth.

installation
3.1.1 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” (215.9mm)
thick but the vent shield must extend the full depth of the
combustible wall.
A. Assemble the shield to the spacer as shown, using the 3
shorter screws supplied.
B. Place the firestop top so that the vent shield covers the top of
the vent within the opening. Ensure that both spacer and shield
maintain the required clearance to combustibles.
C. Secure the spacer in place using the 4 longer screws supplied.
Once the vent pipe is installed in its final position, apply sealant between the pipe and the firestop spacer.
• 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.
!WARNING
Do not fill the air space between the firestop spacer and the
exterior wall with any type of insulating material (i.e. spray foam).

3.1.2 vertical installation
This application occurs when venting through a roof. Installation kits for
various roof pitches are available from your authorized dealer / distributor.
See the “accessories” section 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"
(25mm) 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" (25mm) 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 red RTV
silicone (W573-0002) (not supplied) 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" (25mm) air space around the pipe.

3.1.3 horizontal air terminal installation - model CDVS280
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 red RTV silicone
(W573-0002) (not supplied) to the inner sleeve of the air
terminal. Slip the vent pipe a minimum of 2” (50.8mm)
over the inner sleeve of the air terminal and secure with a
minimum of 3 screws.
B. Using the outer flex pipe, slide over the outer combustion
air sleeve of the air terminal and secure with a minimum
of 3 screws. Seal using red RTV silicone (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 (0.9m) for
both vertical and horizontal runs. Use non-combustible
strapping to maintain the minimum clearance to
combustibles.
E. Stove Appliances Only: From inside the house, using
Red RTV Silicone (W573-0002) (not supplied), seal
between the vent pipe and the firestop. Then slide the black trim collar over the vent pipe up to the
firestop.
The air terminal mounting plate may be recessed into the exterior wall or siding no greater than the
depth of its return flange.
