• Even after the fireplace 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 fireplace.

• It is imperative that the control compartments, burners and circulating blower and its passageway in the fireplace and venting
system are kept clean. The fireplace 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 fireplace
area must be kept clear and free from combustible materials, gasoline and other flammable vapours and liquids.

• Under no circumstances should this fireplace be modified.

• This fireplace must not be connected to a chimney flue pipe serving a separate solid fuel burning appliance.

• Do not use this fireplace if any part has been under water. Immediately call a qualified service technician to inspect the fireplace
and to replace any part of the control system and any gas control which has been under water.

• Do not operate the fireplace 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 fireplace glass door.

• This fireplace uses and requires a fast acting thermocouple. Replace only with a fast acting thermocouple supplied by Wolf
Steel Ltd.

• Pressure relief doors must be kept closed while the fireplace 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

VENTING

THE BCDV36CF(G) USES: 4" EXHAUST / 7" AIR INTAKE VENT PIPE

MODEL BCDV36CF MAY BE VENTED EITHER AS A TOP VENT OR A REAR VENT.

For safe and proper operation of the fi replace follow the venting instruction exactly. Deviation from the minimum vertical
vent length can create diffi culty in burner start-up and/or carboning. Provide a means for visually checking the vent con­nection to the fi replace after the fi replace is installed. 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.

Use only Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp or American Metal Amerivent 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 and American Metal Amerivent, 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:
