GENERAL INSTRUCTIONS
THIS GAS FIREPLACE SHOULD BE INSTALLED AND SERVICED BY A QUALIFIED INSTALLER to conform with local codes.
In absence of local codes, install the BCDV42 to the current
National Fuel Gas Code, ANSI Z223.1, or the current
CAN/CGA B149, Installation Codes.
Installation practices vary from region to region and it is
important to know the specifics that apply to your area,
for example: in Massachusetts State:
• The fireplace damper must be removed or welded in the open
position prior to installation of a fireplace 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.
• The appliance is not approved for installation in a bedroom or
bathroom unless the unit is a direct vent sealed combustion
product.
• WARNING: This product must be installed by a licensed plumber
or gas fitter when installed within the commonwealth of Mas
sachusetts.
Mobile home installation must conform with local codes or in the
absence of local codes, install to the current standard for gas
equipped mobile housing CAN/CSA ZA240 MH Series in Canada
or the Manufactured Home Construction and Safety Standard,
Title 24 CFR, Part 3280, or the Fire Safety Criteria for Manufactured Home Installations, Sites and Communities St andard ANSI/
NFPA 501A in the United States.
The fireplace 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
(3.5 kPa). The fireplace 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 (3.5 kPa).
When the fireplace is installed directly on carpeting, vinyl tile
or other combustible material other than wood flooring, the
fireplace shall be installed on a metal or wood panel extending the full width and depth.
If the optional fan or blower is installed, 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 ELECTRICAL CODE in the United
States.
GENERAL INFORMATION
FOR YOUR SATISFACTION, THIS FIREPLACE HAS BEEN
TEST-FIRED TO ASSURE ITS OPERATION AND QUALITY!
Maximum input is 28,500 BTU/hr for natural gas and 24,000
BTU/hr for propane. When the fireplace is installed at elevations
above 4,500ft, and in the absence of specific recommendations
from the local authority having jurisdiction, the certified high altitude input rating shall be reduced at the rate of 4% for each
additional 1,000ft.
Maximum output for natural gas is 19,500 BTU/hr at an efficiency of 68.5% with the fan on, and 16,000 BTU/hr for propane at an efficiency of 67% with the fan on. The maximum
A.F.U.E. (annual fuel utilization efficiency) rating is 64% for
natural gas and 61.5% for propane.
Minimum inlet gas supply pressure is 4.5 inches water column for natural gas and 11 inches water column for propane.
Maximum inlet gas pressure is 7 inches water column for
natural gas and 13 inches water column for propane. Manifold pressure under flow conditions is 3.5 inches water column for natural gas and 10 inches water column for propane.
This fireplace is approved for bathroom, bedroom and bedsitting room installations and is suitable for mobile home
installation.

CARE OF GLASS, AND PLATED PARTS
Do not use abrasive cleaners to clean plated parts. Buff lightly
with a clean dry cloth. The BCDV42 is factory equipped with
tempered glass. The glass thickness is 3/16". Use only replacement glass available from your Continental dealer. DO
NOT SUBSTITUTE MA TERIALS. Clean the glass after the first
10 hours of operation with a recommended gas fireplace
glass cleaner. Thereafter clean as required. DO NOT CLEAN
GLASS WHEN HOT! If the glass is not kept clean permanent
discolouration and / or blemishes may result.
Use only accessories designed for and listed with
your specific fireplace.
Provide adequate ventilation air. Provide adequate accessibility clearance for servicing and operating the
fireplace. Never obstruct the front opening of the fireplace.
For safe and proper operation of the fireplace follow the
venting instruction exactly.
Deviation from the minimum vertical vent length can
create difficulty in burner start-up and/or carboning.
Provide a means for visually checking the vent connection to the fireplace after the fireplace is installed.
In order to avoid the possibility of exposed insulation or
vapour barrier coming in contact with the fireplace body,
it is recommended that the walls of the fireplace enclosure be 'finished', (i.e. drywall/sheetrock) as would any
other outside wall of the home. This will ensure that
clearance to combustibles is maintained within the cavity.
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.
Objects placed in front of the fireplace must be kept a
minimum of 48" away from the front face of the unit.
W415-0385 / A / 10.02.03
VENTING

FIGURE 1
VENTING LENGTHS
Use only Wolf Steel or Simpson Dura-Vent Model DV-GS
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, follow
the installation procedure provided with the venting components.
When using Wolf Steel venting components, use only approved Wolf Steel rigid / flexible components with the following termination kits: WALL TERMINAL KIT GD422, or
1/12 TO 7/12 PITCH ROOF TERMINAL KIT GD410, 8/12 TO
12/12 ROOF TERMINAL KIT GD411, FLAT ROOF TERMI-
NAL 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.
It is recommended to attach the Wolf Steel 45º rigid adaptor directly to the unit when terminating horizontally off
the back of the unit. This must be done before attaching
the desired vent system. Once this transition has been
made, venting systems must not be combined.
These vent kits allow for either horizontal or vertical venting
of the fireplace. FIGURES 3 & 5. The maximum allowable
horizontal run is 20 feet. The maximum allowable vertical
vent length is 40 feet. The maximum number of 5" vent
connections is two horizontally or three vertically (excluding the fireplace and the air terminal connections) when
using aluminum flexible venting.
For optimum flame appearance and fireplace 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.
Purge all gas lines with the glass door of the fireplace
removed. Assure that a continuous gas flow is at the
burner before re-installing the door.
Under extreme vent configurations, allow several minutes
(5-15) for the flame to stabilize after ignition.
Eight (8") inches is the minimum bend radius allowed
for the 8" diameter flexible liner.
For optimum performance it is recommended that all
horizontal runs have a 1 inch rise per foot when using
Continental flexible vent components.
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 1¼" air
gap all around between the inner liner and outer liner is
required for safe operation. Use a firestop when penetrating interior walls, floor or ceiling.
Minimum clearance to combustible construction from fireplace and vent surfaces:
sides, back, bottom and top of the unit 0 inch
recessed depth 22 inches
top, sides and bottom of the vent pipe 1 inch
vent heat shield 1 inch
Horizontal runs may have a 0 inch rise per foot in all
cases using SIMPSON DURA-VENT or CONTINENTAL
RIGID OR FLEXIBLE venting components when venting as illustrated in Figures 3, and 4.
Only a clearance to combustibles of 1" all around the
vent pipe is required.
