GENERAL INFORMATION
FOR YOUR SATISFACTION, THIS FIREPLACE HAS BEEN
TEST-FIRED TO ASSURE ITS OPERATION AND QUALITY!
Maximum input is 26,000 BTU/hr for natural gas and propane for
the CDV36. Maximum input for the BCDV36 is 17,000 BTU/h for
natural gas and 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 22,360 BTU/hr at an efficiency of 86% with the fan on, and 22,880 BTU/hr for propane
at an efficiency of 88% with the fan on. The A.F.U.E. (annual
fuel utilization efficiency) rating is 64% for natural gas and
65% for propane. These efficiency ratings apply to Model
CDV36 only.
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. The natural gas model can only be installed in a
mobile home that is permanently positioned on its site and
fueled with natural gas.
No external electricity (110 volts or 24 volts) is required for the gas system operation.
Expansion / contraction noises during heating up
and cooling down cycles are normal and are to be
expected.
CARE OF GLASS, AND PLATED PARTS
Do not use abrasive cleaners to clean plated parts. Buff lightly
with a clean dry cloth. The CDV36 is factory equipped with
ceramic glass. The BCDV36 is factory equipped with tempered glass. The glass thickness is 3/16" for both models.
Use only replacement glass available from your Continental
dealer. DO NOT SUBSTITUTE MATERIALS. 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.
The fireplace must be installed against finished
walls. Do not install against a vapour barrier or exposed insulation.
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.
FIGURE 1a - SPECIFICATIONS FOR MODEL CDV36
W415-0211 / C / 03.20.01
VENTING
MODELS CDV36 AND BCDV36 MAY BE VENTED EITHER AS A TOP VENT OR A REAR VENT.
REFER TO THE SECTION APPLICABLE TO YOUR INSTALLATION.
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 GD222, or
1/12 TO 7/12 PITCH ROOF TERMINAL KIT GD110, 8/12 T O
12/12 ROOF TERMINAL KIT GD111, FLAT ROOF TERMI-
NAL KIT GD112 or PERISCOPE KIT GD201 (for wall penetration below grade). With flexible venting, in conjunction
with the various terminations, use either the 5 foot vent kit
GD220 or the 10 foot vent kit GD330.
Wolf Steel rigid and flexible venting systems must not
be combined.
Wolf Steel and Simpson Dura-Vent venting systems
must not be combined.
These vent kits allow for either horizontal or vertical venting
of the fireplace. FIGURES 3a, & 5a. The maximum allow-
able horizontal run is 20 feet. The maximum allowable vertical vent length is 40 feet. The maximum number of 4" 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
open. Assure that a continuous gas flow is at the burner
before closing the door.
Under extreme vent configurations, allow several minutes
(5-15) for the flame to stabilize after ignition.
Six (6") inches is the minimum bend radius allowed for
the 7" diameter flexible liner.
FIGURE 1b - SPECIFICATIONS FOR MODEL BCDV36
For optimum performance it is recommended that all
horizontal runs have a 1 inch rise per foot when using
Wolf Steel 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 14 inches
top, sides and bottom of the vent pipe* 1 inch
top of the vent pipe - rear vent only* 2 inches
* REAR VENT - A clearance to combustibles of 1" at the
bottom of the vent and 2" at the top must be maintained
during the first 12" of venting when penetrating combustible walls. The firestop spacer (DV-615.044) supplied with
the unit should be used to maintain this clearance. Thereafter a 1" clearance to combustibles may be maintained
using firestop spacer (GD-500.96).
TOP VENT - Only a clearance to combustibles of 1" all
around the vent pipe is required.
