• Ensure you have incorporated adequate safety measure to protect infants/toddlers from touching hot surfaces.
• 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
combustible materials to overheat and catch fire.

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 B36DF 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.
• A carbon monoxide detector is required in all rooms containing
gas fired appliances
• 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
Massachusetts.
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 Standard 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
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.
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 B36DF is factory equipped with
tempered glass. The glass thickness is 3/16". Use only replacement glass available from your Napoleon® 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.
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.
FOR YOUR SATISFACTION, THIS FIREPLACE HAS BEEN
TEST-FIRED TO ASSURE ITS OPERATION AND QUALITY!
Maximum input is 23,000 BTU/hr 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 and propane is 15,200 BTU/
hr at an efficiency of 66% with the fan on. The maximum A.F.U.E.
(annual fuel utilization efficiency) rating is 62% for natural gas
and propane.
W415-0484 / C / 10.15.07
FIGURE 1
VENTING
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.
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.
VENTING LENGTHS
Use only Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp or
American Metal Amerivent venting components.
For Simpson Dura-Vent, Selkirk Direct Temp and American Metal
Amerivent, follow the installation procedure provided with the
venting components.
All outer pipe joints of these venting systems must be sealed
using Red RTV High Temperature Sealant.
Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp and American
Metal Amerivent venting systems must not be combined.
A starter adaptor must be used and may be purchased from the
corresponding supplier:
PART 5"/8" SUPPLIER
Duravent W175-0170 Wolf Steel
Amerivent 5DSC-N American Metal
Direct Temp 5DT-AAN Selkirk
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 maybe 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 fireplace 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, 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.
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 reinstalling 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 Napoleon® 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.
Objects placed in front of the fireplace must be kept a
minimum of 48" away from the front face of the unit.
Minimum clearance to combustible construction from fireplace and vent surfaces:
sides, back and bottom 0" (to stand off)
top (framing) 7 1/2"
finishing 0"
recessed depth 21"
sides and bottom of the vent pipe 1"
top of vent 2"
Horizontal runs may have a 0 inch rise per foot in all cases using
Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp, or American
Metal Amerivent rigid vent components and Wolf Steel flexible
vent components. For optimum performance, it is recommended
that horizontal runs have a minimum 1/4 inch rise per foot when
using Simpson Dura-Vent, Selkirk Direct Temp, American Metal
Amerivent or Wolf Steel rigid vent components and a minimum 1
inch rise per foot when using Wolf Steel flexible vent components.
For safe and proper operation of the fireplace, follow the venting
instructions exactly.
