INTRODUCTION
GENERAL INSTRUCTIONS GENERAL INFORMATION
THIS GAS FIREPLACE SHOULD 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 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
Massachusetts.
In absence of local codes, install to the current CAN/CGA B149 Installation Code in Canada or to the National Fuel
Gas Code, ANSI Z223.1, and NFPA 54 in the United States.
Mobile home installation must conform with local codes.
In the absence of local codes, install to the current standard for gas equipped mobile housing CAN/CSA Z240 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 Community Standard ANSI/NFPA 5OIA in the United
States.
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.
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 heat circulating blower is installed, the blower
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.
Minimum clearance to combustible construction from fireplace and vent surfaces:
sides, back, bottom, and top 0 inches
vent pipe 1 inch
recessed depth (corner installation)

FOR YOUR SATISFACTION, ALL BURNER ASSEMBLIES
HAVE BEEN TEST-FIRED TO ASSURE THEIR OPERATIONS AND QUALITY! Maximum input is 30,000 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 20,400 BTU/hr at an efficiency of 68%
with the fan on.
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. Expan-
sion / contraction noises during heating up and cooling
down cycles are normal and are to be expected.
If utilizing one of Wolf Steel's trim or surround kits, follow
the framing instructions on page 14 and the finishing instructions on page 23, for removal of the top extension.
CARE OF GLASS, AND PLATED PARTS
Do not use abrasive cleaners to clean these parts. Buff
lightly with a clean dry cloth. The glass is 3/16" tempered
glass available from your Napoleon / Wolf Steel Ltd. dealer.
Do not substitute materials.
If the door glass should crack or break, do not operate the
fireplace. Replace only with a door assembly certified with
the fireplace. See DOOR, LOUVRE AND TRIM INSTALLA-
TION for removal and replacement details. 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.
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”
(ie: drywall/sheetrock), as you would finish any
other outside wall of a home. This will ensure
that clearance to combustibles is maintained
within the cavity.
5
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
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 pen-
etration 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.
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. 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
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.
Nine (9") 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.
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.
Horizontal runs may have a 0 inch rise per foot in all
cases using SIMPSON DURA-VENT or NAPOLEON
RIGID OR FLEXIBLE venting components when venting.
A clearance to combustibles of 1" all around the vent
pipe is required.

For vent configurations requiring more than one 45º and
90° elbow the following formulas apply:
Formula 1: HT < 4.2 V
T
Formula 2: HT + VT < 24.75 feet
Formula 1: HT < 4.2 V

4.2 VT = 4.2 x 4 = 16.8 ft
10.9 < 16.8
Formula 2: HT + VT < 24.75 feet
14.9 < 24.75
Since both formulas are met, this vent configuration is acceptable.
