GENERAL INSTRUCTIONS
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.
• A Carbon Monoxide detector is required in all rooms containing gas fired appliances.
• 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. Suitable for mobile home installation if installed in accordance with the current standard
CAN/CSA Z240MH Series, for gas equipped mobile homes, in Canada or ANSI Z223.1 and NFPA 54 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.
The optional heat circulating blower is supplied with a cord. If 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
NSI/NFPA 70 national electrical code 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.
Provide adequate ventilation and combustion air. Provide adequate accessibility clearance for servicing and operating the fireplace.
Never obstruct the front opening of the fireplace.
Objects placed in front of the fireplace must be kept a minimum of 48” from the front face of the unit.
It is recommended that the walls of the fireplace enclosure be finished. This would ensure that clearance to combustibles is maintained
with the cavity.
Non-combustible finishing material (i.e.. cement board, brick, stone, tile) must be used to finish the front of the unit.
GENERAL INFORMATION
FOR YOUR SATISFACTION, THIS FIREPLACE HAS BEEN TEST-FIRED TO ASSURE ITS OPERATION AND QUALITY! Maximum input is
50,000 BTU/hr for both natural gas and propane. When the fi replace is installed at elevations above 4,500ft, and in the absence of specifi c
recommendations from the local authority having jurisdiction, the certifi ed high altitude input rating shall be reduced at the rate of 4% for
each additional 1,000ft. Maximum output for natural gas is 33,540 BTU/hr at an effi ciency of 63%; and 34,000 BTU/hr for propane at an
effi ciency of 61%. Minimum inlet gas supply pressure is 4.5“ water column for natural gas and 11“ water column for propane. Maximum inlet
gas pressure is 7“ water column for natural gas and 13“ water column for propane. Manifold pressure under fl ow conditions is 3.5 inches
water column for natural gas and 10 inches water column for propane.
This fi replace is approved for bathroom, bedroom and bed-sitting room installations and is certifi ed 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.
This fireplace is only for use with the type of gas indicated on the rating plate. This
fireplace is not convertible for use with other gases, unless a certified kit is used.
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. Change in flame appearance from “HI” to “LO” is more evident
in natural gas than in propane.
We Suggest that our gas
hearth products be installed
and serviced by professionals who are certified in the
U.S. by the National
Fireplace Institute (NFI) as
NFI Gas Specialists.
CARE OF GLASS
Do not use abrasive cleaners to clean plated parts. Buff lightly with a
clean dry cloth. Refer to “REPLACEMENT PARTS” to find out what
this product is equipped with and the thickness of the glass.
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 discoloration and / or blemishes may result.

VENTING
VENTING LENGTHS AND AIR TERMINAL
LOCATIONS
For safe and proper operation of the fi replace follow the venting
instuction 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.
When using NAPOLEON® venting components, use only approved
Wolf Steel Ltd. fl exible vent components with the following termination kits: WALL TERMINAL KIT GD622, or 1/12 TO 7/12 PITCH
ROOF TERMINAL KIT GD610, 8/12 TO 12/12 ROOF TERMINAL KIT
GD611, FLAT ROOF TERMINAL KIT GD612. With fl exible venting, in
conjunction with the various terminations, use either the 5 foot vent
kit GD620 or the 10 foot vent kit GD630. These vent kits allow for
either horizontal or vertical venting of the fi replace.
The maximum allowable vertical vent length is 40 feet. The
maximum number of allowable 8” vent connections is three hori-
zontally or vertically (excluding the fi replace and the air terminal
connections).
For optimum fl ame appearance and fi replace 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.
When venting, the horizontal run must be kept to a maximum
of 20 feet. If a 20 foot horizontal run is required, the fireplace
must have a minimum vertical rise immediately off the fireplace of 57“. When terminating vertically, the vertical rise is
a minimum 3 feet and a maximum 40 feet above the fireplace.

* For optimum performance, it is recommended that all hori-
zontal runs have a minimum ¼“ rise per foot.
Provide a means for visually checking the vent connection to
the fireplace after the fireplace is installed.
Do not allow the inside liner to bunch up on horizontal or vertical
runs and elbows. Keep it pulled tight. A 3/4” air gap between the
inner and outer liner all around is required for safe operation.
Use a firestop when penetrating interior walls, floor or ceiling.
For safe and proper operation of the fireplace follow the venting
instruction exactly.
If vertical rises greater than 57“ are necessary, the increased
rise must be deducted from the horizontal run.
HORIZONTAL VENT SECTIONS: A minimum clearance of 2” all
around the vent pipe on all horizontal runs to combustibles is required
except for clearances in fi replace enclosures**. Use fi restop spacer
assembly W010-1797 (supplied).
VERTICAL VENT SECTIONS: A minimum of 1” all around the vent
pipe on all vertical runs to combustibles is required except for clearances in fi replace enclosures**. Use fi restop spacer W615-0075
(not supplied).
W415-0580 / B / 03.12.08
** Horizontal and vertical sections require 5” and 9” clearance from
combustibles, respectively. See minimum enclosure clearances
