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 specifi cs that apply to your
area,
for example: in Massachusetts State:

• The fi replace damper must be removed or welded in the open
position prior to installation of a fi replace insert or gas log.

• A carbon monoxide detector is required in all rooms containing

gas fi red appliances.

• The appliance off valve must be a “T” handle gas cock.

• The fl exible 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 fi tter when installed within the commonwealth of
Massachusetts.

In absence of local codes, install to the current CAN1-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 501A in the United States.

Objects placed in front of the fi replace must be kept a
minimum of 48" away from the front face of the unit.

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 ½ psig (3.5 kPa). The fi replace 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 ½ psig
(3.5 kPa).

When the fi replace is installed directly on carpeting, vinyl tile
or other combustible material other than wood fl ooring, the
fi replace shall be installed on a metal or wood panel extending
the full width and depth.

The fireplace, when installed with a 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.

FOR YOUR SATISFACTION, THIS FIREPLACE HAS
BEEN TEST-FIRED TO ASSURE ITS OPERATION AND
QUALITY!

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. When
the valve is set to "HI", the manifold pressure under fl ow
conditions is 3.5 inches water column for natural gas and
10 inches water column for 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.
Expansion / contraction noises during heating up and cooling
down cycles are normal and to be expected.

This appliance is only for use with the type of gas indicated
on the rating plate. This appliance is not convertible for use
with other gases, unless a certifi ed kit is used.

Maximum input is 11,500 BTU/hr for natural gas. Maximum
output for natural gas is 8,600 BTU/hr at an effi ciency of 75%.
Maximum input is 11,000 BTU/hr for propane. Maximum output
for propane gas is

8,250 BTU/hr at an effi ciency of 75%.

Provide adequate accessibility clearance for servicing and

operating the fi replace.

Never obstruct the front opening of the fi replace.

Provided that the clearance to combustibles are achieved,
the most desirable and benefi cial location for a Napoleon®
fi replace is in the centre of a building, thereby allowing
the most effi cient use of the heat created. The location of
windows, doors and the traffi c fl ow in the room where the
fi replace is to be located should be considered. If possible,
you should choose a location where the vent will pass
through the house without cutting a fl oor or roof joist.

RATING LABEL LOCATION: The rating label is located

under the control panel and is chained to the fi replace.

DO NOT REMOVE.

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" ceramic glass available from your Napoleon®
/ Wolf Steel Ltd. dealer. DO NOT SUBSTITUTE MATERIALS.
Clean the glass after the fi rst 10 hours of operation with a
recommended gas fi replace 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.

VENTING LENGTHS AND AIR TERMINAL LOCATIONS CONTINUED

When using Wolf Steel venting components, use only
approved Wolf Steel rigid / fl exible components with the
following termination kits:Wall Terminal Kit GD222, or
1/12 to 7/12 Pitch Roof Terminal Kit GD110, 8/12 to 12/12
Roof Terminal Kit GD111, Flat Roof Terminal Kit GD112 or
Periscope Kit GD201 (for wall penetration below grade).
With fl exible venting, in conjunction with the various
terminations, use either the 5 foot Vent Kit GD220 or the 10
foot Vent Kit GD330.

The maximum allowable vertical vent length is 35 feet,
the minimum is 3 feet.

VENT INSTALLATIONS

For safe and proper operation of the fi replace follow the venting instruction exactly.

Deviation from the minimum or the maximum vertical vent length can create diffi culty in burner start-up and/or
carboning.

Under extreme vent confi gurations, allow several minutes (5-15) for the fl ame to stabilize after ignition.

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.

Provide a means for visually checking the vent connection to the fi replace after the fi replace is installed.

Use a fi restop, vent pipe shield or attic insulation shield when penetrating interior walls, fl oor or ceiling.

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.
Horizontal runs may have a 0" rise per foot in all cases using
Wolf Steel or Simpson Dura-Vent rigid, Selkirk Direct Temp,
American Metal Amerivent or Wolf Steel fl exible venting
components when venting.
For optimum performance, it is recommended that horizontal
runs have a minimum 1" rise per foot when using any of
these vent systems.

Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp and
American Metal Amerivent venting systems must not be
combined.

HORIZONTAL VENT SECTIONS

A minimum clearance of 1" at the bottom and sides and 2" at the top of the vent pipe in all horizontal runs to
combustibles is required. Use fi restop spacer W010-1774 (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. See "Minimum Enclosure Clearances" section. Use fi restop spacer W500-0096 (not

supplied).
