PRODUCT FEATURES
OPERATION
This vent-free fireplace insert is clean burning. It
requires no outside venting. There is no heat loss
out a vent or up a chimney. Heat is generated by
both realistic flames and glowing embers. When
used without the blower, the fireplace insert re-
quires no electricity making it ideal for emergency
backup heat.
SAFETY DEVICE
This fireplace insert has a pilot with an Oxygen
Depletion Sensing (ODS) safety shutoff system.
The ODS/pilot is a required feature for vent-free
room heaters. The ODS system shuts off the fire-
place insert if there is not enough fresh air.
PIEZO IGNITION SYSTEM
This fireplace insert has a piezo ignitor. This sys-
tem requires no matches, batteries, or other sources
to light fireplace insert.
BLOWER ASSEMBLY
This fireplace insert is equipped with a blower
assembly. The blower operates thermostatically
and has a variable control. The blower circulates
heated air from the fireplace insert into the room.
Use of blower is optional.
AIR FOR COMBUSTION
AND VENTILATION
WARNING: This heater shall
notbeinstalledinaconfinedspace
or unusually tight construction
unless provisions are provided
foradequatecombustionandven-
tilation air. Read the following in-
structions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
Today’s homes are built more energy efficient than
ever. New materials, increased insulation, and new
construction methods help reduce heat loss in
homes. Home owners weather strip and caulk
around windows and doors to keep the cold air out
and the warm air in. During heating months, home
owners want their homes as airtight as possible.
While it is good to make your home energy effi-
cient, your home needs to breathe. Fresh air must
enter your home. All fuel-burning appliances need
fresh air for proper combustion and ventilation.
Exhaust fans, fireplaces, clothes dryers, and fuel
burning appliances draw air from the house to
operate. You must provide adequate fresh air for
these appliances. This will insure proper venting
of vented fuel-burning appliances.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National Fuel
Gas Code ANSI Z223.1/NFPA 54, Section 5.3, Air
for Combustion and Ventilation.
All spaces in homes fall into one of the three fol-
lowing ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 6 through 8 will help
you classify your space and provide adequate ven-
tilation.
Unusually Tight Construction
The air that leaks around doors and windows may
provide enough fresh air for combustion and ven-
tilation. However, in buildings of unusually tight
construction, you must provide additional fresh air.
Unusually tight construction is defined as con-
struction where:
a. walls and ceilings exposed to the out-
side atmosphere have a continuous
water vapor retarder with a rating of
one perm (6 x 10-11 kg per pa-sec-m2)
or less with openings gasketed or
sealed and
b. weather stripping has been added on
openable windows and doors and
c. caulking or sealants are applied to ar-
eas such as joints around window and
door frames, between sole plates and
floors, between wall-ceiling joints, be-
tween wall panels, at penetrations for
plumbing, electrical, and gas lines, and
at other openings.
If your home meets all of the three criteria
above, you must provide additional fresh
air. See Ventilation Air From Outdoors ,
page 8 .
If your home does not meet all of the three
criteria above, proceed to Determining
Fresh-Air Flow for Heater Location , page 7.

113195-01A 7
Confined and Unconfined Space
The National Fuel Gas Code ANSI Z223.1/NFPA
54 defines a confined space as a space whose vol-
ume is less than 50 cubic feet per 1,000 Btu per
hour (4.8 m3per kw) of the aggregate input rating
of all appliances installed in that space and an un-
confined space as a space whose volume is not less
than 50 cubic feet per 1,000 Btu per hour (4.8 m3
per kw) of the aggregate input rating of all appli-
ances installed in that space. Rooms communicat-
ing directly with the space in which the appliances
are installed*, through openings not furnished with
doors, are considered a part of the unconfined space.
*Adjoining rooms are communicating only if there
are doorless passageways or ventilation grills be-
tween them.
DETERMINING FRESH-AIR FLOW
FOR HEATER LOCATION
Determining if You Have a Confined or
Unconfined Space
Use this work sheet to determine if you have a
confined or unconfined space.
Space: Includes the room in which you will install
fireplace plus any adjoining rooms with doorless pas-
sageways or ventilation grills between the rooms.
1. Determine the volume of the space (length x
width x height).
Length x Width x Height =__________cu. ft.
(volume of space)
Example: Space size 22 ft. (length) x 18 ft.
(width) x 8 ft. (ceiling height) = 3168 cu. ft. (vol-
ume of space)
If additional ventilation to adjoining room is sup-
plied with grills or openings, add the volume of
these rooms to the total volume of the space.
2. Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
__________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example: 3168 cu. ft. (volume of space) x 20 =
63,360 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in
the space.
Vent-free fireplace __________ Btu/Hr
Gas water heater* __________ Btu/Hr
Gas furnace __________ Btu/Hr
Vented gas heater __________ Btu/Hr
Gas fireplace logs __________ Btu/Hr
Other gas appliances* + __________ Btu/Hr
Total = __________ Btu/Hr
AIR FOR COMBUSTION
AND VENTILATION
Continued
* Do not include direct-vent gas appliances. Di-
rect-vent draws combustion air from the outdoors
and vents to the outdoors.
Example:
Gas water heater _________ Btu/Hr
Vent-free fireplace + _________ Btu/Hr
Total = _________ Btu/Hr
4. Compare the maximum Btu/Hr the space can
support with the actual amount of Btu/Hr used.
________ Btu/Hr (maximum the space can support)
________ Btu/Hr (actual amount of Btu/Hr used)
Example: 63,360 Btu/Hr (maximum the space
can support)
73,000 Btu/Hr (actual amount of
Btu/Hr used)
The space in the above example is a confined space
because the actual Btu/Hr used is more than the maxi-
mum Btu/Hr the space can support. You must pro-
vide additional fresh air. Your options are as follows:
A. Rework worksheet, adding the space of an adjoin-
ing room. If the extra space provides an uncon-
fined space, remove door to adjoining room or add
ventilation grills between rooms. See Ventilation
Air From Inside Building, page 8.
B. Vent room directly to the outdoors. See Ventila-
tion Air From Outdoors, page 8.
C. Install a lower Btu/Hr fireplace, if lower Btu/Hr
size makes room unconfined.
If the actual Btu/Hr used is less than the maximum
Btu/Hr the space can support, the space is an uncon-
fined space. You will need no additional fresh air ven-
tilation.
WARNING: If the area in
which the fireplace may be op-
erated is smaller than that de-
fined as an unconfined space or
if the building is of unusually
tight construction, provide ad-
equate combustion and ventila-
tion air by one of the methods
described in the National Fuel
Gas Code, ANSI Z223.1/NFPA
54 Section 5.3 or applicable lo-
cal codes .

AIR FOR COMBUSTION
AND VENTILATION
Continued
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills
or ducts. You must provide two permanent open-
ings: one within 12" of the ceiling and one within
12" of the floor. Connect these items directly to
the outdoors or spaces open to the outdoors. These
spaces include attics and crawl spaces. Follow the
National Fuel Gas Code ANSI Z223.1/NFPA 54,
Section 5.3, Air for Combustion and Ventilation
for required size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for inlet
or outlet air into attic if attic has a thermostat-con-
trolled power vent. Heated air entering the attic
will activate the power vent. Any outside air ducts
and/or ash dumps in the fireplace shall be perma-
nently closed at the time of appliance installation.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining un-
confined space. When ventilating to an adjoining
unconfined space, you must provide two perma-
nent openings: one within 12" of the ceiling and
one within 12" of the floor on the wall connecting
the two spaces (see options 1 and 2, Figure 3).
You can also remove door into adjoining room (see
option 3, Figure 3). Follow the National Fuel Gas
Code ANSI Z223.1/NFPA 54, Section 5.3, Air for
Combustion and Ventilation for required size of
ventilation grills or ducts.

INSTALLING GAS PIPING TO
FIREPLACE LOCATION
WARNING: A qualified ser-
vice person must connect fire-
place Insert to gas supply. Fol-
low all local codes.
CAUTION: Never connect
propane/LP heater directly to the
propane/LP supply. This heater
requires an external regulator
(not supplied). Install the exter-
nal regulator between the heater
and propane/LP supply.
WARNING: Never connect
natural gas fireplace insert to
private (non-utility) gas wells.
This gas is commonly known as
wellhead gas.
Installation Items Needed
Before installing fireplace insert, make sure you
have the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas connector
(if allowed by local codes) (not provided)
* A CSA design-certified equipment shutoff valve
with 1/8" NPT tap is an acceptable alternative to
test gauge connection. Purchase the optional CSA
design-certified equipment shutoff valve from your
dealer. See Accessories, page 34.
For propane/LP units, the installer must supply an
external regulator. The external regulator will re-
duce incoming gas pressure. You must reduce in-
coming gas pressure to between 11 and 14 inches
of water. If you do not reduce incoming gas pres-
sure, heater regulator damage could occur. Install
external regulator with the vent pointing down as
shown in Figure 13, page 13. Pointing the vent
down protects it from freezing rain or sleet.

INSTALLATION
Continued
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of
1/2" diameter or greater to allow
proper gas volume to fireplace
insert. If pipe is too small, undue
loss of volume will occur.
Installation must include an equipment shutoff
valve, and plugged 1/8" NPT tap. Locate NPT tap
within reach for test gauge hook up. NPT tap must
be upstream from fireplace insert (see Figure 14).
IMPORTANT: Install equipment shutoff valve in
an accessible location. The equipment shutoff
valve is for turning on or shutting off the gas to
the appliance.
Check your building codes for any special require-
ments for locating equipment shutoff valve to fire-
places.
Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant from go-
ing into pipe. Excess sealant in pipe could result
in clogged fireplace valves.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
We recommend that you install a sediment trap in
supply line as shown in Figure 14. Locate sedi-
ment trap where it is within reach for cleaning.
Install in piping system between fuel supply and
heater. Locate sediment trap where trapped mat-

ter is not likely to freeze. A sediment trap traps
moisture and contaminants. This keeps them from
going into fireplace insert gas controls. If sedi-
