Todayʼs 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.
PRODUCT FEATURES
OPERATION
This vent-free fireplace 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
optional blower, the fireplace requires no electricity
making it ideal for emergency backup heat.
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.
SAFETY DEVICE
This fireplace has a pilot with an Oxygen Depletion
Sensing (ODS) safety shutoff system. The ODS/
pilot is a required feature for vent-free room heat-
ers. The ODS/pilot system shuts off the fireplace
if there is not enough fresh air.

Confined Space and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/NFPA
54 defines a confined space as a space whose
volume is less than 50 cubic feet per 1,000 Btu
per hour (4.8 m3 per kw) of the aggregate input
rating of all appliances installed in that space and
an unconfined 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 appliances installed in that space. Rooms com-
municating directly with the space in which the
appliances are installed*, through openings not
furnished with doors, are considered a part of the
unconfined space.
AIR FOR COMBUSTION
AND VENTILATION
Continued
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
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation grills
between them.
3. Confined Space
The information on pages 5 through 7 will help
you classify your space and provide adequate
ventilation.
DETERMINING FRESH-AIR FLOW
FOR HEATER LOCATION
Unusually Tight Construction
The air that leaks around doors and windows
may provide enough fresh air for combustion and
ventilation. However, in buildings of unusually
tight construction, you must provide additional
fresh air.
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.
Unusually tight construction is defined as
construction 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
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 20 ft. (length) x 18 ft.
(width) x 8 ft. (ceiling height) = 2880 cu. ft.
(volume of space)
b. weather stripping has been added on
openable windows and doors and
If additional ventilation to adjoining room is
supplied with grills or openings, add the volume
of these rooms to the total volume of the space.
c. caulking or sealants are applied to
areas such as joints around window
and door frames, between sole plates 2. Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
and floors, between wall-ceiling joints,
between wall panels, at penetrations
for plumbing, electrical, and gas lines,
and at other openings.
__________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example: 2880 cu. ft. (volume of space) x 20 =
57,600 (maximum Btu/Hr the space can support)
If your home meets all of the three criteria
above, you must provide additional fresh
air. See Ventilation Air From Outdoors,
page 7.

VENTILATION AIR
AIR FOR COMBUSTION
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.

Ventilation Air From Outdoors
If the actual Btu/Hr used is less than the maximum
Btu/Hr the space can support, the space is an un-
confined space. You will need no additional fresh
air ventilation.
Provide extra fresh air by using ventilation grills or
ducts. You must provide two permanent openings:
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.
WARNING: If the area in
which the heater may be oper-
ated is smaller than that defined
as an unconfined space or if the
building is of unusually tight
construction, provide adequate
combustion and ventilation air
byoneofthemethodsdescribed
in the National Fuel Gas Code,
ANSIZ223.1/NFPA54Section5.3
or applicable local codes.
IMPORTANT: Do not provide openings for inlet
or outlet air into attic if attic has a thermostat-
controlled power vent. Heated air entering the attic
will activate the power vent.

RELOCATING WALL SWITCH
ASSEMBLY
INSTALLATION
Continued
Note: The decorative wall switch plate supplied
is white. The wall switch plate may be painted to
match your decor.
ELECTRICAL CONNECTIONS FOR
POWER CORD
This fireplace operates on 120 VAC, 60 Hz
power. An electrical power cord is supplied with
this unit.
The push-button switch and decorative wall
plate assembly supplied with your fireplace is
pre-mounted at the factory in the lower cavity of
the fireplace. You may relocate this wall switch
assembly to a more convenient location such as the
side of your mantel or directly onto the wall near
the fireplace. To mount the wall switch assembly,
you must first cut openings in the mantel or wall
where the switch will be located.
For Mantel Installation
1. Determine from which side of the fireplace the
power cord will exit. Locate the 1.5" diameter
hole near the center of floor support bracket on
appropriate side of lower cavity (see Figure 7).
2. Locate power cord. Remove wire tie or tape
holding plug end of power cord.
Note: If you choose to relocate the wall switch as-
sembly, do so before final installation into a mantel
or recessing into a wall. If you are installing an
optional blower accessory, install it at the same
time you relocate the wall switch assembly.
3. Power cord has 2 plastic hole bushings
threaded onto it. Route cordʼs 3-prong plug
through the 1.5" diameter hole in appropriate
floor support bracket.
4. Push first plastic bushing completely through
hole. Squeeze bushing as needed to do this.
CAUTION: The wall switch
assemblymustneverbemount-
ed directly above the fireplace
whereheatmaydamageit.Ifyou
relocate wall switch assembly
from lower fireplace cavity, it
must be mounted either on side
wall of mantel or on wall to side
of fireplace.
5. Install the second plastic bushing into the
hole in the floor support bracket by snapping
into place.
6. Route the 3-prong plug through the 1.5" hole
in fireplace outer casing.
7. Install the first plastic bushing into this hole
by snapping into place.
8. After you have connected to gas supply and
checked your gas connections (see pages 14 and
15), plug power cord into any convenient 3-
prong grounded wall receptacle near fireplace.
For Recessed Installation
If fireplace is to be recessed into a wall (see
Built-In Fireplace Installation, page 17), we
recommend mounting wall switch assembly to
left side of fireplace. The wall switch assembly
should be mounted approximately 12" from left
edge of fireplace, and less than 60" from the floor.
IMPORTANT:Do not locate wall switch assembly
directly in front of wall stud - there must be room
behind wall board for wires from switch. If you
choose to locate wall switch assembly to right side
of fireplace, the length of the cord restricts you to
less than 6" from right edge of fireplace and less
than 48" from floor.

wall switch assembly may be mounted on either
side of the mantel, facing to the side. Do not locate
wall switch assembly anywhere on the front face
of the mantel.
If you are mounting wall switch assembly to a
wall, continue reading. If you are mounting your
wall switch assembly to the side of the mantel,
see page 12.
CAUTION: Do not apply ex-
cessive pull on cord.
CAUTION: Be careful of gas
lines and wiring when moving
floor.
Mounting Wall Switch Assembly to Wall
for Recessed Fireplace
7. Create three openings on wall according to
Template 1, page 39. This is best done by
making a pattern to work with on your wall.
Carefully cut page 39 from manual and tape
paper template vertically onto wall at pre-
ferred location. Pierce the paper at the centers
of the 2 holes with a nail or sharp pencil,
leaving a mark on the wall. Do the same at
centers of the four circles near the corners of
the rectangle.
1. Determine the new location for the wall switch
assembly. The wires attached to switch are six
feet long.
2. Remove 2 screws securing plastic wall switch
assembly to bracket in fireplace lower cavity.
Save screws.
3. Remove wire tie holding coiled wire attached
to wall switch assembly (see Figure 8).
4. Remove wall switch assembly from bracket.
5. Carefully pass wall switch assembly and cord
through large elongated hole in rear of either
left or right floor support bracket, depending on
desired location of switch. Pass wall switch as-
sembly and cord through 1.5" diameter hole in
side of fireplace outer casing (see Figure 9).
8. Remove paper template from wall.
9. Drill 3/8" holes at each mark.
10. Using a straight edge and pencil, connect the
outer edges of the 4 holes for the rectangle (see
Figure 10). This will give you cutting lines for
the rectangle you will cut in the wall.

For propane/LP units, the installer must supply
an external regulator. The external regulator will
reduce incoming gas pressure. You must reduce
incoming 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 14. Pointing the vent down
protects it from freezing rain or sleet.

INSTALLING GAS PIPING TO
FIREPLACE LOCATION
WARNING: A qualified
service person must connect
fireplace to gas supply. Follow
all local codes.
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.
If pipe is too small, undue loss
of volume will occur.
WARNING: For propane/LP
units, never connect fireplace
directly to propane/LP supply.
This fireplace requires an ex-
ternal regulator (not supplied).
Install the external regulator
between the heater and pro-
pane/LP supply.
Installationmustincludeanequipmentshutoffvalve,
union, and plugged 1/8" NPT tap. Locate NPT tap
within reach for test gauge hook up. NPT tap must
be upstream from fireplace (see Figure 14).
WARNING: For natural gas
units, never connect fireplace
toprivate(non-utility)gaswells.
This gas is commonly known as
wellhead gas.
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.

2. Route gas line (provided by installer) from
equipment shutoff valve to fireplace. Route
flexible gas supply line through one of the
access holes.
We recommend that you install a sediment trap in
supply line as shown in Figure 15. Locate sediment
trap where it is within reach for cleaning. Install in
piping system between fuel supply and fireplace.
Locate sediment trap where trapped matter is not
likely to freeze. A sediment trap traps moisture and
contaminants. This keeps them from going into fire-
place gas controls. If sediment trap is not installed or
is installed wrong, fireplace may not run properly.
NOTICE: Most building codes
do not permit concealed gas
connections. A flexible gas line
is provided to allow accessibility
fromthefireplace(seeFigure16).
The flexible gas supply line con-
nection to the equipment shutoff
valve should be accessible.

a qualified service person or gas supplier
for repairs. Until repairs are made, light
and operate manually (see Manual Lighting
Instructions for Electrical Power Outage).
1. Follow steps 1 through 3 under Normal
Lighting Instructions, page 22.
2. Set manual ignition bypass switch on con-
trol panel to ON position (manual ignition
position). See Figure 39.
3. The pilot is attached to the rear of the front
burner. You will be able to see the pilot
and spark electrode without removing the
screen or logs.
4. When pilot flame is lit, the thermocouple is
heated by the flame. When thermocouple
becomes hot (5 to 15 seconds), main burner
will automatically light on high flame.
4. Place the magnetic manual override handle,
provided with this unit, on the end of the
gas valve stem (see Figure 39).
5. To lower flame, point remote control
toward lower front of fireplace and push
HI/LO button once.
5. Turn the override handle fully counterclock-
wise
tothePILOTposition.Thehandle
will not stop but will begin to slip when you
have fully turned to the PILOT position.
Note: This fireplace does not have a pilot-
only mode.
6. While holding the valve handle in the
PILOT position, press and release piezo
ignitorbutton (see Figure 39). This will light
the pilot. If needed, keep pressing ignitor
button until pilot lights.

BURNER FLAME PATTERNS
WARNING: Turn off heater
and let cool before cleaning.
Figure 43 shows correct front and/or middle burner
flame patterns. Figure 44 shows incorrect front
and/or middle burner flame patterns. The incorrect
burner flame patterns show yellow tipping at top
of blue flame.
CAUTION: You must keep
control areas, burners, and
circulating air passageways
of heater clean. Inspect these
areas of heater before each use.
Have heater inspected yearly
by a qualified service person.
Heater may need more frequent
cleaning due to excessive lint
fromcarpeting,pethair,bedding
material, etc.
WARNING: If yellow tipping
occurs, your heater could pro-
duce increased levels of carbon
monoxide. If burner flame pat-
ternsshowyellowtipping,follow
instructionsbelow.Yellowflame
on rear burner is normal.
NOTICE: Do not mistake orange
flames with yellow tipping. Dirt
orotherfineparticlesareburned
byheater, causingbriefpatches
of orange flame.
WARNING: Failure to keep
the primary air opening(s) of
theburner(s)cleanmayresultin
sooting and property damage.
If front and/or middle burner flame patterns are
incorrect, as shown in Figure 44
BURNER INJECTOR HOLDERS AND
PILOT AIR INLET HOLES
•
turn heater off (see To Turn Off Gas to Appli-
ance, page 23
The primary air inlet holes allow the proper amount
of air to mix with the gas. This provides a clean
burning flame. Keep these holes clear of dust, dirt,
lint, and pet hair. Clean these air inlet holes prior to
each heating season. Blocked air holes will create
soot. We recommend that you clean the unit every
three months during operation and have heater
inspected yearly by a qualified service person.
•
see Troubleshooting, page 27
We also recommend that you keep the burner
tubes and pilot assembly clean and free of dust
and dirt. To clean these parts we recommend using
compressed air no greater than 30 PSI. Your local
computer store, hardware store, or home center
may carry compressed air in a can. You can use a
vacuum cleaner in the blow position. If using com-
pressed air in a can, please follow the directions on
the can. If you donʼt follow directions on the can,
you could damage the pilot assembly.
Figure 43 - Correct Burner Flame
Patterns
Yellow Tipping At Top
of Blue Flame
1. Shut off the unit, including the pilot. Allow
the unit to cool for at least thirty minutes.
2. Inspect burners, pilot, and primary air inlet
holes on injector holder for dust and dirt (see
Figures 45 and 46, page 26).

6. In case any large clumps of dust have now been
pushed into the burner repeat steps 3 and 4.
Clean the pilot assembly also. A yellow tip on the
pilot flame indicates dust and dirt in the pilot as-
sembly. There is a small pilot air inlet hole about
two inches from where the pilot flame comes out
of the pilot assembly (see Figure 47). With the unit
off, lightly blow air through the air inlet hole. The
access hole for propane/LP pilot is on the front of
the burner carriange as shown in Figure 47. The ac-
cess hole for natural pilot is behind the pilot bracket
on the top of burner carriage (see Figure 47). You
may blow through a drinking straw if compressed
air is not available.
