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
blower, the fireplace requires no electricity making it
ideal for emergency backup heat.
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 heaters. The
ODS/pilot system shuts off the fireplace if there is
not enough fresh air.
ELECTRONIC IGNITION SYSTEM
This heater has an electronic igniter to light the
fireplace's fuel supply.
BLOWER ASSEMBLY
Thisfireplaceincludesablowerassembly.Theblower
operates thermostatically and features a variable
speed control. The blower circulates heated air from
the fireplace into the room.

SuperiorFireplaces.us.com 900719-00D6
Unusually tight construction is defined as con-
struction where:
a. walls and ceilings exposed to the outside
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 areas such
as joints around window and door frames,
between sole plates and floors, between
wall-ceiling joints, between wall panels, at
penetrations for plumbing, electrical, and gas
lines, and at other openings.
If your home meets all three criteria above, you
must provide additional fresh air. See Ventilation
Air From Outdoors, Page 8.
If your home does not meet all three criteria
above, proceed to Determining Fresh-Air Flow For
Heater Location.
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/ NFPA54
allows two methods for determining whether the
space in which the heater is being installed is confined
or unconfined space. The standard method 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 m3per kw) of the aggregate
input rating of all appliances installed in that space.
Rooms communicating directly with the space in
which the appliances are installed*, through openings
not furnished with doors, are considered a part of the
unconfined space.
Where the air infiltration rate of a structure is
known, the Known Air Infiltration Rate Method may
be used. Follow The National Fuel Gas Code, ANSI
Z223.1/NFPA 54 to use this method to determine
if the space is confined or unconfined.
* Adjoining rooms are communicating only if there
are doorless passageways or ventilation grills
between them.
DETERMINING FRESH-AIR FLOW FOR
FIREPLACE LOCATION
Determining if You Have a Confined or
Unconfined Space Using the Standard Method
AIR FOR COMBUSTION AND VENTILATION
Today’s homes are built more energy efficient than
ever. New materials, increased insulation, and new
construction methods help reduce heat loss in
homes. Homeowners apply 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 efficient,
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, some fireplaces, clothes dryers and
some fuel-burning appliances draw air from the
house to operate. You must provide adequate fresh
air for these appliances. This will ensure proper
venting of vented fuel-burning appliances.
PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas
Code, ANSI Z223.1/NFPA 54, 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 6–8 will help you clas-
sify your space and provide adequate ventilation.
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.
WARNING: This heater shall not
be installed in a room or space un-
less the required volume of indoor
combustion air is provided by the
method described in the National
Fuel Gas Code, ANSI Z223.1/NFPA
54, the International Fuel Gas Code,
or applicable local codes. Read the
following instructions to ensure
properfreshairforthisandotherfuel-
burning appliances in your home.

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
passageways 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 20 ft. (length) x 16 ft. (width)
x 8 ft. (ceiling height) = 2,560 cu. ft. (volume 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 = (Maximum
Btu/Hr the space can support)
Example: 2,560 cu. ft. (volume of space) x 20 =
51,200 (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
* Do not include direct-vent gas appliances. Direct-
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 sup-
port)
_________Btu/Hr (actual amount of Btu/Hr used)
Example: 51,200 Btu/Hr (maximum the space
can support)
73,000 Btu/Hr (actual amount of Btu/
Hr used)
The space in the example is a confined space because
the actual Btu/Hr used is more than the maximum Btu/
Hr the space can support. You must provide additional
fresh air. Your options are as follows:

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 un-
confined space. You will need no additional fresh air
ventilation.
WARNING: If the area in which
the heater may be operated does not
meet the required volume for indoor
combustion air, combustion and
ventilation air shall be provided by
one of the methods described in the
NationalFuelGasCode,ANSIZ223.1/
NFPA 54, the International Fuel Gas
Code, or applicable local codes.
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 permanent
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).

standard. Follow all minimum clearances
shown in this manual.
INSTALLING GAS PIPING TO FIREPLACE
LOCATION
WARNING: This appliance
requires a 1/2" NPT (National Pipe
Thread) inlet connection.
WARNING: A qualified service
person must connect appliance to gas
supply. Follow all local codes.
CAUTION:Neverconnectpropane/
LP fireplace directly to the propane/
LP supply. This heater requires an
external regulator (not supplied).
Install the external regulator between
the heater and propane/LP supply.
WARNING: Never connect this
appliance to private (non-utility) gas
wells. This gas is commonly known
as wellhead gas and does not have
odorants and may have impurities, and
variations in BTU content. The use of
well-head gas will void the manufac-
turer’s warranty to this appliance.
Installation Items Needed
Before installing fireplace, make sure you have the
items listed below.
• external regulator for propane/LP unit only (sup-
plied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap (optional)
• tee joint
• pipe wrench
• approved flexible gas line with gas connector (if
allowed by local codes) (not provided)
* A equipment shutoff valve with 1/8" NPT tap is
an acceptable alternative to test gauge connection.
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" of water. If you
do not reduce incoming gas pressure, heater regu-
lator damage could occur. Install external regulator
with the vent pointing down as shown in Figure 17,
Page 15. Pointing the vent down protects it from
freezing rain or sleet.
CAUTION: Use only new, black
iron or steel pipe. Internally-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 heater.
If pipe is too small, undue loss of
volume will occur.

CONNECTING FIREPLACE TO GAS SUPPLY
Installation Items Needed
• 5/16" hex socket wrench or nut-driver
• Phillips screwdriver
• sealant (resistant to propane/LP gas, not pro-
vided)
1. Remove fireplace screen. Remove two screws
that hold fireplace screen in place for shipping.
These screws are located near top of screen.
Discard screws. Push the bottom corners of the
screen in and release. The screen will pop out
at the bottom. Grasp the bottom of the screen,
lift the screen up and pull out to remove.
2. Remove screws that attach log base assembly to
fireplace (see Figure 19, Page 16). Carefully lift
up log base assembly and remove from fireplace
(see Figure 19, Page 16).
3. Route gas line (provided by installer) from
equipment shutoff valve to fireplace. Route
flexible gas supply line through one of the
access holes.
NOTE: If adding brick liner accessory kit, install it
now. Follow brick liner accessory kit instructions.
4. Attach the flexible gas line to gas supply
(see Figure 20, Page 16). Check tightness of
flexible gas line attached to gas regulator of
fireplace (see Figure 20, Page 16).
5. Check all gas connections for leaks. See Check-
ing Gas Connections, Page 16.
WARNING: Use pipe joint sealant
that is resistant to liquid petroleum
(LP) gas.
Installation must include an equipment shutoff
valve, 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 18).
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
fireplaces.
Apply pipe joint sealant lightly to male NPT threads.
This will prevent excess sealant from going into
pipe. Excess sealant in pipe could result in clogged
fireplace valves. Never use sealant on flare threads.
We recommend that you install a sediment trap in
supply line as shown in Figure 18. 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 fireplace gas controls. If sediment trap is not
installed or is installed wrong, fireplace may not
run properly.
