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 gen-
erated 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
This fireplace includes a blower assembly. The
blower operates thermostatically and features
a variable speed control. The blower circulates
heated air from the fireplace into the room.

SuperiorFireplaces.us.com
900719-00C 7
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
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 9.
Ifyourhome doesnotmeet 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 m3per kw) of the ag-
gregate 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 ag-
gregate 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, homeowners 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 ap-
pliances 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 NationalFuel
Gas Code, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on Pages 7–9 will help you
classify 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 un-
usually 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
properfreshair for this and other fuel-
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 door-
less 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 supplied 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: 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
support)
_______ 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:

B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors Page 9.
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 maxi-
mum Btu/Hr the space can support, the space is
an unconfined 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
NationalFuel Gas Code,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
unconfined 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
1and2,Figure 3). You can also remove door
into adjoining room (see option 3, Figure 3).

WARNING: Never connect
natural gas fireplace to private
(non-utility) gas wells. This
gas is commonly known as
wellhead gas.
Installation Items Needed
Before installing fireplace, make sure you
have the items listed below.
• external regulator for propane/LP unit only
(supplied 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 connec-
tor (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 regula-
tor damage could occur. Install external regu-
lator 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. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of
1/2"diameterorgreatertoallow
proper gas volume to fireplace.
If pipe is too small, undue loss
of volume will occur.
Mantel Clearances for Built-In
Installation
If placing mantel above built-in fireplace, you
must meet minimum clearance between man-
tel shelf and top of fireplace opening.
NOTICE:Ifyourinstallationdoes
not meet the minimum clear-
ances shown, you must do one
of the following:
• raise the mantel to an accept-
able height
• remove the mantel
NOTICE: Surface temperatures
of adjacent walls and mantels
become hot during operation.
Walls and mantels above the
firebox may become hot to
the touch. If installed properly,
these temperatures meet the
requirement of the national
product 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
fireplace to gas supply. Follow
all local codes.
CAUTION: Never connect
propane/LP fireplace directly
to the propane/LP supply. This
fireplace requires an external
regulator (not supplied). Install
the external regulator between
the fireplace and propane/LP
supply.

SuperiorFireplaces.us.com
900719-00C 15
Installation must include an equipment shutoff
valve, union, and plugged 1/8" NPT tap. Lo-
cate 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
requirements 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.
WARNING: Use pipe joint
sealantthatisresistanttoliquid
petroleum (LP) gas.
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.
