OPERATION
This appliance 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 coals. This appliance is designed for
vent-free operation with flue damper closed. It has
been tested and approved to the ANSI Z21.11.2
standard for unvented room heaters. State and local
codes in some areas prohibit the use of unvented
appliances. This appliance may also be operated
as a vented decorative (ANSI Z21.60) product by
opening the flue damper.
PRODUCT FEATURES
SAFETY DEVICE
This appliance has a pilot with an Oxygen Depletion
Sensing (ODS) safety shutoff system. The ODS/
pilot is a required feature for unvented appliances.
The ODS/pilot shuts off the appliance if there is not
enough fresh air.
ELECTRONIC IGNITION SYSTEM
This appliance has an electronic igniter to light
appliance fuel supply.
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. That 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
following 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
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.
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 open-
able 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, Page 7.
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 con-
fined or unconfined space. The standard method
defines a confined space as a space whose volume
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

* Do not include direct-vent gas appliances. Direct-
vent draws combustion air from the outdoors and

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 (actual amount used)
Example: 51,200 Btu/Hr (maximum the space

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
maximum Btu/Hr the space can support. You must
provide 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 Ventilation
Air From Outdoors, Page 8.
C. Install a lower Btu/Hr appliance, 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 unconfined
space. You will need no additional fresh air ventilation.

ances installed in that space and an unconfined
space as a space whose volume is not less than
50 cubic feet per 1,000 Btu/hr (4.8 m
3
per 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
HEATER LOCATION
Determining if You Have a Confined or
Unconfined Space Using the Standard Method
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) = 2560 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: 2560 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.
WARNING: If the area in which
the appliance 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 National Fuel Gas Code, ANSI
Z223.1/NFPA 54, the International
Fuel Gas Code, or applicable local
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, 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-
controlled power vent. Heated air entering the attic
will activate the power vent.

INSTALLING DAMPER CLAMP ACCESSORY
FOR VENTED OPERATION
NOTE: When used as a vented appliance, appli-
ance must be installed only in a solid-fuel-burning
fireplace with a working flue and constructed of
noncombustible material.
For Massachusetts Residents Only: Installation
of this gas log set as a vented appliance in the
Commonwealth of Massachusetts requires the
damper be permanently removed or welded in the
fully open position.
If your appliance is a manually-controlled model,
you may use this appliance as a vented product.
There are three reasons for operating your appli-
ance in the vented mode.
1. The fireplace does not meet the clearance to
combustibles requirements for vent-free opera-
tion.
2. State or local codes do not permit vent-free
operation.
3. You prefer vented operation.
If reasons number 1 or 2 above apply to you, you
must permanently open chimney flue damper. You
must install the damper clamp accessory (to order,
see Accessories, Page 40). This will ensure vented
operation (see Figure 10). The damper clamp will
keep damper open. Installation instructions are
included with clamp accessory.
See chart below for minimum permanent flue
opening you must provide. Attach damper clamp
so the minimum permanent flue opening will be
maintained at all times.

WARNING: You must secure this
heater to fireplace floor. If not, heater
will move when you adjust controls.
Moving heater may cause a gas leak or
log misplacement.
WARNING: If installing in a sunken
fireplace, special care is needed. You
must raise the fireplace floor to allow
access to heater control panel. This
will ensure adequate air flow and guard
against sooting and controls being
damaged. Raise fireplace floor with
noncombustible material. Make sure
material is secure.
CAUTION: Do not pick up heater
base assembly by burners. This could
damage heater. Only handle base as-
sembly by grates.
IMPORTANT:Make sure the heater burners are
level. If appliance is not level, appliance will not

CONNECTING TO GAS SUPPLY
WARNING: This appliance re-
quires a 3/8" NPT (National Pipe
Thread) inlet connection to the pres-
sure regulator.
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.

SuperiorFireplaces.us.com 900463-01E14
Installation Items Needed
Before installing appliance, 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)
* An equipment shutoff valve with 1/8" NPT tap is
an acceptable alternative to test gauge connection.
Purchase the optional equipment shutoff valve from
your dealer.
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, appli-
ance regulator damage could occur. Install external
regulator with the vent pointing down as shown in
Figure 13. Pointing the vent down protects it from
freezing rain or sleet.

We recommend that you install a sediment trap in
supply line as shown in Figure 14, Page 14. Locate
sediment trap where it is within reach for cleaning.
Install in piping system between fuel supply and
appliance. Locate sediment trap where trapped
matter is not likely to freeze. A sediment trap traps
moisture and contaminants. This keeps them from
going into appliance controls. If sediment trap is
not installed or is installed wrong, appliance may
not run properly.
WARNING: Use pipe joint sealant
that is resistant to liquid petroleum
(LP) gas.
CAUTION: Use only new, black iron
or steel pipe. Internally-tinned copper
tubing may be used in certain areas.
Checkyourlocalcodes.Usepipeof1/2"
diameter or greater to allow proper gas
volume to heater. If pipe is too small,
undue loss of volume will occur.
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 appliance (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
appliances.
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
appliance valves.
