OPERATION
This heater is clean burning. It requires no
outside venting. There is no heat loss out a
vent or up a chimney. Heat is generated by
realistic, dancing yellow ames. This heater
is designed for vent-free operation with ue
damper closed. It has been tested and approved to ANSI Z21.11.2 standard for unvented heaters. State and local codes in some
areas prohibit the use of vent-free heaters.
Non-thermostat models may also be operated
as a vented decorative (ANSI Z21.60) product
by opening ue damper.
SAFETY PILOT
This heater 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 shuts off the
heater if there is not enough fresh air.
WARNING: This heater shall
not be installed in a room or space
unless 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 insure proper
fresh air for this and other fuelburning appliances in your home.
Today’s homes are built more energy efcient
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. Dur-
ing heating months, home owners want their
homes as airtight as possible.
While it is good to make your home energy
efcient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning appliances need fresh air for proper combustion
and ventilation.
State of Massachusetts: The installation must be made by a licensed plumber
or gas fitter in the Commonwealth of
Massachusetts.
Sellers of unvented propane or natural
gas-red supplemental room heaters shall
provide to each purchaser a copy of 527
CMR 30 upon sale of the unit.
Vent-free gas products are prohibited for
bedroom and bathroom installation in the
Commonwealth of Massachusetts.

126842-01A6
Exhaust fans, replaces, 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, Air for
Combustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 5 through 7 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 dened 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 (6x10
-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 oors, between wall-ceiling joints,
between 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 7.
If your home does not meet all of the three
criteria above, proceed to Determining
Fresh-Air Flow For Heater Location.
Conned Space and Unconned Space
The National Fuel Gas Code ANSI Z223.1/
NFPA 54 denes a conned 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 ag-
AIR FOR COMBUSTION AND VENTILATION
Continued
gregate input rating of all appliances installed
in that space and an unconned 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 communicating
directly with the space in which the appliances
are installed*, through openings not furnished
with doors, are considered a part of the unconned space.
* 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 Conned or
Unconned Space
Use this work sheet to determine if you have
a conned or unconned space.
Space: Includes the room in which you will install
replace 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 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 replace _________ Btu/Hr
Gas water heater* _________ Btu/Hr
Gas furnace _________ Btu/Hr
Vented gas heater _________ Btu/Hr
Gas replace 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:
Page 7
www.SuperiorFireplaces.US.com
126842-01A 7
Gas water heater _________ Btu/Hr
Vent-free replace _________ 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)
71,500 Btu/Hr (actual amount of
Btu/Hr used)
The space in the example is a conned 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
adjoining room. If the extra space provides an
unconned space, remove door to adjoining
room or add ventilation grills between rooms.
See Ventilation Air From Inside Building,
page 7.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors, page 7.
C. Install a lower Btu/Hr replace, if lower Btu/
Hr size makes room unconned.
If the actual Btu/Hr used is less than the maxi-
mum Btu/Hr the space can support, the space is
an unconned 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 National Fuel
Gas Code, ANSI Z223.1/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
unconned space. When ventilating to an
adjoining unconned space, you must provide
two permanent openings: one within 12" of the
ceiling and one within 12" of the oor on the

Ventilation Air From Outdoors
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 oor. 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.

ACCESSORY FOR VENTED
OPERATION
Note: When used as a vented heater, appliance must be installed only in a solid-fuel
burning replace with a working ue and constructed of noncombustible material.
You may use this heater as a vented product.
There are three reasons for operating your
heater in the vented mode.
1. The replace does not meet the clearance to combustibles requirements for
vent-free operation.
2. State or local codes do not permit ventfree operation.
3. You prefer vented operation.
If reasons number 1 or 2 apply to you, you
must permanently open chimney ue damper.
You must install the damper clamp accessory
(to order, see Accessories, page 31). This
will insure 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 ue
opening you must provide. Attach damper
clamp so the minimum permanent ue opening will be maintained at all times.

WARNING: If installing in a
sunken replace, special care
is needed. You must raise the
replace oor to allow access to
heater control panel. This will in-
sure adequate air ow and guard
against sooting and controls
being damaged. Raise replace
oor with noncombustible mate-
rial. Make sure material is secure.
CAUTION: Do not pick up
heater base assembly by the
burner. This could damage heat-
er. Only handle base assembly
by grates.
IMPORTANT: Make sure heater burners are
level. If heater is not level, heater will not
work properly.
Installation Items Needed
• hardware package (provided with heater)
• approved exible gas hose (if allowed by
local codes)
•
sealant (resistant to propane/LP gas, not
provided)
• electric drill with 3/16" drill bit
• athead screwdriver
1. Apply pipe joint sealant lightly to male
threads of the tting to be threaded into
gas regulator. Connect approved exible
gas hose to gas regulator of heater (see
Figure 11).
IMPORTANT: Hold gas regulator with
wrench when connecting exible gas hose.
2. Locate masonry screws in hardware
package.
3. Position heater base assembly in replace.
4. Place log in proper position on heater base

CONNECTING TO GAS SUPPLY
WARNING: This appliance
requires a 1/2" NPT (National
Pipe Thread) inlet connection to
the pressure regulator.
WARNING: A qualified
service person must connect
heater to gas supply. Follow
all local codes.
CAUTION: Never connect
propane/LP heater directly to the
propane/LP supply. Propane/LP
heaters require an external regulator (not supplied). Install the
external regulator between the
heater and propane/LP supply.
WARNING: For natural gas
units, never connect heater to
private (non-utility) gas wells.
This gas is commonly known
as wellhead gas.
Installation Items Needed
Before installing heater, 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
* A 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 gas, the installer must supply
an external regulator. An 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 regulator damage could
occur. Install external regulator with vent pointing down as shown in Figure 13. Pointing 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.
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 heater (see
Figure 14 page 14).
IMPORTANT: Install equipment shutoff valve
in an accessible location. Main gas valve is for
turning on or shutting off gas to the appliance.
Check your building codes for any special
requirements for locating equipment shutoff
valve to replaces.
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 heater valves.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.

We recommend that you install sediment
trap in supply line as shown in Figure 14.
Locate sediment trap where it is within reach
for cleaning. Install in piping system between
fuel supply and heater. Locate sediment trap
where trapped matter is not likely to freeze.
A sediment trap traps moisture and contaminants. This keeps them from going into heater
controls. If sediment trap is not installed or is
installed wrong, heater may not run properly.
CAUTION: Avoid damage to
regulator. Hold gas regulator with
wrench when connecting it to gas
piping and/or ttings.

INSPECTING BURNERS
Figure 24 - Correct Pilot Flame Pattern
Figure 25 - Incorrect Pilot Flame Pattern
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes
in the tting at the entrance to the burner.
These holes may become blocked with dust
or lint. Periodically inspect these holes for any
blockage and clean as necessary. Blocked air
holes will create soot.
MAIN BURNER
Periodically inspect all burner ame holes with
the heater running. All slotted burner ame
holes should be open with yellow ame present. All round burner ame holes should be
open with a small blue ame present. Some
burner ame holes may become blocked by
debris or rust, with no ame present. If so,
turn off heater and let cool. Remove blockage,
blocked burner ame holes will create soot.
Check pilot ame pattern and burner ame
patterns often.
PILOT FLAME PATTERN
Figure 24 shows a correct pilot ame pattern.
Figure 25 shows an incorrect pilot ame pattern. The incorrect pilot ame is not touching the
thermocouple. This will cause the thermocouple
to cool. When the thermocouple cools, the
heater will shut down.
If pilot ame pattern is incorrect, as shown
in Figure 25
• turn heater off (see To Turn Off Gas to Appliance, page 19)
• see Troubleshooting, page 22
Note: The pilot ame on natural gas units will
have a slight curve, but ame should be blue
and have no yellow or orange color.

CLEANING AND MAINTENANCE
WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep
control areas, burner and circulating air passageways of heater
clean. Inspect these areas of
heater before each use. Have
heater inspected yearly by a
qualied service person. Heater
may need more frequent clean-
ing due to excessive lint from
carpeting, bedding material, pet
hair, etc.
WARNING: Failure to keep
the primary air opening(s) of
the burner(s) clean may result
in sooting and property damage.
ODS/PILOT AND BURNER
Use a vacuum cleaner or small, soft bristled
brush to clean.
BURNER ORIFICE HOLDER AND
PILOT AIR INLET HOLE
The primary air inlet holes allow the proper
amount of air to mix with the gas. This pro-
vides a clean burning ame. Keep these holes
clear of dust, dirt and lint. 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 qualied service person.
Page 20
www.SuperiorFireplaces.US.com
126842-01A20
We also recommend that you keep the burner
tube 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. If using compressed air in a can, please
follow the directions on the can. If you don’t
follow directions on the can, you could damage the pilot assembly.
1. Shut off unit, including pilot. Allow unit to
cool for at least thirty minutes.
2. Inspect burner, pilot and primary air inlet
holes on orice holder for dust and dirt
(see Figure 26).
3. Blow air through the ports/slots and holes
in the burner.
4. Check orice holder located at the end of
the burner tube again. Remove any large
particles of dust, dirt, lint or pet hair with
