IMPORTANT SAFETY INFORMATION
THIS IS A HEATING APPLIANCE
• An unvented room heater having an input rating of
more than 6,000 Btu per hour shall not be installed in a
bathroom.
• An unvented room heater having an input rating of
more than 10,000 Btu per hour shall not be installed in
a bedroom or bathroom.
• Due to high temperatures, the appliance should be located
out of traffic and away from furniture and draperies.
• Children and adults should be alerted to the hazard of
high surface temperature and should stay away to avoid
burns or clothing ignition.
• Young children should be carefully supervised when they
are in the same room with the appliance.
• Do not place clothing or other flammable material on or
near the appliance.
• Installation and repair should be done by a QUALIFIED
SERVICE PERSON. This appliance should be inspected
before use and at least annually by a professional service
person. More frequent cleaning may be required due to
excessive lint from carpeting, bedding materials, etc. It
is imperative that control compartments, burners and
circulating air passageways of the appliance be kept
clean.
• DO NOT use this fireplace if any part has been under
water. Immediately call a qualified service technician
to inspect the fireplace and to replace any part of the
control system and any gas control which has been under
water.
• You must operate fireplace with fireplace screen closed in
place. Do not close glass doors while operating heater.
• Do not place trash, logs or other articles on the log set
during operation.
• During manufacturing, fabricating and shipping, various
components of this appliance are treated with certain
oils, films or bonding agents. These bonding agents are
not harmful but may produce annoying smoke and
smells as they are burned off during initial operation of
the appliance. This is a normal temporary occurrence.
A window should be opened during the initial bake out
period.
• Correct installation of the ceramic fiber logs, proper
location of the fireplace and annual cleaning are necessary
to avoid potential problems with sooting. Sooting, resulting
from improper installation or operation, can settle on
surfaces outside the fireplace. See instructions for proper
installation.
• WARNING: Do not allow fans to blow directly into
the fireplace. Avoid any drafts that alter burner flame
patterns.
• WARNING: Do not use a blower insert, heat exchanger
insert or other accessory not approved for use with this
heater.
• WARNING! This fireplace needs fresh air for ventilation
to operate properly. This fireplace has an ODS (oxygen
depletion sensor) which will shut off the fireplace if
adequate fresh air is not available.
• Keep appliance area clear and free from combustible
materials, gasoline and other flammable vapors and
liquids.
WARNING
When used without adequate combustion and ventilation air,
heater may give off CARBON MONOXIDE, an odorless,
poisonous gas.
Do not install heater until all necessary provisions are
made for combustion and ventilation air. Consult the written instructions provided with the heater for information
concerning combustion and ventilation air. In the absence
of instructions, refer to the National Fuel Gas Code, ANSI
Z223.1, Section 5.3 or applicable local codes.
This heater is equipped with a PILOT LIGHT SAFETY
SYSTEM designed to turn off the heater if not enough fresh
air is available.
DO NOT TAMPER WITH PILOT LIGHT SAFETY
SYSTEM!
If heater shuts off, do not relight until you provide fresh air.
If heater keeps shutting off, have it serviced. Keep burner and
control compartment clean.
CARBON MONOXIDE POISONING MAY LEAD TO
DEATH.
Early signs of carbon monoxide poisoning resemble the flu,
with headache, dizziness and/or nausea. If you have these signs,
heater may not be working properly. Get fresh air at once!
Have heater serviced.
Some people — pregnant women, persons with heart or lung
disease, anemia, those under the influence of alcohol , those at
high altitudes — are more affected by carbon monoxide than
others.
The pilot light safety system senses the depletion of oxygen at its
location. If this heater is installed in a structure having a high
vertical dimension, the possibility exists that the oxygen supply
at the higher levels will be less than that at the heater. In this type
of application, a fan to circulate the structure air will minimize
this effect. The use of this fan will also improve the comfort level
in the structure. When a fan is used to circulate air, it should be
located so that the air flow is not directed at the burner.

SAFETY INFORMATION FOR USERS OF LP-GAS
Propane (LP-Gas) is a flammable gas which can cause fires
and explosions. In its natural state, propane is odorless and
colorless. You may not know all the following safety precau
tions which can protect both you and your family from an
accident. Read them carefully now, then review them point
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!
• Do not operate electric switches, light matches, use your
phone. Do not do anything that could ignite the gas.
• Get everyone out of the building, vehicle, trailer, or area. Do
that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• LP-Gas is heavier than air and may settle in low areas such
as basements. When you have reason to suspect a gas leak,
keep out of basements and other low areas. Stay out until
firefighters declare them to be safe.
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must find out if you
can smell the odorant in propane. Smoking can decrease your
ability to smell. Being around an odor for a time can affect your
sensitivity or ability to detect that odor. Sometimes other odors
in the area mask the gas odor. People may not smell the gas odor
or their minds are on something else. Thinking about smelling a
gas odor can make it easier to smell.
The odorant in LP-gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the
movement of the gas through soil can filter the odorant. Odorants
in LP-Gas also are subject to oxidation. This fading can occur if
by point with the members of your household. Someday
when there may not be a minute to lose, everyone's safety
will depend on knowing exactly what to do. If, after read
ing the following information, you feel you still need more
information, please contact your gas supplier.
• Use your neighbor's phone and call a trained LP-Gas service
person and the fire department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enter the building, vehicle, trailer, or area.
• Finally, let the service man and firefighters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into
walls, masonry and other materials and fabrics in a room. That
will take some of the odorant out of the gas, reducing its odor
intensity.
LP-Gas may stratify in a closed area, and the odor intensity
could vary at different levels. Since it is heavier than air, there
may be more odor at lower levels. Always be sensitive to the
slightest gas odor. If you detect any odor, treat it as a serious
leak. Immediately go into action as instructed earlier.
-
SOME POINTS TO REMEMBER
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it
to find out what the propane odor smells like. If you suspect
that your LP-Gas has a weak or abnormal odor, call your
LP-Gas Dealer.
• If you are not qualified, do not light pilot lights, perform
service, or make adjustments to appliances on the LP-Gas
system. If you are qualified, consciously think about the
odor of LP-Gas prior to and while lighting pilot lights or
performing service or making adjustments.
• Sometimes a basement or a closed-up house has a musty
smell that can cover up the LP-Gas odor. Do not try to light
pilot lights, perform service, or make adjustments in an area
where the conditions are such that you may not detect the
odor if there has been a leak of LP-Gas.
• Odor fade, due to oxidation by rust or adsorption on walls
of new cylinders and tanks, is possible. Therefore, people
should be particularly alert and careful when new tanks or
cylinders are placed in service. Odor fade can occur in new
tanks, or reinstalled old tanks, if they are filled and allowed
Page 4 23466-0-0407
to set too long before refilling. Cylinders and tanks which
have been out of service for a time may develop internal rust
which will cause odor fade. If such conditions are suspected
to exist, a periodic sniff test of the gas is advisable. If you
have any question about the gas odor, call your
dealer. A periodic sniff test of the LP-gas is a good safety
measure under any condition.
• If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the same
immediate action recommended above for the occasion when
you do detect the odorized LP-Gas.
• If you experience a complete "gas out," (the container is un
der no vapor pressure), turn the tank valve off immediately.
If the container valve is left on, the container may draw in
some air through openings such as pilot light orifices. If this
occurs, some new internal rusting could occur. If the valve is
left open, then treat the container as a new tank. Always be
sure your container is under vapor pressure by turning it off
at the container before it goes completely empty or having
it refilled before it is completely empty.

monoxide poisoning.
Operation
This unvented fireplace requires no outside venting. This unvented
fireplace is designed for vent-free operation with flue damper
closed. State and local codes in some areas prohibit the use of
unvented fireplace.
(A)VFD26F(M,P)3, Millivolt controls
The valve regulator controls the burner pressure which should be
checked at the pressure test point. Turn captured screw counter
clockwise 2 or 3 turns and then place tubing to pressure gauge over
test point (Use test point “A” closest to control knob). After taking
pressure reading, be sure and turn captured screw clockwise firmly
to re-seal. Do not over torque. Check for gas leaks.
Millivolt System, (A)VFD26F(M,P)3
When you ignite the pilot, the thermocouple produces millivolts
(electrical current) which energizes the magnet in the gas valve.
After 30 seconds to 1 minute time period you can release the gas
control knob and the pilot will stay ON. Allow your pilot flame to
operate an additional one (1) to two (2) minutes before you turn the
gas control knob from the PILOT position to the ON position. This
time period allows the millivolts (electrical current) to build-up to
a sufficient level allowing the gas control to operate properly.

WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An unvented room
heater produces approximately one (1) ounce (30ml) of water for
every 1,000 BTU's (.3KW's) of gas input per hour. .
Unvented room heaters are recommended as supplemental heat (a
room) rather than a primary heat source (an entire house). In most
supplemental heat applications, the water vapor does not create a
problem. In most applications, the water vapor enhances the low
humidity atmosphere experienced during cold weather.
Page 8 23466-0-0407
The following steps will help insure that water vapor does not
become a problem.
1. Be sure the heater is sized properly for the application, including
ample combustion air and circulation air.
2. If high humidity is experienced, a dehumidifier may be used to
help lower the water vapor content of the air.
3. Do not use an unvented room heater as the primary heat
source.
PROVISIONS FOR ADEQUATE COMBUSTION & VENTILATION AIR
This heater shall not be installed in a confined space or unusually
tight const ruction unle ss pr ovisions are pro vided for adequa te
combustion and ventilation air.
The National Fuel Gas Code defines a confined space as a space
whose volume is less than 50 cubic feet per 1,000 Btu per hour
3
(4.8m
per kw) of the aggre gate input rating of all appl iances
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 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.
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 construction
where:
a. Walls and ceilings exposed to the outside atmosphere have
a continuous water vapor retarder with a rating of one perm
or less with openings gasketed or sealed, and
b. Weatherstripping 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 of the three criteria above, you must provide
additional fresh air. See “Ventilation Air From Outdoors,”
page 10.
Determining if You Have a Confined or Unconfined Space
Use this worksheet to determine if you have a confined or unconfined
space.
Space: Includes the room in which you will install heater 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 16 ft. (length) x 10 ft. (width) x 8 ft. (ceiling
height) = 1,280 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. Divide the space volume by 50 cubic feet to determine the
maximum BTU/Hr the space can support.
(volume of space) ÷ 50 cu. ft. = (maximum
BTU/Hr the space can support)
Example: 1,280 cu. ft. (volume of space) ÷ 50 cu. ft. = 25.6 or
25,600 (maximum BTU/Hr the space can support)
3. Add the BTU/Hr of all fuel burning appliances in the space.
Vent-free heater
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
Example: Vented gas heater 20,000 BTU/Hr
Vent-free heater + 18,000 BTU/Hr
Total = 38,000 BTU/Hr
*Do not include direct-vent gas appliances. Direct vent draws
combustion air from the outdoors and vents to the outdoors.
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:
25,600 BTU/Hr (maximum the space can support)
38,000 BTU/Hr (actual amount of BTU/Hr used)
Warning: If the area in which the heater may be operated is smaller
than that defined as an unconfined space or if the building is of
unusually tight construction, provide adequate combustion and
ventilation air by one of the methods described in the National Fuel
Gas Code, ANSI Z223.1, Section 5.3 or applicable local codes.
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 adjoining room. If
the extra space provides an unconfined space, remove door to
adjoining room or add ventilation grills between rooms. See
Ventilation Air From Inside Building.
B. Vent room directly to the outdoors. See Ventilation Air From
Outdoors.
C. Install a lower BTU/Hr heater, 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.
WARNING: You must provide additional ventilation air
in a confined space.
BTU/Hr
Page 923466-0-0407
PROVISIONS FOR ADEQUATE COMBUSTION & VENTILATION AIR
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 1 and 2, Figure 5). You can also remove door
into adjoining room (see option 3, Figure 5). Each ventilation grill
or opening shall have a minimum free area of one square inch per
1,000 BTU/HR of the total input rating of the gas equipment in
the confined space.
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 with 12" of the floor. Connect these items directly to the
outdoors or spaces open to the outdoors. These spaces include
attics and crawl spaces. In most cases for direct communication
with the outdoors or direct communication through a vertical duct
a free area opening of one square inch per 4,000 BTU/HR of heater
input rating for each grill. If a horizontal duct is used, a grill free
area or duct opening shall have a free area opening of one square
inch per 2,000 BTU/HR for each grill. Follow the National Fuel
Code NFPA 54/ANSI Z223.1, Section 5.3 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.
Figure 5
WARNING: Rework worksheet, adding the space of the
adjoining unconfined space. The combined spaces must have
enough fresh air to supply all appliances in both spaces.

Note: Never use plastic pipe. Check to confirm whether your local
codes allow copper tubing or galvanized.
Note: Since some municipalities have additional local codes, it is
always best to consult your local authority and installation code.
Installing a New Main Gas Cock
Each appliance should have its own manual gas cock.
A manual main gas cock should be located in the vicinity of
the unit. Where none exists, or where its size or location is not
adequate, contact your local authorized installer for installation
or relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liquefied petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed flame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required
by the National Fuel Gas Code that a drip line be installed near
the gas inlet. This should consist of a vertical length of pipe tee
connected into the gas line that is capped on the bottom in which
condensation and foreign particles may collect.
The use of the following gas connectors is recommended:
— ANS Z21.24 Appliance Connectors of Corrugated Metal Tub-
ing and Fittings
— ANS Z21.45 Assembled Flexible Appliance Connectors of
Other Than All-Metal Construction
The above connectors may be used if acceptable by the authority
having jurisdiction. The state of Massachusetts requires that a flex-
ible appliance connector cannot exceed three feet in length.
Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8" (3mm) N.P.T.
plugged tapping, accessible for test gauge connection, must
be placed immediately upstream of the gas supply connection
to the appliance.
2. Th e ap plianc e and its ind ividual shu toff v alve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of
1/2 psig (3.5 kPa).
3. The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig (3.5 kPa).
Figure 7
Attention! If one of the above procedures results in pressures in
excess of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas valve,
it will result in a hazardous condition.
Checking Manifold Pressure
(A)VFD26F(M,P)3 Natural gas will have a manifold pressure of
approximately 3.5" w.c. (.871kPa) for maximum input or 1.7" w.c.
(.423kPa) for minimum input at the pressure regulator outlet with
the inlet pressure to the pressure regulator from a minimum of 5.0"
w.c. (1.120kPa) for the purpose of input adjustment to a maximum
of 10.5" w.c. (2.614kPa).
(A)VFD26F(M,P)2 Natural gas will have a manifold pressure of
approximately 6.0" w.c. (1.49kPa) at the pressure regulator outlet

PLACEMENT OF GLOWING EMBERS (ROCK WOOL)
Provided with the log set is a small bag of glowing embers (rock
wool) to be placed between logs on the flat metal surface of the
burner.
Placement of the embers (rock wool) is very individual and light
coverage of the areas indicated will provide your best effects. We
recommend separation of the rock wool by hand and make your
coverage as light and fluffy as possible.
Place just enough embers (rock wool) on the burner to obtain the
glow and a gold yellow flame.
Do not place rock wool over large ports in rear portion of burner.

OPERATION INSTRUCTIONS/FLAME APPEARANCE
Flames from the pilot (rear right back side of the burner) as well
as the main flame should b e visually checked as the log set is
installed.
In normal operation at full rate after 10 to 15 minutes, the flame
appearance should be sets of yellow flames.
NOTE: All flames will be random by design, flame height will
go up and down.
Glowing embers (rock wool) can cover the burner in between the
front and middle logs, but very little is necessary to cover this
area. Excess ember material causes the yellow flame to become
orange and stringy. Apply just enough to obtain slow glow and a
gold, yellow flame.
Avoid any drafts that alter burner flame patterns. Do not allow fans
to blow directly into fireplace. Do not place a blower inside the
burner area of the firebox. Ceiling fans may create drafts that alter
flame patterns. Sooting and improper burning will result.

components of this appliance are treated with certain oils, films or
bonding agents. These chemicals are not harmful, but may produce
annoying smoke and smells as they are burned off during the initial
operation of the appliance, possibly causing headaches or eye or
lung irritation. This is a normal and temporary occurrence.
The initial break-in operation should last 2-3 hours with the burner
at the highest setting. Provide maximum ventilation by opening
windows or doors to allow odors to dissipate. Any odors remaining
after this initial break-in will be slight and will disappear w ith
continued use.

PILOT FLAME CHARACTERISTICS
Figures 15 and 18 show a correct pilot flame pattern. The correct
flame will be blue and will extend beyond the thermocouple. The
flame will surround the thermocouple just below the tip. A slight
yellow flame may occur where the pilot flame and main burner flame
meet. Figures 16 and 19 show an incorrect pilot flame pattern. The
incorrect pilot flame is not touching the thermocouple. This will
cause the thermocouple to cool. When the thermocouple cools, the
heater will shut down.
