IMPORTANT SAFETY INFORMATION
DANGER: Indicates a hazardous situation which, if not avoided, will
result in death or serious injury.
WARNING: Indicates a hazardous situation which, if not avoided,
could result in death or serious injury.
CAUTION: Indicates a hazardous situation which, if not avoided,
could result in minor or moderate injury.
NOTICE: Addresses practices not related to personal injury.
• 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
trafc 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 ammable material on or near the
appliance.
• Avoid the use of scented air fresheners (plug in type air
fresheners, etc. ) while the log set is in operation. Air fresheners
produce a residue in the air similar to candles and may produce
a soot like substance.
• Avoid the use of scented or decorative candles while the log
set is in operation. Candles produce a residue in the air that
creates a soot like substance. Burning candles while the log
set is operating magnies the problem. It should be noted that
candles, in general, produce soot. The amount of time burned
and the quantity of candles burned will determine the amount
of soot produced and deposited.
• 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 room heater if any part has been under water.
Immediately call a qualied service technician to inspect the
room heater and to replace any part of the control system and
any gas control which has been under water.
• You must operate heater with replace screen in place.
• 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, lms
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 ber logs, proper location of
the heater and annual cleaning are necessary to avoid potential
problems with sooting. Sooting, resulting from improper
installation or operation, can settle on surfaces outside the
replace. See instructions for proper installation.

• Keep appliance area clear and free from combustible materials,
•
WARNING! This replace needs fresh air for ventilation to
run properly. This replace has an ODS (oxygen depletion
sensor) which will shut down the heater if adequate fresh air is
not available. See troubleshooting section in the instructions.
WARNING: DO NOT operate this appliance unless all
components including logs, burners, and controls are in good
working condition. Never operate this appliance if any log or
twig is broken, or out of their intended position. Refer to the
Log set placement instructions for correct log and twig
positioning.

gasoline and other ammable vapors and liquids.
WARNING: Failure to keep the primary air opening(s) of the
burner(s) clean may result in sooting and property damage.
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/NFPA 54, Air for Combustion and Ventilation, 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 u,
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 inuence 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 ow is not directed at
the burner.

SAFETY INFORMATION FOR USERS OF PROPANE GAS
Propane is a ammable gas which can cause res and explosions. In its natural state, propane is odorless and colorless.
You may not know all the following safety precautions which
can protect both you and your family from an accident. Read
them carefully now, then review them point 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 reading the following information,
you feel you still need more information, please contact your
gas supplier.
PROPANE GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the Propane 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.
• Propane 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 reghters declare them to be safe.
• Use your neighbor's phone and call a trained Propane Gas
service person and the re 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 reghters check for escaped
gas. Have them air out the area before you return. Properly
trained Propane Gas service people should repair the leak,
then check and relight the gas appliance for you.
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 nd 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 Propane 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 lter the odorant.
Odorants in Propane Gas also are subject to oxidation. This fading
can occur if 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.
Propane 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 Propane Gas. Your local
Propane Gas Dealer can give you a "Scratch and Sniff" pam-
phlet. Use it to nd out what the propane odor smells like. If
you suspect that your Propane Gas has a weak or abnormal
odor, call your Propane Gas Dealer.
• If you are not qualied, do not light pilot lights, perform service, or make adjustments to appliances on the Propane
Gas system. If you are qualied, consciously think about the
odor of Propane 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 Propane 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 Propane 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 lled and allowed to set too
long before relling. Cylinders and tanks which have been
out of service for a time may develop internal rust which will
39025-2-0620 Page 5
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 Propane Gas Dealer.
A periodic sniff test of the Propane Gas is a good safety
measure under any condition.
• If, at any time, you do not smell the Propane 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 Propane Gas.
• If you experience a complete "gas out," (the container is under 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 orices. 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
relled before it is completely empty.

750 Millivolt System
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 ame 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 energy) to build-up to a sufcient 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.
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 dehumidier 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 conned space or unusually
tight construction unless provisions are provided for adequate
combustion and ventilation air.
A conned space is an area with volume less than 50 cubic feet per
1,000 Btuh of the combined input rates of all appliances drawing
combustion air from that space. Small areas such as equipment
rooms are conned spaces. Furnaces installed in a conned space
which supply heated air to areas outside the space must draw return
air from outside the space through tightly sealed return air ducts. A
conned space must have 2 openings into the space for combustion
air. One opening must be within 12 inches of the ceiling and the
other must be within 12 inches of the oor. The required sizing of
these openings is determined by whether inside or outside air is
used to support combustion, the method by which the air is brought
to the space (vertical or horizontal duct) and by the total input rate
of all appliances in the 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 dened 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. 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 9.
Determining if You Have a Conned or Unconned Space
Use this worksheet to determine if you have a conned or unconned
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 =
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.
BTU/Hr the space can support)
Example: 1,280 cu. ft. (volume of space) ÷ 50 cu. ft. = 25.6 or
3. Add the BTU/Hr of all fuel burning appliances in the space.

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.

PROVISIONS FOR ADEQUATE COMBUSTION & VENTILATION AIR
The space in the above 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.
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
unconned.
If the actual BTU/Hr used is less than the maximum BTU/Hr the
space can support, the space is an unconned space. You will need
no additional fresh air ventilation.
WARNING
You must provide additional ventilation air in a conned space.
VENTILATION AIR
Ventilation Air From Inside Building (Figure 1)
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 wall connecting the two spaces (see options
1 and 2, Figure 1). You can also remove door into adjoining room
(see option 3, Figure 1). Each ventilation grill or opening shall have
a minimum free area of one square inch per 1,000 BTUH of the total
input rating of the gas equipment in the conned space.
Ventilation Air From Outdoors (Figure 2)
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 oor. 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 ANSI
Z223.1/NFPA54, 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.

NOTE: Never use plastic pipe. Check to conrm 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 Shut-Off
Each appliance should have its own manual gas shut-off.
A manual main gas shut-off 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 liqueed 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 ame 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.

Checking Manifold Pressure
VFPA(32,36)BP(30,31)LN (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 4.5" w.c. (1.120kPa) for the purpose of input adjustment to a
maximum of 10.5" w.c. (2.614kPa).
VFPA(32,36)BP(70,71)LN (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 4.5" w.c. (1.120kPa) for the purpose of input adjustment to a
maximum of 10.5" w.c. (2.614kPa).
VFPA(32,36)BP(30,31) (Propane Gas) will have a manifold pressure
approximately 10.0"w.c. (2.49kPa) for maximum input or 4.9"w.c.
(1.220kPa) for minimum input at the pressure regulator outlet with the
inlet pressure to the pressure regulator from a minimum of 11.0"w.c.
(2.739kPa) for the purpose of input adjustment to a maximum of
13.0"w.c. (3.237kPa).
CLEARANCES
Minimum Wall and Ceiling Clearances
Sidewall Clearances: The clearance from the inside of the replace
to any combustible wall should not be less than 2".
Fireplace Side and Back Clearances: The replace outer casing
sides and back have zero clearance to combustibles.
Ceiling Clearances: The ceiling height should not be less than 36"
from the top of the hood.
Mantel Clearances: Vent free replace models must use the hood
supplied with the replace. If a combustible mantel is installed, it
must meet the clearance requirements detailed above.
VFPA(32,36)BP(70,71) (Propane Gas) will have a manifold pressure
approximately 10.0"w.c. (2.49kPa) for maximum input or 4.9"w.c.
(1.220kPa) for minimum input at the pressure regulator outlet with the
inlet pressure to the pressure regulator from a minimum of 11.0"w.c.
(2.739kPa) for the purpose of input adjustment to a maximum of
13.0"w.c. (3.237kPa).
VFPA(32,36)BP(3,7)(0,1) Control
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 rmly
to re-seal. Do not over torque. Check for gas leaks.
