These fireplaces are approved for installation
in the US state of New York, but not in New
York City.
• Do not use these appliances if any part has
been under water. Immediately call a qualified
professional service technician to inspect the
appliance and to replace any parts of the control
system and any gas control which have been
under water.
Carbon Monoxide Poisoning: Early signs of
carbon monoxide poisoning are similar to the
flu with headaches, dizziness and/or nausea. If
you have these signs, obtain fresh air immedi-
ately. Turn off the gas supply to the heater and
have it serviced by a qualified professional, as
it may not be operating correctly.
COMBUSTION AND VENTILATION AIR
These heaters shall not be installed in a con-
fined space. The heater may be located in
unusually tight construction provided the
space is unconfined, or if confined, is pro-
vided with two permanent openings commu-
nicating directly with an additional room(s)
of sufficient volume so that the combined
volume of all connected spaces meets the
criteria for an unconfined space, (National
Fuel Gas Code ANSI Z223.1 (latest edition),
Section 5.3). Generally 50 ft3 per 1,000 BTU
input of all operatingappliances in the space.
• Input ratings are shown in BTU per hour and
are for elevations up to 7,000 feet. Operating
heater above elevations of 7,000 feet may cause
ODS pilot outage.
• Due to high temperatures, the heater should
be located out of traffic and away from furniture
and draperies.
• Ensure that the heater is clean when operat-
ing. Excessive dust accumulation on the burner
and logs will increase the amount of carbon
monoxide formation and could lead to carbon
monoxide poisoning and death.
• Children and adults should be alerted to the
hazard of high surface temperatures and should
stay away to avoid burns or clothing ignition.
CODES
• Young children should be carefully super-
vised when they are in the same room with
the heater.
The National Fuel Gas Code defines a con-
fined space as a space whose volume is less

than 50 ft 3 per 1,000 BTU/Hr (4.8 m per kw)
of the aggregate input rating of all appliances
installed in that space and an unconfined
space as a space whose volume is not less
than 50 ft3 per 1,000 BTU/Hr (4.8m3 per kw)
of the aggregate input rating of all appliances
installed in that space. Rooms communicat-
ing directly with the space in which the appli-
ances are installed, through openings not
furnished with doors, are considered a part of
the unconfined space.
• Do not place clothing or other flammable
material on or near the heater for the purpose
of drying.
• Installation and repair should be done by a
qualified service person. The heater should be
inspected before use and at least annually by a
professional service person. More frequent clean-
ing may be required due to excessive lint from
carpeting, bedding material, etc. It is important
that control compartments, burners and circulat-
ing air passageways of the heater be kept clean.

• This appliance may be installed in an after-
market* manufactured (Mobile) Home, where
not prohibited by state or local codes.
*Aftermarket: Completion of sale, not for pur-
pose of resale, from the manufacturer.
WARNING: IF THE AREA IN WHICH THE
HEATER MAY BE OPERATED IS SMALLER
THAN THAT DEFINED AS AN UNCON-
FINED SPACE, PROVIDE ADEQUATE
COMBUSTION AND VENTILATION AIR BY
ONE OF THE METHODS DESCRIBED IN
THE NATIONAL FUEL GAS CODE, ANSI
Z223.1 1992, SECTION 5.3 OR APPLI-
CABLE LOCAL CODES.
1. Determine the volume of space — ft 3.
Length x Width x Height = _____ ft 3
(Include adjoining rooms with doorless pas-
sageways or ventilation grills between
rooms.)
• Minimize modifications to existing construc-
tion. Refer toFigure 1 for location suggestions.

Example: 20' (L) x 16' (W) x 8' (H) = 2560 ft
2. Divide the volume of space by 50 ft
3 to
Your options are:
determine the maximum BTU/Hr the space
can support.
a. Rework equations adding the space of ad-
joining room(s). If the extra volume provides
an unconfined space, then remove door or
add ventilation grills between rooms. Refer
to National Fuel Gas Code, ANSI Z223.1
1992, Section 5.3.

______ (volume of space – ft 3)/ 50 ft
=
(Maximum BTU/Hr the space can support)
Example: 2560 ft 3 / 50 ft 3 = 51.2
or 51,200 BTU/Hr the space can support.
b. Vent room directly to the outdoors. Refer to
National Fuel Gas Code, ANSI Z223.1 1992,
Section 5.3.
Figure 1
3. Add the BTU/Hr of all the fuel burning appli-
ances in the space.
To ensure even heat distribution, it is best to
position the heater centrally against the longest
wall of the room. Make sure there is adequate
ventilation where the heater is installed. The
gas appliance will shut off if the oxygen level
falls below 18%.
c. Install a lower BTU/Hr heater, to make the
area an unconfined space.
Vent-Free heater
Gas appliance #1*
Gas appliance #2
_______ BTU/Hr
_______ BTU/Hr
+ _______ BTU/Hr
If the actual BTU/Hr used is less than the
maximum BTU/Hr the space can support, then
the space is an unconfined space. You will need
no additional fresh air ventilation for an uncon-
fined space.
Total = _______ BTU/Hr
These appliances are uniquely suited for instal-
lations requiring a utility shelf positioned di-
rectly above the fireplace. Utility shelves like
these are commonly used for locating televi-
sion sets and decorative plants.
Example:
VF4000 Vent-free heater 25,000 BTU/Hr
Gas appliance #1
(water heater)
34,000 BTU/Hr
LOCATION OF FIREPLACE
Total = 59,000 BTU/Hr
Carefully select the best location for installa-
tion of your VF4000 series Unvented Room
Heater. The following factors should be taken
into consideration:
To provide for the lowest possible shelf sur-
face, combustible materials used to support a
utility shelf directly above these appliances
should be positioned just above the appliance
top spacers. The minimum height from the
base of the VF4000 to the underside of com-
bustible materials used to construct a utility
shelf is 37-1/4” (946 mm).
* Do not include direct-vent gas appliances.
Direct-vent is sealed combustion and draws
combustion air from the outdoors.
4. Compare the maximum BTU/Hr the space
can support with the actual amount of BTU/
Hr used.
• Clearance to side wall, ceiling, woodwork
and windows.
• Location must not be affected by drafts
caused by kitchen exhaust fans, return air reg-
isters for forced air furnaces/air conditioners,
windows or doors.
_________ BTU/Hr
(max. the space can support)
_________ BTU/Hr
The appliance should be mounted on a fully
supported base extending the full width and
depth of the unit. The appliance may be located
on or near conventional construction materi-
als. However, if installed on combustible mate-
rials, such as carpeting, vinyl tile, etc., a metal
or wood barrier covering the entire bottom
surface must be used.
(actual amount of BTU/Hr used)
• Installation must provide adequate ventila-
tion and combustion air.
Example:
51,200 BTU/Hr
(max. the space can support)
59,000 BTU/Hr
• Do not install the VF4000 series heaters in a
sleeping room or bathroom.
(actual amount of BTU/Hr used)
If the appliance is to be elevated above floor
level, a solid continuous platform must be
constructed.
• Never obstruct the front opening of the heater
or restrict the flow of combustion and ventila-
tion air.
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 sup-
port. You must provide additional fresh air.

cover plate. Failure to do so will prevent the
appliance from operating.
Assembling the Logs
WARNING: DO NOT ADD EXTRA LOGS OR
ORNAMENTS SUCH AS PINE CONES, VER-
MICULITE OR ROCK WOOL. USING THESE
ADDED ITEMS CAN CAUSE SOOTING.
The appliance must be electrically grounded in
accordance with local codes or, in the absence
of local codes, the National Electrical Code,
ANSI/NFPA 70-(latest edition). (In Canada, the
current CSA C22-1 Canadian Electrical Code.)
WARNING: DO NOT PLACE ANY LAVA
ROCK ON LOGS OR BURNERS. THIS MAY
CAUSE SOOTING.
The forced air blower kit may be mounted at
initial appliance installation or at any time there-
after. Follow the instructions provided with the
blower kit.
Step 12. The heater includes a unitized set of
ceramic fiber logs. The heater and logs are
assembled as shown in Figure 14 . Handle
these logs with great care. The logs can be
easily damaged, but when handled properly
they can provide years of performance and
enjoyment.
Finished Wall Details
It is sometimes best to frame the appliance
after it has been positioned in place. Frame with
2 x 4s or heavier lumber. Always frame in
accordance with local building codes.
Figure 13
Note: The heater may be installed directly on a
floor made of standard combustible wood con-
struction materials. Do not install the heater
directly on carpeting or other soft floor cover-
ing such as vinyl tile or flooring materials. Use
a wood or metal panel that extends the full
width and depth of the heater between the
heater and any soft floor covering material.
Refer to Figure 20 for base dimensions.
Note: The header may rest on the top spacers
but must not be notched to fit around them.
In order to install the appliance facing flush with
the finished wall, position the framework to
accommodate the thickness of the finished wall
(Refer to Figures 2 and 3 ).
Step 8. Secure Heater – Bend the tabs down
(Figure 13 ). Using two (2) screws securely
tighten the appliance to the platform.
If you live in a cold climate, seal all cracks
around your appliance with noncombustible
material and wherever cold air could enter the
room. It is especially important to insulate
outside chase cavity between studs and under
floor on which appliance rests, if floor is above
ground level.
Note: Heater must be anchored to the floor or
platform.
Step 9. Install Optional 120V Wiring –Refer
to Step 6 for wiring instructions.
Proceed to Step 10.
Connecting Gas Line
Surround Installations
Step 10. A qualified gas appliance installer
must connect the gas room heater to the gas
supply.
Note: The VF4000 series appliances must be
installed giving full consideration to the clear-
ance and height requirements identified in this
manual.
Consult all local codes and refer to Step 5.
Step 7. Position Heater – Place the heater in
desired location. It may be helpful to tempo-
rarily assemble the surround around the appli-
ance to properly locate the unit. Refer to
Figure 13 for floor and platform installations.
If the heater is to be installed into a framed wall
refer to the built-in assembly steps beginning
on page 5.
The heater gas inlet connection is 3/8" NPT,
located on the right side facing the heater. If a
left side connection is required, route the gas
line under the valve to end at the right hand side
for connection to the inlet. This may be re-
quired to allow for installation of the blower.
When tightening up the joint to the valve hold
the valve securely with a wrench to prevent the
valve from moving.
Step 11 . For Surround Installations Only –
Finish the assembly of the surround compo-
nents and secure the surround to the appliance.

After setting the logs into position as described
above, ensure they are properly and firmly
situated. The heater will not function as in-
tended if the logs are not correctly positioned.
Step 13. Checking the System –With gas line
installed run initial system checkout before
closing up the front of the unit. Follow the pilot
lighting instructions on pages 14 and 16.

utes the following flame appearance should be
observed:
Flame Appearance
REFER TO THE OPERATING INSTRUCTIONS
LOCATED AT THE BACK OF THIS MANUAL
BEFORE LIGHTING THE HEATER TO OBSERVE
THE FLAMES.
The pilot flame should be steady, not lifting or
floating. Flame should be blue in color with
traces of orange at the outer edge.
Rear Burner Flame Characteristics –The rear
flames should be yellow. The flames should
extend about 3 – 4" above the front log for
natural gas and 2 – 3" above for propane
(L.P.G.) gas (Figure 17 ).
The top 3/8" (10 mm) at the pilot thermocouple
should be engulfed in the pilot flame (NG only).
Flames from the pilot, front and rear burner
should be visually checked as soon as the
heater is installed. In addition a periodic visual
check of the flames should be made. The pilot
flame should always be present when the heater
is in operation and should just envelope the tip
of the thermocouple (Figure 15 ).
Replace logs if removed for pilot inspection.
To light the burner; rotate the gas valve control
knob counterclockwise to the “ON” position.
Step 14. Installing the Hood Assembly –
Attach the hood assembly over the firebox
opening with three (3) screws.

a two stage (HI, LOW) gas control valve. To set normal use of the heater. Dust the front grate, the
the burner at the HI and LOW settings, rotate
the control knob to the desired position.
Only limited cleaning will be required under the
top of the piezo cover and the control knob
occasionally. Do not use cleaning fluids to clean
the logs or any other part of the room heater.
Wall Switch Kit
3. When lit for the first time, the appliance will
emit a slight odor for an hour or two. This is
due to the “burn-in” of the internal paints and
lubricants used in the manufacturing process.
Additionally, when lit for the first time, this
appliance may produce smoke, this is normal
and should be expected. For the first few
hours, operate the appliance with doors and
windows open to encourage the dissipation of
smoke and fumes.
Remove the log assembly, gently handling by
holding each log at each end. Use a vacuum
cleaner to remove loose particles from the base
and from around the burners. Gloves are rec-
ommended to prevent the fibers from pricking
your skin. If the skin is pricked, wash gently
with soap and water. Replace the logs as de-
tailed in Step 12 Assembling the Logs.
An optional wall switch kit can be installed
along with the millivolt controlled appliances.
The kit consists of a standard UL wall switch
with cover plate. This kit provides for remote
(wall) operation of the appliance. Replace the
wall switch and cover plate of this kit with the
components of the FWSK and you can have true
remote control of your vent-free appliance,
turning it on and off from your favorite easy
chair. The wall switch kit should be installed
along with the appliance. Refer to Figure 11
and Step 5 for detailed installation instructions.
If, after a period of use, the flames start to
exhibit unusual shapes and behavior, or the
burners fail to ignite smoothly, then the burner
holes may require some cleaning. If this hap-
pens, it is preferable to contact your nearest
dealer to get the appliance serviced.
4. Keep lower control compartment clean by
vacuuming or brushing at least twice a year.
More frequent cleanings may be required due
to excessive lint from carpeting, bedding ma-
terials, etc. It is important that the control
compartments, burners and circulating air pas-
sageways of the heater be kept clean.
