CONTROLS IS DANGEROUS. IMPROPER  
INSTALLATION OR USE OF THIS HEATER  
CAN CAUSE SERIOUS INJURY OR DEATH  
FORM FIRE, BURNS, EXPLOSION OR  
CARBON MONOXIDE POISONING.  
• A working smoke detector must be installed  
in the area where vent-free appliances are  
installed.  
Any safety screen or guard removed for  
servicing the heater must be replaced prior to  
operating the heater.  
Seller of unvented propane or natural gas-  
fired supplemental room heaters shall pro-  
vide to each purchaser a copy of 527 CMR 30  
upon sale of the unit.  
Keep heater area clear and free from com-  
bustible materials, gasoline and other flam-  
mable vapors and liquids.  
New York:  
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  
Adhere to all local codes or in their absence the

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.

Use the following equations to determine if you  
have a confined or unconfined space.  
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.  
3
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.  
WARNING: MAINTAIN MINIMUM  
CLEARANCES.

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.

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.

PARTS IN ACCORDANCE WITH THESE  
DIAGRAMS OR FAILURE TO USE ONLY  
PARTS SPECIFICALLY APPROVED WITH  
THIS HEATER MAY RESULT IN PROP-  
ERTY DAMAGE OR PERSONAL INJURY.  
When first lighting the appliance, it will take a  
few minutes for the line to purge itself of air.  
Once purging is complete, the pilot and burner  
will light and operate as indicated in the instruc-  
tion manual. Subsequent lightings of the appli-  
ance will not require such purging. Inspect the  
pilot flame (remove logs, if necessary, handling  
carefully).

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
