GENERAL INFORMATION
The VF4000 Series Unvented Room Heaters covered in this manual feature ceramic fiber split logs which glow realistically when the heater is operating.
These heaters are manually controlled. Models VF4000-CMN-2 and VF4000-CMP-2 feature a gas valve incorporating a millivolt operating system.
A spark ignition system (piezo) allows the heater pilot gas to be lit without the use of matches or batteries and permits operation of the heater during a power outage.
These heaters are fitted with a specially de­signed pilot (ODS) which responds to the amount of oxygen available in the room and shuts the heater off before the oxygen level drops below 18%. The pilot can be relit only when fresh air is available. Refer to the Com­bustion and Ventilation Air section.
The VF4000 Series Unvented Room Heaters may be built into a framed wall, or installed in an optional oak surround.
This heater has been tested to the standards of ANSI Z21.11.2 unvented heaters.
Do not install these unvented room heaters in a bedroom or bathroom as all units exceed maximum allowable BTU/Hr input of 10,000.

WARNING: FAILURE TO COMPLY WITH THE INSTALLATION AND OPERATING INSTRUCTIONS PROVIDED IN THIS DOCUMENT WILL RESULT IN AN IM­PROPERLY INSTALLED AND OPERAT­ING UNVENTED ROOM HEATER, VOID­ING ITS WARRANTY. ANY CHANGE TO THIS HEATER AND/OR ITS OPERATING CONTROLS IS DANGEROUS. IMPROPER INSTALLATION OR USE OF THIS HEATER CAN CAUSE SERIOUS INJURY OR DEATH FORM FIRE, BURNS, EXPLOSION OR CARBON MONOXIDE POISONING.
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 immedi­ately. Turn off the gas supply to the heater and have it serviced by a qualified professional, as it may not be operating correctly.
Due to high temperatures, the heater should
be located out of traffic and away from furniture and draperies.
Children and adults should be alerted to the hazard of high surface temperatures and should stay away to avoid burns or clothing ignition.
The heater must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure test­ing of the gas supply piping system at test pressures equal to or less than 1/2 psig.
Any safety screen or guard removed for servicing the heater must be replaced prior to operating the heater.
Keep heater area clear and free from com­bustible materials, gasoline and other flam­mable vapors and liquids.
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.
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.
Ensure that the heater is clean when operat­ing. 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.
• Vent-Free appliances may NOT be installed in bedrooms or bathrooms.
• A working smoke detector must be installed in the area where vent-free appliances are installed.
Seller of unvented propane or natural gas­fired supplemental room heaters shall pro­vide to each purchaser a copy of 527 CMR 30 upon sale of the unit.
New York:
These fireplaces are approved for installation in the US state of New York, but not in New York City.
COMBUSTION AND VENTILATION AIR
These heaters shall not be installed in a con­fined space. The heater may be located in unusually tight construction provided the space is unconfined, or if confined, is pro­vided with two permanent openings commu­nicating 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 operating appliances in the space.
Young children should be carefully super­vised when they are in the same room with the heater.
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 clean­ing may be required due to excessive lint from carpeting, bedding material, etc. It is important that control compartments, burners and circulat­ing air passageways of the heater be kept clean.
Allow the heater to cool before servicing. Always shut off any electricity or gas to the heater while performing service work.
Do not install the VF4000 series heaters in a bedroom or bathroom.
The installation must conform with local codes or, in the absence of local codes with the National Fuel Gas Code, ANSI Z223.1.
The heater and its individual shut-off valve must be disconnected from the gas supply piping system while performing any tests of the gas supply piping system at pressures in ex­cess of 1/2 psig.
CODES
Adhere to all local codes or in their absence the latest edition of The National Fuel Gas Code ANSI Z223.1 or NFPA54 which can be obtained from The American National Standards Insti­tute, Inc. (1430 Broadway, New York, NY,
10018) or National Fire Protection Association, Inc. (Batterymarch Park, Quincy, MA, 02269).
Massachusetts And New York Require­ments
These appliances are approved for installation in the following USA locations listed in the following:
Massachusetts:
These fireplaces are approved for installation in the US state of Massachusetts if the follow­ing additional requirements are met-
• Installation and repair must be done by a plumber or gas fitter licensed in the Common­wealth of Massachusetts.
• The flexible gas line connector used shall not exceed 36 inches (92 centimeters) in length.
• The individual manual shut-off must be a T­handle type valve.
NOTE: DIAGRAMS & ILLUSTRATION NOT TO SCALE.
The National Fuel Gas Code defines a con­fined space as a space whose volume is less than 50 ft3 per 1,000 BTU/Hr (4.8 m3 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 (4.8 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 is defined as con­struction where:
a. wall and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating or one perm or less with openings gasketed or sealed, and
b. weather stripping has been added on oper­able 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 wall­ceiling joints, between wall panels, at penetra­tions for plumbing, electrical, and gas lines, and at other openings.
3
Use the following equations to determine if you have a confined or unconfined space.
1.Determine the volume of space — ft Length x Width x Height = _____ ft
3
.
3
(Include adjoining rooms with doorless pas­sageways or ventilation grills between rooms.)
Example: 20' (L) x 16' (W) x 8' (H) = 2560 ft
WARNING: IF THE AREA IN WHICH THE HEATER MAY BE OPERATED IS SMALLER THAN THAT DEFINED AS AN UNCON­FINED 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 APPLI­CABLE LOCAL CODES.

This appliance may be installed in an after­market* manufactured (Mobile) Home, where not prohibited by state or local codes. *Aftermarket: Completion of sale, not for pur­pose of resale, from the manufacturer.
Minimize modifications to existing construc­tion. Refer to
Figure 1
for location suggestions.
2.Divide the volume of space by 50 ft3 to determine the maximum BTU/Hr the space can support.
______ (volume of space – ft3)/ 50 ft3 = (Maximum BTU/Hr the space can support)
3
Example: 2560 ft
/ 50 ft3 = 51.2
or 51,200 BTU/Hr the space can support.
3.Add the BTU/Hr of all the fuel burning appli­ances in the space.
Vent-Free heater _______ BTU/Hr Gas appliance #1* _______ BTU/Hr Gas appliance #2 + _______ BTU/Hr
Total = _______ BTU/Hr
Example:
VF4000 Vent-free heater 25,000 BTU/Hr Gas appliance #1 34,000 BTU/Hr (water heater)
Total = 59,000 BTU/Hr
* 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.
_________ BTU/Hr
(max. the space can support)
_________ BTU/Hr
(actual amount of BTU/Hr used)
Example:
51,200 BTU/Hr
(max. the space can support)
59,000 BTU/Hr
(actual amount of BTU/Hr used)
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: 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.
b.Vent room directly to the outdoors. Refer to
National Fuel Gas Code, ANSI Z223.1 1992, Section 5.3.
c. Install a lower BTU/Hr heater, to make the
area an unconfined space.
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 uncon­fined space.
LOCATION OF FIREPLACE
Carefully select the best location for installa­tion of your VF4000 series Unvented Room Heater. The following factors should be taken into consideration:
Clearance to side wall, ceiling, woodwork and windows.
Location must not be affected by drafts caused by kitchen exhaust fans, return air reg­isters for forced air furnaces/air conditioners, windows or doors.
Installation must provide adequate ventila­tion and combustion air.
Do not install the VF4000 series heaters in a sleeping room or bathroom.
Never obstruct the front opening of the heater or restrict the flow of combustion and ventila­tion air.
Figure 1
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%.
These appliances are uniquely suited for instal­lations requiring a utility shelf positioned di­rectly above the fireplace. Utility shelves like these are commonly used for locating televi­sion sets and decorative plants.
To provide for the lowest possible shelf sur­face, 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 com­bustible materials used to construct a utility shelf is 37-1/4” (946 mm).
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 materi­als. However, if installed on combustible mate­rials, such as carpeting, vinyl tile, etc., a metal or wood barrier covering the entire bottom surface must be used.
If the appliance is to be elevated above floor level, a solid continuous platform must be constructed.
WARNING: MAINTAIN MINIMUM CLEARANCES.

IMPORTANT: Ground lead must be connected to the green screw located on the junction box cover plate. Failure to do so will prevent the appliance from operating.
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.)
The forced air blower kit may be mounted at initial appliance installation or at any time there­after. Follow the instructions provided with the blower kit.
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.
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
).
Figure 13 Note: The heater may be installed directly on a
floor made of standard combustible wood con­struction materials. Do not install the heater directly on carpeting or other soft floor cover­ing 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.
Assembling the Logs
WARNING: DO NOT ADD EXTRA LOGS OR ORNAMENTS SUCH AS PINE CONES, VER­MICULITE OR ROCK WOOL. USING THESE ADDED ITEMS CAN CAUSE SOOTING.
WARNING: DO NOT PLACE ANY LAVA ROCK ON LOGS OR BURNERS. THIS MAY CAUSE SOOTING.
Step 12. The heater includes a unitized set of
ceramic fiber logs. The heater and logs are assembled as shown in these logs with great care. The logs can be easily damaged, but when handled properly they can provide years of performance and enjoyment.

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.
Proceed to Step 10.
Surround Installations
Note: The VF4000 series appliances must be
installed giving full consideration to the clear­ance and height requirements identified in this manual.
Step 7. Position Heater – Place the heater in desired location. It may be helpful to tempo­rarily assemble the surround around the appli­ance to properly locate the unit. Refer to
Figure 13
If the heater is to be installed into a framed wall refer to the built-in assembly steps beginning on page 5.
for floor and platform installations.
Step 8. Secure Heater – Bend the tabs down (
Figure 13
tighten the appliance to the platform.
). Using two (2) screws securely
Note: Heater must be anchored to the floor or platform.
Step 9. Install Optional 120V Wiring – Refer to Step 6 for wiring instructions.
Connecting Gas Line Step 10. A qualified gas appliance installer
must connect the gas room heater to the gas supply.
Consult all local codes and refer to Step 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 re­quired to allow for installation of the blower.
