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.

•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 professionalserviceperson.Morefrequentcleaning 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.

•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.

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.

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 T- handle type valve.

NOTE: DIAGRAMS & ILLUSTRATION NOT TO SCALE.

•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 ft 3 per 1,000 BTU input of all operating appliances in the space.

The National Fuel Gas Code defines a confined space as a space whose volume is less than 50 ft 3 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 ft 3 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 3.

Length x Width x Height = _____ ft 3 (Include adjoining rooms with doorless passageways or ventilation grills between rooms.)

Example: 20' (L) x 16' (W) x 8' (H) = 2560 ft 3

2.Divide the volume of space by 50 ft 3 to determine the maximum BTU/Hr the space can support.

______ (volume of space – ft 3)/ 50 ft 3 = (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.

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.

4

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.

Your options are:

a.Rework equations adding the space of adjoining 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.

NOTE: DIAGRAMS & ILLUSTRATION NOT TO SCALE.

•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.

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.

Do not install in the vicinity of gasoline or other flammable liquids. The heater must be kept clear and free from these combustible materials and may not be located near where they are stored.

Clearances

WARNING: DO NOT INSTALL VF SERIES UNVENTED ROOM HEATERS IN SLEEPING QUARTERS, OR IN RECREATIONAL VEHICLES.

PREINSTALLATION

Check that all listed parts have been received.

Carefully inspect the heater case and contents for shipping damage and immediately inform the dealer from whom you purchased the gas fireplace if any damage is found.

The appliance is shipped with all gas controls and components installed and pre-wired. Remove the shipping carton. The nailing flanges are installed at each side of the appliance backwards when shipped from the factory to protect the unit from shipping damage. Remove the nailing flanges and retain for use when installing the appliance in framing. Remove three screws and remove the screen panel. Remove the logs and set aside.

Check Gas Type

This appliance can only be connected to the gas type specified on the appliance data plate. This appliance can not be modified in the field for a different gas type. If the gas type to be used is not the one specified contact the dealer to obtain the correct gas appliance.

Note: Illustrations shown in this manual reflect “typical” installations with nominal dimensions and are for design and framing reference only. Actual installations may vary due to individual design preferences. However, always maintain minimum clearances to combustible materials and do not violate any specific installation requirements.

NOTE: DIAGRAMS & ILLUSTRATION NOT TO SCALE.

Note: The following steps represent the normal sequence of installation. Each installation is unique, however, and might require a different sequence.

CAUTION: HEATERS CREATE WARM AIR CURRENTS. THESE CURRENTS MOVE HEAT TO WALL SURFACES NEXT TO HEATER. INSTALLING HEATER NEXT TO VINYL OR CLOTH WALL COVERINGS OR OPERATING HEATER WHERE IMPURITIES IN THE AIR (SUCH AS TOBACCO SMOKE) EXISTS, MAY DISCOLOR WALLS.

Step 1. Position heater in desired location (freestanding, onto surround base or into prepared framing) and secure.

Step 2. Plumb gas line. (Gas connections should only be performed by an experienced, licensed/ certified tradesman.)

Step 3. Assemble logs and test flame appearance.

Step 4. Complete finish wall material, surround and optional hearth extension to your individual taste.

INSTALLATION STEPS

Built-In Systems

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.

Do not burn solid fuels in this listed unvented gas room heater.

Step 1. Frame VF4000 appliance enclosures as illustrated in Figures 4, 5 and 6.

Note: The framed depth (15-1/2" for a flat wall, 29" for a corner VF4000) must always be measured from a finished surface. If a wall covering such as drywall is to be attached to the rear wall, then the dimension must be measured from the drywall surface.

Note: Framing dimensions in Figures 4 - 6 are calculated for a nailing flange depth of 1/2" (13 mm).

A.Light the appliance (refer to safety and lighting instructions on pages 14 and 16).

B.Brush all joints and connections with the gas leak test solution to check for leaks. If bubbles are formed, or gas odor is detected, turn the gas control knob to the “OFF” position. Either tighten or refasten the leaking connection and retest as described above.

C.When the gas lines are tested and leak free, be sure to rinse off the leak testing solution.

D.When the gas lines are tested and leak free, observe the individual tongues of flame on the burner. Make sure all ports are open and producing flame evenly across the burner. If any ports are blocked, or partially blocked, clean out the ports.

An external regulator must be used on all propane (L.P.G.) heaters, in addition to the regulator fitted to the heater, to reduce the supply tank pressure to 13" w.c. (maximum).

WARNING: CONNECTING DIRECTLY TO AN UNREGULATED PROPANE TANK CAN CAUSE AN EXPLOSION.

Step 5. Installing the Optional Remote Wall Switch (VF4000-CMN/P models only) – The millivolt system comes from the factory wired as shown in Figure 10. Select a convenient location for the remote wall switch and connect the wiring to the appliance (Figure 11 ).

CAUTION: DO NOT CONNECT THE OPTIONAL REMOTE SWITCH TO A 120V POWER SUPPLY.

Note: The optional rocker switch is mounted to the appliance and wired in the same way as the remote wall switch.

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 ).

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 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.

8

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.

Step 8. Secure Heater – Bend the tabs down (Figure 13 ). Using two (2) screws securely tighten the appliance to the platform.

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.

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 components and secure the surround to the appliance.

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 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.

Figure 14

After setting the logs into position as described above, ensure they are properly and firmly situated. The heater will not function as intended if the logs are not correctly positioned.

Periodically check the positioning of the logs.

WARNING: FAILURE TO POSITION THE PARTS IN ACCORDANCE WITH THESE DIAGRAMS OR FAILURE TO USE ONLY PARTS SPECIFICALLY APPROVED WITH THIS HEATER MAY RESULT IN PROPERTY DAMAGE OR PERSONAL INJURY.

Flame Appearance

REFER TO THE OPERATING INSTRUCTIONS LOCATED AT THE BACK OF THIS MANUAL BEFORE LIGHTING THE HEATER TO OBSERVE THE FLAMES.

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 ).

WARNING: NO ADJUSTMENTS ARE TO BE MADE TO THE ODS PILOT SYSTEM. TAMPERING WITH THIS SYSTEM CAN BE EXTREMELY HAZARDOUS.
