GENERAL INFORMATION

The VFST and VFPF Series Unvented Room Heaters covered in this manual feature a unitized set of eight (8) ceramic fiber split logs.

These heaters have a standing pilot and may be manually controlled through the use of an on/ off wall switch or wall thermostat or any combination of both of them.

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 VFST and VFPF Series Unvented Room Heaters must be built into a framed wall.

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.

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 the Unvented Gas Heater serviced 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 VFST and VFPF 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.

Any safety screen or guard removed for servicing the heater must be replaced prior to operating the heater.

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.

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.

Test gage connections are provided on the front of the gas control valve (identified A for the manifold side and E for inlet pressure).

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. (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 T- handle type valve.

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.

NOTE: DIAGRAMS & ILLUSTRATION NOT TO SCALE.

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.

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: 16' (L) x 16' (W) x 8' (H) = 2048 ft 3

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: 3072 ft 3 / 50 ft 3 = 40.96

or 40,960 BTU/Hr the space can support.

3.Add the BTU/Hr of all the fuel burning appliances in the space.

(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.

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.

4

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.

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 VFST or VFPF 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 VFST or VFPF 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.

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.

To ensure even heat distribution, it is best to position the heater centrally within the rooms. Make sure there is adequate ventilation where the heater is installed. The gas appliance will shut off if the oxygen level falls below 18%.

NOTE: DIAGRAMS & ILLUSTRATION NOT TO SCALE.

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 appliance to the underside of combustible materials used to construct a utility shelf is 43-1/4” (1099 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.

Step 3. Remove the nailing flanges from the lower control compartment and install in place with three (3) screws each. Align with the three holes on each side of the appliance (refer to

Figure 5 ).

Install the hood on all units. Position the hood in the open area above the appliance door. Insert the tabs, on each end of the hood, into the bracket at each end. Bend the two tabs over to secure.

Step 4. Position appliance into prepared framing, secure with 6d nails at the nailing flange along each side.

Step 5. Connecting Gas Line – Make gas line connections. All codes require a shut-off valve mounted in the supply line. Figure 10 illustrates two methods for connecting the gas supply. Installation methods and materials must be in compliance with local codes.

The gas control valve is located in the lower control compartment. To access the valve open the lower control compartment door (Figure 11 ). The control valve has a 3/8" NPT thread inlet port and is fitted with a 3" (76 mm) long nipple, 3/8" NPT on both ends. Plan the connections accordingly.

Route the gas line using techniques and materials prescribed by local and/or national codes. If the gas line must be routed from the left hand side (viewed from the gas controls), route the gas line around the valve and connect to the valve from the right hand side. The left hand gas line opening has been offset to allow for easy attachment of hard piping from the left hand side, when hard piping (black iron) is required by local codes.

For ease in installation, the offset is designed to utilize (1) a 3/8" street elbow at the valve, replacing the nipple provided with the appliance and oriented to the rear, (2) a 6", 3/8" nipple and (3) a 3/8" standard elbow returning to the left and aligning with a gas line routed through the left hand opening.

Secure all joints tightly using appropriate tools and sealing compounds (ensure propane resistant compounds are used in propane applications).

Turn on gas supply and test for gas leaks, using a gas leak test solution (also referred to as bubble leak solution).

Note: Using a soapy water solution (50% dish soap, 50% water) is an effective leak test solution but it is not recommended, because the soap residue that is left on the pipes/ fittings can result in corrosion over time. Never use an open flame to check for leaks.

A.Light the appliance (refer to safety and lighting instructions on page 15) (See *Note).

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.
