Product Features

Operation

This firebox is designed for use with approved

ANSI Z21.11.2 decorative type unvented room heaters. (Physical size limitations apply. Refer to minimum firebox requirements supplied with log heater.) It requires no outside venting or chimney making installation easy and inexpensive. When used without the blower, the firebox requires no electricity making it ideal for emergency backup heat.

Blower Accessory

The circulating models will accept either a rotary type fan (model BK) or the triple radial fan blower system (model BK3) accessories. The blower circulates heated air from the firebox into the room. Use of blower is optional.

Refractory brick liner

Your firebox may feature a concrete refractory brick liner. As with all concrete liners, this liner may develop slight cracks when exposed to heat. These cracks will not affect the performance of the fireplace or vent-freegas logs.

Locating Firebox

Planning

Plan where you will install the firebox.This will save time and money later when you install the firebox. Before installation, consider the following:

1.Where the firebox will be located.Allow for wall and ceiling clearances (see Installation Clearances, page 9).

2.Everything needed to complete installation.

3.These models CANNOT be installed in a bedroom unless the maximum BTU rating of the installed vent-freelog set is less than 10,000 Btu/Hr.

Air For Combustion and Ventilation

WARNING: This heater shall not be installed in a room or space unless the required volume of indoor combustion air is provided by the method describedintheNational Fuel Gas Code, ANSI Z223.1/NFPA 54, theInternational Fuel Gas Code, or applicablelocalcodes.Readthe following instructions to insure proper fresh air for this and otherfuel-burningappliances in your home.

Today’s homes are built more energy efficient than ever. New materials, increased insulation and new construction methods help reduce heat loss in homes. Home owners weather strip and caulk around windows and doors to keep the cold air out and the warm air in. During heating months, home owners want their homes as airtight as possible.

While it is good to make your home energy efficient, your home needs to breathe. Fresh air must enter your home. All fuel-burningappliances need fresh air for proper combustion and ventilation.

Exhaust fans, fireboxes, clothes dryers and fuel burning appliances draw air from the house to operate. You must provide adequate fresh air for these appliances. This will insure proper venting of vented fuel-burningappliances.

PROVIDING ADEQUATE VENTILATION

The following are excerpts from National Fuel Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation.

All spaces in homes fall into one of the three following ventilation classifications:

1.Unusually Tight Construction

2.Unconfined Space

3.Confined Space

The information on page 6 through 8 will help you classify your space and provide adequate ventilation.

Unusually Tight Construction

The air that leaks around doors and windows may provide enough fresh air for combustion and ventilation. However, in buildings of unusually tight construction, you must provide additional fresh air.

Unusually tight construction is defined as construction where:

a.walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of one perm (6 x 10-11 kg perpa-sec-m2)or less with openings gasketed or sealedand

b.weather stripping has been added on openable 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 wall-ceilingjoints, between wall panels, at penetrations for plumbing, electrical and gas lines and at other openings.

If your home meets all of the three criteria above, you must provide additional fresh air. See Ventilation Air From Outdoors, page 8.

If your home does not meet all of the three criteria above, proceed to Determining Fresh-Air Flow for Firebox Location, page 7.

Confined and Unconfined Space

The National Fuel Gas Code, ANSI Z223.1/ NFPA 54defines a confined space as a space whose volume is less than 50 cubic feet per

1,000 Btu per hour (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 cubic feet per 1,000 Btu per hour (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.

* Adjoining rooms are communicating only if there are doorless passageways or ventilation grills between them.

DETERMINING FRESH-AIRFLOW FOR HEATER LOCATION

Determining if You Have a Confined or Unconfined Space

Use this work sheet to determine if you have a confined or unconfined space.

Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways or ventilation grills between the rooms.

1.Determine the volume of the space (length x width x height).

Length x Width x Height =_______cu. ft. (volume of space)

Example: Space size 22 ft. (length) x 18 ft. (width) x 8 ft. (ceiling height) = 3168 cu. ft. (volume of space)

If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of the space.

2.Multiply the space volume by 20 to determine the maximum Btu/Hr the space can support.

_ _____ (volume of space) x 20 = (Maximum Btu/Hr the space can support)

Example: 3168 cu. ft. (volume of space) x 20 = 63,360 (maximum Btu/Hr the space can support)

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

_ _________ Btu/Hr (actual amount of Btu/Hr used)

Example: 63,360 Btu/Hr (maximum the space can support)

79,000 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 as follows:

A.Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 8.

B.Vent room directly to the outdoors. See

Ventilation Air From Outdoors, page 8.

C.Install a lower Btu/Hr heater, if lower Btu/ Hr size makes room unconfined.

If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconfined space. You will need no additional fresh air ventilation.

VENTILATION AIR

Ventilation Air From Inside Building

This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 3). You can also remove door into adjoining room (see option 3, Figure 2).

Follow the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilationfor required size of ventilation grills or ducts.

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Follow the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation for required size of ventilation grills or ducts.

IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a thermo-stat-controlledpower vent. Heated air entering the attic will activate the power vent.

INSTALLATION

Continued

IMPORTANT: Vent-freegas log heaters add moisture to the air.Although this is beneficial, installing firebox in rooms without enough ventilation air may cause mildew to form from too much moisture. SeeAir for Combustion and Ventilation, page 6.

IMPORTANT: Make sure firebox is level.

If firebox is not level, log set will not work properly.

Note: Your firebox is designed to be used in zero clearance installations. Wall or framing material can be placed against any exterior surface on the rear, sides, top or bottom of your firebox, except where standoff spacers are integrally attached. If standoff spacers are attached to your firebox, these spacers can be placed directly against wall or framing materials. Use the dimensions shown for rough opening to create the easiest installation.

Use dimensions shown for rough openings to create the easiest installation (see Built-In Firebox Installation, page 10).

INSTALLATION CLEARANCES

WARNING: Maintain the minimum clearances. If you can, provide greater clearances from floor, ceiling and adjoining wall.

Carefully follow these instructions. This will ensure safe installation.

Minimum Wall and Ceiling Clearances (see Figure 4)

A.Clearances from the side of fireplace cabinet to any combustible material and wall should follow diagram in Figure 4.

Example: The face of a mantel, bookshelf, etc. is made of combustible material and protrudes 31/2" from the wall. This combustible material must be 4" from the side of the fireplace cabinet (see Figure 4).

B.Clearancesfromthetopoffireboxopening to ceiling should not be less than 42".

C.When firebox is installed on carpeting or other combustible material, other than wood flooring, firebox should be installed on a metal or wood panel extending the full width and depth of enclosure.

D.Clearances from bottom of firebox to the

floor is 0".

These fireboxes can be installed as freestanding units against a wall with the approved,

optional cabinet mantels (see Accessories, page 17) or as abuilt-inunit. Clearances are the same for either installation method.

CAUTION: Do not install the firebox directly on carpet or vinyl.

Example

*

*Minimum 16" from Side Wall

Figure 4 - Minimum Clearance for Combustible to Wall

Mantel Clearances for Built-InInstallation

If placing custom mantel above built-infirebox, you must meet the minimum allowable clearance between mantel shelf and top of firebox opening shown in Figure 5, page 10. These are the minimum allowable mantel clearances for a safe installation. Use larger clearances wherever possible to minimize the heating of objects and materials placed on the mantel.

Notice: The firebox identificationlabel(includingmodelnumber, serial number, clearances, etc.) is located in the right side screen pocket area on the front of the firebox. See Figure 19, page 16.

Note: Appearance of firebox may vary depending on model.

Notice: If a log set is installed in the firebox, disconnect log set from gas supply and remove from firebox. Contact a qualified service person to do this.

There are two (2) blower accessory options for use in the vent-freefireboxes. Blower accessory models are BK and BK3. Model BK is a rotary squirrel cage type blower with magnetic attachment and variable speed control. The

BK3 is a triple fan blower system with an on/ off rocker switch.

The blower must be installed by removing the lower face panel and placing blower into its proper mounting position.

Decide which way you intend to gain access into the bottom rear of the firebox to install the blower accessory. The lower front panel can be removed easily by snapping out the front with a flat blade screwdriver. Use caution not to scratch any surfaces. Models with louvered front panels can also be removed by inserting fingertips between slots and gently pulling out. DO NOT FORCE. The panels are actually held in place by means of a retention dimple embossed on the edge of removable panels.

WARNING:Ifthereisaduplex electrical outlet installed in the right side of the bottom of the fireplace base area (see Figure 10), be sure that the electrical power to the outlet is turned off before proceeding with blower installation. Failure to do this may result in serious injury.
