Introduction
Bellfires® BCC
Early fireplaces were very inefficient, drawing a good deal of the heat up the chimney while admitting an unbearable amount of smoke into the room. In the late 1700’s, Benjamin Thompson, Count of Rumford, recognizing that a fireplace heats an area by radiation, began a series of experiments aimed at improving its performance.
He discovered through observations and various constructions that the exaggerated width of the chimney of his time, necessi­tated by the need for room for a chimney sweep to climb through the throat area into the flue, was a primary cause of inefficiency and smokiness. He attributed the problem not only to the chimney, but the width of the throat and also specific fireplace dimensions and configurations. Using the knowledge gained from his studies, Rumford modified the traditional fire­place design into one that burned cleaner and hotter and, most importantly, did not smoke. His efforts greatly improved the performance of the fireplace.
Later, in the 1900’s, a series of scientific experiments were conducted by Professor Peter O. Rosin, Dr. Ing., under the auspices of the British Coal Utilisation Research Association. The results are documented in his report, “The Aerodynamics of Domestic Open Fires”. Through the use of laboratory equip­ment, Dr. Rosin was able to observe air and smoke flow pat­terns and thus developed the ideal firebox and chimney shape for maximum efficiency. While expanding on Rumford’s work, some of Dr. Rosin’s findings varied dramatically from Rumford’s earlier theories; perhaps the most notable being the smoke shelf theory, shown diagrammatically at the left.
The important point of Dr. Rosin’s work is that it was per­formed in a scientific manner and pointed the way to a much more efficient and functional fireplace. Bell of England took this information and applied it to develop the Bellfire Fireplace, providing the ideal firebox and throat shape to guar­antee a smoke-free efficient fireplace capable of producing maximum radiant heat with minimum fuel. It was commonly used to heat the complete home until the second World War. Since then it has been further developed by using more mod­ern aerodynamic concepts and thermal insulation techniques
to improve the design.
Sleepy Hollow Chimney Supply has optimized the Bellfires® designs, and produced a superior radiant firebox combining advanced casting techniques and high temperature, high alu­mina ladle cast refractory. We feel confident that our Bellfires® units are the finest heat- producing open fireplaces to be found, whether used to upgrade old metal or masonry fireboxes or in new construction.
The Bellfires® Close Clearance (BCC) Wood Floor Fireplace makes available to homeowners, businesses, and restaurants the possibility of having a super efficient, heating fireplace in locations where a conventional masonry fireplace is not possi­ble. Suitable for new construction or renovation, the BCC requires no foundation or footings. The refractory firebox is designed in a half-pear shape in order to give it the greatest efficiency possible. The Bellfire® BCC refractory firebox, hearth, side flares, and smoke chamber, are enclosed in a heavy 20 gauge steel outer shell (ideal for installation in seizmic areas). The BCC 28’s pre-cast refractory firebox com­ponents are wrapped with ceramic insulation and the area between the firebox and outer steel cabinet is filled with perlite beads at the building site.
Using a pear shaped firebox design, proprietary thermal insu­lation technology, and meticulous metal fabrication found no where else, the BCC can be installed on a wood floor and posi­tioned within two (2) inches to combustible rear and side walls. BCC-28 Fireplace Models have been tested and found to be in compliance with UL 127-1988 and ULC S610-M93 “Standard for Factory-Built Fireplaces.” The Rumford style smoke chamber vents into any eight (8) inch diameter listed Type HT factory-built chimney that meets UL 1482 or ULC S627 standards. A top mounted round damper with a control key at the firebox level helps to prevent cold air from draining into an unused fireplace and help ensure a warm flue for instant draft. Super radiant heat output and thorough combustion pro­vide ample warmth and fuel efficiency that sets new standards for the open hearth. The refractory firebox stores heat and warms the house long after the flames have died out.

Safety Guidelines
A. Bellfires® fireplaces are not approved for use in mobile homes. B. There must be an air space clearance between the outermost portion of any section of the chimney system and
any combustible surface. Although two inches is a typical clearance, adhere to the requirements set forth by the chim­ney manufacturer. Combustible surfaces include: ceilings, joists, flooring, walls, electrical wiring, insulation and roof structures.
C. Never fill any required air space with insulation or other material. D. The chimney system must be vented to the outside. E. The chimney must extend at least three feet (900mm) above the roof and at least two feet (600mm) above any
portion of the roof within 10 feet (3m). F. Maximum chimney height from the top of the firebox to the top of the chimney should not exceed 40 feet when
supported solely by the fireplace, or 90 feet when resupported at or above 40 feet according to the chimney manufac­turer's resupport specifications.
G. Minimum chimney height from the top of the firebox to the top of the chimney must be 10 feet. H. The chimney must not be inclined more than 30 degrees from vertical. Greater angles result in hazardous
deposits of soot and ash in flue. I. A maximum of two offsets (4 elbows total) is allowed in a chimney. J. Firestops and joist shields must be used at each floor level through which the chimney rises. K. There should not be any forced air furnace registers in the room within ten feet of the fireplace. They can cause
negative pressure and create chimney down-drafts. L. Never mix parts of one chimney system with those of a different manufacturer. Do not install damaged chimney
parts. Remember, more fires are caused by chimneys than by solid-fuel appliances. M. Practice good workmanship. Sloppy work could jeopardize the safety of the installation.

LOCATE THE FIREPLACE
When planning the BCC installation, it is necessary to
a) Locate the fireplace, and b) Plan for framing the enclosure.
When selecting a location for the Bellfires® BCC fire­place in a planned or existing residence it is important to consider:
1) positioning of the fireplace with respect to air and traffic flow,
2) floor and surrounding walls,
3) ceiling joists and roof penetration.
Consider the impact on traffic flow in adjacent rooms and the position of forced air returns or registers near the proposed fireplace before deciding on the final location.
Snap chalk lines for enclosure and hearth extension
The Bellfires® BCC 28 must be installed on a flat, hard, level surface, such as a wood floor or raised platform.
CAUTION: The BCC must not be installed on carpet­ing, vinyl, or soft surface materials.
The location must be able to support the sustained weight of the BCC 28 fireplace (765 pounds) plus the chimney system, framing, sheathing, finish, and hearth protection.
Bellfires® may be installed against a combustible wall providing the two (2) inch minimum air is main­tained.
The figure above shows a typical installation view of an interior installation on an existing wall.

Page 13
By setting the Bellfires® BCC fireplace in the desired location in the room and using a plumb line, the position of a straight chimney above the fireplace can be simulated. Whenever possible, the BCC should be moved to minimize the cutting of ceiling joists and roof rafters or the use of chimney offsets.
Once the desired location is determined, the floor, wall, and ceiling should be marked for cuts and framing, rechecked, and any reframing at the ceil­ing and rafters can be done.
Plans for framing the enclosure should be thor­oughly checked. This is discussed more completely in the section on framing.

BCC 28 Assembly & Chimney Installation
The BCC 28 is designated for use with a listed Type HT pre-fab chimney that meet requirements from UL 1482 or ULC 5627
The Bellfires® BCC is the most advanced factory-built fireplace on the market today. Most factory-built fireplaces are light weight attempts at simulating a traditional masonry fireplace and only use simulated veneer fire brick in the firebox. They mistakenly continue to use a smaller rendition of the “tradi­tional” American fireplace firebox that is notoriously inefficient.
BCC 28 with firebox installation completed. Notice 2” ember guard extension projecting from beneath the front base of the Bellfires® shell.
Unlike them, Bellfires® BCCs use the same highly efficient refractory firebox used in all the Bellfires® masonry mod­els, from restoration designs to the new construction models, and houses them in a 20 gauge galvanized sheet metal shell that is the strongest, best built in the industry.
Bellfires® BCC fireplaces are unusual for factory builts in many ways. They are shipped with the refractory pieces boxed separately from the metal shell. The BCC is then assembled onsite. Following, on the next few pages, are the assembly instructions.

1. Once it is determined the exact place the fireplace will rest, place the supplied ” x 48” (12.5 mm x 122 cm) sheet of Cera-foil ceramic fibre blanket on wood floor, foil face up. (15-1) If the BCC is to be installed on a combustible floor lay the 20 gauge galvanized sheet metal protection (part # 6) on the floor over the ceramic insulation. (15-2) Again, if the BCC is being installed on a combustible floor and the hearth extension area in front of the fireplace is combustible extend excess width of the galvanized metal floor protection forward two (2”) inches (50mm), creating an ember guard at front edge of hearth and fireplace facing. (See 16-1 & 16-2 and the discussion on pgs. 16-17.)
2. Position metal fireplace shell(Part 1) in position at intended final location, properly centered over wood floor protec­tion. At this time double check alignment to insulated flue above, observing a two inch clearance to combustibles. (15-3)
3. Remove ” hex head screws in the top lid and front face panel of metal shell enclosure.(15-4) Shell should now be open and accessible to install the refractory components. (15-5)

Hearth Extensions
Combustible floors directly in front of the fireplace must be protected from sparks, embers, logs rolling out of the fireplace, and heat by using non-combustible floor protection–a hearth extension. The BCC 28 fire­place requires a minimum protection of 20” in front of the fireplace and 12” inches to each side of the fire-
place firebox opening for a total width of 672”. Local codes may require even larger dimensions. Total R value of the non-combustible hearth extension must be a minimum of R 2.2.
Be certain hearth extensions are securely fastened so they cannot be moved or easily dislodged and that they are constructed from durable, non-combustible materi­als such as brick, tile, slate, etc.
Ember Guards
In many areas ember guards are known as metal seal-
ing strips, or sheet metal bridges. Their function is critical in pre-fab fireplace installations. If a BCC 28 is installed on a combustible floor or a combustible raised hearth, or the hearth extension support is com­bustible, a metal ember guard strip with a minimum width of 4” and the full length of the BCC opening must be placed under the front of the BCC and extend­ed the same length to the front of the BCC. This is absolutely necessary to seal the crack between the BCC and the hearth extension so that embers, coals, sparks, or ashes cannot come in contact with combustibles in the area below. In raised hearth designs a special “Z” strip design will have to be constructed onsite. The Bellfires® Hearth Extension pad should be laid over the ember guard and cover the whole area of the hearth
extension, a minimum of 20” deep and 672” wide. Over this is placed the noncombustible finish hearth extension material–brick, tile, slate, etc. Finally, a bead of non-combustible material is used to seal the con­nection of hearth extension with the BCC.

How to determine if alternate floor protection materials are acceptable.
All floor protection materials must be non-combustible (i.e., metals, brick, stone, mineral fiber boards, etc.). Any organic materials (i.e., plastics, wood, paper products, etc.,) are combustible and must not be used. The floor protector specified may include some form of thermal designation such as R value (thermal resistance), k-factor (thermal conductivity), or C-factor (thermal conductance).
Procedure:
1) Convert specification to R-value: i. R-value given–no conversion needed. ii. K-factor is given with a required thickness (T) in inches: R = 1/k x T iii. C-factor is given: R = 1/C
2) Determine the R-value of the proposed alternate floor protector. i. Use the formuli in step (1) to convert values not expressed as “R”. ii. For multiple layers, add R-values of each layer to determine overall R-value.
3) If the overall R-value of the system is greater than the R-value of the specified floor protector, the alternate is acceptable.
EXAMPLE:
The specified floor protector should be w” thick material with a k factor of 0.84. The proposed alternate is 4” brick with a C-factor of 1.25 over 8” mineral board with a k-factor of .29.
Step (a): Use formula above to convert specification to R-value.
R = 1/k x T = 1/ .84 x .75 = .893
Step (b): Calculate R of proposed system.
4” brick of C = 1.25, therefore Rbrick = 1/C = 1/1.25 = .80 8” mineral board of k = .29, therefore Rmin. Bd. = 1/.29 x .125 = .431 Total R = Rbrick + Rmineral board = .8 = .431 = 1.231
Step (c): Compare proposed system R of 1.231 to specified R of .893. Since proposed system R is greater than
required, the system is acceptable.

Install a Listed HT UL1482 or ULC S627 Chimney
Depending on the existing framing limitations of the house either a straight or offset chimney will be installed. Bellfires® BCC fireplaces can be installed with any 8” Diameter Listed Type HT UL1482 or ULC S627 Chimney. Review the chimney manufacturer’s installation instructions for details and minimum requirements. Be sure to follow all instructions for the framing of openings in ceilings and floors, to provide firestopping in joist areas, and to install all proper firestop-spacer assemblies.
WHEN INSTALLING THIS FIREPLACE WITH A CHASE ABOVE THE ROOF
REFER TO THE CHIMNEY MANUFACTURER’S INSTRUCTIONS FOR CHASE CONSTRUCTION.
Maximum chimney height from the top of the Bellfires® BCC fireplace to the top of the chimney
should not exceed 40 feet when supported solely by the fireplace, or 90 feet when resupported
at or above 40 feet according to the chimney manufacturer’s resupport specifications.
It is the installer’s responsibility to provide the owner with a safe, fully operational venting system that meets
state or provincial and local codes. The majority of solid-fuel related fires are caused by chimney fires.

After the listed HT chimney has been installed, but before the chimney cap is placed, the BCC top mounted Spider Damper must be installed. The Spider Damper is placed in the top section of the listed HT chimney.
The Spider Drop-in Damper (25-1) (Part #21) installs typically like other top mounted dampers. The bottom hook-up is also typical. Attach the ring on the 28’ stainless cable (Part #22) to the underside ring of the Spider Damper. (25-2) The installer must go to the roof and place the Spider Drop-in Damper inside the top section of the type HT chimney until handles of damper don't go any further down. (25-3, 25-4) Unroll cable, dropping it all the way down the flue until cable reaches the firebox. The important installation step to be observed is as fol­lows: check for tightness in between flue walls and outside damper. Any air clearance should be sealed with flat gasket or silicone caulk. (25-5) Check damper plate to be sure it moves freely. Because blade is counterweight, damper should always be in the opening position.

The BCC 28 is different from most factory-built fireplaces in that the front facewall construction must be entirely non-combustible. Options include traditional brick or stone facewalls, providing the proper supports and fram­ing to carry such loads is built. Other possibilities include framing the facewall with metal studding and using expanded diamond mesh and plaster to achieve the look of finished sheet rock walls. Refer to the manufacturer’s installation guidelines for the metal studding you choose.
It is extremely important that the chase surrounding the BCC be ventilated. Minimum required opening size is 36” (914 mm) square at top and bottom. The openings may be on the front wall, side walls, or back wall. Two vents are sup ­plied with the BCC 28.

Top Down Burn
Handy Items to Have
A Fireplace Screen A Kindling Ax (Be careful) Stove Gloves An Ash Rake
Think of your fuel load as three component parts: The Base Course (can be unsplit if proper diameter) The Middle Course (split) The Top Courses (split finer)
THIS TYPE OF FIRE IS NOT RECOMMENDED FOR THE FIRST EIGHT TO TEN FIRES. BELLFIRES® MUST BE GRADUALLY BROKEN IN AND CURED WITH SMALL FIRES FOR THE FIRST EIGHT TO TEN FIRES.
DO NOT OVERFIRE YOUR BCC!! A fireplace grate is not necessary with the BCC 28. A
grate increases your critical burn rate allowing logs to burn faster than normal. Logs burn best in contact with hot firebrick in a bed of wood ashes.
Helpful Hints & Precautions before you start:
Make sure your fireplace and flue have been inspected for fire worthiness and are cleaned if found dirty (full of flammable cresosote), by a reputable Chimney Sweep. Make sure the damper is open. The damper is controlled from the keyed stainless cable and ring installed to either side of the firebox sidewall. Pull down and unhook to release the tension of the stain­less steel cable. Pull down and rehook the cable to close the damper. There are no other settings than completely open or completely closed. If your fire­place and flue are located on an outside wall or, when the damper is open, you feel a flow of frigid air rush­ing down into the room, pre-heat the flue with a sheet of lit newspaper. Hold the lit newspaper high into the damper area, wearing a pair of stove gloves for protec­tion. This will reverse the cold air plug present in the flue, creating a strong updraft with no smoke into your room. As soon as the newspaper is burned up, light your newspaper on top of your fuel load. Approximately 3-4 hours later when you have a nice bed of hardwood coals, use a fireplace rake to push the coals against the rear wall of the firebox. Next, lay your new logs, minimum of four, on top of the hot coals, lay the bottom two horizontally. The top two, a little short­er in length, place front to back approximately 3 inch­es apart creating a throat.
The greatest volume of smoke and particulate pollu­tion from a wood fire occurs during a cold start up.
Wood fires lit from the bottom, in a conventional man­ner, promote a dirty burn and waste a large amount of potential heat in the form of unburned gases.
A clean and efficient method for kindling a fire is a top burn. This almost forgotten ancient European tech­nique places the largest wood at the bottom in a criss cross crib fashion. As each tier is laid, the criss cross­ing becomes smaller. Kindling and a small amount of paper are placed on top and lit.
When the top burn fire is lit, the flames are always above the fuel load. The smoke and flammable gas from each tier of wood will always travel up through the flame and burn, thereby reducing particulate pollu­tion and unburned fuel.
A top kindling fire also produces large and less com­pacted glowing coals, providing excellent long-lasting radiant heat.
A top burn fire laid with seasoned hardwood to a height of eighteen to twenty-four inches will burn approximately four hours without adding additional wood. The fire will be mesmerizing as each tier slowly ignites and burns its way down.
TOP BURN RECIPE
Always start with dry, well-seasoned, split firewood and kindling. (Ideally seasoned firewood will have a 20% moisture content. The wood will show radial cracks at the ends and sound like bowling pins when beaten together.)
Bottom layer: Three good sized pieces of split hardwood five to six
inches thick, laid front to back. Second layer:
Three slightly smaller pieces of split firewood three to five inches thick, laid side to side.
Third layer: Four to five smaller pieces of split firewood two to three inches thick, laid front to back. Keep afternating and decreasing in size with split hardwood until they are about one inch thick.
Now alternate two rows with split softwood (pine, spruce, etc.) until pencil thick. Place a small piece of newspaper on top and light.

Operating Instructions & Maintenance
BCC Operating Instructions & Fireplace & Chimney Maintenance
Keep These Instructions
for Future Use
NEVER USE GASOLINE, GASOLINE-TYPE
LANTERN FUEL, KEROSENE, CHARCOAL-
LIGHTER FLUID, OR SIMILAR LIQUIDS TO
START OR “FRESHEN UP” A FIRE IN THIS FIRE-
PLACE. KEEP ALL SUCH LIQUIDS WELL AWAY
FROM THE FIREPLACEWHILE IT IS IN USE.
Use solid wood or processed
solid fuel firelogs only.
Do not poke or stir logs while they are burning.
Use only firelogs that have been evaluated for the application in fireplace and refer to firelog
warnings and caution markings on packaging
prior to use.
Beware of burning certain materials in your fireplace.
These items include plastic, poison ivy , and chemically
treated woods such as pressure-treated lumber, discarded
telephone poles, or railroad ties. These not only create air
pollution, they can induce extreme illness or irritation for
some individuals. Do not burn driftwood that has been in
the ocean or in salt water as the salt will corrode the chim-
ney. Do not abuse the fireplace by overfiring by burning
paper, cardboard, or construction materials such as
pressed wood, plywood, or lumber. Some fuels, such as charcoal, natural gas, etc., give off carbon monoxide when they burn. As this is a toxic gas you should insure that the
fireplace does not spill flue gas into the house.
Disposal of Ashes
Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a noncombustible floor or on the ground well away from all combustible materials pending final disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all cinders have thorough­ly cooled. Ashes should never be placed in a container with combustible materials.
Chimney Maintenance
CREOSOTE–Formation and Need for Removal
When wood is burned slowly it produces tar and other organic vapors which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow burning fire. As a result creosote residue accumulates on the flue lin­ing. When ignited this creosote makes an extremely hot fire.
The chimney should be inspected at least twice a year during the season to determine if creosote buildup has occurred.
If creosote has accumulated it should be removed to reduce the risk of a chimney fire.
Check the specific chimney manufacturer’s instruc­tions on removal of the chimney cap for chimney cleaning.
When the fireplace is first placed in use inspect the chimney frequently and clean the chimney anytime an accumulation of 8” thick or more is observed on the flue walls. The frequency of these inspections can be increased or reduced appropriately after a pattern of accumulation has been established. Please note how­ever that changes in the outside environmental condi­tions such as temperature and humidity, or changes in the operation of the fireplace can lead to rapid buildup of soot and/or creosote.
To clean the chimney obtain the services of a qualified and reputable chimney sweep or remove the accumula­tion with brushes on wooden, poly, or fiberglass poles. Do not use metal pipes, chains, wires, etc., to clean the chimney because such items can scratch the surface of the stainless steel flue which can shorten the life of the flue and provide a rough surface for soot particles to attach to.
In addition to checking and cleaning the chimney on a regular basis, be sure to inspect the chimney before starting a fire at the beginning of each heating season. Make sure the chimney is clear from any accumula­tion of soot, creosote, or any other debris and that all chimney joints are intact.

CONDITIONS OF WARRANTY
LIFETIME WARRANTY
Bellfires® Manufacturing Company extends the following warranty on the BCC 28, subject to the conditions of guarantee thereon. The fireplace is warranted for the lifetime of the original owner from the date of installation. If examination by the Bellfires® representative proves to our satisfaction that any part or portion of the fireplace is defective in material or workmanship, under normal use and service, such part or portion shall be replaced or repaired at no cost to you.
(A) Warranty may not be altered or extended by any of our dealers or agents, and except as provided herein, there are no other warranties. (B) Warranty does not cover damage resulting from misuse, abuse or accident. (C) Warranty shall be void if your unit is not operated in accordance with the oper­ation instructions provided at time of purchase and outlined below, or if the unit has been removed from the place in which it was originally installed. (D) Hairline cracking on the surface of refracto­ry components, a normal condition of use for refractory products, and/or cracking are expressly excluded from this warranty.
Important Instructions For Curing Refractory Fireplaces: (1) If the firebox has gotten wet, it must be dried slowly with a hair dryer or heat lamp before any fire is started. (2) The first eight fires must be built very small and well forward on the hearth so as not to contact the firebox. This will allow the unit to cure slowly by removing excess moisture in the refractory cavity behind the firebox, caused by the environment during storage or transportation, and mortar and materials used for installation. Proper curing eliminates the possibility of fracturing the firebox.
