A. LISTINGS AND CODE APPROVALS

The BW36 Series fireplace system has been tested and listed in accordance with the UL127 Standards, and has been listed by Underwriters Laboratories Inc. for installation and operation in the United States as described in these Installation & Operating Instructions.

The BW36 Series fireplaces have been tested and listed for use with the optional components given on page 4. These optional components may be purchased separately and installed at a later date. However, installation of an outside air kit will require significant reconstruction, and should be installed at the time of the initial fireplace installation.

Check with your local Building Code agency prior to installing this fireplace to ensure compliance with local Codes, including the need for permits and follow-upinspections. If any assistance is required during installation, please contact your local dealer or theHeat-N-GloTechnical Services Department, 20802 Kensington Blvd., Lakeville, MN 55044.

WARNING!

TO PREVENT CONTACT WITH SAGGING OR LOOSE INSULATION, THE FIREPLACE MUST NOT BE INSTALLED AGAINST VAPOR BARRIERS OR EXPOSED INSULATION. LOCALIZED OVERHEATING COULD OCCUR AND A FIRE COULD RESULT.

2. FRAMING THE FIREPLACE.

Figure 4 shows a typical framing (using 2 x 4 lumber) of the fireplace, assuming combustible materials are used. All required clearances to combustibles around the fireplace must be adhered to. Any framing across the top of the fireplace must be above the level of the hemmed edge along the top of the firebox assembly. Vertical framing at the side of the firebox assembly to which the side nailing flanges are attached must be

perpendicular to the face of the fireplace and may have point contact with the side of the fireplace at the nailing flange. A 1" air clearance must be maintained at the back and sides of the firebox assembly. Chimney Sections at any level require a two inch minimum air space clearance between the framing and chimney section.

Framing the Fireplace

Combustible Material. Material made of or surfaced with wood, compressed paper, plant fibers, plastics, or any material capable of igniting and burning, whether flame proofed or not, plastered or unplastered.

Non-combustibleMaterial.Material which will not ignite and burn. Such materials are those consisting entirely of steel, iron, brick, tile, concrete, slate, glass or plasters, or combination thereof.

Non-combustibleSealant Material.Sealants that

will not ignite and burn; General Electric RTV103Black, or equivalent. Rutland, Inc. Fireplace Mortar #63, or equivalent.

After completing the framing and applying the facing material (dry wall) over the framing, a non-com-bustible sealant,one-halfinch wide maximum, must be used to close off any gaps at the top and sides between the fireplace and facing to prevent cold air leaks.

Only non-combustiblematerials may be used to cover the black metal fireplace front.

WARNING!

DO NOT APPLY FINISHING MATERIALS OVER THE BOTTOM AIR INLET SLOTS NEAR THE GLASS DOOR OPENING ON THE FACE OF THESE FIREPLACES. THIS WILL BLOCK THE FLOW OF COOLING AIR AND MAY CAUSE DANGEROUSLY HIGH TEMPERATURES ON COMBUSTIBLE SURFACES OR ON THE FIREPLACE ITSELF.

3. HEARTH EXTENSIONS.

A hearth extension must be installed with all fireplaces. It is to protect the combustible floor in front of the fireplace from both radiant heat and sparks.

The construction of and materials used for a factorybuilt hearth extension are shown in Figure 5.

A hearth extension of this construction may be covered with any non-combustibledecorative material and may have a maximum thickness of 6" for the BW36 and 3” for the BW36C. Seal gaps between the hearth extension and the front of the fireplace with anon-combustiblesealant.

4. SIDEWALLS/SURROUNDS.

Adjacent combustible side walls must be located a minimum of 12" from the fireplace opening. See Figure 7. If you are using a decorative surround constructed of combustible material, it may be located within the shaded area defined in Figure 7. Short stub walls are also acceptable if they are contained within the shaded area.

5. MANTEL.

A combustible mantel may be positioned no lower than 12” above the top of the firebox opening. The combustible mantel may have a maximum depth of 12”. Combustible trim materials, projecting no more than 1 1/2” from the face of the fireplace, can be placed no closer than 6” from the top and side of the

firebox opening. (See the shaded areas on each side of the firebox, as defined in Figure 7). Combustible trim must not cover the black metal surfaces of the fireplace. This mantel clearance is in accordance with Section 7-3.3.3of ANSI/NFPA 211.

E. CHIMNEY REQUIREMENTS

When planning your fireplace location, the chimney construction and necessary clearances must be considered. The fireplace system and chimney components have been tested to provide the following flexibility in construction. The following figures are the minimum distances from the base of the unit.

Minimum overall straight height

14.5 ft.

Minimum height with Offset/Return

14.5 ft.

Maximum height

90 ft.

Maximum chimney length between an Offset/Return

Double Offset/Return minimum height

20 ft.

Maximum unsupported chimney length between Offset/Return

6 ft.

Maximum straight unsupported chimney height above firebox

1. USING OFFSETS AND RETURNS.

To bypass any overhead obstructions, the chimney may be offset using a 15° offset/return (SL315) or a 30° offset/return (SL330). Perform the following steps to determine the correct chimney component combination for your particular installation.

An offset and return may be attached together or a chimney section(s) may be used between an offset and return. However, the distance between two

elbows must never exceed 12 feet in total length.

a.Measure how far the chimney needs to be shifted to enable it to avoid the overhead obstacle. See Figure 8, dimension “A”.

b.After determining the offset dimension, refer to Table 1 (page 13) and find the “A” dimension closest to but not less than the distance of shift needed for your installation.

2. CHIMNEY HEIGHT REQUIREMENTS. (Above the roof line)

Major building codes specify a minimum chimney height above the roof top. These specifications are summarized in what is known as the “Ten Foot Rule”. This rule states: If the horizontal distance from the side of the chimney to the peak of the roof is 10 feet or less, the top of the chimney must be at least 2 feet above the peak of the roof, but never less than 3 feet in overall height above the highest point where it passes through the roof. See Figure 9.

If the horizontal distance from the side of the chimney to the peak of the roof is more than 10 feet, a chimney height reference point is established on the surface of the roof a distance of 10 feet from the side of the chimney in a horizontal plane. The top of the chimney must be at least 2 feet above this reference point, but never less than 3 feet in height above the highest point where it passes through the roof.

These chimney heights are necessary in the interest of safety and do not ensure smoke-freeoperation. Trees, buildings, adjoining roof lines, adverse wind conditions, etc., may create a need for a taller chimney should smoking occur.

DETERMINING THE NUMBER OF CHIMNEY SECTIONS REQUIRED.

To determine the chimney components needed to complete your particular installation, follow the below steps:

1.Determine the total vertical height of the fireplace installation. This dimension is measured from the base of the firebox assembly to the point where the smoke exits the terminal cap.

2.Subtract the height of the firebox assembly (3358") from the overall height of the fireplace installation.

3.Reference the below chart to determine what components must be selected to complete the fireplace installation.

4.Determine the number of firestop spacers, stabilizers, roof flashing, etc. required to complete the fireplace installation.

F. STEP-BY-STEPINSTALLATION OF THE FIREPLACE SYSTEM

WARNING!

BEFORE STARTING, DO THE FOLLOWING:

1.WEAR GLOVES AND SAFETY GLASSES FOR PROTECTION.

2.KEEP HAND TOOLS IN GOOD CONDITION. SHARPEN CUTTING EDGES AND MAKE SURE TOOL HANDLES ARE SECURE.

3.ALWAYS MAINTAIN THE MINIMUM AIR SPACE REQUIRED TO THE ENCLOSURE TO PREVENT FIRE.

STEP 1 - Positioning the Fireplace.

This fireplace may be placed on either a combustible or non-combustiblecontinuous surface. Follow the instructions for framing on page 9. Be sure to provide the minimum 1" air clearance at the sides and back of the firebox assembly. Framing that is perpendicular to the fireplace front may contact the side of the firebox assembly at the nailing flanges.

STEP 2 - Placing the Protective Metal Hearth

Strips.

Included with your fireplace are two metal hearth strips measuring approximately 26" x 4". These strips are used to provide added protection where the fireplace and hearth extension meet.

Slide the metal strips two inches under the front edge of the fireplace with the 2 pieces overlapping other in the middle of the fireplace to provide continuous coverage of the floor. See Figure 10.

STEP 3 - Leveling the Fireplace.

Level the fireplace side-to-sideandfront-to-back.Shim withnon-combustiblematerial, such as sheet metal, as necessary.

Important: To ensure proper fit of the glass doors, check the firebox opening for squareness. Measure diagonal distances of the opening to make sure they are equal. If they do not equal, continue to shim the firebox until those diagonals correspond.

Secure the fireplace by utilizing the nailing tabs located on either side of the fireplace to the vertical framing. Hold-downtabs are provided at the base of the firebox assembly for attachment to the subfloor if desired.

NOTE: Top Header may be positioned on the hemmed seam across the top of the firebox assembly.

STEP 4 - Assembling Chimney Sections.

Attach either a straight chimney section or an offset to the top of the fireplace depending on your installation requirement. When using offsets and returns, we highly recommend securing in place on the top of the fireplace with screws to permanently attach them to the top of the fireplace. See Figure 11.

When using elbows right off of the top of the unit, you will need to flatten the lances before you slip it on the collar. Once it is on, line it up and secure it with screws to the unit collar through the slots in the elbow.

CAUTION:

INNER FLUE AND OUTER LINER SECTIONS CANNOT BE DISASSEMBLED ONCE LOCKED TOGETHER. PLAN AHEAD TO INSURE THE PROPER INSTALLATION HEIGHT IS ACHIEVED WITH THE SELECTED CHIMNEY COMPONENTS.

These firestop spacers are designed to provide the minimum two inch air space required around the chimney. In all situations, the firestop spacers are to be nailed to the ceiling joists from the bottom or fireplace side, EXCEPT when the space above is an insulated ceiling or attic space. In this situation, the firestop spacer must be nailed from the top side to prevent loose insulation from falling into the required two inch air space around the chimney.

Figure 11

Offset Secured to Fireplace

NOTE: The inner flue is placed to the inside of the flue section below it. The outer casing is placed outside the outer casing of the chimney section below it. See Figure 12.

Figure 12

Connecting Chimney

Sections

STEP 5 - Preparing the Ceiling for Firestop Spacers.

Mark and cut out an opening in the ceiling for the particular firestop spacer being utilized (1412" x 1412" for an FS338, 1412" x 1834" for an FS339, or 1412" x 23" for an FS340). Frame the opening with the same dimension lumber used in the ceiling joists.

STEP 6 - Installing the Firestop Spacers.

Install the firestop spacer FS338 (Straight), FS339 (if a 15° offset located is in the ceiling joist area) or FS340 (if a 30° offset is located in the ceiling joist area). Nail the four [4] sides of the firestop spacer to the joists using a minimum of three [3] nails per side.

Firestop spacers must be used whenever the chimney penetrates a ceiling/floor area.

STEP 7 - Installing an AS8 insulation shield

An AS8 insulation shield should be installed when there is a possibility of insulation coming into contact with the factory-builtchimney system. The AS8 is installed by positioning it over the vertical chimney section where it penetrates an FS338 firestop spacer. The FS338 will support the AS8. See Figure 14 on page 16. When thefactory-builtchimney penetrates an insulated ceiling at either 15 or 30 degrees from vertical, an insulation dam should be constructed from plywood or sheet metal. A minimum 2" air space must be provided between the insulation dam and thefactory-builtchimney system.

STEP 8 - Double-checkingthe Chimney Assembly.

Continue assembling the chimney sections up through the firestop spacers as needed. While doing so, be aware of the height and unsupported chimney length limitations that are given on page 11 under “Chimney Requirements”.

Check each section by pulling up slightly from the top to ensure proper engagement before installing the succeeding sections. If they have been connected correctly, they will not disengage when tested.

STEP 9 - Securing the Chimney System.

When offsets and returns are joined to straight pipe sections, they must be locked into position with the screws provided, using the predrilled holes. To prevent gravity from pulling the chimney sections apart, the returns and the chimney stabilizers have straps for securing these parts to joists or rafters.

See Figure 15.

NOTE: Be sure to provide support for the pipe during construction and check to be sure inadvertent loading has not dislodged the chimney section from the fireplace or at any chimney joint.

WARNING!

WHEN CHIMNEY SECTIONS EXCEEDING SIX FEET IN LENGTH ARE INSTALLED BETWEEN AN OFFSET/ RETURN, STRUCTURAL SUPPORT MUST BE PROVIDED TO REDUCE OFF-CENTERLOADING AND PREVENT CHIMNEY SECTIONS FROM SEPARATING AT THE CHIMNEY JOINTS.

STEP 10 - Marking the Exit Point of the Roof.

Locate the point where the chimney will exit the roof by plumbing down to the center of the chimney. Drive a nail up through the roof to mark the center. See Figure 16.

STEP 12 - Assembling the Chimney Sections.

Continue to add chimney sections through the roof opening, maintaining at least a 2" air space.

STEP 13 - Installing Roof Flashing (optional).

If a roof flashing is to be used, install the roof flashing appropriate to the roof pitch and install a TR344 terminal cap (round) following the instructions shipped with these accessories.

STEP 14 - Installing an Outside Combustion

Air Kit.

The outside air damper assembly is factory installed on the left hand side of the firebox assembly. While its use is optional, it is highly recommended to minimize the effects of negative pressure within the structure. Figure 17 illustrates two of many possible methods that can be used to supply outside air to the fireplace system. To complete the outside air system install the AK22 Outside Air Kit according to the installation instructions supplied with the components.

NOTE: The outside air kit can terminate at any level with the exception that it must terminate at least three feet below the chimney terminal cap as shown in Figure 17.

STEP 15 - Completion of the Fireplace Enclosure.

Complete the fireplace enclosure, allowing space for outside air ducts and gas piping if desired. Electrical wiring should not come in contact with the unit. A minimum clearance of 1" must be maintained between the fireplace sides and the enclosure as well as the fireplace back and the enclosure. See Figure 4 for framing details.

STEP 16 - Provisions for an Optional Gas Log Set.

Knockouts are provided on both sides of the fireplace to allow for connection of a certified gas log lighter or a decorative gas appliance with a maximum input of 100,000 BTU/hr. incorporating an automatic gas shutoff device and complying with the Standard for Decorative Gas Appliances for Installation in Vented Fireplaces, ANSI Z21.60. The decorative gas appliance should be installed in accordance with the National Fuel Gas Code, ANSI Z223.1-1980.The side refractories are designed to allow 1/2” black pipe to pass through. Use anon-com-bustible sealant to seal any opening between the gas pipe and refractory on the inside. Repack the insulation removed, to seal around the gas pipe where it exits the side of the fireplace. A minimum1-1/2”air clearance must be provided to the 1/2” black pipe. See Figure 18.

This fireplace has been set up for installation of the gas pipe on the right hand side. If it is necessary to plumb the unit from the left hand side, remove the gas cover plate and gas tube from the right hand side of the unit and install on the left hand side. Cover the hole in the right hand side outer shell of the fireplace with the cover plate that covered the gas tube.

WARNING!

THIS FIREPLACE WAS NOT TESTED BY THE FIREPLACE MANUFACTURER FOR USE WITH AN UNVENTED GAS LOG HEATER. DO NOT INSTALL AN UNVENTED GAS LOG HEATER IN THIS FIREPLACE UNLESS IT HAS BEEN SPECIFICALLY TESTED AND LISTED BY UNDERWRITER’S LABORATORIES INC FOR USE IN THIS SPECIFIC MODEL FIREPLACE. UNLESS THE UNVENTED GAS LOG HEATER IS TESTED AND LISTED FOR USE IN THIS FACTORY-BUILTFIREPLACE, A FIRE HAZARD MAY BE CREATED THAT CAN RESULT IN A STRUCTURE FIRE.

STEP 18 - Installing the Firescreen.

Attach the firescreen to the fireplace side, utilizing the [2] hairpin clips in the columns. Use pliers to insert the clip through the last strand of screen wire and into the hole at the midpoint of the fireplace side.

STEP 19 - Installing the Glass Doors.

If desired, or required by local building codes, install the glass doors using the instructions supplied with the particular set of doors you have chosen.

STEP 20 - Positioning the Hearth Extension.

Position and secure the hearth extension over the protective metal strips that have been placed partially under the firebox front. See Figure 19. These strips should be protruding approximately two inches from under the fireplace front. Seal the crack between the hearth extension and fireplace with a non-com-bustible sealant.

STEP 21 - Applying Finishing Materials on the Hearth Extension.

Apply the non-combustiblefinishing material of your choice to the hearth extension.Do not install combustible materials over the black face of the fireplace This poses a safety hazard and may start a structure fire. You may only usenon-combustiblematerial over the black face of the fireplace. Refer to Figure 7 for combustible material information.

Do not cover or restrict any of the louvered openings on the front face of the BW36C Fireplace. Restricting or covering the louvered opening will create a safety hazard and may start a structure fire.

G. CONSTRUCTING A CHASE

A chase is a vertical box-likeenclosure built around the chimney and firebox. A chase may be constructed for the fireplace and chimney or for the chimney only. It is most commonly constructed on an outside wall.

In cold climates, it is recommended that the chase floor be insulated using batt type insulation between the floor joists.

Three examples of chase applications are shown in Figure 20.

1. Materials for the Chase.

The chase is constructed using framing materials much the same as the walls in your home. A variety of materials may be used including brick, stone, veneer brick, or standard siding materials.

In constructing the chase, several factors must be considered.

a.Maintain a 1" minimum air space around the firebox.

b.Maintain a 2" air space around the chimney.

c.The chase top must be constructed of a non-combustiblematerial.

d.In cold climates a firestop spacer should be installed in an insulated false ceiling at the 8 foot level above the firebox assembly. This prevents heat loss through the fireplace.

e.In cold climates, the walls of the chase should be insulated to the level of the false ceiling as shown in Figure 21. This will help prevent heat loss from the home around and through the fireplace.

WARNING!

DETAIL INSTRUCTIONS FOR INSTALLATION OF THE CHASE TOP, STORM COLLAR AND TERMINAL CAP ARE PACKAGED WITH THESE PARTS. TO AVOID DANGER OF FIRE, ALL INSTRUCTIONS MUST BE STRICTLY FOLLOWED, INCLUDING THE PROVISION OF AIR SPACE CLEARANCE BETWEEN CHIMNEY SYSTEM AND ENCLOSURE. TO PROTECT AGAINST AGAINST THE EFFECTS OF CORROSION ON THOSE PARTS EXPOSED TO THE WEATHER, WE RECOMMEND THAT THE CHASE TOP AND TERMINAL CAP BE PAINTED WITH A RUST RESISTANT PAINT.

2. Installing a Terminal Cap on a Chase Enclosed Chimney.

Construct a chase of desired materials maintaining a minimum 2" air space around the chimney.

WARNING!

NEVER INSTALL A SINGLE WALL SLIP SECTION OR SMOKE-PIPEIN A CHASE STRUCTURE. THE HIGHER TEMPERATURE OF THIS SINGLE WALL PIPE MAY RADIATE SUFFICIENT HEAT TO COMBUSTIBLE CHASE MATERIALS TO CAUSE A FIRE.

INSTRUCTIONS

NOTICE:

SAVE AND PASS THESE OPERATING INSTRUCTIONS AND THE INSTALLATION INSTRUCTIONS TO SUBSEQUENT OWNERS. THE INFORMATION PROVIDED IS INTENDED TO NOTIFY AND WARN THEM ABOUT MAKING UNSAFE FUTURE MODIFICATIONS SUCH AS THE ADDITION OF SHELVES OR THE USE OF UNAUTHORIZED PARTS AND REPAIRS.

CAUTION:

EDGES ARE SHARP! HAND PROTECTION IS RECOMMENDED.

This fireplace is intended to operate as a supplemental heat source for a single room. It is not designed to function as a primary heat source.

Fireplaces, as well as other woodburning appliances, have been used safely for many years. It has been our experience that most problems are caused by improper installation and operation of the unit. Make certain that installation and operation of the fireplace system is in accordance with these instructions.

It is extremely important that the fire be supervised whenever the fireplace is in use. It is also recommended that an annual inspection be performed on the fireplace system to determine if the flue system needs to be cleaned, or as in the case of any appliance, if minor repairs are required to maintain the system in top operating condition.

INTENDED USAGE. Thisfactory-builtfireplace is intended for use with either solid fuel (firewood) or a decorative gas appliance that has been tested and listed to the Standard for Decorative Gas Appliances for Installation in Vented Fireplaces, ANSI Z21.60.When operating your fireplace, the flue damper must be in the open position.

This fireplace was not tested and listed for use with an unvented gas log heater. Do not install an unvented gas log heater in this fireplace and operate it with the flue damper in the full closed position unless the unvented gas log has been specifically tested and listed for use in this fireplace by Underwriters Laboratories Inc. Use of an unvented gas log heater in this factory-buildfireplace may create a fire hazard that can result in a structure fire.

WARNING!

DO NOT OPERATE THIS FIREPLACE WITH THE FLUE DAMPER IN THE CLOSED POSITION. COMBUSTION PRODUCTS MUST VENT UP THE CHIMNEY SYSTEM TO PREVENT CARBON MONOXIDE POISONING, AND TO PREVENT HOT COMBUSTION GASES FROM CONTACTING AND OVERHEATING COMBUSTIBLE SURFACES. FAILURE TO OPERATE THIS FIREPLACE WITH THE DAMPER IN THE OPEN POSITION MAY RESULT IN ASPHYXIATION OR A STRUCTURE FIRE.

CAUTION:

FIREPLACE OPERATION DOES REQUIRE AIR. DO NOT TAKE AIR FROM OTHER FUEL BURNING APPLIANCES WHICH CAN RESULT IN IMPROPER VENTING (SMOKING) OR AIR DILUTION. ALWAYS PROVIDE ADEQUATE MAKE-UPAIR.

STARTING THE FIRE. Check the flue damper to be certain it is in the full open position. Place crumpled or twisted paper under the fireplace grate. Loosely arrange kindling or small pieces of wood to form a layer above the paper. Light the paper and add small pieces of wood until a hot bed of embers has been established. At this point add progressively larger pieces of wood until you are able to position 4” diameter split logs as shown in Figure 23.

When first lighting your fireplace, it may be necessary to pre-warmthe flue to establish a draft. This is done by holding a rolled up piece of burning newspaper under the flue damper for a few moments. This will prevent smoke spillage duringstart-up.

Sectional View of Fireplace

Firewood should be seasoned for at least 6 months before it can be burned as a fireplace fuel. Improperly seasoned (green or wet) wood will cause the fireplace to smoke, will allow creosote deposits to rapidly build-upin the chimney system and may cause roof stains to develop.

Fuel products with abnormal burning characteristics, including synthetic logs that contain wax binders, scrap lumber, wax or plastic coated cardboard and other highly volatile fuels that burn at excessive temperatures, may cause the fireplace to operate in an unsafe manner. Flammable liquid fuel are explosive and must never be used to start or freshen a fire. Heat-N-Glodoes not warrant the structural or functional performance of the fireplace system when such synthetic fuels or flammable liquids have been used.

NOTE: When heated for the first several times, the fireplace should be heated gradually to prevent moisture in the refractory from causing cracks and to allow binders in the insulation to dissipate. You will notice an industrial odor during the first few fires that are burned. This is considered to be normal.

Use only a solid wood fuel or a listed Heat-N-Glogas log set. Do not use a fireplace insert or products not specifically tested and listed for use in this fireplace.

Use common sense when burning this fireplace. The fire must be built on the fireplace grate, without danger of the burning fuel falling out of the firebox.

CAUTION:

NEVER USE GASOLINE, GASO- LINE-TYPELANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR SIMILAR LIQUIDS TO START OR ‘FRESHEN UP’ A FIRE IN THIS FIREPLACE. KEEP ALL SUCH LIQUIDS WELL AWAY FROM THE FIREPLACE WHILE IT IS IN USE TO AVOID THE RISK OF A HOSTILE FIRE.

DISPOSAL OF ASHES. Ashes should be placed in a metal container with atight-fittinglid. The closed container of ashes should be placed on anon-combustiblefloor 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 embers have thoroughly cooled.

GLASS DOORS. Most efficient fireplace operation using glass doors is with the doors open. When the doors are open, the screen must be closed. Only Hearth Technologies Inc. (HTI) glass doors, model numbers DM1036, DM1036A and DM1036B may be used on the BW36 Series fireplaces.

BW36 SERIES WOODBURNING FIREPLACE

WARNING!

FIREPLACES EQUIPPED WITH DOORS SHOULD BE OPERATED ONLY WITH DOORS FULLY OPEN OR FULLY CLOSED. IF DOORS ARE LEFT PARTIALLY OPEN, GAS AND FLAME MAY BE DRAWN OUT OF THE FIREPLACE OPENING, CREATING THE RISK OF BOTH FIRE AND SMOKE.

WARNING!

CONTINUED OVER-FIRINGCAN PERMANENTLY DAMAGE YOUR FIREPLACE SYSTEM. EXAMPLES OFOVER-FIRINGARE:

1.THE “NORMAL LOG FIRE” SHOULD BE CONTAINED IN THE GRATE, WITH THE LENGTH OF LOGS NO GREATER THAN THE BACK WALL OF THE FIREPLACE.

2.THE FOLLOWING MATERIALS MUST NOT BE USED IN THIS FIREPLACE: QUANTITIES OF SCRAP LUMBER, PINE BRANCHES, PROCESSED FIRE LOGS AND FIRE STARTERS, OR CARDBOARD BOXES WHICH EXCEED THE VOLUME OF THE “NORMAL LOG FIRE”. THESE MATERIALS PRODUCE MANY SPARKS AND MUST NOT BE USED.

Before starting a fire in your BW36 Series fireplace, use the following check list:

FLUE DAMPER. The flue damper is operated by moving a handle located in the fire chamber, which should place the damper in a fully open position. Pull the handle down to open, push the handle up to close. Verify this by looking up from the inside of the firebox. Always operate this fireplace with the damper fully open. Please note: down drafts, obstructions, damage or poor (wet) fuels can cause smoke spillage.

CHIMNEY INSPECTION. Visually inspect the chimney internally for obstructions and construction damage. Flue pipe joints and seams must be continuous and mechanically tight. In a used chimney, additional inspection is needed for creosotebuild-upwhich is the formation of a flammable sediment.

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-burningfire. 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 heating season to determine if creosote build-uphas occurred.

If creosote has accumulated, it should be removed to reduce the risk of a chimney fire.

CHIMNEY CLEANING. If you do detect abuild-upof creosote, contact a qualified chimney sweep or clean it yourself. To do this, perform the following steps:

1.Open the damper.

2.Hang a damp sheet across the fireplace opening to stop dirt and soot from entering the room.

3.Remove the Terminal Cap or Housing Top. See Figure 25.

4.Clean with a stiff nylon brush attached to a pole OR tie a rope to a burlap bag filled with straw and several small stones or sand. Work up and down the flue until clean.

5. Replace the terminal cap or housing top.

WARNING!

A CHIMNEY FIRE CAN PERMANENTLY DAMAGE YOUR CHIMNEY SYSTEM. THIS DAMAGE CAN ONLY BE REPAIRED BY REPLACING THE DAMAGED COMPONENT PARTS. CHIMNEY FIRES ARE NOT COVERED BY THE LIMITED WARRANTY AND BUYER PROTECTION PLAN.

CAUTION:

WHEN LEFT CLOSED WHILE BURNING YOUR FIREPLACE, FIRESCREENS AND GLASS DOORS WILL BE HOT. HANDLE WITH CARE.

CLEAR SPACE NEAR FIREPLACE. The hearth extension must extend at least 16 inches to the front and 8” to the sides of the firebox opening for the BW36 Series fireplace. Combustible materials must not be stored in this area. Combustible walls perpendicular to the front of the fireplace must be at least 12 inches from the fireplace opening. Room furnishings such as drapes, curtains, chairs, or other combustibles must be at least 4 feet from the open front of the fireplace.

GRATE. The factory installed integral grate must be used to hold the logs from falling out of an open fireplace and to allow air to pass between the burning logs. It is important to keep the fire off the hearth and to allow the ashes to collect beneath the fire, thereby forming a layer of additional heat protection. See Figure 23, page 21. Use only model number GR16 integral grate for replacement.

NEGATIVE AIR PRESSURE WITHIN THE STRUCTURE. This fireplace will operate correctly only if adequate ventilation is provided to allow proper draft to the fireplace system. Heat-N-Glo assumes no responsibility for the improper performance of the fireplace system caused by inadequate draft due to environmental conditions, downdrafts, tight sealing construction of the structure, or mechanical exhausting devices which create a negative air pressure within the structure where the fireplace is located.

OUTSIDE AIR. A damper control handle allows the individual control of the outside air inlets if your fireplace is equipped with this option. Use of outside air for combustion is highly recommended to conserve heated air within the structure and to provide make up air to keep the fireplace venting properly.
