Warranty

Hearth & Home Technologies Inc.

LIMITED LIFETIME WARRANTY

Hearth & Home Technologies Inc., on behalf of its hearth brands (”HHT”), extends the following warranty for HHT gas, wood, pellet, coal and electric hearth appliances that are purchased from an HHT authorized dealer.

WARRANTY COVERAGE:

HHT warrants to the original owner of the HHT appliance at the site of installation, and to any transferee taking ownership of the appliance at the site of installation within two years following the date of original purchase, that the HHT appliance will be free from defects in materials and workmanship at the time of manufacture. After installation, if covered components manufactured by HHT are found to be defective in materials or workmanship during the applicable warranty period, HHT will, at its option, repair or replace the covered components. HHT, at its own discretion, may fully discharge all of its obligations under such warranties by replacing the product itself or refunding the verified purchase price of the product itself. The maximum amount recoverable under this warranty is limited to the purchase price of the product. This warranty is subject to conditions, exclusions and limitations as described below.

WARRANTY PERIOD:

Warranty coverage begins on the date of original purchase. In the case of new home construction, warranty coverage begins on the date of first occupancy of the dwelling or six months after the sale of the product by an independent, authorized HHT dealer/ distributor, whichever occurs earlier. The warranty shall commence no later than 24 months following the date of product shipment from HHT, regardless of the installation or occupancy date. The warranty period for parts and labor for covered components is produced in the following table.

The term “Limited Lifetime” in the table below is defined as: 20 years from the beginning date of warranty coverage for gas appliances, and 10 years from the beginning date of warranty coverage for wood, pellet, and coal appliances. These time periods reflect the minimum expected useful lives of the designated components under normal operating conditions.

WARRANTY CONDITIONS:

• This warranty only covers HHT appliances that are purchased through an HHT authorized dealer or distributor. A list of HHT authorized dealers is available on the HHT branded websites.

• This warranty is only valid while the HHT appliance remains at the site of original installation.

• Contact your installing dealer for warranty service. If the installing dealer is unable to provide necessary parts, contact the nearest HHT authorized dealer or supplier. Additional service fees may apply if you are seeking warranty service from a dealer other than the dealer from whom you originally purchased the product.

• Check with your dealer in advance for any costs to you when arranging a warranty call. Travel and shipping charges for parts are not covered by this warranty.

WARRANTY EXCLUSIONS:

This warranty does not cover the following:

• Changes in surface finishes as a result of normal use. As a heating appliance, some changes in color of interior and exterior surface finishes may occur. This is not a flaw and is not covered under warranty.

• Damage to printed, plated, or enameled surfaces caused by fingerprints, accidents, misuse, scratches, melted items, or other external sources and residues left on the plated surfaces from the use of abrasive cleaners or polishes.

• Repair or replacement of parts that are subject to normal wear and tear during the warranty period. These parts include: paint, wood, pellet and coal gaskets, firebricks, grates, flame guides, light bulbs, batteries and the discoloration of glass.

• Minor expansion, contraction, or movement of certain parts causing noise. These conditions are normal and complaints related to this noise are not covered by this warranty.

• Damages resulting from: (1) failure to install, operate, or maintain the appliance in accordance with the installation instructions, operating instructions, and listing agent identification label furnished with the appliance; (2) failure to install the appliance in accordance with local building codes; (3) shipping or improper handling; (4) improper operation, abuse, misuse, continued operation with damaged, corroded or failed components, accident, or improperly/ incorrectly performed repairs; (5) environmental conditions, inadequate ventilation, negative pressure, or drafting caused by tightly sealed constructions, insufficient make-up air supply, or handling devices such as exhaust fans or forced air furnaces or other such causes; (6) use of fuels other than those specified in the operating instructions; (7) installation or use of components not supplied with the appliance or any other components not expressly authorized and approved by HHT; (8) modification of the appliance not expressly authorized and approved by HHT in writing; and/or (9) interruptions or fluctuations of electrical power supply to the appliance.

• Non-HHT venting components, hearth components or other accessories used in conjunction with the appliance.

• Any part of a pre-existing fireplace system in which an insert or a decorative gas appliance is installed.

• HHT’s obligation under this warranty does not extend to the appliance’s capability to heat the desired space. Information is provided to assist the consumer and the dealer in selecting the proper appliance for the application. Consideration must be given to appliance location and configuration, environmental conditions, insulation and air tightness of

the structure.

This warranty is void if:

• The appliance has been over-fired or operated in atmospheres contaminated by chlorine, fluorine, or other damaging chemicals. Over-firing can be identified by, but not limited to, warped plates or tubes, rust colored cast iron, bubbling, cracking and discoloration of steel or enamel finishes.

• The appliance is subjected to prolonged periods of dampness or condensation.

• There is any damage to the appliance or other components due to water or weather damage which is the result of, but not limited to, improper chimney or venting installation.

LIMITATIONS OF LIABILITY:

• The owner’s exclusive remedy and HHT’s sole obligation under this warranty, under any other warranty, express or implied, or in contract, tort or otherwise, shall be limited to replacement, repair, or refund, as specified above. In no event will HHT be liable for any incidental or consequential damages caused by defects in the appliance. Some states do not allow exclusions or limitation of incidental or consequential damages, so these limitations may not apply to you. This warranty gives you specific rights; you may also have other rights, which vary from state to state. EXCEPT TO THE EXTENT PROVIDED BY LAW, HHT MAKES NO EXPRESS WARRANTIES OTHER THAN THE WARRANTY SPECIFIED HEREIN. THE DURATION OF ANY IMPLIED WARRANTY IS LIMITED TO DURATION OF THE EXPRESSED WARRANTY SPECIFIED ABOVE.

Operating Instructions

WARNING

HOT SURFACES!

Screen/mesh, glass doors and other surfaces are hot during operation AND cool down.

Hot screen/mesh and glass doors will cause burns.

• Do not touch screen/mesh or glass doors until cooled

• NEVER allow children to touch screen/mesh or glass doors

• Keep children away

• CAREFULLY SUPERVISE children in same room as  replace.

• Alert children and adults to hazards of high temperatures.

High temperatures may ignite clothing or other  ammable materials.

• Keep clothing, furniture, draperies and other  ammable materials away.

If you expect that children may come into contact with this  replace, we recommend a barrier such as a decorative screen. See your dealer for suggestions.

B. Seasoned Wood

Properly seasoned wood is important for successful operation of your replace. Most woodburning replace problems are caused by burning wet, unseasoned wood.

Seasoned rewood is wood that is cut to size, split and air dried to a moisture content of around 20%.

Imagine a wooden bucket that weighs about eight pounds. Fill it with a gallon of water, put it in the replace and try to burn it. This sounds ridiculous but that is exactly what you are doing if you burn unseasoned wood.

A tree cut down a year ago and not split is likely to have almost as high a moisture content now as it did when it was cut.

Please refer to Section 2.M. for more detail.

C. Starting a Fire

NOTICE: You must establish a good draft to prevent smoke spillage into the room.

WARNING! Risk of Fire! Keep combustible materials, gasoline and other ammable vapors and liquids clear of the replace.

DO NOT:

• store ammable materials close to the replace

• use gasoline, lantern fuel, kerosene, charcoal lighter uid or similar liquids to start or “freshen up” a re in this replace.

Keep all ammable liquids well away from the replace while it is in use. Combustible materials may ignite.

D. Grate

This replace is designed to be used with the grate supplied with this unit or one approved by HHT. The grate will deteriorate over time and will need occasional replacement.

WARNING! Risk of Fire! Use only the factory-supplied integral grate.

• Keeps logs in place.

• Allows proper air circulation around the re.

E. Firescreen

The rescreen is provided to control sparks. Keep it closed when the replace is in use.

WARNING! Risk of Fire or Burns!

• Screen will not prevent burning materials from falling out.

• Screen pulls or handles may be hot.

F. Flue Damper

• Refer to Figure 2.1 for location of control.

• Must be in fully open position (handle up toward the top of the replace) during operation of the replace.

• Before lighting the replace, verify fully open position by looking up from the inside of the replace.

WARNING! Risk of Fire and Asphyxiation! Open

damper prior to operating replace. A closed damper overres the replace and will cause smoke and ames to spill into the room.

• The rst three or four res should be of moderate size to allow the oils and binders to be burned from the replace and molded brick panel, and paint to cure. You may notice an industrial odor the rst few res. This is considered normal.

• Use well-seasoned wood (see Section 2.M.).

• Open the ue damper to a fully open position.

• Open outside air.

• Place crumpled or twisted paper under the replace grate.

• Loosely arrange kindling or small pieces of wood to form a ‘tent’ on the replace grate.

• Pre-warm the ue to establish a draft to help reduce smoke spillage during start-up. Hold a rolled up piece of burning newspaper under the ue damper for a few moments.

• Light the crumpled paper to ignite the kindling.

• Add small pieces of wood until a hot bed of embers has been established.

• Add a minimum of three average size pieces of split rewood, placed to allow combustion air and ames between them.

CAUTION! Odors and vapors released during initial operation may be irritating to sensitive individuals. Open

windows for air circulation.

Heatilator • Birmingham BIR42-B • 4059-681C • 9/12

G. Outside Air

• Refer to Figure 2.1 for location of controls.

• Outside air doors should be in the fully opened position during operation of the replace.

• Before lighting the replace, turn both handles & pull out to open. Reverse steps to close and lock.

H. Molded Brick Panel

• The molded brick panel is shipped separately, but required to contain heat and provide an attractive interior.

• It will deteriorate over time and will need occasional replacement. Small hairline cracks and discoloration are normal and do not affect its safety.

• Cracks in the mortar may occur and do not affect the safety of the unit.

• (See Molded Brick Panel Maintenance, Section 3.C.)

WARNING! Risk of Fire! DO NOT burn replace without molded brick panel. Use only molded brick panel supplied by Hearth & Home Technologies, Inc.

M. Wood Fuel

Hardwood vs Softwood

Your replace performance depends on the quality of the rewood you use.

• Seasoned wood contains about 8,000 BTUs per pound .

• Hard woods are more dense than soft woods.

• Hard woods contain 60% more BTUs than soft woods.

• Hard woods require more time to season, burn slower and are harder to ignite.

• Soft woods require less time to dry, burn faster and are easier to ignite.

• Start the re with soft wood to bring the replace up to operating temperature and to establish draft.

• Add hard wood for slow, even heat and longer burn time.

Soft woods Hard woods

• Douglas Fir • Oak

• Pine • Maple

• Spruce • Apple

• Cedar • Birch

• Poplar

• Aspen

• Alder

Seasoned Wood

• Cut logs to size

• Split to 6 in. (152 mm) or less

• Air dry to a moisture content of around 20%

- Soft wood - about nine months

- Hard wood - about eighteen months

NOTICE: Seasoning time may vary depending on drying

conditions.

Storing Wood

Steps to ensure properly seasoned wood:

• Stack wood to allow air to circulate freely around and through woodpile.

• Elevate wood pile off ground to allow air circulation underneath.

• Smaller pieces of wood dry faster. Any piece over 6 in. (152 mm) in diameter should be split.

• Wood (whole or split) should be stacked so both ends of each peice are exposed to air. More drying occurs through the cut ends than the sides.

• Store wood under cover to prevent water absorbtion from rain or snow. Avoid covering the sides and ends completely.

Moisture

WARNING! Risk of Fire!

• DO NOT burn wet or green wood.

• Wet, unseasoned wood can cause accumulation of creosote.

The majority of the problems replace owners experience are caused by trying to burn wet, unseasoned wood.

• Wet, unseasoned wood requires energy to evaporate the water instead of heating your home, and

• Evaporating moisture cools your chimney, accelerating formation of creosote.

WARNING! Fire Risk! DO NOT store wood:

• in front of the replace.

• in space required for loading or ash removal.

Processed Solid Fuel Firelogs

Manufactured relogs may be used with this replace. Hearth & Home Technologies Inc. recommends the use of UL Classied processed fuel relogs. Follow the manufacturer’s lighting and safety instructions.

Using relogs may require more frequent chimney inspection and cleaning.

Do not poke or stir the logs while they are burning. Use only relogs that have been evaluated for the application in manufactured replaces and refer to relog warnings and caution markings on packaging prior to use.

Maintenance and Service

A. Disposal of Ashes

Frequency: When they reach bottom of grate By: Homeowner

WARNING! Risk of Fire! Ashes could contain hot embers.

• Place ashes in a metal container with a tight-tting lid.

• The closed container should be placed on a noncombustible oor or on the ground, well away from all combustible materials, pending nal 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.

B. Chimney Inspection/Cleaning

Frequency: At least twice a year during heating season or

as recommended by a certied chimney sweep By: Certied chimney sweep

WARNING! Risk of Fire! Ignited creosote is extremely HOT. Prevent creosote buildup.

Refer to Figure 3.1 to remove/reinstall termination caps.

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 ue of a slow-burning re. As a result, creosote residue accumulates on the ue lining. When ignited this creosote makes an extremely hot re.

WARNING! Risk of Fire! A chimney re can permanently damage your chimney system and nearby structures.

In the event of a chimney re, Hearth & Home Technologies Inc. recommends

• replacement of the chimney, and

• inspection of the adjacent structure to the provisions of NFPA Level III inspection criteria

The chimney shall be inspected at least twice a year during the heating season to determine when a creosote buildup has occurred.

When creosote has accumulated it shall be removed to reduce the risk of a chimney re.

B. Design and Installation Considerations

D. Negative Pressure

NOTICE: Check building codes prior to installation.

• Installation MUST comply with local, regional, state and national codes and regulations.

• Consult insurance carrier, local building inspector, re ofcials or authorities having jurisdiction over restrictions, installation inspection and permits.

Before installing, determine the following:

• Where the replace is to be installed.

• The vent system conguration to be used.

• Gas supply piping.

• Framing and nishing details.

• Whether optional accessories are desired.

C. Draft

Draft is the pressure difference needed to vent replaces successfully. When a replace is drafting successfully, all combustion by-products are exiting the home through the chimney.

Considerations for successful draft include:

• Preventing negative pressure

• Location of replace and chimney

NOTICE: Hearth & Home Technologies assume s no responsibility for the improper performance of the replace system caused by:

• Inadequate draft due to environmental conditions

• Downdrafts

• Tight sealing construction of the structure

• Mechanical exhausting devices

• Improper positioning of the chimney in a not-recommended location on the roof.

WARNING! Risk of Asphyxiation! Negative pressure can cause spillage of combustion fumes and soot. Fire must draft properly for safe operation.

Negative pressure results from the imbalance of air available for the replace to operate properly. It can be strongest in lower levels of the house.

Causes include:

• Exhaust fans (kitchen, bath, etc.)

• Range hoods

• Combustion air requirements for furnaces, water heaters and other combustion appliances

• Clothes dryers

• Location of return-air vents to furnace or air conditioning

• Imbalances of the HVAC air handling system

• Upper level air leaks such as:

- Recessed lighting

- Attic hatch

- Duct leaks

To minimize the effects of negative air pressure:

• Ensure adequate outdoor air for all combustion appliances and exhaust equipment

• Ensure furnace and air conditioning return vents are not located in the immediate vicinity of the replace

• Avoid installing the replace near doors, walkways or small isolated spaces

• Recessed lighting should be a “sealed can” design

• Attic hatches weather stripped or sealed

• Attic mounted duct work and air handler joints and seams taped or sealed

• Basement installations should be avoided

NOTICE: The fireplace provides some outside air for combustion. Other methods may be necessary if more air is required.

NOTICE: Hearth & Home Technologies Inc. recommends the use of direct vent appliances in basements.

E. Locating your Fireplace & Chimney

Location of the replace and chimney will affect performance.

• Install within the warm air space enclosed by the building envelope. This helps to produce more draft, especially during lighting and die-down of the re.

• Penetrate the highest part of the roof. This minimizes the effects of wind loading.

• Locate termination cap away from trees, adjacent structures, uneven roof lines and other obstructions.

• Minimize the use of chimney offsets.

• Consider the replace location relative to oor and ceiling and attic joists.

• Take into consideration the termination requirements in Section 8 and Section 9.

NOTICE: Locating the replace in an area of considerable air movement can cause intermittent smoke spillage from replace. Do not locate replace near

• frequently open doors

• central heat outlets or returns

DO NOT install in a basement.

Heatilator • Birmingham BIR42-B • 4059-681C• 9/12

B. Using Offsets/Returns

• Use an offset/return to bypass overhead obstructions.

• An offset and return can be used as a single entity or separated by chimney section(s).

WARNING! Risk of Fire! DO NOT use offset/returns greater than 30°. Chimney draft will be restricted and could cause

overheating and re.

• Measure the shift needed to avoid the overhead obstruction. Refer to dimension A in Figure 8.3.

• Find the appropriate A dimension listed in Table 8.2.

• The B dimension coinciding with the A dimension measurement in Table 8.2 represents the required vertical clearance needed to complete the offset/return.

• Read across the chart to nd the number of chimney sections/model numbers needed between the offset and return.

Example:

Your “A” dimension from Figure 8.3 is 14 1/2 in. (368 mm). Using Table 8.2 the dimension closest to, but not less than 14 1/2 in. (368 mm) is 15 3/4 in. (400 mm) using a 30° offset/return.

You determined from the table that you would need 36 5/8 in. (930 mm) (Dimension “B”) between the offset and return.

1-1/4 in. (32 mm)

Heatilator • Birmingham BIR42-B • 4059-681C • 9/12

C. Assemble Chimney Sections

WARNING! Risk of Fire! DO NOT install substitute or damaged chimney components.

• Use only those components described in this manual.

Substitute or damaged chimney components could impair safe operation and cause overheating and re.

• Support the pipe during construction and check to be sure inadvertent loading has not dislodged the chimney section from the replace or at any chimney joint.

• Attach a straight chimney section or an offset to the top of the replace.

• Place inner ue to the inside of the chimney section below it. Place the outer casing outside the outer casing of the chimney section below it. Refer to Figure 8.4.

NOTICE: Chimney sections cannot be disassembled once

locked together. Plan ahead!

• Lock chimney sections and/or offsets/returns together by pushing downward until the top section meets the stop bead on the lower section.

• Pull on the top section to make sure it is fully engaged and will not separate.

• You may use #6 or #8 sheet metal screws no longer than 1/2 in. (13 mm) to fasten chimney sections together. Do NOT penetrate inner ue.

Figure 8.4 Assembling Chimney Sections

WARNING! Risk of Fire! You MUST use screws (pro-

vided) to fasten offset/returns to chimney sections to keep the chimney parts from twisting. Failure to do so could cause re.

• Fasten offset/returns to chimney sections. Insert the screws (provided) through the predrilled holes. Do NOT penetrate inner ue.

• Secure chimney returns with hanger straps (provided); fasten to studs or joists.

• Vertical straight runs of chimney must be supported every 35 ft (10.7 m).

Heatilator • Birmingham BIR42-B • 4059-681C• 9/12

D. Install Ceiling Firestops

ROOM ABOVE (non-insulated ceiling)

CAUTION! Risk of Fire! Ceiling restops must be used whenever the chimney penetrates a ceiling/oor.

• Chase construction requires ceiling restops at each oor or every 10 ft (3.05 m) of clear space.

• The ceiling restop slows spread of re and reduces cold air inltration.

• Install a ceiling restop whenever chimney penetrates ceiling/oor.

• Ma rk and c ut an ope ning in ceiling as shown in Figure 8.5.

• Frame the opening with the same size lumber used in the ceiling joists.

• Nail the ceiling restop to the bottom of the ceiling joists when there is a room above/

• Use an attic insulation shield if the ceiling is insulated. The ceiling restop may then be attached above or below the joists. Refer to Figure 8.6 and 8.7.

WARNING! Risk of Fire! DO NOT seal area between

restop opening and chimney pipe except where they enter the attic or leave the warm-air envelope of the home (use 600° F sealant).

E. Install Attic Insulation Shield

WARNING! Risk of Fire! You MUST install an attic in-

sulation shield when there is any possibility of insulation or other combustible material coming into contact with the chimney.

Bend inward

90°

Bend remaining tabs to rest against pipe to prevent insulation from falling in.

• DO NOT pack insulation between the chimney and

the attic insulation shield.

• Failure to keep insulation and other materials away

from chimney pipe could cause re.

• DO NOT offset chimney inside insulation shield.

Installation of a ceiling restop is required

• Refer to Figures 8.6 - 8.8.

• Roll the shield around the chimney (if chimney is already installed) until you have a 3 in. (76 mm) overlap and the three holes on each side match up (large holes on top).

• Insert three screws into the matching holes to form a tube.

• Bend three tabs on the bottom of the tube inward to 90° to maintain chimney air space as shown in Figure 8.6.

• Rest the insulation shield on the ceiling restop below.

• Bend the three short tabs at the top of the shield inward to 90° to maintain the 2 in. (51 mm) air space from the chimney.

• Bend the remaining top tabs to just meet the pipe.

If you wish to make a custom shield or barrier, follow these guidelines:

• Metal is preferred, although any material stiff enough to hold back the insulation can be used.

WARNING! Risk of Fire! Use of cardboard or other

materials that can deect under humidity or other environmental conditions is not recommended.

• The shield or barrier must be tall enough to extend above the insulation and prevent blown-in insulation from spilling into the cavity.

• The shield should be afxed to building structure.

• Maintain specied air spaces around chimney.

• Check instructions and local codes for further details.

• Measure opening on the horizontal; actual length may be larger depending on roof pitch.

• Cut out and frame opening.

• Refer to Chapter 25 of the Uniform Building Code for roof framing details.

G. Complete Installation

WARNING! Risk of Fire! You MUST maintain 2 in. (51 mm) air space to insulation and other combustible materials around the chimney system. Failure to do so could cause overheating and re.

• Keep chimney sections from separating or twisting.

• You may secure straight chimney sections at the joints with screws no longer than 1/2 in. (13 mm).

H. Install Flashing

• Slip the ashing over the chimney.

• Nail the ashing to the roof. Keep gaps between ashing plate and roof to a minimum.

NOTICE: Roong shingles must be below the ashing

plate on the lower side of a sloped roof and over the ashing plate on the sides and top.

• Caulk the ashing plate and roof junction as well as the vertical seam on the ashing. All nail heads must be caulked with a roong sealant.

A. Construct the Chase

A chase is a vertical boxlike structure built to enclose the replace and/or its vent system. Vertical chimneys that run on the outside of a building must be installed inside a chase.

Construction of the chase may vary with the type of building. These instructions are not substitutes for the requirements of local building codes. Local building codes MUST be checked.

A chase should be constructed in the manner of all outside walls of the home to prevent cold air drafting problems. The chase should not break the outside building envelope in any manner. All outer walls need to be insulated.

Building codes require false ceiling and ceiling restops at each oor of the chase or every 10 ft (3.05 m) of clear space to control spread of re.

Walls, ceiling, base plate and cantilever oor at the rst level of the chase should be insulated. See Figure 9.1. Vapor and air inltration barriers should be installed in the chase as per regional codes for the rest of the home. Additionally, Hearth & Home Technologies recommends that the inside surfaces be sheet rocked and taped (or the use of an equivalent method) for maximum air tightness.

Gas line holes and other openings should be caulked with high temperature caulk or stuffed with unfaced berglass insulation. If the replace is being installed on a cement slab, we recommend that in cold climates, a sheet of plywood or other raised platform be placed underneath to prevent conducting cold up into the room.

Three examples of chase applications are shown in Figure 9.2.

1. Fireplace and chimney enclosed in an exterior chase.

2. Chimney offset through exterior wall and enclosed in chase.

3. Chase constructed on roof.

Note: In cooler climates, all chase walls should be insulated.

WARNING! You must install false ceilings and ceiling restops at each oor of the chase or every 10 ft (3.05 m) to control spread of re.

WARNING! Risk of Fire! DO NOT seal area between restop opening and chimney pipe except where they enter the attic or leave the warm-air envelope of the home (use 600° F sealant).

WARNING! Risk of Fire! You must maintain a minimum 2 in. (51 mm) air space clearance to insulation and other materials surrounding the chimney system.

• Insulation and other materials must be rmly secured to prevent accidental contact with chimney system.

• Failure to prevent contact between insulation or other materials and chimney system may cause overheating and re.

G. Install Mortar (Optional)

The brick panels have been designed for

installation without the use of mortar being necessary. If the look of mortar is preferred, it is vaailable and can be installed. Follow the directions on the container for mixing.

The mortar can be applied with a mortar bag or

trowled on. Applying with mortar bag may be easiest and less messy. Clean sparingly as paint will rub off and may need to be touched up. Touch up paint is abailable as an accessory.

VERY IMPORTANT: Allow the mortar 72 hours to cure before operating the replace.



If Mortar is applied, it should be applied after finishing material is installed. Mortar will be applied between finishing materials and molded brick edges, bottom and sides.

The seam between finishing materials and firebox top must be sealed with noncombustible sealant.

H. Grate

• Install the grate if a gas log set is not going to be installed.

• Position the rear grate bar in the Grate Retainer.

• Position the top of the grate retainer over the rear grate bar and fasten in place with screw provided.

The noncombustible finishing material across the top of fireplace opening will be even with lower edge of metal face.

Noncombustible finishing materials MUST overlap side faces by 1 1/4 in. (32 mm) to cover the edges of the panels. Finished opening should be 42 x 38 in. (1067mm x 965 mm) to allow for door installation.
