Getting Started
A. Design and Installation Considerations
CAUTION
Check building codes prior to installation.
• Installation MUST comply with local, regional,
state and national codes and regulations.
• Consult insurance carrier, local building inspector,
fi re offi cials or authorities having jurisdiction about restrictions, installation inspection and permits.
When planning a fi replace installation, it is necessary to de­termine the following information before installing:
• Where the fireplace is to be installed. See Sections 3 and 4.
• The vent system confi guration to be used. See Sections 5 and 6.
• Gas supply piping. See Section 7.
• Framing and fi nishing details. See Sections 3 and 8.
• Whether optional accessories are desired. See Section 12.
Draft is the pressure difference needed to vent fi replaces successfully. Considerations for successful draft include:
• Preventing negative pressure
• Location of fi replace and chimney
WARNING
Asphyxiation Risk
Negative pressure can cause spillage of combustion fumes and soot. Fire needs to draft properly for safe operation.
B. Negative Pressure
Negative pressure results from the imbalance of air avail­able for the fi replace to operate properly. Causes for this imbalance 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: recessed lighting, attic hatch opening, duct leaks.
To minimize the effects of negative air pressure, the follow­ing must be considered:
• Install the outside air kit. Install the intake on the side of the house towards prevailing winds during the heating season.
• Ensure adequate outdoor air is supplied for combustion appliances and exhaust equipment.
• Ensure furnace and air conditioning return vents are not located in the immediate vicinity of the fi replace.
• Avoid installing the fi 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 due to stack effect. Stack effect creates negative pressure in lower levels. Hearth & Home Technologies recommends the use of direct vent fi replaces in basements.
Heatilator • ST42A • 35038 Rev G • 02/05

Page 6
Location of the fi replace and chimney will affect performance. As shown in Figure 2.1 the chimney should:
• Be installed through the warm airspace enclosed by the building envelope. This helps to produce more draft, especially during lighting and die-down of the fi re.
• Penetrate the highest part of the roof. This minimizes the effects of wind turbulence.
• Be located away from trees, adjacent structures, uneven roof lines and other obstructions.
Offsets can restrict draft so their use should be minimized. Consider the fi replace location relative to fl oor and ceiling and attic joists.

E. Construct the Chase
A chase is a vertical boxlike structure built to enclose the fi replace and/or its vent system. Vertical chimneys that run on the outside of a building may be, but are not required to 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.
Chases 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.
Building codes require false ceiling and fi restop spacers at each fl oor of the chase or every 10 ft (3.05 m) of clear space to control spread of fi re.
Walls, ceiling, base plate and cantilever fl oor at the fi rst level of the chase should be insulated. See Figure 3.5. Vapor and air infi 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 for maximum air tightness.
Gas line holes and other openings should be caulked with high temperature caulk or stuffed with unfaced fi berglass in­sulation. If the fi 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.
Two examples of chase applications are shown in Fig­ure 3.6.

• Wear protective gloves and safety glasses during installation.
A. Install the Outside Air Kit
The outside air kit is supplied as an optional feature with this fi replace and its use is highly recommended to minimize the effects of negative pressure within the structure. We recom­mend you utilize the shortest duct run to optimize the perfor­mance of the outside air kit. The outside air kit inlet should be positioned at least 4 ft (1.22 m) above the ground level, in a manner that will not allow snow, leaves, etc. to block the in­let. See Figure 4.1 for proper placement of outside air inlet.
The outside air kit is installed on either side of the fi replace. See Figure 4.2 for handle location/operation.

1 in. (25 mm) overlap
Metal strips are placed 2 in. (51 mm) under the front of the fireplace and must extend beyond the front and sides of fireplace by 2 in. (51 mm).
Figure 4.3 Position the Protective Metal Hearth Strips
Top piece must overlap
bottom piece
Included with your fi replace you will fi nd four metal hearth strips measuring approximately 28 in. x 4 in. (711 mm x 102 mm). These strips are used to provide added protection where the fi replace and the hearth ex­tensions meet.
Slide each metal strip 2 in. (51 mm) under the front edge of the fi replace. The individual pieces must over­lap each other by 1 in. (25 mm) minimum in the middle of the fi replace to provide continuous coverage of the fl oor. See Figure 4.3. These metal strips should extend from the front and sides of the fi replace opening by 2 in. (51 mm).
Note: When elevating the fi replace above the hearth exten­sion the front of the elevated platform must be protected with a protective metal hearth strip as shown in Figure 4.4.
• Level the Fireplace
Level the fi replace side-to-side and front-to-back. Shim with noncombustible material, such as sheet metal, as necessary. Secure the fi replace (using the nailing fl ang­es located on either side of the fi replace) to the vertical framing.

To determine the chimney components needed to complete your particular installation, follow the steps below:
• Determine the total vertical height of the fireplace installation. This dimension is measured from the base of the fi replace assembly to the point where the smoke exits the termination cap.
• Subtract the effective height of the fi replace assembly from the overall height of the fi replace installation (measured from the base of the fireplace to the bottom of the termination cap).
• Refer to Table 5.1 to determine what components must be selected to complete the fi replace installation.
• Determine the number of fi restop spacers, stabilizers, roof flashing, etc. required to complete the fireplace installation.
WARNING
Fire Risk
• Must maintain 2 in. (51 mm) air clearance to insulation and other combustible materials.

B. Using Offsets/Returns
To bypass any overhead obstructions, the chimney may be offset using a 30-deg (SL1130) offset/return.
An offset and return may be attached together or a chimney section(s) may be used between an offset and return.
Perform the following steps to determine the correct chim­ney component combination for your particular installation:
WARNING
Fire Risk
• Draft will be restricted if offset/returns greater than 30° are used.
Table 5.2
• Measure how far the chimney needs to be shifted to enable it to avoid the overhead obstacle. See Figure 5.3. Use dimension “A” to determine chimney section required to achieve the needed shift.
• After determining the offset dimension, refer to Table 5.2 and fi nd the “A” dimension closest to but not less than the distance of shift needed for your installation.
• The “B” dimension that coincides with the “A” dimension represents the required vertical clearance that is needed to complete the offset and return.
• Read across the chart and fi nd the number of chimney sections required and the model number of those particular chimney parts.
• Whenever the chimney penetrates a fl oor/ceiling, a fi restop spacer must be installed.
• The effective height of the fi replace assembly is measured from the base of the fi replace to the top of the starter collar. See Dimensions in Section 12.

OVERLAP
Figure 5.3 Chimney Offset/Return
Example: Your “A” dimension from Figure 5.3
is 14-1/2 in. (368 mm). Using Table 5.2 the dimension closest to, but not less than 14-1/2 in. (368 mm) is 14-5/8 in. (371 mm) using a 30° offset/return. It is then determined from the table that you would need 33 in. (838 mm) (Dimension “B”) between the offset and return. The chimney components that best fi t your application are two SL1112s.

C. Assemble the Chimney Sections
Attach either a straight chimney section or an offset to the top of the fi replace (depending on your installation require­ment). Chimney sections are locked together by pushing downward until the top section meets the stop bead on the lower section.
The inner fl ue is placed to the inside of the fl ue section below it. The outer casing is placed outside the outer casing of the chimney section below it. See Figure 5.4.
Note: The fi restop spacer MUST be nailed to the bottom of the ceiling joists EXCEPT when the space above is uninsulated and the attic insulation shield is not being used (see Figure 5.5). When the attic insulation shield is used the spacer may be above or below the joist of an insulated ceiling.

E. Install the Attic Insulation Shield
An insulation shield must be installed when there is a pos­sibility of insulation coming into contact with the factory built chimney system.
• Bend the tabs at the top of the attic insulation shield inward. This will help keep the chimney section centered in the shield.
• Position the shield over the vertical chimney section where it penetrates a fi restop spacer.
• Slide the shield down until it rests on the fi restop spacer. The fi restop spacer will support the insulation shield. See Figures 5.6 and 5.7.
WARNING
Fire Risk
• DO NOT pack insulation or other combustibles: between fi restops; between chimney and attic insulation shield.
• ALWAYS maintain specifi ed clearances around chimney and fi restop systems.
• Install fi restops as specifi ed.
Failure to keep insulation or other material away from chimney pipe may cause fi re.

F. Double-check the Chimney Assembly
Continue assembling the chimney sections up through the fi restop spacers as needed. While doing so, be aware of the height and unsupported chimney length limitations given under Section 5.A. 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.
G. Secure the Chimney
When offsets and returns are joined to straight pipe sections, they must be locked into position with the screws provided* (outer only), using the predrilled holes. To prevent gravity from pulling the chimney sections apart, the returns and the chimney stabilizers have hanger straps for securing these parts to joists or rafters. See Figure 5.8.
* or equivalent #6 or #8 sheet metal screw no longer than
3/4 in. (19 mm).

Operating Instructions
WARNING
Fire Risk
• Do not operate fireplace before reading and understanding operating instructions.
Failure to operate fi replace properly may cause fi re.
A. General Information
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 fi replace. Make certain that installation and operation of the fi replace system is in accordance with these instructions.
It is extremely important that the fi re be supervised when­ever the fi replace is in use. It is also recommended that an annual inspection be performed on the fi replace system to determine if the fl ue 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.
WARNING
HOT! DO NOT TOUCH. SEVERE BURNS MAY RESULT. CLOTHING IGNITION MAY RESULT.
Glass and other surfaces are hot during operation and cool down.
• Keep children away.
• CAREFULLY SUPERVISE children in same room as fi replace.
• Alert children and adults to hazards of high temperatures.
• Do NOT operate with protective barriers removed.
• Keep clothing, furniture, draperies and other combustibles away.
WARNING
Fire Risk
• For use with solid wood fuel or decorative gas appliance only.
• Do not install unvented gas logs.

B. Outside Air
A source of air (oxygen) is required in order for combustion to take place. Whatever air is consumed by the fi re must be replaced through cracks around windows, under doors, etc. Most newly constructed houses or existing homes fi tted with tightly sealed doors and windows are relatively air tight. In this case, an outside air source must be made available to feed combustion air from outside the home.
An outside air control handle allows you control of the out­side air inlet if your fi replace 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 fi replace venting properly.
This fi replace will operate correctly only if adequate ventila­tion is provided to allow proper draft to the fi replace sys­tem.
See Figure 9.1 for location and operation.
CAUTION
Outside air control handles are HOT. Adjust before lighting fi re.
C. Clear Space Near the Fireplace
Combustible materials must not be stored on the hearth ex­tension. Room furnishings such as drapes, curtains, chairs or other combustibles must be at least 4 ft (1.22 m) from the open fronts of the fi replace.
E. Firescreen
A fi rescreen is always provided to control sparks. It must be closed whenever the fi replace is in use. Glass doors or fi rescreens must not be used to hold burning material in­side the fi replace. Only those glass doors specifi cally tested and listed for use with the specifi c fi replace model should be used. Screens should be closed when the glass doors are closed.
WARNING
Fire Risk
Close fi rescreen when burning fi replace.
Do not use fi rescreen or glass doors to
hold burning material in fi replace.
Firescreen controls sparks. Glass may break or burning material may

G. Grate
The factory installed integral grate must be used to hold the logs from falling out of an open fi replace and to allow air to pass between the burning logs. It is important to keep the fi re off the hearth and to allow the ashes to collect beneath the fi re, thereby forming a layer of additional heat protection.
WARNING
Fire Risk
Use only factory installed integral grate.
May cause overfi re.
H. Wood Fuel
Firewood
Your fi replace performance depends on the quality of the fi rewood you use. All seasoned wood, regardless of spe­cies, contains about 8,000 BTU’s per pound, and hard­woods have a greater density than soft woods. A piece of hardwood will contain about 60% more BTU’s than an equal size piece of soft wood. Firewood is commonly sold by the cord (128 cu. ft.). A cord of seasoned oak (hardwood) would contain about 60% more potential en­ergy than a cord of seasoned pine (soft wood).
Examples of soft wood trees are Douglas fi r, pine, spruce, and cedar, poplar, aspen and alder. Soft woods require less time to dry, burn faster and are easier to ignite than hardwoods.
Examples of hardwood trees are oak, maple, apple, and birch. Hardwoods require more time to season, burn slower and are usually harder to ignite than soft woods.
The best wood fuel is a combination of soft wood and hardwood. Start the fi re with soft wood; the fi re will give off quick heat to bring the fi replace up to operating tem­perature, and then the hardwood can be added for slow, even heat and longer burn time.
Moisture
Regardless of which species of wood you burn, the single most important factor that effects the way your fi replace operates is the amount of moisture in the wood. The ma­jority of the problems fi replace owners experience are caused by trying to burn wet, unseasoned wood.
Freshly cut wood can be as much water as it is wood, having a moisture content of around 50%. Imagine a wooden bucket that weighs about eight pounds. Fill it with a gallon of water, put it in the fi replace and try to burn it. This sounds ridiculous but that is exactly what you are doing if you burn unseasoned wood.
Seasoning
Seasoned fi rewood is nothing more than wood that is cut to size, split and air dried to a moisture content of around 20%. The time it takes to season wood varies from around nine months for soft woods to as long as eighteen months for hardwoods. The key to seasoning wood is to be sure it has been split, exposing the wet interior and increasing the surface area of each piece. A tree that was 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.
The following guideline will ensure properly seasoned wood:
• Stack the wood to allow air to circulate freely around and through the woodpile.
• Elevate the woodpile off the ground to allow air circulation underneath.
• The smaller the pieces, the faster the drying process. Any piece over 6 in. (152 mm) in diameter should be split.
• Cover the top of the woodpile for protection from rain and snow. Avoid covering the sides and ends completely. Doing so may trap moisture from the ground and impede air circulation.
The problems with burning wet, unseasoned wood are twofold: First, you will receive less heat output from wet wood because it requires energy in the form of heat to evaporate the water trapped inside. This is wasted ener­gy that should be used for heating your home. Secondly, this moisture evaporates in the form of steam which has a cooling effect in your fi replace and chimney system. When combined with tar and other organic vapors from burning wood it will form creosote which condenses in the relatively cool fi replace and chimney.
WARNING
Fire Risk
Do NOT burn wet or green wood.
Store wood in dry location.
• Stack wood so both ends are exposed to air.
Wet, unseasoned wood can cause accumulation of creosote.
WARNING
Fire Risk
Do NOT store wood:
• Closer than required clearances to combustibles to fi replace.
• Within space required for loading or ash removal.

I. Starting a Fire
Check the fl ue damper to be certain it is in the full open po­sition. Place crumpled or twisted paper under the fi replace grate. Loosely arrange kindling or small pieces of wood to form a layer above the paper.
The fi res must be built on the fi replace grate, without danger of the burning fuel falling out of the fi replace opening.
Light the paper and add small pieces of wood until a hot bed of embers has been established.
After establishing the fi re bed, and the small fi rewood is burn­ing briskly, add a minimum of three average sized pieces of split fi rewood, place the wood in such a manner to allow combustion air and fl ames between them.
Note: When fi rst lighting your fi replace, it may be neces­sary to pre-warm the fl ue to establish a draft. This is done by holding a rolled up piece of burning newspaper under the fl ue damper for a few moments. This will help reduce smoke spillage during start-up.
Note: The fi rst three or four fi res should be of moderate size to allow the oils and binders to be burned from the fi replace and the refractory and paint to cure. You may notice an industrial odor the fi rst few fi res. This is consid­ered normal.
CAUTION
Odors and vapors released during initial operation.
• Curing of high temperature paint.
• Open windows for air circulation. Odors may be irritating to sensitive individuals.
WARNING
Fire Risk
Keep combustible materials, gasoline and other fl ammable vapors and liquids clear of fi replace.
• Do NOT store fl ammable materials close to the fi replace.
• Do NOT use gasoline, lantern fuel, kerosene, charcoal lighter fl uid or similar liquids to start or “freshen up” a fi re in this fi replace.
• Keep all such liquids well away from the fi replace while it is in use.
Combustible materials may ignite.

Troubleshooting
This fi replace will operate correctly only if adequate ventila­tion is provided to allow proper draft to the fi replace system. Hearth & Home Technologies assumes no responsibility for the improper performance of the fi replace system caused by inadequate draft due to environmental conditions, down drafts, tight sealing construction of the structure, or mechan­ical exhausting devices which will create a negative air pres­sure within the structure where the fi replace is located.
A. Understanding Vent Problems
If smoke spillage occurs from a fi replace opening when the door is open and the proper chimney height, fl ue size, and confi guration requirements for the installation have been met, there is either a leakage in the fl ue, a blockage in the

• Flue Leakage Check for improperly connected fl ue joints or a damaged
fl ue joint in the chimney system. Such leakage would reduce draft (air would be drawn in through the leaks rather than through the fi replace). The result might be diffi cult start-up and smoky fi res that might spill if other adverse draft conditions accompany this problem.
• Flue Blockage The damper should be open.

E. Limited Warranty
HEATILATOR WOODBURNING FIREPLACE
Limited Warranty
As part of its
20-YEAR BUYER PROTECTION PROGRAM
AS PART OF ITS 20 YEAR BUYER PROTECTION PROGRAM (“PROGRAM”), HEARTH & HOME TECHNOLOGIES INC. (“HHT”) is pleased to offer a Limited Warranty and a Replacement Parts Advantage covering specifi c components of your Heatilator®
woodburning fi replace system ( the “Fireplace”), installed in the United States of America or Canada. Dealers and employees of HHT have no authority to make any warranty or authorize any remedies in addition to or inconsistent with the terms of this Program.
Limited Warranty
HHT warrants the following components of your Heatilator woodburning fi replace to be free from original defects in material and workmanship
during the applicable periods described: fi ve years for the fi rebox assembly, chimney system and roof termination; two years for refractory fi rebox liners; and one year for the grate, wire mesh screens, fan system, outside air system, and glass doors. All limited warranty periods run from the date of initial installation of your Fireplace (the “Installation Date”). The Limited Warranty is subject to the conditions, exclusions and limitations of liability listed below.
Replacement Parts Advantage
Under HHT’s Replacement Parts Advantage, for a period of twenty years from your Installation Date of your Fireplace, if available, HHT will provide you with repair or replacement parts for defective components which are no longer under their applicable Limited Warranty, at 50% of the then current retail list price for such components. HHT shall have no responsibility for freight and labor charges related to such parts.
Conditions, Exclusions, & Limitations of Liability
A. Both the Limited Warranty and Replacement Parts Advantage supplied by HHT apply only while the Fireplace is in its location of original
installation. HHT’s obligation under this warranty does not extend to damages resulting from (1) installation, operation or maintenance of the Fireplace not in accordance with the Installation Instructions, Operating Instructions, and the Listing Agent Identifi cation Label furnished with the Appliance; (2) installation which does not comply with local building codes; (3) shipping, improper handling, improper operation, abuse, misuse, accident or unworkmanlike repairs; (4) environmental conditions, inadequate ventilation or drafting caused by tight sealing construction of the structure, air handling devices such as exhaust fans or forced air furnaces, or other causes; (5) use of fuels other than those specifi ed in the Operating Instructions; (6) installation or use of components not supplied with the Fireplace or any other components not expressly authorized and approved by HHT; and/or (7) modifi cation of the Fireplace not expressly authorized and approved by HHT in writing. This warranty is limited to only the component parts manufactured or supplied by HHT.
B. During the fi rst year of the Limited Warranty, HHT will, at its sole option, repair or replace any covered defective component and will provide
replacement parts at no charge. And will pay reasonable labor and freight costs. During the second through the fi fth years of the Limited Warranty (if applicable), HHT will provide replacement parts free of charge for any covered defective component, but will not pay for freight or labor costs related to the shipment of the parts or the actual repair or replacement. After the fi fth anniversary of the Installation date,
HHT’s sole obligation and your exclusive remedy is set forth in HHT’s Replacement Parts Advantage described above. In no event shall HHT be liable for any incidental or consequential damages caused by defects in your Fireplace.
C. 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 WARRANTY SPECIFIED ABOVE.
D. Some states do not allow exclusions or limitations of incidental or consequential damages, so those limitations may not apply to you. This
warranty gives you specifi c rights; you may also have other rights which vary from state to state.
