California Safety Information

• WARNING
• This product and the fuels used to operate this product (wood), and the products of combustion of such fuels, can expose you to chemicals including carbon black, which is known to the State of California to cause cancer, and carbon monoxide, which is know to the State of California to cause birth defects or other reproductive harm. For more information go to: www.P65Warnings.ca.gov
• H. Smoke, CO Detectors & Safety Tips
• Smoke and CO Detectors
• The use of smoke and carbon monoxide (CO) detectors throughout the home is strongly advised, even if not required by building codes or insurance regulations. It is a good idea to install a smoke detector in the living areas and each bedroom. Follow the smoke/CO detector manufactures placement and installation instructions and maintain regularly.
• You may not, however, wish to install a detector in the immediate vicinity of the stove. Depending on the sensitivity of the unit, the alarm can be set off while you are tending the fire or emptying the ashes. If you install a detector in the same room, locate it as far away from the stove as possible.
• Safety Tips
• Conveniently locate a “Class A” fire extinguisher to contend with small fires. Be sure the fire extinguisher works and is clearly visible. All occupants of the house should know where it is, and how it operates. Have heavy stove gloves available near the stove. Have special safety accessories (e.g., Child Guard Screen) available for use if small children will be in the home.
• In the event of a stove pipe or chimney fire….
• Evacuate the house immediately
• Notify the fire department
• If the fire isn’t too threatening, closing down the stove tight, (damper, primary air, all doors) will help to smother the fire.
• Inspect your stove, vent pipe and chimney for any damage caused by the fire and correct any damage before using your stove again.

WARNING

• Fire Risk
• Do not leave the fire unattended when the door is unlatched
• Operate only with front doors and ash pan door closed.
•  Unstable firewood could fall out of the firebox creating a fire hazard to your home.

Getting Started

A. Design & Installation Considerations
Consideration must be given to:

• Safety
• Convenience
•  Traffic flow
• Chimney and chimney connector required
• It is a good idea to plan your installation on paper, using exact measurements for clearances and floor protection, before actually beginning the installation. If you are not using an existing chimney, place the appliance where there will be a clear passage for a factory-built listed chimney through the ceiling and roof.
• We recommend that a qualified building inspector and your insurance company representative review your plans before and after installation.
• If this appliance is in an area where children may be near it is recommended that you purchase a decorative barrier to go in front of the appliance. Remember to always keep children away while it is operating and do not let anyone operate this appliance unless they are familiar with these operating instructions.

• NOTE : Collar size is 6” (152mm) diameter (ID)

B. Hearth Protection Requirements

CAUTION

• Hearth and Home Technologies does not recommend adhesive based vinyl flooring due to thermal expansion. Floating-style flooring (LVP – luxury vinyl plank or LVT – luxury vinyl tile) can be used, but it will reach temperatures up to 110 °F in a room with ambient temperature of 70 °F. Consult flooring specifications to ensure compatibility.

• HHT recommends wood stoves and inserts have 57 inches of alternative flooring in front of the stove before using LVP/LVT regardless if they sit flush on the floor or are elevated on a raised hearth.

• For all other flooring, continue to follow clearance to combustible requirements in the installation manual.

• NOTICE : Clearances that do not meet the minimum guidelines could result in damage or buckling to the vinyl flooring and is done at the installer’s risk.

• The floor area directly under and around the stove will require protection from stray sparks or embers that may escape the firebox. Type 1 hearth pad with no additional “R” value is required.

• Use a noncombustible floor protector such as 1/4” non-asbestos mineral board or equivalent, or 24 gauge sheet metal. The floor protector may be covered with a noncombustible decorative material if desired. Do not obstruct the space under the heater.
  Protection requirements vary somewhat between the United States and Canada as follows:

• U.S. Installations: Non-combustible floor protection is required under the stove and must extend at least 16” from the front of the door opening and 8” from the sides of the door opening. (C, Figure 3.4)

• Canadian Installations: Non-combustion floor protection is required under the stove and must extend at least 18” from the front of the stove and 8” from the sides of the stove. It must also extend under the chimney connector and 2” to either side of any horizontal runs. (A, Figure 3.4)

• Note: For US installations, floor protection dimensions are measured from the door opening of the unit. For Canadian installations, all dimensions are measured from the sides and front of the unit.

Floor Protection Requirements

| U.S.| Canada
A| 8″| 8″ [203 mm]
B| 16″| 18″ [457 mm]
C| 8”| 8″ [203 mm]
D| 40”| 50″ [1270 mm]
E| 25-1/2″| 31″ [787 mm]

Figure 3.4 – These dimensions are minimum requirements only. Use greater dimensions whenever possible.

Fireplace Hearth Protection

• For all fireplace installations, follow the floor protection guidelines described above.
• Keep in mind that many raised hearths will extend less than the required clearance from the front of the heater when it is installed. In such cases, sufficient floor protection as described above must be added in front of the hearth to satisfy the minimum floor protector requirement from the front of the stove: 16” (406 mm) from the front in the United States and 18” (457 mm) from the front in Canada.
• Hearth rugs do not satisfy the requirements for floor protection as they are only fire-retardant, not fire proof.
• Fireplace installations also have special clearance requirements to the side walls, side decorative trim and fireplace mantel. Refer to the information on fireplace and mantel trim shields in this section.

C. Clearances To Combustibles

• Note : It is recommended that you have the unit in place for proper measurements and installation.
• NOTE : Double wall pipe clearances are for US installations ONLY. Canadian installations must conform with local code. In the absence of local codes you must comply with the ULC S627-00 and CAN/CSA-B365.

Figure 3.7

• Fireplace Clearances:
• A fireplace installation requires special clearance between the side of the stove and the right and left walls, the side of the stove and the decorative side trim on the fireplace face, and the top of the stove and the mantel.
• Maximum Mantel depth (A, Figure 3.8) of a combustible mantel is 9” (230 mm). At that depth, the clearance to the stove top (B) must be a minimum of 22-1/2″ (572 mm).
• Top Trim (C) protruding less than 1-1/2″ (38 mm) from the face of the fireplace must be a minimum of 12″ (305 mm) from the stove top. This clearance may not be reduced by shielding.
• For every 1-1/2″ (38 mm) increment that the trim or mantel extends in depth, the clearance from the stove top must also be increased by 1-1/2″ (38 mm).
• Side Trim must have a minimum clearance of 8″ (203 mm), measured from the stove’s top edge. (D, Figure 3.9)

When:

• A = 9″ (229 mm) Max.
• B = 22-1/2 (572 mm) Min.
• A = 7-1/2″ (191 mm) Max. B = 21″ (533 mm) Min.
• A = 6″ (152 mm) Max.
• B = 19-1/2″ (495 mm) Min.
• A = 4-1/2″ (114 mm) Max. B = 18″ (457 mm) Min.
• A = 3″ (76 mm) Max.
• B = 16-1/2″ (419 mm) Min.
• A = 1-1/2″ (38 mm) Max. B = 15″ (381 mm) Min.

Figure 3.8 – Mantel and trim clearances.

D. Locating Your Appliance & Chimney
Location of the appliance and chimney will affect performance. As shown in Figure 3.10 the chimney should:

• Install through the warm space enclosed by the building envelope. This helps to produce more draft, especially during lighting and die down of the fire.
• Penetrate the highest part of the roof. This minimizes the affects of wind turbulence and down drafts.
• Consider the appliance location in order to avoid floor and ceiling attic joists and rafters.
• Locate termination cap away from trees, adjacent structures, uneven roof lines and other obstructions.

Your local dealer is the expert in your geographic area and can usually make suggestions or discover solutions that will easily correct your flue problem.

E. Chimney Termination Requirements
Follow manufacturer’s instructions for clearance, securing flashing and terminating the chimney. Figures 3.11 & 3.12.

• Must have an approved and Listed cap
• Must not be located where it will become plugged by snow or other material
• Must terminate at least 3 feet (91 cm) above the roof and at least 2 feet (61 cm) above any portion of the roof within 10 feet (305 cm).
• Must be located away from trees or other structures NOTICE:
• Chimney performance may vary.
• Trees, buildings, roof lines and wind conditions affect performance.
• Chimney height may need adjustment if smoking or overdraft occurs.
• NOTICE: Locating the appliance in a basement or in a location of considerable air movement can cause intermittent smoke spillage from appliance. Do not locate appliance near
  • Frequently open doors
  • Central heat outlets or returns

F. Chimney Location (2-10-3 Rule)

• These are safety requirements and are not meant to assure proper flue draft.
• This appliance is made with a 6” (152 mm) diameter chimney connector as the flue collar on the appliance.
  • Changing the diameter of the chimney can affect draft and cause poor performance.
  • It is not recommended to use offsets and elbows at altitudes above 4000 feet above sea level and or when there are other factors that affect flue draft.

Chimneys & Venting

A. Venting & Draft Management

• A stove is part of a system, which includes the chimney, the operator, the fuel, and the home. The other parts of the system will affect how well the stove works. When there is a good match between all the parts, the system works well.

• Wood stove or insert operation depends on natural (unforced) draft. Natural draft occurs when the exhaust is hotter (and therefore lighter) than the outdoor air at the top of the chimney. The bigger the temperature difference, the stronger the draft. As the hot gases rise through the chimney they provide suction or ‘draw’ that pulls air into the stove for combustion. A slow, lazy fire with the stove’s air inlets fully open indicates a weak draft. A brisk fire, supported only by air entering the stove through the normal inlets, indicates a good draft. The stove’s air inlets are passive; they regulate how much air can enter the stove, but they don’t move air into it.

• Depending on the features of your installation – steel or masonry chimney, inside or outside the house, matched to the stove’s outlet or oversized – your system may warm up quickly, or it may take a  while to warm up and operate well. With an ‘airtight’ stove, one which restricts the amount of air getting into the firebox, the chimney must keep the stove’s exhaust warm all the way to the outdoors in order for the stove to work well. Some chimneys do this better than others. Here’s a list of features and their effects.

• Note: Elbow and Tee’s reduce the draft of a chimney system. Design the installation to minimize changes in direction. No more than 2 tee’s or elbows may be used.

• Masonry Chimney

• Masonry is a traditional material for chimneys, but it can perform poorly when it serves an ‘airtight’ stove. Masonry is a very effective ‘heat sink’ – it absorbs a lot of heat. It can cool the chimney gases enough to diminish draft. The bigger the chimney, the longer it takes to warm up. It’s often very difficult to warm up an outdoor masonry chimney, especially an oversized one, and keep it warm enough to maintain an adequate draft.

• Steel Chimney

• Most factory-made steel chimneys have a layer of insulation around the inner flue. This insulation keeps the chimney warm. The insulation is less dense than masonry, so a steel chimney warms up more quickly than a masonry chimney. Steel doesn’t have the good looks of masonry, but it performs much better.
  Indoor/Outdoor Location

• Because the chimney must keep the smoke warm, it’s best to locate it inside the house. This uses the house as insulation for the flue and allows some heat release into the home. An indoor chimney  won’t lose its heat to the outdoors, so it takes less heat from the stove to heat it up and keep it warm.

• Single Venting

• Each ‘airtight’ stove requires its own flue. If an airtight stove is vented to a flue that also serves an open fireplace, or a leakier stove, it’s easier for the chimney draft to pull air in through those channels and performance of the stove suffers. Imagine a vacuum cleaner with a hole in the hose to understand the effect here. In some cases the other appliance can even cause a negative draft through the stove, and result in a dangerous draft reversal.

• Draft

• The Vermont Castings Aspen C3 requires a minimum draft of 10 Pa or .04” of W.C. Draft too low can cause low heat output and a sluggish burn. Draft higher than 30 Pa or .12 of W.C. can result in short burn times and overfiring. Ensure the draft
  of the chimney is in correct range for operating the Aspen C3.

• Flue Sizing

• The inside size of a chimney for an ‘airtight’ stove should match the size of the stove’s flue outlet. When a chimney serves an airtight stove, more is not better; in fact, it can be a disadvantage. Hot gases lose heat faster as they travel slower through a chimney; if we vent a stove with a six-inch flue collar (28 square inch area) into a 10 x 10″ flue, the gases slow to one third their original speed. This allows the gases to cool more rapids, which weakens draft strength. If an oversized flue is also outside the house, the heat it absorbs gets transferred to the outdoor air and the flue usually stays cool.

• It is common for a masonry flue, especially one serving a fireplace, to be oversized for the stove. It can take quite a while to warm up such a flue, and the results can be disappointing. The best solution to an oversized flue is an insulated steel chimney liner, the same diameter as the stove or inserts flue outlet; the liner keeps the exhaust warm, and the result is a stronger draft. An non-insulated liner is a second choice – the liner keeps the exhaust restricted to its original size, but the hot gases still must warm up the air around the liner. This makes the warm-up process take longer.

• Pipe & Chimney Layout

• Every turn the exhaust must take as it travels to the chimney top will slow it down. The ideal pipe and chimney layout is to vent vertically into a completely straight and vertical chimney. If you are starting from scratch, use this layout if possible. If the stovepipe must elbow to enter a chimney, locate the thimble about midway between the stove top and the ceiling. This achieves several goals: it allows the gases to speed up before they must turn, it leaves some pipe in the room for heat transfer, and it gives you long-term flexibility for installing a different stove without relocating the thimble.

• There should be no more than eight feet of single-wall stove pipe between the stove and a chimney; longer runs can cool the exhaust enough to cause draft and creosote problems. With prefabricated chimney, bring it down to six to eight feet from the stove. With a masonry chimney, arrange the pipe so that it turns into the chimney within eight feet of the stove.

• B. Venting Components

• Chimney Connector: It is also known as flue pipe or appliance pipe. The chimney connector joins the appliance to the chimney. It must be a 6” (152 mm) minimum diameter 24 gauge mild steel black or 26 gauge blued steel, or an approved air-insulated double wall venting pipe.

• Thimble: A manufactured or site-constructed device installed in combustible walls through which the chimney connector passes to the chimney. It is intended to keep the walls from igniting. Site constructed thimbles must meet NFPA 211 Standards. Prefabricated must be suitable for use with selected chimney and meet UL103 Type HT Standards. Follow instructions provided by the manufacturer for manufactured thimbles for masonry chimney and prefabricated chimneys.

• Chimney: The chimney can be new or existing, masonry or prefabricated and must meet the following minimum requirements specified in section 4C “Chimney Systems”.
