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.

• The rst three or four res should be of moderate size to

allow the oils and binders to be burned from the replace and the molded brick panels, 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.

• 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.

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.

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.

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.

Maintainance 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.

C. Check Firebox Molded Brick Panel

Frequency: After each ash removal By: Homeowner

WARNING! Risk of Fire! Inspect replace molded brick panel. Crumbling, deteriorated molded brick panel can allow overheating of surrounding materials.

Expansion and contraction will cause minor cracking of the molded brick panel. This is normal. The panels will require periodic replacement depending on use.

The panels should be replaced if

• Cracks exceed ¼ inch (6 mm) in width,

• Metal is exposed behind the panels,

• Large pieces of panel fall out.

NOTICE: Do not substitute for HHT mortar. Other materials may stain the molded brick panels.

D. Inspect Grate

Frequency: After each ash removal By: Homeowner

Inspect grate for:

• Warping or sagging 1-1/2 in. (38 mm) or more

• Broken welds

• Burn-through of grate bars For safe operation, replace only with the approved grate

from Hearth & Homes Technologies Inc.

E. Glass Cleaning

Frequency: As desired By: Homeowner

CAUTION! Handle glass assembly with care. Glass is breakable.

• Avoid striking, scratching or slamming glass

• Avoid abrasive cleaners

• Do not clean glass while it is hot

Clean glass with a non-abrasive commercially available cleaner or ashes:

• Light deposits

- Use household glass cleaner

• Heavy deposits

- Use wood ash on damp cloth or,

- Use commercial replace glass cleaner (consult with your dealer)

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 airspace 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.

A MAJOR CAUSE OF VENT RELATED FIRES IS FAILURE TO MAINTAIN REQUIRED CLEARANCES (AIR SPACES) TO COMBUSTIBLE MATERIALS. IT IS OF THE UTMOST IMPORTANCE THAT DURACHIMNEY II BE INSTALLED ONLY IN ACCORDANCE WITH THESE INSTRUCTIONS.

B. Clearances

Always allow at least a 2-inch clearance between DuraChimney II Pipe and any combustible materials.

• Never ll any required clearance space with insulation or any other materials.

• Combustible materials include lumber, plywood, sheetrock, plaster and lath, furniture, curtains, electrical wiring, and building insulation.

C. Installation Notes

Proper planning for your DuraChimney II installation will result in greater safety, efciency, and convenience, as well as saving time and money. You must use only authorized DuraChimney II parts to maintain a listed chimney system. Do not mix parts or try to match with other products or use improvised solutions.

• Do not install damaged or modied parts.

• Practice good workmanship. Sloppy work could jeopardize your chimney’s safety.

• Keep electrical wiring and building insulation away from all chimneys.

• When deciding the location of your chimney, try to avoid modications to roof beams and other structural components of the building.

If you have any questions, contact either your dealer or Simpson Dura-Vent directly.

E. Cut Roof Opening

Determine and cut an opening in the roof directly above the opening below, and at least 4-inches larger than the chimney’s outside diameter to provide at least a 2-inch clearance all around the chimney.

• The chimney must be centered within this opening and maintain the minimum 2-inch clearance to combustibles.

F. Install Firestop

A restop is required on each oor penetration in multistory installation. Building Codes require a restop at every oor/ceiling level, including where the chimney penetrates into the attic. Figure 8.1 shows a typical 2-story installation with an attic.

Note: a restop is not installed where the chimney penetrates through the roof.

• The restop is installed on the underside of the ceiling/oor framing (Figure 8.2).

• Use a minimum of one 8 penny nail or one 1-1/4” wood screw per corner.

Framing

D. Frame Openings

• From the ceiling, drop a plumb bob to the center of the replace’s ue outlet and mark this center point on the ceiling.

• Mark appropriate cutting lines around the center point. Cut a square hole in the ceiling. Frame a level, square, 21 in. x 21 in. (533 mm x 533 mm) opening centered over the hole that you have cut.

• Frame openings at each oor level above the replace (Figure 8.1). These openings are to hold the restop and attic insulation shield.

• Locate each opening by dropping a plumb bob to the four corners of the opening below.

• Maintain the minimum 2-inch clearance/air space. Maintain the minimum clearances and dimensions as specied in Table 8.1.

Page 26

G. Assemble Chimney Sections

• Attach the rst chimney section or offset onto the top of the replace (Figure 8.3). Sheet metal screws are required to connect chimney section to the replace starter collar. Continue to add additional sections of chimney as needed.

• Use a wall strap every eight feet of chimney height.

• For each additional chimney section use four of the sheet metal screws provided to make a secure connection between the chimney sections (Figure 8.4). Do not penetrate the inner liner of the chimney.

H. 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! Rish of Fire! DO NOT use offset/returns greater than 30’. Chimney draft will be restricted and could cause overheating and re.

• Measure the shift required to avoid the overhead obstruction (Offset, Figure 8.5).

• Find the appropriate offset dimension listed in Table 8.2.

• The rise (see Figure 8.5) coinciding with the offset dimension measurement in Table 8.2 represents the required vertical clearance needed to complete the offset/ return.

I. Offset Elbow Installation

A 30° Elbow (measured from the vertical) is the largest that can be used in an offset. A 30° Elbow may not be combined with another Elbow to make a steeper offset (e.g. two 30° Elbows are not allowed to be put together to form a 60° elbow.). Avoid Elbows if possible. A totally vertical chimney is more efcient. When Elbows are necessary to avoid obstructions such as rafters, ridgepoles, or joists, you are only allowed to use 2 pair of Elbows in any one chimney system. Horizontal runs of chimney violate building code and are not allowed.

• Attach elbows Attach elbow to chimney section or other elbow by ating the

male and female ends with each other and using four sheet metal screws provided. Attach one elbow to the chimney section below, and align it for the offset. Determine the required offset length and attach an appropriate length (or lengths) of chimney section(s) above the elbow. Attach the second elbow above the chimney section to complete the offset (Figure 8.6).

• Secure offset Use an elbow strap to secure the offset. Secure the elbow

strap’s band to chimney around the upper portion of the top elbow, then tighten the nut and bolt until the clamp is rm. Wrap the elbow strap end over an adjacent joist or rafter and secure it with at least two 8-penny nails or two #8, 1-1/2” screws. Add additional elbow straps for each section of chimney in the offset (Figure 8.7). Every chimney section in the offset must be supported. Do not add more chimney sections until the elbows and offset are supported. Be sure that the chimney remains vertical.

Elbow Strap

J. Supplementary Support & Stabilizer

Install a supplementary support if total chimney height is greater than 50-feet, or if the replace manufacturer requires it. If additional support is needed, install one or more supplementary supports which can each support 25-feet of chimney (Fig. 8.8).

• Clamp the supplementary support band around the pipe using the nut and bolt provided, and anchor the support to nearby building framing.

• Always maintain the 2” clearance to combustibles from the chimney pipe. A stabilizer is available and may be required by some replace manufacturers to keep the chimney vertical and help maintain clearances to combustibles within a chase.

• Clamp the stabilizer to the pipe using the nut and bolt provided, and secure legs to nearby framing using plumber’s tape or guy-wires (Fig. 8.9).

Note: The stabilizer does not support the weight of the chimney, it is only used to keep chimney centered within a chase.

Install supplementary support if height exceeds 50 ft or if required by fireplace manufacturer

Each supplementary support holds up to 25 ft. of chimney

K. Install Attic Insulation Shield

The attic insulation shield must be installed where the chimney passes into an attic. Its purpose is to prevent debris and insulation from getting too close to the chimney. In attic areas where this shield cannot t, or is not used you must enclose the attic portion of the chimney in a framed enclosure. If the chimney is fully enclosed through the attic, an attic insulation shield is not required. Install the attic insulation shield as follows:

• Remove any insulation from attic oor around the framed opening.

• Assemble chimney sections until at least 18 inches of chimney extends above the restop.

• Slip the attic insulation shield over the chimney until the base sits squarely on the framed opening (Figure 8.10).

• Secure the attic insulation shield to the top of the framed opening using at least two 8-penny nails ort wo #8, 1-1/2 in. wood screws per side (Figure 8.11).

• Wrap the collar of the attic insulation shield around the chimney and fasten it loosely. Slide the collar down to meet the attic insulation shield. Tighten the bolts to secure the collar in place (Figure 8.11).

L. Install Roof Radiation Shields

Roof radiation shields must be used to provide protection for roof or chase framing members.

Note: Roof radiation shields do not allow for a reduced clearance to combustibles.

Clearance to combustibles must be a minimum of 2” away from the chimney pipe.

• Install roof radiation shields at either the top of the chase or where the chimney penetrates the roof, whichever is the top of the installation.

• Roof radiation shields are built with a 1/2” air gap standoff from the joist face (Figure 8.12). The corners of the roof radiation shields overlap each other to ensure proper position.

• Secure the roof radiation shields to the top of the framing members using screws or nails in the corners.

• If framing members are further away from the chimney than 2 in., center the roof radiation shield to the chimney on the framing member and secure in place with screws or nails.

M. Attach Flashing

For chase enclosures, use the Chase Top Flashing. The Chase Top Flashing allows for a 1-1/2 in. clearance maintained from the chimney (Figure 8.14) and provides required ventilation air.

• Chase Top Flashings (includes Chase Top Collars and Spacing Clips) are available from your HHT dealer.

• Additional non-combustible structural supports can be eld-fabricated to help support the Chase Top Flashing if needed, provided the air ventilation requirements are maintained. See Figure 8.15.

• If the ChaseTop Flashing (40 in. x 40 in.) does not ensure the minimum 1/2 in. spacing and perimeter ventilation requirements as shown in Figure 8.13., use a Chase Top Collar and eld-construct the ashing as needed for the chase dimensions. Skip to Field-Constructed Chase Top Flashing.

Heatilator • Birmingham BIR50-B • 4059-682C • 8/12

Page 29

• Install the Chase Top Flashing at the top of the chase with a 1/2 in. minimum air clearance off the top of the chase construction (Figure 8.13).

• Spacing clips can be eld-fabricated as needed out of 24 GA sheet metal or other suitable non-combustible material (refer to Figure 8.13)

• Insect-guard screening may be added between the chase and Chase Top Flashing.

• Secure the Chase Top Flashing to the chase with at least three screws or nails per side.

• When installed, the bottom of the chimney cap must be at least 6 in. above the Chase Top Flashing.

• Secure the chase top ashing to the chase with at least three screws or nails per side.

• When installed, the bottom of the chimney cap must be at least 6 in. above the ashing (Figure 8.16).

N. Finish Top

• Slide the storm collar down over the chimney to the top of the ashing. The storm collar must be installed 1 in. off the chase top ashing to provide proper ventilation (Figure

8.17).

• Tighten the bolts of the storm collar and seal the storm collar against the chimney with sealant. Be sure chimney and offsets are properly supported.

• Apply a non-hardening waterproof sealant around the chimney at the point where the storm collar will meet the chimney just above the ashing (Figure 8.17).

• Attach the chimney cap onto the top of the chimney by setting the female end of the cap onto the male end of the last chimney section. Secure the cap by using four sheet metal screws (provided, Figure 8.18.)

• Do not push down from the top portion of the cap as this may damage the cap. Push from the lower section of the cap if needed.

• The chimney cap top can be removed for chimney cleaning as described in the Chimney Inspection & Cleaning section (Section 3) of this manual.

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.

Figure 9.1 Chase Assembly

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 re

stop 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.

Shrouds

A. Shroud Requirements

WARNING! Risk of Fire! Shrouds must be constructed as specied. Improper construction may overheat chase top.

• Chase top shrouds may be field constructed where permitted by regional building codes.

NOTICE: Some regional codes require an agency-Listed

shroud. Consult your local building ofcials.

• Hearth & Home Technologies Inc. supplies UL listed shrouds. See your dealer for details.

Shrouds can either be eld-fabricated or factory-fabricated, but they must meet the requirements as specied in these instructions. Shrouds must be constructed of a minimum 24 ga (.024 in.) stainless steel, aluminized steel, galvanized steel, or copper. Other materials may also be used, such as brick, mortar, stucco, stone, etc. provided they are completely non-combustible. Check with your local building code authroities for any additional shroud requirements. Shrouds must be able to be removed to allow chimney access to properly clean the chimney. DuraChimney II installations which include the use of a shroud must comply with the following requirements (Figure 10.1)

• DuraChimney II must maintain at least 2 in. (51 mm) clearance from combustible materials.

• The chase enclosure must be ventilated.

• The chase top ashing or eld-fabricated chase pan must be used. Field-fabricated chase pans are acceptable if they meet these requirements:

- Material must be 24 ga (.024 in) galvanized steel or

equivalent.

- Chase pan must have opening 3 in. (76 mm) larger

than outside diameter of chimney pipe with at least a 1/2 in. (13 mm) upturned ange/collar.

- Chase pan must overhang chase by 1/2 in. (13 mm)

per side for proper air ow.

- Chase pan must have a 1 in. (25 mm) down turned

outside edge (weather protection).

14 in. (345 mm) diameter chimney must extend at least 6 in. (152 mm) above chase top flashing.
