SAFETY INSTRUCTIONS

Safety Notice: If this stove is not properly installed, a house/building fire may result. For your safety, contact local building or fire officials about permits, restrictions, and installation requirements for your area.

Read All Instructions carefully.

  1. The installation of this stove must comply with your local building code rulings. Please observe the clearances to combustibles (see figure 3, figure 4 & figure 5).
  2. Verify that the stove is properly installed before firing the stove for the first time. After reading these instructions, if you have any doubt about your ability to complete your installation properly, you must obtain the services of a professional licensed installer familiar with all aspects of safe and correct installation. DO NOT use temporary or makeshift compromises during installation.
  3. DO NOT store wood, flammable liquids or other combustible materials too close to the unit. Refer to certification label on back of unit (see figure 3, figure 4 & figure 5).
  4. Do not install this stove in a mobile home, manufactured home, trailer or tent (NO EXCEPTIONS! per HUD Federal Standard: 24 CFR Ch.XX).
  5. If any parts are missing or defective, please notify the dealer or manufacturer immediately. DO NOT OPERATE A STOVE THAT IS MISSING ANY PARTS!.
  6. Do not tamper with combustion air control beyond normal adjustment capacities.
  7. Always connect this stove to a chimney and vent to the outside. Never vent to another room or inside a building. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.
  8. DO NOT CONNECT a wood burning stove to an aluminum Type B gas vent. This is not safe. Use approved masonry or a UL 103 HT Listed Residential Type and Building Heating Appliance Chimney. Use a 6” diameter chimney or larger, that is high enough to give a good draft. (see specifics in chimney installation instructions.)
  9. Be sure that your chimney is safely constructed and in good repair. Have the chimney inspected by the fire department or a qualified inspector. Your insurance company should be able to recommend a qualified inspector.
  10. Creosote or soot may build up in the chimney connector and chimney and cause a house/building fire. Inspect the chimney connector and chimney twice monthly during the heating season and clean if necessary (see Maintenance & Service Hints).
  11. In the event of a chimney fire, turn the air control to closed position, leave the building and CALL THE FIRE DEPARTMENT IMMEDIATELY! Have a clearly understood plan on how to handle a chimney fire by contacting your local or provincial fire authority for information on proper procedures in the event of a chimney fire.
  12. To prevent injury, do not allow anyone to use this stove who is unfamiliar with the correct operation of the stove.
  13. Do not operate stove while under the influence of drugs or alcohol.
  14. Ashes should not be allowed to accumulate higher than the ash pan. Dispose of ashes in a metal container with a tight fitting lid. Keep the closed container on a noncombustible floor or on the ground, well away from all combustible materials. Keep the ashes in the closed container until all cinders have thoroughly cooled. The ashes may be buried in the ground or picked up by a refuse collector.
  15. The paint used on your stove may give off smoke and/or odor during the first fires. This may occur during the first 12 to 15 fires until the paint has cured. After the paint has cured this will end and not reoccur. Persons with lung conditions or owners of susceptible domestic pets (such as birds) should take prudent precautions. Open windows and doors as needed to clear smoke and odor. If the stove is overfired, paint discoloration will occur.
  16. This stove has a painted surface which is durable but it will not stand rough handling or abuse. When installing your stove, use care in handling. Clean with soap and warm water when stove is NOT hot. Do not use any acids or scouring soap, as these solvents wear and dull the finish.
  17. While stove is in operation, all persons, especially young children should be alerted to the hazards from high surface temperatures. Keep away from a hot stove to avoid burns or clothing ignition.
  18. If small children will be in the same room as the stove during operation, provide a sturdy barrier to keep them at a safe distance from the stove. NEVER LEAVE SMALL CHILDREN UNSUPERVISED when they are in the same room as the stove.
  19. Keep stove area clear and free from all combustible materials, gasoline, and other flammable vapors and liquids.
  20. To prevent burns, always wear protective clothing, leather hearth gloves and eye protection, while tending the fire.
  21. While in operation, keep the feed door closed at all times except while tending the fire.
  22. Do not overfire the stove. Overfiring will occur if the feed door or ash clean-out cover are left open during operation. Such actions will result in very dangerous operating conditions.
  23. All power cords and electrical appliances and/or assemblies must be kept outside of the clearance dimensions shown in this manual for combustible materials.
  24. DO NOT ELEVATE FIRE! Build fire directly on the bottom of the firebox. This stove has not been tested with the use of grates, andirons, or other means of elevating fire and should not be used.
  25. For further information on using your stove safely, obtain a copy of the National Fire Protection Association (NFPA) publication, "Using Coal and Wood Stoves Safely" NFPA No. HS-10-1978. The address of the NFPA is:

  1. Drill two 1/4" holes centered on either side of the pipe section 6" from the top end of the pipe (see figure 6).
  2. Remove the handle from the damper then slide the damper into the pipe.
  3. Align the damper with the holes drilled in step 1 and insert the handle through the holes and the damper.

NOTE: This damper is necessary for the proper operation of the stove and to meet EPA emissions requirements for heating appliances.

DRAFT DAMPER MUST be installed before use. 
(NO EXCEPTIONS)


Pipe Installation

  1. The crimped end of the stovepipe fits inside the stove collar. Install additional pipe and elbow with the crimped end towards the stove. This will allow any condensation in the flue to run back into the firebox.
  2. Horizontal pipe runs must slope upwards towards the chimney at least 1/4" per foot of horizontal run.
  3. You must have at least 18 inches of clearance between any horizontal piping and the ceiling.
  4. The pipe cannot extend into the chimney flue (figure 7).
  5. Secure pipe/elbow sections with three (3) sheet metal screws at each joint to make the piping rigid.
  6. It is recommended that no more than two (2) 90° bends be used in the stovepipe installation. The use of more than two 90° bends may decrease the amount of draw and possibly cause smoke spillage. Where possible, use only corrugated (nonadjustable) elbows. These provide a better seal.
  1. The chimney connector must not pass through an attic or roof space, closet, or any concealed space, or floor, ceiling, wall or combustible construction. (See chimney connector systems and clearances.) A UL 103 HT Listed chimney must be used from the first penetration of ceiling or wall to the chimney cap. Never use single wall connector pipe as a chimney - a house fire could result.
NOTE: Stove pipe is NOT INCLUDED.
To purchase pipe, visit your local hardware, home or building center. See Locating Stove for additional specifications.

Stove / Flue Installation


 

Chimney Connections

The stove must be connected to either a masonry or manufactured chimney built and tested to the specifications listed on the previous pages. Chimneys perform two functions:  

  1. As a means of exhausting smoke and flue gases which are the result of fuel combustion. 
  2. The chimney provides "draft" which allows oxygen to be continuously introduced into the appliance, so that proper combustion is possible.

Fig. 8   Masonry Chimney Connection
Masonry Chimney Connection

NOTICE: Always provide a source of fresh air into the room where the stove is located. Failure to do so may result in air starvation of other fuel burning appliances and the possible development of hazardous conditions, fire or death.

Your stove itself does not create draft. Draft is provided by the chimney. To achieve proper draft your chimney must meet the three minimum height requirements (see figure 9, figure 10, figure 11). A minimum of 0.05 w.c. (measured in water column) is required for proper drafting to prevent back puffing, smoke spillage, and to maximize performance. (Gauges to measure draft are readily available at stove stores and are economical to rent or purchase.) Factors such as wind, barometric pressure, trees, terrain and chimney temperature can have an adverse effect on the draft. The manufacturer cannot be held responsible for external factors leading to less than optimal drafting. Should you have a problem with inadequate draft, you should contact a licensed heating and cooling contractor for assistance in solving the problem.

IMPORTANT Installation Points

  1. Size the chimney flue to the stove pipe. This stove requires a 6" chimney flue.

  2. Never connect this unit to a chimney serving another appliance.

  3. The chimney must meet all minimum height requirements.

  4. Never use a chimney to ventilate a cellar or basement.

  5. Contact your local building authority for approved methods of installation and any necessary permits and/or inspections.

Masonry Chimney

Before using an existing masonry chimney, clean the chimney, inspect the flue liner and make any repairs needed to be sure it is safe to use. Make repairs before attaching the stove. The connector stove pipe and fittings you will need to connect directly to a masonry chimney are shown in figure 8.

If the connector stove pipe must go through a combustible wall before entering the masonry chimney, consult a qualified mason or chimney dealer. The installation must conform to local building and fire codes and latest edition of NFPA 211.

If there is a cleanout opening in the base of the chimney, close it tightly.

Manufactured Chimney

REFER TO CHIMNEY AND CHIMNEY CONNECTOR MAKER’S INSTRUCTIONS FOR INSTALLATION AND USE.

Chimney Construction Through Attic Space:

Chimney Construction Through Attic Space

Use only 6” diameter listed chimney UL 103 HT. Chimney made to this listing is High Temperature rated to 2100 degrees Fahrenheit. Use chimney from only one manufacturer. Never mix brands. Carefully follow the chimney manufacturer’s stated requirements and clearances. Use the chimney manufacturer’s attic guards, roof supports, flashing and fire stops when passing through a ceiling. Use a listed thimble when passing through a combustible wall. Do not use makeshift compromises during installation. Never use a single-wall connection pipe as a chimney!

When using a pre-existing chimney, have it’s condition and installation inspected before using. Make sure that the chimney meets all of the UL rating requirements listed above. Be aware that not all manufactured chimney is of the UL 103 HT type.

NOTE: It is recommended that you contact a licensed heating and cooling contractor (consult your local yellow pages) for chimney installation.

Manufactured chimney with the proper required UL listing is available from most home centers, hardware stores, and HVAC supply stores.

Venting to Existing Fireplace

In some instances, people desire to convert an existing fireplace for stove use. Usually, safe connection to an existing masonry chimney requires more work than using a prefabricated chimney. The existing fireplace must be closed and sealed at the damper with high-temperature caulk, ceramic wool, or furnace cement. Prior to installation, clean and inspect the existing flue and smoke shelf. Installation should be designed so the system can be dismantled for periodic cleaning and inspection. Before conversion, make sure the existing chimney is structurally sound, the chimney incorporates a flue liner and make sure it is in good condition. (A flue liner consists of clay tile that protects the brickwork of a chimney. If a chimney does not have a liner, or it is damaged, have it relined by a professional. 
Do Not use a chimney that is unlined or damaged!

If you have any question regarding the condition of the chimney, consult a qualified licensed contractor, qualified engineer, competent mason, certified Chimney Sweep, or a knowledgeable inspector. Consult your insurance company if you cannot find a qualified expert.
 

CAUTION: Not all fireplaces are suitable for conversion to a wood stove. Check with a qualified expert.

Many prefabricated fireplaces are of the "zero-clearance fireplace" category. These consist of multi-layered metal construction. They are designed with enough insulation and/or air cooling on the base, back and sides so they can be safely installed in direct contact with combustible floors and walls. 

Although many prefabricated fireplaces carry endorsements from nationally recognized organizations for use as fireplaces, they have not been tested for connection to wood stove heaters. Connecting a stove to such a device will void the manufacturer's warranty.

Steel-lined fireplaces are constructed with 1/4" firebox liner, an air chamber in connection with 8" of masonry. These can be safely used with wood burning stoves. They contain all the essential components of a fireplace, firebox, damper, throat, smoke shelf, and smoke chamber. Many look identical to masonry fireplaces and should be checked carefully before connecting a stove to them.

Venting a stove directly into a fireplace does not meet code and should not be attempted. (This constitutes connection to another appliance - the fireplace.) Combustion products will be deposited and build up in the firebox or fireplace. The stove warranty will be void with such an installation. Do not create a hazard in your home by connecting in this manner.

Fireplace Installation

Directly connecting the stovepipe into the existing masonry chimney (see figure 12 "Type A" fireplace conversion) of the fireplace is the only approved method of installation. This is a complicated and involved process and to insure safety should only by done by a qualified installer.

  1. An entry hole must be cut through the masonry and tile liner with minimal damage to the liner. At least 8" of liner must remain below the entry position. When locating the stove and stovepipe, all minimum clearances must be observed from combustible surfaces including mantels, combustible trimwork, ceilings and walls. Positioning the center of the stove pipe entry into the chimney 24" below the ceiling should insure proper clearance for a 6" stovepipe. 

  2. Install a metal or fire clay (5/8" minimum thickness) thimble. Make sure the thimble is flush with the inner surface of the chimney liner and does not protrude into the flue (see figure 7).

  3. Secure the thimble with refractory mortar. The thimble should be surrounded by 8" of solid unit masonry brickwork or 24" of stone.

  4. Install the stovepipe into the thimble as far as possible without extending past the flue lining (see figure 7 & figure 8).

  5. A small airspace (about 1/2") should remain between the stovepipe and thimble to allow for expansion of the pipe. Seal this airspace with high-temperature caulking or ceramic wool.

  6. Secure and seal the damper in the closed position using high-temp caulking, ceramic wool, or furnace cement. Also check to see if the chimney has a cleanout. If it does, make sure it is closed and sealed as well. A leaky cleanout will greatly reduce draft efficiency.

Operating Instructions

CAUTION: HOUSE FIRE HAZARDS

  • Do not store wood on floor protector, underneath stovepipe or anywhere within minimum clearances from combustible surfaces specified for this stove. (36")

  • Overfiring may cause a house fire. You are overfiring if the stove or chimney connector glows red.

  • Build fires only on integral grate included with the stove.


WARNING: EXPLOSION HAZARD

  • Never use chemicals, gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar flammable liquids to start or "freshen-up" a fire in the stove.

  • Keep all flammable liquids, especially gasoline, out of the vicinity of the stove, whether in use or in storage.


OPERATING SAFETY PRECAUTIONS

1.   Never overfire this stove by building excessively hot fires as a house/building fire may result. You are overfiring the stove If stove or stovepipe begins to glow or turn red.

2.   Never build extremely large fires in this type of stove as damage to the stove or smoke leakage may result.

3.   Unit is HOT while in operation. Keep children, clothing, and Furniture away from hot stove. Contact may cause skin burns. Do not touch the stove after firing until it has cooled.

4.   Provide air into the room for proper combustion.

5.   Inspect stovepipe every 60 days.
Replace immediately if stovepipe is rusting or leaking smoke into the room.

This stove is designed to burn
WOOD FUEL ONLY.

Hardwood, 20" to 24" should be split and air dried (seasoned), for 6 months to obtain maximum burning efficiency. Wood should be stored in a dry, well ventilated area.
 

NOTICE: Use solid wood materials only. Do Not burn garbage or flammable fluids. Do Not use Coal as coal or charcoal will destroy the grates and / or firebox. 

NOTE: Spin draft is factory set to meet EPA regulations and is not adjustable. Draft induction is controlled by thermostat setting (See Thermostat).

Lighting

  1. Set the thermostat on "HIGH" and open draft damper to provide maximum draft.
  2. Using the separable handle, open the feed door and place paper and kindling on the grate for starting the fire.
  3. Light fire, close feed door and secure tightly.
  4. Add fuel after fire is burning briskly. Use care not to smother the kindling fire when adding wood. 
  5. Set the thermostat to maintain desired temperature. "MEDIUM" setting is normally satisfactory. Set higher or lower for your personal comfort level. 

Adding Fuel

When possible, add small amounts of fuel each hour or so instead of piling large quantities of fuel every 4 or 5 hours. This will give a more complete combustion process and less buildup of tars, soot, or creosote will occur in the chimney.

  1. Set thermostat to "HIGH" and open pipe draft damper before opening the feed door.
  2. Empty the ash pan regularly. Do not allow ashes to pile up higher than the sides of the ash pan. If ashes build up to the grate, it can warp and burnout will occur. If allowed to overfill, ashes may spill when removing the pan.
  3. Properly dispose of hot ashes (see Safety Instructions, item #10.)

Minimum Fire

The rate of burning at the "LOW" thermostat setting can be further controlled by adjusting the flue draft damper.

  1. Fully close the thermostat and draft damper to make the fuel burn longer.

  2. To increase rate of burn, turn up the thermostat or open the draft damper. This will help reduce the formation of creosote or soot (see Chimney Maintenance).


Thermostat

The thermostat controls the rate of burn by opening or closing a draft damper on the lower front of the firebox. The thermostat control was calibrated at the factory and is not adjustable. The thermostat is mounted behind the front control panel and the damper is mounted to the lower front of the firebox. The cabinet lid may be opened (when stove has cooled) for access to these components.

CAUTION: DO NOT OPEN OR CLOSE TOP WHEN HEATER IS HOT!
  1. To open, when stove has cooled, grasp the cabinet top at front (see figure 13) and lift all the way up.
  2. Gently lower the top until the top support rod latches to hold the top in the "up" position (see figure 13).
  3. To close, lift the top until the support rod is unlatched.
  4. Pull the support rod forward as you lower the cabinet top.

If the room temperature is not satisfactory, check the following items:

To decrease the amount of heat at "LOW" setting:

  1. Check feed and ash doors to be sure that they are closed and secured tightly.
  2. Check the connector pipe to see that it is sealed in the flue collar and at all joints.
  3. Make sure the flue draft damper is fully closed.

Maintenance & Service Hints

DRAFT: Draft is a function of the chimney, not the stove — do not expect the stove to draw. Smoke spillage into the house or excessive buildup of condensation or creosote in the chimney are warnings that the chimney is NOT functioning properly. Correct the problem before using the stove. Following are some possible causes for improper draft.

  1. The connector stovepipe may be pushed into the chimney too far, stopping the draft.

  2. If the chimney temperature is too cool, water will condense in the chimney and run back into the stove. Creosote formation will be rapid and may block the chimney. Operate the stove at a fire level high enough to keep the chimney warm to prevent condensation from forming.

  3. If the fire burns well but sometimes creates excess smoke or burns slowly, it may be caused by the chimney top being lower than another part of the house or a nearby tree. The wind blowing over a house or tree, falls on top of the chimney like water over a dam, beating down the smoke. The top of the chimney should be at least three (3) feet above the roof and be at least two (2) feet higher than any point of the roof within ten (10) feet. (See figure 9, figure 10, figure 11.)

NOTE: A draft reading of 0.05 to 0.06 W. C. (Water Column) is suggested for proper burning of this stove.

Chimney Maintenance

CREOSOTE -  Formation and Removal:  When wood is burned slowly, it produces tar and other organic vapors which combine with expelled moisture to form creosote. Creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. If ignited, this creosote creates an extremely hot fire which may ignite surrounding materials resulting in a building fire.

The chimney connector and chimney should be inspected at least twice a month during the heating season to determine if a creosote buildup has occurred.

If creosote has accumulated, it should be removed. Failure to remove creosote may result in ignition and may cause a house/building fire. Creosote may be removed using a chimney brush or other commonly available materials from your local hardware retailer.

Chimney fires burn very hot. If the unit chimney connector should glow red, reduce the fire by closing the inlet air control and immediately call the fire department.
 

CAUTION: A chimney fire may cause ignition of wall studs or rafters which were assumed to be a safe distance from the chimney. If a chimney fire has occurred, have your chimney inspected by a qualified expert before using again.

A fire in the firebox may be smothered by pouring a large quantity of coarse salt, baking soda, or cool ashes on top of the fire.

Floor Protector Material Calculations

This stove has been tested for and must be installed on a floor protector with the proper Thermal Resistance or R-value as stated in the installation instructions for Locating Stove, step 1, of this manual. If the floor protector materials listed in the instructions are not available, materials with an equivalent R-value may be substituted.

Alternate materials may be rated with C-factor (Thermal Conductance) or k-factor (Thermal Conductivity) ratings which must be converted to R-value to determine if the alternate material meets the tested requirements. The following instructions provide the proper information and formulas for conversion to R-value.

To determine if alternate materials are acceptable follow this sequence.

  1. Convert material specifications to R-value:
    1. R-value given — no conversion necessary
    2. k-factor is given with a required thickness (T) in inches:   R = 1/k x T
    3. C-factor is given: R = 1/C
  2. Determine the R-value of proposed alternate floor protector:
    1. Use formulas in step 1 above to calculate R-value of proposed material(s).
    2. For multiple layers, add R-values of each layer to determine overall R-value.
  3. If the overall R-value of the floor protector system is equal to or greater than the floor protector specifications given, the alternate is acceptable.

Definitions:

Thermal conductance(C)  =       BTU    
(hr)(ft2)(°F)
=     W    
(m2)(°K)
   
Thermal conductivity (k)  = (Btu)(inch)
(hr)(ft2)(°F)
=     W    
(m)(°K)
=     Btu    
(hr)(ft)(°F)
Thermal resistance (R)  = (ft2)(hr)(°F)
Btu
= (m2)(°K)
W
   

Example:

The specs of floor protector material should be 3/4-inch thick material with a k-factor of 0.84.
The proposed alternative material is 4" brick with a C-factor of 1.25 over 1/8-inch mineral board
with a k-factor of 0.29.

Step 1: Convert specs to R-value.

R = 1/k x T = 1/0.84 x 0.75 = 0.893 System must have a R-value of 0.893 = Rspecs

Step 2: Calculate R-value of individual components

4" Brick with C-factor = 1.25. R = 1/C = 1/1.25 = 0.80 = Rbrick
1/8-inch (0.125") mineral board with k-factor = 0.29. R = 1/0.29 x 0.125 = 0.431 = Rmin.brd.

Step 3: Add R-values of components to get total R-value of system

Rbrick + Rmin.brd = 0.80 + 0.431 = 1.231 = Rsystem

Step 4: Compare Rsystem to Rspecs

Rsystem = 1.231 is larger than Rspecs of 0.893. System R-value exceeds the required specifications and therefore is an acceptable alternative.
