This stove consumes air when it is burning.

If your house is especially tight, It is advisable that a Floor Protector nearby window be opened slightly while burning the

stove.

Information in this manual is manufacturer’s recommendations. If there is a discrepancy between these recommendations and your local code requirements, you must follow local codes.

1.3 CURING PAINT.

During the first few hours of burning, a blue smoke will be observed rising from the painted surfaces of the stove. This is the paint being cured, and will disappear over time. Increase the amount of fresh air in the room during this initial break-in period. This may be achieved by opening doors or windows.

1.4 Mobile Homes.

This stove is not approved for use in mobile /manufactured homes.

Installation

2.3 Assembly.

Slide the blower into the slotted bracket on the rear of the stove. The blower will rest at the bottom of the slot.

The shaker handle bolts onto the shaker block using the bolts and lock washers provided.

The draft control is bolted through the hole in the center of the ash door as shown below. The knob should spin freely and open to a distance of about 1/4 inch from the door surface, while being able to close against the face of the door.

The viewing glass is installed between the door and the window frame. The glass gasket is installed only on the sides of the glass panel. The top and bottom of the glass are open to provide air-wash and secondary air to the firebox. The glass frame is secured to the door with four bolts.

The Mark II and Mark III also have a top trim piece which bolts onto the top of the door.

Be sure the frame bolts and trim bolts are secured.

2.4 GENERAL INFORMATION.

Installation Checklist:

A.Have your stove installed by a trained installer. Preferably one who is certified by the National Fireplace Institute or similar certification agency.

B.Before starting Installation, check for proper clearance to combustibles where the stove is going to be located.

C.Never vent a solid fuel burning appliance into a flue serving another appliance.

D.Have the chimney inspected and thoroughly cleaned. Inspect that it is a Class “A” chimney either masonry or factory built. If it is a manufactured chimney, ensure that it is installed as per the manufacturers requirements. Be sure that the chimney is tall enough. Solid fuel chimneys fall under a general rule, 16 ft. minimum height, 2 ft. taller than anything within 10 ft., and 3 ft. above where it passes through the roof line. The chimney must be capable of a minimum

.06 inches of water column of draft when the stove is burning.

E. Limit the amount of connector pipe. Position the stove as close to the flue as possible. (8 ft. or less) No more than two 90° elbow fittings should be used.

Any horizontal connector pipe should have at least 1/4 in. of rise per foot in length. A barometric damper may be installed to prevent excessive or erratic draft.

MANUAL DAMPERS OR “HEAT SAVERS” MUST NEVER BE INSTALLED IN THE FLUE PIPE. IMPROPER OPERATION COULD RESULT IN DEATH.

Venting

Where an existing chimney is used, it must be large enough to provide a draft adequate for removing the gaseous products of combustion. The cross-sectional area of the chimney must be at least 25 percent greater than that of the connector. As a general rule, common 8” X 8” flue liner has an actual interior crosssectional area of 42 to 49 inches. This is adequate for a 6 inch stove connector, which matches the appliance flue collar.

Important! The connector pipe must be constructed of 24 gauge material or thicker.

3. Venting & Chimneys:

3.1 TYPES OF CHIMNEYS

The chimney is one of the most important, yet the most neglected and misunderstood portion of any solid fuel burning appliance installation. Do not connect your stove to a chimney flue that already serves another heating device.

The stove must be connected to its own flue. A minimum 8” X 8” is necessary for proper operation.

Under no circumstances should a manual flue damper be installed in the smoke pipe between the stove and the chimney.

Caution! the chimney must be a “class A” chimney in good working condition. the use of aluminum “type b” gas vent for solid fuels is not only un-safe but it is prohibited by the national fire protection agency (nfpa) code.

There are three types of “Class A” chimneys;

1)Masonry with a tile liner, including brick, block, stone, etc. It must be supported by a groundlevel foundation.

2)Insulated “Class A” manufactured chimney, listed and certified by a national test agency.

3)Triple-walled metal “Class A” chimney, listed and certified by a national test agency.

If your masonry chimney has not been used for some time, have it inspected by a qualified person (building inspector, fire department personnel, etc.). If a listed and certified manufactured chimney is to be used, make certain it is installed in accordance with the manufacturers instructions and all local codes.

A coal stove can perform only as well as its venting system will allow it to.

3.2 common chimney problems

In order to have a properly operating heating system, the chimney needs to be capable of providing sufficient draft. The minimum required draft is .06 inches of water column (WC). To measure the draft, drill a hole in the connector pipe and attach a draft meter. First, check the draft above the barometric damper (if installed). Then check it below the barometric damper and make your damper adjustment to where it opens to prevent the draft from going higher than the .06

in WC. If the chimney is incapable of supplying the necessary draft, it will need to be improved. Whether it needs to be raised to a taller height, a flue liner installed, or a different style of cap placed on the top, the improvement method will need to be determined.

Reasons for insufficient draft;

A)Leaking chimneyAir leaking in around a loose fitting cleanout door, joints or seams in connector pipe are not secured properly, cracks or other defects in masonry.

B)Improper chimney height - Chimney does not extend to a sufficient height above the roof line. (Remember the 3 ft.-2 ft.-10 ft. rule)

C)Obstructions in the chimney - Make sure the chimney has been cleaned. Different animals have been known to build nests in chimneys.

D)Trees or other topographical barriers - Trees that are taller than the house can cause the air currents to flow downward over the peak of the roof. This would lead to a down draft effect on the chimney. This can also be caused by adjacent buildings or fixtures. It could even be from a different peak on the same structure.
