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 masonryorfactorybuilt.Ifitisamanufacturedchimney, 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 cross-sectional area of 42 to 49 inches. This is adequate for a 6 inch stove connector, which matches the appliance flue collar.

Important! Theconnectorpipemustbeconstructed 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 ground-level 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)Improperchimneyheight-Chimneydoesnotextend 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)Treesorothertopographicalbarriers-Treesthatare 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.

Venting & Grates

E)Improperly sized flue - Too small of a chimney is incapable of moving the volume of air necessary. Too large of a flue could have trouble warming up to create the necessary upward flow.

F)Chimney offsets - Offset chimneys should be avoided if possible. Not only can the offset affect draft, it is also a place for debris to collect over time.

G)Too many elbows - The flue connector has more than two elbows in it. Sometimes, depending on overall chimney performance, one elbow could be too many.

H)Vent sharing - No more than one heating appliance shall vent into a single flue.

THE MOST IMPORTANT THING TO REMEMBER ABOUT CHIMNEYS IS THEIR NEED FOR MAINTENANCE AND CLEANING. IF A CHIMNEY IS NOT CLEANED ON A FREQUENT BASIS, IT WILL AFFECT DRAFT,AS WELLAS BEACONTRIBUTING FACTOR TO A POTENTIAL CHIMNEY FIRE.

3.3 what to do if you have a problem. If you have a chimney fire:

1.Be sure everyone is out of the house.

2.Call the fire department.

3.Close the draft control on the ash door and make sure both doors on the stove are closed and latched.

4.Do not put water on the fire, this will cause unnecessary damage to the stove and flue.

5.Have the chimney inspected and repaired prior to building another fire.

Smoke puffs out of stove;

A)Check previous suggestions for insufficient draft.

B)Check draft control for proper operation.

C)Chimney may be too low. Increase height.

D)Add more fresh air to the room. Your home may be so tight that there is not enough oxygen getting to the fire.

E)Remember, open the draft control and crack the door open slightly before reloading or checking the fire.

F)Check the ashes. The ash pan and firebox may be overloaded with ashes.

G)Check the chimney cleanout door to ensure it closes properly.

4. Grates

4.1 GRATE SYSTEM AND CONTROLS.

The Grates are made of heavy-duty cast iron. The function of the grate system is to support the coal while allowing air flow through the fire. The grate system also allows removal of the ashes by shaking them through the grates.

The grates are removable without the use of tools, once the fire bricks are removed, the grates simply lift out. Lift the right end higher to disengage from the shaking link. To re-install the grates, lower them, one at a time, left end first, be sure the grate hooks into the grate link as you drop it into place.

Your grates will last forever, as long as you keep your ashes cleaned out of the stove. When ashes are left pile-up against the grates, the air-flow is blocked. With no air flow through the grates, they will begin to sag from the intense heat.

The grates are designed to accommodate three different sizes of anthracite coal. Pea is defined as being able to fit through a round screen hole of 9/16” to 7/8”. Nut or Chestnut is defined as being able to fit through a round screen hole of 7/8” to 1½”. Finally, Stove coal which is 1½” to 2½” in size. Pea or Nut you’ll find work the best for starting a fire, while all three sizes burn just as well.

The external shaker handle allows for greater safety from burns, and the convenience of needing no extra tools.
