SUPERIOR WCT2042WSI (01) PDF Document

To ensure safe operation of the SUPERIOR WCT2042WSI, follow these safety precautions:

1. Do not store or use gasoline or any other flammable vapors or liquids in the vicinity of this or any other appliance.

2. Due to high temperatures, the appliance should be located out of traffic and away from furniture and draperies.

3. Do not place clothing or other flammable materials on or near the appliance.

4. Never leave children unattended when a fire is burning in the fireplace.

5. Use only solid wood or processed solid fuel fire logs. Do not poke or stir logs while they are burning.

6. Use for supplemental heat only; this fireplace is not intended to be used as a substitute for a furnace to heat an entire home.

7. Do not install a fireplace insert in this fireplace unless the manufacturer’s instructions with the insert specifically state that it has been tested for use with this fireplace.

The following minimum clearances must be maintained for the SUPERIOR WCT2042WSI:

Back and sides of fireplace: 3/4 inch (19 mm) minimum (not required at nailing flanges).

Floor: 0 inches (0 mm) minimum.

Perpendicular wall to opening: 12 inches (305 mm) minimum.

Top spacers: 0 inches (0 mm) minimum.

Chimney outer pipe surface: 1 inch (26 mm) minimum.

Mantel clearances: Woodwork such as trims or mantels must not be placed within 12 inches of the fireplace opening and within 9 inches of the top louver opening.

The damper handle, which opens and closes the damper blade, is located inside the firebox at the center toward the back wall. Follow these steps for operation:

To Open: Pushing the handle back into the keyway slot will free the damper blade to automatically open. The vent damper must be locked in the full open position before operating the fireplace.

To Close: Push the handle back into the keyhole slot, then pull down and forward to lock it in place.

The SUPERIOR WCT2042WSI is approved for the following fuel types:

1. Solid Wood: Use only dry and well-seasoned hardwood for the best performance.

2. Vented Gas Logs: Approved to ANSI Z21.60 or Z21.84 standards.

3. Vent-Free Gas Log Heaters: Approved to ANSI Z21.11.2 standard. Note that an IHP hood must be installed when using a vent-free log heater.

4. Processed Solid Fuel Fire Logs: Use only those evaluated for application in a fireplace and follow all manufacturer warnings on the packaging.

Do not burn the following materials in the SUPERIOR WCT2042WSI:

Garbage, lawn clippings, or yard waste.

Materials containing rubber, including tires, or materials containing plastic.

Waste petroleum products, paints, paint thinners, or asphalt products.

Materials containing asbestos.

Construction or demolition debris.

Railroad ties or pressure-treated wood; woods dipped in tar, pitch, creosote, etc.

Manure or animal remains.

Salt water driftwood or other previously salt water saturated materials.

Unseasoned wood or Christmas tree branches.

Paper products, colored paper, cardboard, plywood, or particleboard.

Gasoline, naphtha, engine oil, flammable liquids, solvents, grease, charcoal, or coal.

Ashes should be placed in a metal container with a tight-fitting lid. The closed container of ashes should be placed on a noncombustible floor or on the ground, well away from all combustible materials, pending final 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.

To install a gas line, follow these steps:

1. Remove the knockout indentation on the refractory or firebrick wall located above the refractory hearth floor. Firmly tap it with a solid object, such as a 1/2 inch dowel, until it is released. Remove fragmented portions of refractory.

2. Remove the gas line cover plate located on either side of the fireplace and pull out the insulation from the gas line conduit sleeve. Save the insulation for reuse.

3. Run a 1/2 inch black iron gas line into the fireplace through the rear at the gas line conduit sleeve. Provide sufficient gas line into the fireplace chamber for fitting connection.

4. Secure the incoming gas line to wood framing to provide rigidity for the threaded end.

5. Repack insulation around the gas line and into the sleeve opening. Seal any gaps between the gas line and the refractory knockout hole with refractory cement or commercial furnace cement.

6. Test all gas piping and connections for leaks using a soap and water solution. Bubbles forming indicate a leak. Never use an open flame for leak testing.

Overfiring is a condition where excessive temperatures are reached beyond the design capabilities of the appliance. It can permanently damage your fireplace system.

Conditions that cause overfiring include:

Burning quantities of scrap lumber, pine branches, paper, or cardboard boxes which exceed the volume of a normal log fire.

Burning trash, chemicals, or chemically treated combustibles.

Symptoms of overfiring include:

A glowing fireplace or chimney connector.

Cracking, warping, or burning out of components.

Plated accessories turning color.

Appliance glass developing a haze that will not come off with cleaning.

When using glass doors with the SUPERIOR WCT2042WSI, adhere to these operational and maintenance instructions:

Operation: Doors must be in the fully opened or fully closed position only while the fireplace is in operation. If left partly open, gas and flame may be drawn out of the fireplace opening, creating fire and smoke risks.

Safety: Do not slam or strike the doors. Discontinue use immediately if the doors are damaged and contact a qualified installer for repair. Only doors certified with the appliance shall be used.

Cleaning: Clean the glass with any commercial glass cleaner or soap and water. Do not use any abrasive material. Do not clean the glass with cool water if the glass is still hot from fire and smoke.

Warming: The glass must be allowed to warm slowly and evenly. Keep fires back from the doors and never allow flames to contact the glass.

When wood is burned slowly, it produces tar and organic vapors that combine with moisture to form creosote. This residue accumulates on the flue lining and, if ignited, can cause an extremely hot chimney fire.

The chimney shall be inspected at least twice a year during the heating season to determine when creosote buildup has occurred. When creosote has accumulated 1/8 inch (3 mm) or more, it must be removed to reduce the risk of a chimney fire.

If the fireplace continues to smoke, check the following possible reasons:

Negative pressure in the house: Air going up the chimney must be replaced. Open a nearby window temporarily to see if it improves the draft.

Blowers operating: Range hoods or other exhaust fans can draw air out of the house. Turn off all blowers and open a window to determine if this is the cause.

Wet wood: Wet or tarred wood will smolder and smoke instead of burning. Use properly seasoned hardwood.

Dirty or blocked chimney: Ensure the chimney is clear and clean. Use a properly sized chimney brush or call a certified chimney sweep.

Chimney not long enough: The minimum chimney height is 12 feet (not including the appliance height). It must extend at least 3 feet above the point of contact with the roof and 2 feet higher than any part of the roof within 10 feet.

Poor chimney draft: To test, light a piece of paper and hold it in the upper part of the firebox to warm the chimney. Once the draft is sufficient, start the fire.

Properly seasoning wood is essential for efficient burning and reducing smoke. Use a firewood moisture meter to ensure the wood contains less than 20% moisture. Follow this guide:

Softwoods: Season for 6 months to 18 months.

Hardwoods: Season for 12 months to 24 months.

Preparation: Logs that are 5 inches in diameter or larger should be split in half. Logs over 8 inches should be split into three pieces, and logs over a foot across should be split into four pieces. Even if a tree has been dead for 2 to 4 years, it still needs to be cut, split, and seasoned for 6 to 24 months depending on the wood type.

The lineal gain is the actual measurable length of a part after two or more parts are connected. Refer to this table from the PDF:

Proper venting is critical for the performance of the SUPERIOR WCT2042WSI. Key requirements include:

1. Minimum Height: 14.5 feet for a straight flue or a flue with one elbow set. For systems with two elbow sets, the minimum height is 22 feet.

2. Maximum Height: 50 feet for any system.

3. Elbow Offsets: A maximum of two 6-foot angle run sections is allowed per chimney system. All pipe connections between offset and return must be secured with two screws on the outer pipe only. Do not penetrate the inner stainless pipe.

4. 10-Foot Rule: All flue gas outlet chimney terminations must extend a minimum of 3 feet in height above the highest point where it passes through the roof and must be at least 2 feet above the highest point of the roof that is within a horizontal distance of 10 feet.

5. Firestop Spacers: Required at each point where the chimney penetrates a floor space to maintain clearance between the chimney and combustible materials.

According to the PDF, Canadian code CAN/ULC-S610-M87 requires stainless steel chimney components. The following 8 inch Hi-Temp wood burning chimney parts are approved:

The SUPERIOR WCT2042WSI is a natural draft appliance. For optimum performance, the following draft conditions should be met:

1. Measurement: A draft test should read greater than .04 inches water column (W.C.) and less than .08 inches W.C.

2. Factors Affecting Draft: Chimney length, local geography, and nearby obstructions. Too much draft can cause overfiring, while inadequate draft leads to poor combustion and smoking.

3. Poor Draft Conditions: These can be caused by a chimney that is too large, insufficient chimney height, excessive chimney height (causing exhaust to cool and stall), or overly restrictive offsets.

Negative pressure occurs when air is exhausted from the home faster than it can be replaced, which can cause back drafting. In the SUPERIOR WCT2042WSI, this can be addressed by:

1. Identifying sources: Kitchen exhaust fans, furnace cold air returns, and clothes dryers are common sources of negative pressure.

2. Providing makeup air: Ensure the home has adequate makeup air to eliminate negative pressures. Opening a window on the windward side of the house can help.

3. Outside Air Kit: Installing an outside air kit (Model AK4 or AK4F) can provide a direct source of combustion air, although it may not resolve all negative pressure issues if the house is extremely airtight.
