COAL: Some coals contain large quantities of sulphur (up to 7%). When coal is burned, sulphur and coal ashes are deposited in the chimney flue. This deposit combines with moisture to form a highly corrosive acid (sulphuric acid). In order to protect WARNING your chimney, we recommend that you: In Case of Fire: If a flue fire occurs, close all appliance 1. Burn only low sulphur coals (less than 1% draft openings, and call your Fire Department. Do not sulphur). use the chimney again, until it has been inspected for possible damage. 2. Have your chimney cleaned within 48 hours of shutting down your stove at the end of the heating season. Be certain that all the soot is removed. Wipe the chimney flue using a strong solution of baking soda and water. This can be done by wrapping a rag around a chimney cleaning brush, dipping it into the baking soda-water solution then passing it through the chimney three of four times. 2 NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Install the remaining chimney lengths, until INSTALLATION CALCULATIONS the required chimney height is reached. Determine the offset required in view of the obstacles that must be avoided (see Figure 13). Refer to Table 7 to determine the elbows required as well as the insulated length needed.

Step 9. If the chimney must pass through a soffit overhang above, cut and frame an opening Figure 17 according to the Roof Opening Chart shown in Figure 1. Important: Do not cut a truss! If desired, a firestop can be used to enclose the underside of the soffit. If using this part, be sure to follow the recommended framing STORM COLLAR requirements shown in Table 1 on page 3.

FLASHING WARNING: The clearance between the chimney and combustible material must not be less than 2”. Do not fill required air space in this area with insulation.

Step 10. Stack a chimney length on top of the tee. Turn it clockwise to lock it in place.
