624WBPF Woodburning Fireplace CHIMNEY CAP INSTALLATION

NOTE: The proper height as previously explained is important to assure proper draft and safety. The chim- ney cap extends the flue outlet four inches above the top of the last section of chimney. This should be kept in mind when determining the proper height for the chimney. The chimney should not be extended more than 90 inches above the supporting roof structure without additional support. In the case of an ‘A’ frame type construction or other steep pitch roofs that require more than 90 inches of chimney above the roof, a support should be attached to the chimney at the 90 inch level that is strong enough to support a wind load of 3Z\, pounds for each inch the chimney extends above 90 inches. The flue outlet must be a minimum of three feet above the point where it penetrates the roof.

CAUTION: Be careful to avoid electrical shock hazard when contacting wires to the metal chimney com- ponents.

1.Extend the regular chimney sections until the top of the chimney is 4” below the total flue height desired. Do not snap the last section of inlet air duct or largest diameter pipe in place until Step 3 is completed.

2.Remove the shingles from around the chimney so that the flashing may be installed, with the upper part of the flashing under the shingles.

3.Set the flashing on the roof. Hold a section of the outside pipe (13” diameter) on the flashing and scribe a line around the flashing, then cut the top off the flashing by cutting 1/4 inch below the scribed line. This should increase the diameter of the flashing outlet sufficiently to allow the flashing to be placed over the chimney. Figure 18

4.Snap the last section of inlet air duct in place and slide the flashing over the chimney. Adjust the chimney to assure that the proper minimum clearances are maintained.

5.Nail the flashing securely in place with eight nails.

6.Seal the crack between the top of the flashing and the chimney with mastic. Leave some excess mastic at this area to be used in step eight. NOTE: Use pliers and wear gloves when performing step seven to minimize the danger of cutting your hands on the edge of the storm collar.

7.Place the storm collar around the chimney and put the collar together like a belt in belt loops. Slide the end of collar under the two loops on the other end with the loops facing up. Overlap the ends of the collar until it is tight against the chimney. Bend the free end of the collar back over the loops to hold the storm collar securely together. The excess end of the storm collar may be trimmed off.

8.Slide the storm collar down snugly against the flashing until the excess mastic left in step six is forced up into the crack between the storm collar and the chimney. This should make the joint between the flashing and the chim- ney watertight.

9.Install the chimney cap by placing the cap into matching parts of the last chimney section. Then punch or drill 1/8 inch diameter holes in the inlet air duct (chimney pipe) where specified on the brackets and fasten it down with the No. 8 screws provided. Do not penetrate the inner stainless steel pipe while installing the screws.

10.Check all the parts of the fireplace, chimney and chimney termination cap to assure that no parts have been dam- aged or bent during installation and that all parts have been installed properly.

NOTE: The metal used for the chimney cap has a rust pro- tective coating but the cut edges of the parts are not pro- tected. To prevent rusting and rust staining of nearby struc- tures, exposed parts of the chimney and chimney cap should be detergent washed and painted with a galvanized primer paint.
