CHIMNEY CAP INSTALLATION (CONTINUED)

CHIIMNEY INSTALLATION

CHIMNEY CAP INSTALLATION (CONTINUED)

CAUTION

Be careful to avoid electrical shock

 

 

hazard when contacting wires to the

 

metal chimney components.

 

 

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. Install the upper part of the flashing under the shingles.

3.Set the flashing on the roof. Scribe a line around the flashing. Cut 1/4" below the scribed line. This should increase the diameter of the flashing outlet enough to allow the flashing to be placed over the

chimney. See Figure 25.

Line chimney. See Figure 25.Figure 25 - Cutting Off Top of theFigure 26 - Installing Storm Collar

9.Place chimney cap into matching parts of the last chimney section. Push chimney cap down until the brackets on the bottom of the chimney cap sits on the chimney pipe. Punch or drill 1/8" diameter holes in the inlet air duct (chimney pipe) where specified on the brackets. Fasten chimney pipe down with the No. 8 screws provided. Note: 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. Make sure none have been damaged or bent during installation. Check to see that all parts have been properly installed.

Note: The metal used for chimney cap has a rust-protective coating but the cut edges of the parts are not protected. Detergent-wash and paint exposed parts of chimney cap with galvanized primer paint. This will prevent rusting and rust staining of nearby structures.
