floor separation through which the chimney

will pass. At the attic level, install an attic

radiation shield from above (Figure 24a).

chimneys place the first chimney length on

the fireplace. To lock it in place, turn 1/4 of

a turn clockwise. With the AC chimney, you

Every time the chimney passes through

 

a ceiling or a wall, install the appropriate

 

firestop. When you reach the desired height,

 

install the roof support (Refer to instructions

 

included with the support).

5.

Then, put the roof flashing in place and seal

 

the joint between the roof and the flashing

 

with roofing pitch (see Figures 26 and 27).

 

For sloping roofs, place the flashing under

 

the upper shingles and on top of the lower

 

shingles. Nail the flashing to the roof, using

 

roofing nails.

6.

Place the spacers and the storm collar over

 

the flashing, and tighten it with the bolt

 

supplied. Finally, seal the joint between the

 

storm collar and the chimney, using silicone

 

caulking.

7.

Install the chimney cap.
