E36/39/42 INSTALLATION INSTRUCTIONS
6. Attic Insulation Shield
An insulation shield should be installed when there is a possibility of insulation coming into contact with the factory built chimney system.
a.Bend the tabs at the top of the attic insulation shield inward. This will help keep the chimney section centered in the shield.
b.Position the shield over the vertical chimney section where it penetrates a firestop spacer.
c.Slide the shield down until it rests on the firestop spacer. The firestop spacer will support the insulation shield. See Figure 12.
Figure 12 - Installing an Attic Insulation Shield
WARNING! RISK OF FIRE.
Do not fill the space between the chimney sec- tion and the insulation shield with insulation.
7. Double-check the Chimney Assembly
Continue assembling the chimney sections up through the firestop spacers as needed. While doing so, be aware of the height and unsupported chimney length limitations that are given on page 12 under “Chimney Requirements”.
Check each section by pulling up slightly from the top to ensure proper engagement before installing the succeeding sections. If they have been connected correctly, they will not disengage when tested.
CAUTION:
Inner flue and outer liner sections cannot be disassembled once locked together. Plan ahead to ensure the proper installation height is achieved with the selected chimney compo- nents.
8. Secure the Chimney System
When offsets and returns are joined to straight pipe sections, they must be locked into position with the screws provided (outer only), using the predrilled holes. To prevent gravity from pulling the chimney sections apart, the returns and the chimney stabilizers have straps for securing these parts to joists or rafters. See Figure 13.
Note: You must provide support for the pipe dur- ing construction and check to be sure inadvertent loading has not dislodged the chimney section from the fireplace or at any chimney joint.
Figure 13 - Offset/Return with Stabilizer
WARNING!
When chimney sections exceeding 6 ft in length are installed between an offset and return, structural support must be provided to reduce
WARNING!
Maintain a minimum of 2 in. air clearance to all parts of the chimney system at all times! Failure to maintain this 2 in. air clearance will cause a structure fire.
