Attic Insulation Shield - Heat & Glo RHW-56 Installation & Operating Instructions Manual

RHW-56 INSTALLATION INSTRUCTIONS

6. Attic Insulation Shield

Æ
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 Insulation Shield
7. Double-checking 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 11 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.
Inner flue and outer liner sections cannot be
disassembled once locked together. Plan ahead
to ensure the proper installation height is
achieved with
components.
Æ
WARNING! RISK OF FIRE.
Do not fill the space between the chimney sec-
tion and the insulation shield with insulation.

8. Securing 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 during
construction and check to be sure inadvertent load-
ing 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 six feet in
length are installed between an offset and re-
turn, structural support must be provided to re-
duce off-center loading and prevent chimney
sections from separating at the chimney joints.
WARNING!
Maintain a minimum of 2” air clearance to all
parts of the chimney system at all times! Fail-
ure to maintain this 2” air clearance will cause
a structure fire.
