Attic Insulation Shield Installation; Firestop Radiation Shield Installation - Selkirk FC Installation Instructions, Warranty And Maintenance Manual

Generally, for a wood burning appliance installation, an 18" minimum
clearance to combustibles must be maintained for a single wall flue
pipe. The exception to this is a double wall stove pipe, such as
Selkirk's Model DSP which can be installed at reduced clearances of
6" to combustibles. See separate installation instructions for more
details.
Install additional chimney sections and lock together tightly. Install
a Locking Band to secure the two chimney sections together.
Continue adding chimney lengths until a height of about 2ft below
the next ceiling level is achieved.
ATTIC INSULATION SHIELD
An Attic Insulation Shield must be installed where the chimney enters
an attic space. It is designed to keep insulation materials away from the
chimney and will protect up to a 10 inch (250 mm) thickness of
insulation plus the depth of the ceiling joist.
Where height restrictions will not permit the use of the Attic
Insulation Shield, an enclosure from the attic joist to the roof joist
will be sufficient. All chimney enclosures must maintain the
required minimum air space clearance of 2" to the chimney. When
enclosing the chimney below the roof line, a Rafter Radiation Shield
(RRS) must be installed at the roof level and a Firestop Radiation
Shield (FRS) at the ceiling level (see Figure 6). For proper installa-
tion, the attic opening must be fully framed at 2 inches of clearance
to the chimney pipe with framing material of the same stock as the
ceiling joist and as per the Framing Dimension Table 1. The tabs on
the plate are inserted in the framed opening around the chimney.
Nail the AIS base to the framing with at least 2 per side, using 2d (1")
spiral nails or 1" x #8 wood screws.

Main Floor Installation
When an Attic Insulation Shield is required above the Decorator
Ceiling Support into an attic as shown in Figure 4, ensure that the base
of the shield is flush with the top of the joist framing and naile in place.
The telescoping portion of the AIS will eliminate the need to trim the
bottom when installed immediately above this support. When fully
extended, the AIS will also provide joist shielding when installed in a
2 story main floor or basement application (see Figure 7).
NOTE: To stop cold air infiltration into the dwelling you can install the
optional Universal Shielding Insulation (JUSI) into the Attic Insulation
Shield. See separate installation instructions packaged with the JUSI.
FIRESTOP RADIATION SHIELD
A Firestop Radiation Shield must be installed where the chimney
passes from one living space to another living space, as shown in
figure 7. It is designed to provide proper firestopping between floors
and to keep direct radiation from the chimney away from the joist
framing.
