Firestop Spacers - Vanguard Aristocrat V36E Installation Instructions Manual

STEP 4: When the fireplace is installed upon a combustible floor a
galvanized sheet ember protector (provided) must be installed between
the fireplace and the hearth extension as illustrated in Figure 16, page 6.
STEP 5: Secure the fireplace to the framing through the flanges
located on the sides on the fireplace with 8-penny nails.
NOTE: The 3/4" clearance is not required at the nailing flange (see
Figure 18).
ASSEMBLING AND INSTALLING YOUR
DOUBLE-WALL CHIMNEY SYSTEM
Each double wall chimney section consists of an outer pipe, flue pipe
and one wire spacer. The pipe sections are not united and must be
assembled independently as the chimney is installed. When starting
the chimney directly on the fireplace, the flue pipe section must be
installed first, with the hemmed end down. The outer pipe section
can then be installed over the flue pipe section with the hemmed end
up (see Figure 4).
Press down on each pipe section until the lances on the lower end
securely engage the knurl on the fireplace starting collar. The wire
spacer will assure the proper figure spacing between the inner and
outer pipe sections.
WARNING: THE OPENINGS IN THE COLLAR AROUND
THE BASE OF THE CHIMNEY AT THE TOP OF THE
FIREPLACE MUST NOT BE OBSTRUCTED. NEVER
USE BLOWN INSULATION TO FILL THE CHIMNEY
ENCLOSURE (SEE FIGURE 5).
Continue to assemble chimney sections as outlined above, making
sure that both inner outer pipe sections are locked together. When
installing double wall "snap lock" chimney together, it is important
to assure the joints between the chimney's sections are locked. Check
by pulling chimney upward after locking. The chimney will not
come apart if properly locked. It is not necessary to add screws to
keep the chimney together.

FIRESTOP SPACERS

Firestop spacers are required at each point where the chimney
penetrates a floor or ceiling joist space. Their purpose is two fold;
they establish and maintain the required clearance between the
chimney and combustible materials.

They also provide complete separation from one floor space to
another floor or attic space as required by most codes.
When the double wall pipe passes through a framed opening into an attic
space, the firestop must be place into the attic floor as in Figure 6.
When the pipe passes through a framed opening into a living space
above, the firestop must be placed onto the ceiling from below as in
Figure 7.
SUPPORT SECTIONS
"
8
The chimney support section is a 4-strap 12" length of pipe. A chimney
"
support is required every 30 feet above the fireplace after a straight
8
" chimney run, or above a return elbow after a straight chimney run (see
8
Figure 8). This support is designed to relieve the extra weight load on
"
8
the fireplace and elbow when high chimneys are installed.
