Continue to assemble chimney sections as outlined above, making
sure that both inner and outer pipe sections are locked together.
Before installing double wall “snap lock” chimney together, it is
important to assure the joint between the chimney sections are
locked. Check by pulling chimney upward after locking. The chim-
ney will not come apart if properly locked. It is not necessary to add
screws to keep the chimney together.
SUPPORT SECTIONS
The chimney support section is a 4 strap 12” length of pipe. A
chimney support is required at the 30 foot level above the fireplace
after a straight on the fireplace and elbows when high chimneys are
installed.
WARNING: The opening in the collar around the
chimney at the top of the fireplace must not be
obstructed. Never use blown insulation to fill the
chimney enclosure (see Figure 3B).

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, and provide complete separa-
tion from one floor space to another floor or attic space as required
by most codes. When penetrating a floor or ceiling at an angle,
firestop in pack should be used.
Whenthedoublewallpipepassesthroughaframedopeningintoanattic

PENETRATING THE ROOF
To maintain a 2-inch clearance to the pipe on a roof with a pitch, a
rectangular opening must be cut.
STEP 1: Determine the center point through which the pipe will
penetrate the roof.
STEP2:Determinethepitchoftheroof.Pitchisthedistancetheroof
drops over a given span, usually 12 inches. A 6/12 pitch means that
the roof drops 6 inches for each 12 inches measured horizontally.
STEP 3: From the center point determined in STEP 1, measure an
opening 17 1/4inches wide (8 5/8inches to each side of the center
point). For a roof pitch between 0/12 (flat) and 6/12, measure an
opening 21 inches long (10 1/2inches above and below the center
point).
6/12 to 12/12 pitches: Measure 26 inches (13 above and below).
12/12to18/12pitches:Measure321/2inches(161/4aboveandbelow).
18/12 to 24/12 pitches: Measure 40 inches (20 above and below).
STEP 4: Remove the roofing around the opening measured and cut
out this section.
STEP 5: Add the next sections of pipe until the end penetrates the
roofline.Checktoseethatproperclearancesaremaintained.Extend
chimney by adding sections of double wall pipe until pipe is a
minimum of 30 inches above highest point of roof cutout. Termina-
tionandchimneymustextendaminimumof36inchesabovehighest

tions. If a chase termination is desired, refer to the instructions
supplied with the termination.
WARNING: Do not seal ventilation openings on the
rooftop flashing. Follow the installation instructions
provided with the termination being used.
FOR ROUND TOP TERMINATION ON ROOF
STEP1: Slide the flashing over the pipe (no firestopis needed at the
roof level). Tack the flashing down at the top two corners with
roofing nails. Lay roofing over the top and sides of the flashing and
secure them to the roof through the flashing with roof nails. Place
roofing under the lower edge and secure to the roof.
Cover all nail heads with mastic or roof cement.
STEP2:Installthestormcollarondoublewallchimney,pushcollar
down to flashing and seal (see Figure 9).
STEP 3: Place the CRTL-8DM on to the pipe end as illustrated and
secure with the screws provided.
IMPORTANT: If an exposed portion of chimney is greater than 5
feet above the roof line, use support wires to keep chimney secure.
The support wires may be attached to the outer pipe of the chimney
with screws, provided the screws are no longer than 3/4".

INSTALLATIONS
Before finishing the enclosure around the fireplace, inspect all joints
around the fireplace. Any gaps between the nailing flanges and the
framingshouldbesealedwithnoncombustibleinsulationorcaulking(see
Figure 10). Inspect the fireplace joints for possible gaps caused by
shippingor mishandling duringinstallation. These shouldbe sealed with
noncombustiblematerials.Ifthefireplaceismountedonaraisedplatform
insulate below the platform to prevent the entry of cold air through the
fireplace bottom by means of conduction. The above steps are import
