STEP 11. INSTALLING FLASHING
Place the flashing over the chimney pipe where it pene-
trates the roof and mark the outline of the flashing on the
roof. Remove the nails from the shingles inside this outline
and to the bottom edge of the roof cutout. Coat the roof
area under the shingles with roofing cement. Slide the flash-
ing under the shingles on the sides of the flashing and re-
nail the top and side shingles. DO NOT nail through the
lower portion of the flashing. If necessary, cover the side
and top of the flashing with the salvaged shingles. The
flashing should cover the lower side of the roof opening as
pictured in figure 18.
STEP 12. INSTALLING THE STORM COLLAR
The storm collar is assembled to the chimney system next.
Holding the adjustable storm collar with the tab of the collar
in your right hand, put the collar around the flue pipe. Push
the tab on the collar through the slot provided. Pull the tab
through and bend it just enough so that the collar may be
raised upward.
Apply waterproof caulking around the flashing where the
collar fits around the top of the flashing. Push the storm
collar down securely on the sealer and flashing. To secure
the collar, pull the tab through the slot as far as possible
and bend the tab over to hold it in place.
STEP 13. INSTALLING THE TERMINATION CAP
A chimney termination is required to finish the installation.
The following instructions are for the 82O3D termination.
Refer to the instructions packed with the termination for ad-
ditional information.
CHASE INSTALLATIONS
1. A chase is an enclosure for the fireplace and/or chimney
that is attached to the outside of the house. It may start
at the basement floor line, at the first level or at some
point on the side of the wall. A chase may also be used
to enclose a chimney from the point where it penetrates
the roof, to slightly below the termination cap.
2. The floor under the fireplace must be a solid, continuous
level surface. Many local building codes also require a
firestop spacer in the chase at the ceiling level in the
house. Consult your local building codes to determine
the requirements for chase installations in your area. Re-
member that all chimney components must have an ab-
solute minimum of 1" air space from combustible materi-
als. Plan the dimensions of your chase accordingly.
3. A chase should be constructed and insulated like any
other exterior wall in your home.
4. A metal cover made by a local sheet metal shop is re-
quired to complete a chase installation. This cover be-
comes a flashing that prevents water from entering the
chase. The chase cover should be sealed at the corners.
A minimum 1" high collar is required at the point where
the chimney pipe or slip section will penetrate the chase
cover. It requires 12 5/8" diameter collar for 36 " models,
13 5/8" for 39" and 42" models. The seam at the base of
the collar must be watertight. It may be necessary to sup-
port the chase cover with framing members if the cover
is large or has multiple caps. Required clearance to com-
bustibles must be maintained. Spacers (¼" high) should
be used to space the chase cover above the wood fram-
ing to minimize conduction of heat to the wood.
5. These fireplaces may be installed in a chase using Model
8203D termination cap. All sections of the chimney
must extend 6" above the chase cover when the
8203D termination Is used. Install the storm collar over
the 1" collar on the chase cover and caulk between storm
collar and pipe. The termination is installed to the chim-
ney pipe above the chase cover as described in figure 19.
6. If a flush mount is desired, model STD-22 Round Chase
Cap, ARC-52 or ARC-12 Architectural Caps. PRC-12 or
LPC-12 Pyramid Caps, or TCS12 Conical Cap may be
used. When used, the last chimney section must be no
more than 12" below the chase cover collar. All slip sec-
tions require a minimum 3" lap into the last chimney sec-
tion. Refer to separate installation instructions for each
termination for details.
7. It is recommended, but not required, that you insulate under-
neath the fireplace and between the studs on the outside
wall of the chase to reduce heat loss in cold climates. Be
sure to use noncombustible insulation without paper or plas-
tic backing. Never use blown-in type insulation in a
chase. Insulation should never cover the top or sides of
the fireplace or any part of the chimney system. To fur-
ther reduce heat loss, it is recommended that 1/2" gypsum
wallboard be installed over the insulation on the inside of the
chase. Plan chase dimensions accordingly.
8. Chases with two or more chimneys should be con-
structed wide enough to allow chimneys to be spaced at
least 24" on center from each other. When chimneys are
closer than this, smoke from one may be drawn down
the
flue of the adjacent chimney. When chimneys must be
installed closer than this, smoke transfer may be pre-
vented by vertically offsetting adjacent terminations by
12" to 18" or by installing 12" to 18" high sheet metal
