Authorities require that the chimney extend not less than 3 feet
(900mm)abovethehighestpointwhereitpassesthroughtheroof
of a building and not less than 2 feet (600 mm) above any portion
of the building within 10 feet (3 m). See figure 1 and Chart 2.
The ideal location for your chimney is within the building
envelope. In cold climates, the use of external chimneys may
result in operational problems such as poor draft, excessive
condensation of combustion products and rapid accumulation of
creosote. Under these circumstances, the installation of the
chimney within the building is strongly recommended.
If the chimney must be installed on an exterior wall it is
recommended that the chimney be enclosed below the roof line
to protect the chimney from cold outdoor temperatures, this may
helpreducecondensation,creosoteformationandenhancedraft.
Provide an access door by the Tee Plug for chimney inspection
andcleaning. Theexteriorenclosuremaybeinsulated,maintaining
the required minimum air space clearance of 2" (50mm) to any
part of the chimney. Consult local building codes for cold climate
applications.
Do not install the chimney directly at the outlet of the appliance.
Interconnecting smoke pipe is required unless the appliance is
specifically approved for that type of installation.
Use only with an appliance listed by a recognized testing
authority such as Underwriters Laboratories Inc., Underwriters
Laboratories of Canada, Intertek Testing Services, Warnock
Hersey or ICBO.
The flue diameter of gas or oil fired appliances should comply
with the appropriate Installation Codes such as CAN/CSA-B139
or CAN/CSA-B149 when installed in Canada, and the Installation
Codes NFPA 54, ANSI Z223.1 and NFPA 31 in the United States.

YourCFSentinelchimneyandconnecting stovepipediametershould
be sized in accordance with the appliance manufacturer’s
recommendations.
Plan the installation of your appliance and chimney in such a way that
both your chimney and your chimney connector (stovepipe) run is as
short and straight as possible. By having too long and / or multiple
bend installations you can reduce system draft which can affect the
operation, and or performance of your appliance and or the chimney
system. Thechimney shouldbelocatedwithinthebuildingastoavoid
cutting or altering load bearing members such as joists, rafters, studs,
etc. Ifyouhavetocutoralteranexistingloadbearingmember,special
reframing methods are required which often include doubling of
adjacent members. If such a case arises, contact your local Building
Code Official regarding local regulations and proper installation
methods.
Before commencing the installation ensure that you obtain any
necessary building permits, and that your installation will conform with
all federal and municipal building codes requirement.
Sections of the CF Sentinel chimney which pass through accessible
areasof thebuildingsuch asthroughclosets,storageareas,occupied
spaces or any place where the surface of the chimney could be
contacted by persons or combustible materials must be enclosed in
a chase. The chase may be fabricated using standard building
materials. Drywall mounted on 2” x 4” studs is typically used in this
situation. Except for installation in single and two family dwelling,
factory-built chimneys shall be enclosed with approved walls having
a fire resistance rating equal or greater than that of the floor or roof
assemblies through which they pass. The space between the outer
wall of the chimney and the enclosure shall be at least 2 inches.

Situate the chimney in the structure so that it can be installed
without cutting joists, sills, plates or load bearing partitions or
members.
Connect only one appliance to a chimney.
There should be no draft regulators on solid fuel equipment and
smoke pipe connector.
A minimum smoke pipe connector length of 3 feet (1 m) between
appliance and chimney is recommended.
Your CF Sentinel chimney system is designed for installation
using standard building materials and procedures. The following
tools may be required:
TOOLS
-safety gloves
-safety goggles
-hammer and nails
-tin snips
-tape measure
-screwdriver and pliers
-plumb line and level
-square
-keyhole saw or power jig saw
-caulking gun
Other tools or equipment may be required, depending on your
chimney location and the structure in which it is to be installed.
CF SENTINEL JOINT SECURITY:
High internal gas temperatures in a chimney force the internal
pipe to expand or lengthen. This, in turn, may cause the joints
to separate if they are not securely locked. The use of a chimney
cleaning brush may also cause the joints to separate if not
securely locked.
INSULATION COMPRESSION OF THE CF SENTINEL
Beforeassembling chimney lengths to one another, the insulation
on the female end (held in place with a plastic retainer) should be
below the outer bead so that it can compress during assembly.
The upper side (male end), should be full of insulation (held in
place with a white paper retainer and a web coupler) to the top of
the length. Once you have assembled the lengths together, a
locking band must be installed. With the insulation being
compressed, this will provide insulation to insulation contact (see
Figure 2).
NOTE: Whentheinsulation retainersmeltorvolatilize duringhigh
temperature operation, the compressed insulation will fill in.

Plan your installation carefully. If possible, position the stove so
that the flue outlet is centered between joists or rafters. Drop a
plumb line to the center of the flue outlet and mark this center
point on the ceiling. Lay out and frame in all openings ensuring
the specified 2” clearance to combustibles is maintained. Refer
to Table 1 or applicable Tables for framing dimensions and mark
the appropriate cutting lines around the center point.
FRAMINGDETAILS:
2. To remove the lockband, the clasp is pushed in and then
unhooked (see Figure 3B). Lift the clasp with a screwdriver if
necessary.
3. When a chimney section is suspended e.g: below a Cathedral
Ceiling Support, the band(s) and the joints must be fastened
using two (2) #6 x 1/2" stainless steel sheet metal screws (see
Figure 4).

INSTALLATION PROCEDURES:
TheCFSentinel Ceiling Support will support up to 40feet(12.2m)
of chimney sections, all of which must be installed above the
support. Figures 10 & 11 illustrates the 2 most common types
of Ceiling Support Installation.
Frame (on all 4 sides) a level square opening with the inside
dimensions 14-1/4" (362 mm) square.
With the Lower Bucket removed, place the Ceiling Support
Assembly into the framed opening from below at the ceiling level
(see Figure 7).
The stub end (crimped) of the Smoke Pipe Adapter is intended
to fit inside of the connector pipe from a solid fuel appliance, thus
preventing condensate drips at the chimney connection.
Install inter-connecting stove pipe following appliance
manufactruer's instructions and appropriate building code re-
quirements keeping in mind that the stove pipe run should be as
short and straight as possible and secured in place with a
minimumof 3sheetmetalscrews per joint. Generally, for a wood
burning appliance installation, an 18" minimum clearance to
combustibles must be maintained for the stove pipe. NOTE: The
exception to this is a double wall stove pipe, such as Selkirk's
Model DSP which can be installed at reduced clearances to
combustibles. See separate installation instructions for more
details.

FIRESTOP JOIST SHIELD (JS)
A Firestop Joist Shield (JS) must be installed where the
chimney passes from one living space to another living space as
shown in figure 11. It is designed to provide proper firestopping
between floors and to keep direct radiation from the chimney away
from the joist framing.

Firestopping is required at every joist level. Wherever a chimney
passes through a ceiling or floor, through a wall, or into an
enclosure, it must be firestopped. No firestopping is required in
conjunction with a Ceiling Support installed as shown in Figures
11, the Ceiling Support provides the firestopping.
A fire stop performs the following essential functions for both
dwelling and the chimney:
- Together with a fully framed opening (all four sides), it controls
vertical and horizontal spread of any fire external to the chimney.
- It stabilizes the chimney in the framed opening and defines and
maintains the required AIR SPACE clearance to combustibles.
- It reduces heat losses from the dwelling by blocking vertical air
circulation in the spae around the chimney.
- When located at a ceiling below a roof flashing (or below a roof
support) it helps provide stability for chimney extending above the
roof.
- At the level where the chimney penetrates the air/vapour bariier,
special attention is required. Seal the vapour barrier to the Ceiling
Support, Attic Shield (Joist Shield if the chimney is enclosed in the
attic) or Wall Thimble using an appropriate caulking compound as
per the requirement of local authorities.

The Attic Insulation Shield (AIS) provides 2 features: it comes
fully assembled with a built-in telescoping bottom shield,
eliminating the need for field assembly.The function of the Attic
InsulationShield(or a complete enclosure) is to keep insulation from
coming into contact with the chimney. Certain insulations made
of cellulose fiber (old newspapers, processed wood) may ignite
and smolder due to heat trapped by contact with the chimney.
When this smoldering fire reaches ordinary wood framing, a
flaming fire may resuilt. However, even without a flame, a
smoldering fire may create noxious gases and cause great
property damage.
An Attic Insulation Shield (AIS) must be installed where the chimney
enters an attic space. The Attic Insulation Shield is designed to
keep insulation materials from coming into contact with the chimney
and will protect up to a 10 inch 250mm) thickness of insulation plus
thedepth of the ceiling joists. If insulation is blown in and adheres
to the chimney pipe, it should be brushed off to eliminate any
possible contact of this material with the chimney when it is in
use.
The height of the AIS must accomodate the amount of insulation
as required by the National Building Code. Where height
restrictions will not permit the use of the Attic Insulation Shield, it is
permissible to construct an enclosure with the required minimum
air space clearance of 2" (50mm) to the chimney all the way to the
underside of the roof deck. In this application you will install a
Firestop Joist Shield (JS) at the ceiling level, with the exception of
a Single Story Installation (see Figure 13).
ATTIC INSULATION SHIELD (AIS)
Nail the AIS base to the framing dimensions with at least 2 per
side using 2d (1") spiral nails or 1" x #8 wood screws.

Fully frame a level square opening (all four sides) for 2" ( 50mm)
clearance from the outside of the chimney to the inside of the
frame. Place the Firestop Joist Shield (JS) up into the framed
opening from below the joist framing and nail in place using 1"
spiral nails as per Figure 10. Ensure no insulation or debris is
within the 2" air space clearance around the chimney. This
includes the air spaces between the Firestop Joist Shield (JS)
and the joist framing.
When the chimney is enclosed in the attic area, a Firestop Joist
Shield (JS) must be installed at the ceiling level. If the base of the
Firestop Joist Shield (JS) does not fit flush with the ceiling frame,
measure the distance that the base is sitting below the framing
and trim that amount off the top of the Firestop Joist Shield (JS)
before securing into place.

For proper installation, the attic opening must be fully framed at
2 inches of clearance to the chimney pipe with framing material
of the same dimension as the ceiling joists (as per Framing
Dimension Table 2). The tabs on the base plate of the AIS are
inserted in the framed opening around the chimney. NOTE: This
only applies to the 6" AIS. On the 7" and 8" AIS, the tabs will
require to be flattened out and the AIS centered over the
framed opening.
When an Attic Insulation Shield is required above the Ceiling
Support into an attic as shown in Figure 13, ensure that the base
of the shield is flush with the top of the joist framing and nailed in
place. The telescoping portion of the AIS will eliminate the need
to trim the bottom when installed immediately above this support.
When fully exended, the AIS will also provide joist shielding when
installed in a 2 story main floor or basement applications (see
Figures 11 & 15).

WALL SUPPORT (WSP)
To complete a proper Wall Support installation, the following parts
may be required:
- Wall Support Package: - Intended for a through-the-wall installa-
tion where the chimney has a lateral connection.
- Adjustable Roof Flashing: - Required when the chimney
penetrates a roof or a roof overhang.
- Insulated Tee: - Required when the chimney is installed through
and along a vertical wall either on the exterior or interior.
- Wall Bands: - Required to provide lateral support to the chimney.
- Suitable lengths of chimney: - The chimney diameter should be
sized to suit the appliance.
- Interior Wall Plate and Exterior Wall Plate: - Required when going
through a combustible wall.
- Insulated Wall Thimble: - Required to satisfy through-the-wall
installation where framing an opening may not be practical.
- Round Top: - To exclude rain and/or leaves into the chimney.
The CF Sentinel Adjustable Wall Support will support up to 40 feet
(12.2 m) of chimney, all of which must be above the support.
1. Determine the center line of the lateral connection (horizontal
length through the wall) and frame in your opening to the dimen-
sions specified in Table 3. For a non-combustible wall (concrete
blockor pouredfoundation),cutahole 1/8"greaterthantheoutside
diameter of the chimney as per Table 3. DO NOT PLACE ANY
LOOSE INSULATION around the horizontal chimney length within
the framed opening when using a Wall Plate Spacer or Insulated
Wall Plate Spacer. Maintain the required minimum 2" (50mm) air
space clearance to combustible materials.
2. Assemble braces, brackets and angles to the base plate using 1/
4" nuts and bolts, with braces up or down as necessary (DOWN IF
CHIMNEY GOES THROUGH WALL) as per Figure 19 & 20a and if
it is an interior wall support installation (Figure 20b).
3. Nailbracketsand angles to framing temporarily making sure that
the base plate is level (and positioned to allow for the installation
of the wall plates, if the chimney goes through the wall).

WALL BAND INSTALLATION (WB)
1. The required 2" (50mm) minimum clearance is established by
the 1-3/4" center (carriage) bolt. Place the 1-3/4" carriage bolt
through the center offset of the band half nearest the wall. Place
single hole ends of the perforated straps over this bolt. Install nut
tight against strap so that straps are horizontal (as per Figure 22).
2. Clamp the two halves of the support band around the chimney
pipe using the long bolts through the band end tabs. First install
the pivot screws.
3. Place the wall brackets (long slotted parts) over the pivot
screws projecting out from the end tabs and hand tighten.
4. Line up the perforated straps and wall brackets, then mark
position on wall for lag screws or anchors to go through both the
straps and brackets.
9. After checking fit, secure Tee to integral basecap of base plate
with a locking band. Install the Tee Plug and turn the two (2) twist
lugs.
10. Use a non-hardening high-temperature sealant (500oF) to
seal around the exterior portion of the horizontal chimney length
where it enters one of the following: Exterior Wall Plate, Insulated
Wall Thimble or a concrete wall.
11. NOTE: Only CF Sentinel chimney must extend through-the-
wall. Use the Wall Plate Spacer (or the interior portion of the
Insulated Wall Thimble) on the interior wall to center and support
the horizontal extension. Remember that the chimney pipe
length selected must extend at least 3" (76mm) beyond the wall
and must be centered in the wall opening. The maximum length
of pipe out from the wall is 39" (990mm).
12. Chimney lengths above the Tee are simply stacked and
secured in place with the supplied Locking Bands.
13. To ensure chimney stability above the wall support, Wall
Bands must be used at every 8 to 12 feet (2.4 to 3.6m) intervals
above the support.
8. If the Tee and the Chimney will be fully enclosed in a chase or
shaft or the wall is non-combustible, the exterior wall plate need
not be used.
7. Place this whole assembly (Insulated Tee, Chimney Length
and Exterior Wall Plate) into the wall opening and onto the base
to check centering and clearances. Make sure there are no
interferences. If the Tee is outdoors, keep in mind that the louver
openings in the Exterior Wall Plate must be down to keep the rain
out.

The bottom chimney length(s) must protrude into the living space
so that proper clearances are maintained from the stove pipe
connector to the lower side of the ceiling (see Chart 3 in the back
of these instructions for more details). Do not offset the CF
Sentinel chimney below the Cathedral Ceiling Support Box.
Install additional chimney lengths with locking bands until the
required height above the roof is achieved. NOTE: As previously
mentioned, when a chimney is suspended below the box, locking
bands and joints must be fastened using two (2) #6 x 1/2"
stainless steel sheet metal screws (as per Figure 4).

the band deflects the chimney outer casing. Secure the band to
the chimney outer casing by screwing the eight (8) stainless
steel sheet metal screws through the draw band and into the
outercasing (for ease of attachment use a 3/32" hole). Lower the
chimney length down through the opening in the bottom of the
Support Box, so that the Support Band makes contact with the
bottomoftheSupport Box (See Figure 23).NOTE: The maleend
NOTE: If the chimney penetrates an overhang (soffit) cut an
opening with 2" clearance all around and install a Joist Shield on
theundersideoftheoverhang. Iftheatticisopentotheoverhang,
close off the access with suitable building materials ensuring that
a 2" (50mm) air space is maintained. From above install a roof
flashing and storm collar by following the Roof Flashing installa-
tion section. If the overhang is not deep enough to allow the
chimney to be fully installed within the overhang, it will be
necessary to cut away the overang. Ensure that a 2" (50mm)
clearance all around the chimney is respected. Framing and
flashing the sides of the opening will be required. Install a Wall
Band at this level.
To complete a proper Cathedral Ceiling Support installation, the
following parts are required:
- Cathedral Ceiling Support: - Includes a painted black support
box, a two-piece support band, 4 painted ceiling trim angles (2
short, 2 long), decorative sleeve, smoke pipe adapter and
hardware package.
- Roof Flashing Assembly:- Required when the chimney pen-
etrates a roof.
- Suitable lengths of chimney: - The chimney diameter should
be sized to suit the appliance.
- Round Top:- To exclude rain and/or leaves into the chimney.
The CF Sentinel Cathedral Ceiling Support will support a total of
15feet (4.6m)ofchimney,ofwhich10ft(3m)canbesupportedbelow
the box. When a chimney is suspended below the box, the locking
bands and joints must be fastened using two (2) #6 x1/2" stainless
steel sheet metal screws (drill 3/32 holes) as per Figure 23.
CATHEDRAL CEILING SUPPORT (CCB)
The Cathedral Ceiling Support Box is manufactured to an overall
outerdimension of 1/8" (6mm) less than the minimum dimensions
specified in the Framing Details section (Table 1) and 17-1/2"
(444mm) in height.
After framing in your opening to the dimensions specified in the
Framing Details section, slide the Cathedral Support box into the
joist opening. Once the box is at the desired level, ensure that
theboxislevelandnailtheboxtotheframing using three 2" spiral
nails or #8 x 1-1/2" wood screws per side. The excess material
sticking above the roof can either be trimmed off before attaching
the box to the framing or, after it is installed, the corners can be cut
and the excess material folded down and secured onto the roof
deck.

2. Form the Band into a circle and loosely connect both tabs
using the supplied 2” bolts into the 2 cage nuts (see Figure
25a).
3. Attach the Support Plates to the band with flat head bolts (2
sets per plate) washers and nuts. The bolts should pass
through the holes in the band corresponding to the pipe
outside diameter and secured loosely (see Figure 24 & 25A).
NOTE: 2 sets per Support Plates.
4. Place assembly around the length of pipe and loosely tighten
the tabs with the screw and nut referenced in Step 2. Move
the assembly to the desired height location on the pipe.
Firmly tighten bolt and nut to secure the band around the
pipe.
5. Secure URSA to the length of pipe by using four (4) 1/8” x 1/

On steep roofs, it is recommended that an ice deflector or cricket
fabricated from heavy-gauge galvanized steel be installed. The
wedge-shaped deflector is installed against the chimney on the
upper slope. Its function is to split ice and snow as they slide
down the roof, preventing damage to the chimney. This is not a
supplied item. Contact a sheet metal fabrication shop in your
area for your custom ice deflector.
The flashing and storm collar should be painted to match the roof
shingles. This will extend its life and improve the appearance.
The chimney may be painted also with a HEAT RESISTANT
paint. ToimproveadhesiontotheCFSentinelchimney,degrease,

“Creosote and Soot - Formation and
Need for Removal”
MAINTENANCE AND CLEANING OF
THE CHIMNEY:
The need for chimney maintenance depends on the kind of
appliance and how it is operated. Gas and oil-burning appliances
need very little, but wood-burning appliances may need a great
deal of chimney maintenance.
How you burn wood in your stove or fireplace directly affects the
formation of creosote. Use more dry kindling and paper first to
warmupthe chimney system to a temperature between 350 to500
F. Burn hot, bright fires and fire each load hot. It is important to
load your appliance properly and to avoid smoldering fires. Fast,
effective start-ups are important, as is the moisture content of the
wood being burned. If your wood is not completely seasoned, split
your wood in smaller pieces instead of larger ones. Ideally, the
moisture content of your firewood should be between 18 to 22%.
A good investment in assisting you in monitoring your system is
a surface thermometer for single wall stove pipe or a probe
thermometer for double wall stove pipe. Ensure only low sulphur
content coal (1% or less) such as anthracite is burned.
When wood is burned slowly, it produces tar and other organic
vapors, which combine with expelled moisture to form creosote.
The creosote vapors condense in the relatively cool chimney flue
of a slow-burning fire. As a result, creosote residue accumulates
on the flue lining. When ignited, this creosote creates a chimney
fire with extremely high temperatures.
With a new installation, the chimney should be inspected
frequently(every2wks)todeterminetherateofcreosoteformation.
When familiar with the appliance and chimney characteristics, the
chimney should be inspected at least once every 2 months during
the heating season to determine if a creosote or soot build-up has
occurred. Check spark arrestor screens at least every 2 to 4
weeks. If the spark arrestor becomes clogged with creosote, it
should be cleaned or replaced.
If creosote or soot has accumulated, it should be removed to
reduce the risk of chimney fire. Depending on the rate of buildup
(aslittleas1/16")andasyoulearnwhatisgoingonin the chimney,
you can adjust your cleaning schedule accordingly. Every
chimneyflueandflue pipe shallbeinspectedannuallyandcleaned
as often as may be necessary to keep the chimney and flue pipe
free from dangerous accumulation of combustibles.
Chimney and flue pipe are particularly susceptible to off-seasn
condensation. The incomplete combustion of wood produces
acids which, when combined with moisture, are corrosive. During
the heating season, corrosion tends not to occur because the heat
in the system evaporates the condensation of any water vapour
that may be formed.
Warm, moist air during the summer months passes slowly
through the heating system. It makes any remaining ash or
creosote moist and soggy. Corrosion of steel occurs where these
deposits remain.
Off-season corrosion can be reduced considerably if the system
is thoroughly cleaned after the last fire of the heating season.
Where coal is burned, the system must be thorougly cleaned
within 48 hours of shutting down the system for the season and all
soot be removed from the chimney system. this should be the
Contact a professional certified chimney sweep for chimney
cleaning services and advice if you have any doubts about your
ability to clean your chimney system or if the task is too large.
If chemical cleaner is used to assist in cleaning your chimney,
make sure it is a product which is non corrosive. Selkirk will
assume no liability for damage resulting from the use of chemical
cleaners. It does not replace the need for a mechanical cleaning.
The optimal method for cleaning a chimney is by a mechanical
brushing of the chimney in conjunction with a complete evaluation
by a certified chimney sweep.
CHIMNEY FIRES AND WHAT TO DO ABOUT THEM
Your CF Sentinel chimney is not intended or designed for use as
a combustion or fire chamber. It is very easy to over fire your
woodburning appliance with kindling, scrap lumber, brush or any
fast burning fuel. This can produce flames and high temperatures
all the way up the chimney,and may cause chimney damage. If
you see your appliance or the stove pipeglowing red, you are
risking chimneydamage, or a fire. The creosote may be burning
inside the chimney.
If you see flames coming out the top, you are either overfiring or
there is a chimney fire. The following materials should not be
burned in your woodburning appliance: pressure treated lumber,
rail road ties, salt water driftwood or plastic. Burning such
materials may lead to severe corrosion of the appliance and the
chimney system.
If the fire in your appliance has gotten out of control, or if you
suspect a chimney fire for any reason, follow these steps:
1. Immediately close all dampers and/or air entrance openings to
your appliance.This includes doors on Franklin type stoves. Block
off fireplace openings.
2. Alert your family to the possible danger.
3. Inspect your appliance and chimney surroundings for possible
fire. If in doubt, alert your Fire Department.
4. Do not continue to use your appliance until it and your chimney
have been thorougly inspected. Overheating can cause metal
parts to expand, buckle and crack. If you are not certain, have a
certified wood technician or certified chimney sweep disassemble
all parts so they can be inspected and replaced.
5. Do not use salt or water on the fire in your appliance. Salt is
corrosive and water will cause a dangerous steam explosion. You
might be able to control the fire by using ashes, sand or baking
soda, since baking soda is an ingredient used for dry chemical fire
extinguishers.
6. After a chimney fire, when it is safe to do so, check internal
locations such as the attic and under the roof and keep watching
for two or three hours. There may be delayed smoldering and
subsequent ignition, even if the fire inside the chimney has been
controlled.
To visually inspect the chimney, remove the Round Top by
loosening the the nut and bolt from the securing band. This will
permit the insertion of a flashlight for inspection and a properly
sized plastic chimney cleaning brush. A metal brush may scratch

The Tee Plug can be removed by turning the lugs to the side. Be
sure to replace the Round Top and the Tee Plug when you are
finished inspecting and cleaning the chimney.

BURN ONLY SEASONEDFIREWOOD!
Wood burns completely only at very high temperatures with
enoughoxygenpresent. Thefuel,heat, andoxygenhavetomix
together in the same place at the same time. Although all
stages of burning wood actually occur at the same time, it will
burn in 3 stages: boiling off the water, vaporizing wood gases
and burning the charcoal.
Wood burning appliances will burn best with clean, well sea-
soned dry firewood with an ideal moisture content of 18% to
22%. The denser or heavier the wood when dry, the greater its
heat value. Seasoned firewood is essential for an optimum
performance. Seasoned wood will burn hot, emit less smoke
and create less creosote.
Un-seasoned wood when burned, must release water stored
within the wood.This cools the fire, creates creosote and
hampers a complete burn. Be careful of wood advertised as
seasoned. You may want to invest in a moisture meter.
Signs of seasoned firewood are:
- Dark colored; wood darkens with age;
- Cracks in the end grain; radiating from the center of the log like
bicycle spokes;
- Light in weight; which indicates low moisture content - but
hardwood will weigh more than softwood;
- Sound; hit 2 pieces together, wet will have a dull "thud" sound
where as dry will ring like a bat hitting a baseball;
- Easily peeled or broken bark; no green should show under the
bark;
- Burn some; if it hisses, then it is to wet.
The time it takes to season wood varies from 6 to 18 months.
Hardwood dries slower than softwood and some may take well
over a year to dry. To speed-updrying:
- Cut to length;
- Split in a variety of sizes no larger than 6" exposing the wet
interior and increasing the surface area of each piece;
- Stack loosely in a criss cross pattern to get good air circulation;
- Store above ground at least a foot and away from buildings in
a sunny, well ventilated area;
- Cover the top to keep rain and dew off the wood;
- Leave sides open to breezes; for air circulation.
AVOID BURNING "green", "unseasoned" "wet" wood. Heat is
wasted as it must first dry and evaporate the moisture content in
the firewood. As the water evaporates it will form into creosote
which will then condense in the relatively cool firebox and
chimney and will not permit a clean hotburn.

Model CF Sentinel Anchor Plate provides a connection from a
masonry fireplace to a Selkirk Model CF Sentinel chimney. The
following steps describe the installation of this part (component)
and the above mentioned sections of these instructions are to be
followed.
1. Mount four (4) 1/4" diameter bolts, 3" long securely into the
top of the masonry fireplace around the outlet opening. Use the
4 holes on the anchor plate as a template to locate the placement
of these bolts.
2. Apply a bed of mortar approximately 3/4" in depth and 3" in
width completely around the fireplace opening. Make sure the
threadedendsoftheboltsprotrudeaminimumof1"abovethebed
of mortar.
3. While the mortar is still damp, place and level the Anchor Plate
overthe extended studs. Secure using a washer andnut for each
bolt.
4. Check the Anchor Plate for level and allow mortar to set.
5. Place the flue extension (crimped end down) into the opening
of the Anchor Plate. Place a section of chimney onto the Anchor
Plate and secure to the Anchor Plate with a Locking Band and
stainless steel sheet metal screws (see CF Sentinel Joint
Security section of these instructions and Figure 4). Up to 85 feet
of chimney may be stacked on the Anchor Plate.

"LISTED" FACTORY-BUILT FIREPLACES
When Selkirk chimney Model CF Sentinel is approved with a
"Listed" factory-built fireplace, the chimney and fireplace are
tested in combination as a complete system and the fireplace
instructions must be followed.
Where required in the "Listed" factory-built fireplace installation
instructions, an Anchor Plate can be used to provide a connection
from a "Listed" factory-built fireplace to the insulated chimney
Model CF Sentinel.

CHART 1 - OFFSET CHIMNEY INSTALLATION
When the chimney path cannot be perfectly straight, the need to install a chimney offset must be used when it becomes necessary
to offset the chimney in order to clear a joist or an obstacle. The two (2) charts below will assist you in selecting the proper combination
of elbow angle and chimney length(s) that will provide the necessary degree of offset within an available height.
1. Select the column with the proper chimney
diameter of your system.
2. Determine the distance of the offset required
by dropping a plumb bob for an accurate mea-
surement. The offset is measured at the chim-
ney centre line as per the "A" measurement in
the diagram.
3. On the chart, find the predetermined distance
(under the "A" column) required for the 15o
elbow. For greater offset, use the 30ooffset
chart.
4. After finding the offset, look under column "B"
to find the specified height and appropiate "chim-
ney lengths" required in the left column.
NOTE:
•Sentinel CF chimney is limited to offsets not exceeding 30 degrees. Combining offsets for greater
angle is not permitted.
•Two pairs of (four) 15oor 30oelbows may be used per interior installation.
•Locking bands must be used at each joints. For added security on multiples lengths forming
an offset, fasten the joints using two (2) #6 x 1/2" stainless steel sheet metal screws through
the pre-punched holes in the locking bands (see diagram on the left).
•Never install an elbow in a joist area. Chimney sections must pass vertically through framed
joist areas.
•Elbow support will support 30 feet of chimney and the maximum length of chimney allowed
between elbows is 6 feet.
