codes. You must follow all local
building codes.
Note: Wheninstallinginachase,youshould
insulate the chase as you would the outside
walls of your home. This is especially im-
portant in cold climates. Minimum clear-
ance between vent pipes and combustible
materials such as insulation is 1".
Installing Vent System in a Chase
A chase is a vertical boxlike structure built
to enclose venting that runs along the out-
sideofabuilding.Achaseisnotrequiredfor
such venting.
WARNING:Neverrunthevent
pipedownwardasthismaycause
excessive temperatures which
could cause a fire.
You may use one or two 90°elbows in this
ventconfiguration.SeeHorizontalTermina-
tion Configurations on pages 13 and 14.
For Vertical Termination: Measure the dis-
tance from the burner system flue outlet to
the ceiling. Add the ceiling thickness, the
vertical rise in an attic or second story, and
allow for sufficient vent height above the
roofline.Youmayuseoneortwo90°elbows
in this vent configuration. See Vertical Ter-
minationConfigurationsonpages16and17.
Note: Youmayusetwo45°elbowsinplace
of a 90°elbow. You must follow rise to run
ratios when using 45°elbows.
For two-story applications, firestops are re-
quiredateachfloorlevel.Ifanoffsetisneeded
intheattic,additionalpipe and elbows will be
required (see Figure 31, page 15).
You may use a chase with a vent termina-
tion with exposed pipe on the exterior of
the house. See Installing Vent System in a
Chase, below.
Your Comfort Glow stove with direct-vent
burner system has been tested for a maxi-
mum 17" wall thickness when using a 60º
elbowdirectlyoff the backofthestove.The
maximum horizontal run is 20' with 8' ver-
tical rise (see Installation for Horizontal
Termination, pages 11 and 12). The maxi-
mum vertical run is 30' (see Installation for
Vertical Termination, pages 14 and 15).
It is very important that the venting system
maintain its balance between the combus-
tion air intake and the flue gas exhaust.
Certain limitations apply to vent configura-
tions and must be strictly followed.

INSTALLATION FOR
HORIZONTAL TERMINATION
1. Determine the route your horizontal
venting will take. Note: The location
of the horizontal vent termination on
theexterior wall mustmeetall local and
national building codes and must not
be easily blocked or obstructed.
Snorkel terminations are available for
terminations requiring a vertical rise on
the exterior of the building (see Figures
19 and 20). Snorkel kit SVKBK is also
available(see page 17).Followthesame
installationproceduresusedforstandard
horizontal terminations. Ifinstalling the
snorkel termination below grade (base-
ment applications), you must provide
proper drainage to prevent water from
entering the snorkel termination (see
Figure 20). Do not back fill around the
snorkel termination.
2. Rigid vent pipes and fittings have spe-
cial twist-lock connections. Assemble
the desired combination of pipe and el-
bows to the appliance adaptor with pipe
seamsorientedtowardsthe wall or floor.
Twist-lock Procedure: The female ends
of the pipes and fittings have four locking
lugs (indentations). These lugs will slide
straightintomatchingslotsonthemaleends
ofadjacent pipesandfittings. (Allconnec-
tions must be sealed with high tempera-
turesiliconesealantas specified inthe sec-
ond warning statement on page 10.) Push
thepipesectionstogetherandtwistonesec-
tion clockwise approximately one-quarter
turn until the sections are fully locked. See
Figure 21, page 12. Note: Horizontal runs
ofvent must besupportedevery threefeet.
Use wall straps for this purpose.

Flat Ceiling Installation
1. Cut a 10" square hole in the ceiling us-
ing the locating hole as a center point.
The opening should be framed to
10"x10" (254mm x 254mm) inside di-
mensions, as shown in Figure 22 on
page12 usingframing lumber thesame
size as the ceiling joists. If the area
above the ceiling is an insulated ceil-
ing or a room, nail firestop from the
top side. This prevents loose insulation
from falling into the required clearance
space.Otherwise, installfirestopbelow
the framed hole. The firestop should be
installed with no less than three nails
per side (see Figure 31, page 15).
2. Assemble the desired lengths of pipe
and elbows necessary to reach from the
burner system flue up through the
firestop. All connections must be
sealed with high temperature silicone
sealantas specifiedin the secondwarn-
ing statement on page 10. Be sure all
pipe and elbow connections are fully
twist-locked (see Figure 21, page 12).
1. Determine the route your vertical vent-
ing will take. If ceiling joists, roof
rafters, or other framing will obstruct
the venting system, consider an offset
(see Figure 30) to avoid cutting
loadbearing members. Note: Pay spe-
cial attention to these installation in-
structions for required clearances (air
space) to combustibles when passing
through ceilings, walls, roofs, enclo-
sures, attic rafters, etc. Do not pack
air spaces with insulation. Also note
maximum vertical rise of the venting
system and any maximum horizontal
offset limitations. Offsets must fall
within the parameters shown in Fig-
ure 18 on page 9.
2. Set the stove in desired location. Drop
a plumb line down from the ceiling to
the position of the burner system exit
flue. Mark the center point where the
vent will penetrate the ceiling. Drill a
small locating hole at this point.
Drop a plumb line from the inside of
the roof to the locating hole in the ceil-
ing. Mark the center point where the
vent will penetrate the roof. Drill a
small locating hole at this point.

3. Cut a hole in the roof using the locating
hole as a center point. (Cover any ex-
posed open vent pipes before cutting
hole in roof.) The 10"x10" hole must
be measured on the horizontal; actual
length may be larger depending on the
pitch of the roof. There must be a 1"
clearancefrom the ventpipe tocombus-
tible materials. Frame the opening as
shown in Figure 22 on page 12.
4. Connect a section of pipe and extend
up through the hole.
Note: If an offset is needed to avoid
obstructions,you mustsupport the vent
pipe every 3 feet. Use wall straps for
this purpose (see Figure 30, page 14).
Whenever possible, use 45°elbows in-
stead of 90°elbows. The 45°elbow of-
fers less restriction to the flow of the
flue gases and intake air.
5. Place the flashing over the pipe
section(s) extending through the roof.
Secure the base of the flashing to the
roof and framing with roofing nails.
Be sure roofing material overlaps the
top edge of the flashing as shown in
Figure 30, page 14. There must be a
1" clearance from the vent pipe to
combustible materials.
6. Continue to add pipe sections until the
height of the vent cap meets the mini-
mum building code requirements de-
scribed in Figure 18 on page 9. Note:
You must increase vent height for steep
roof pitches. Nearby trees, adjoining
rooflines, steep pitched roofs, and other
similar factors may cause poor draft or
down-drafting in high winds. Increasing
the vent height may solve this problem.
7. Twist-lock the vent cap onto the last
section of vent pipe and seal outer pipe
connection with high temperature sili-
cone sealant as specified in the second
warning statement on page 10.
Note: If the vent pipe passes through any
occupiedareasabovethefirst floor, including
storage spaces and closets, you must enclose
pipe.Youmayframeandsheetrocktheenclo-
surewithstandardconstructionmaterial.Make
sure and meet the minimum allowable clear-
ances to combustibles. Do not fill any of the
required air spaces with insulation.
Cathedral Ceiling Installation
1. Remove shingles or other roof cover-
ing as necessary to cut the rectangular
hole for the support box. Mark the out-
lineof thecathedral ceilingsupportbox
on the roof sheathing using the locat-
ing hole as a center point.
2. Cut the hole 1/8" larger than the sup-
port box outline (see Figure 32).
3. Lower the supportbox through thehole
in the roof until the bottom of the box
extends at least 2" below the ceiling
(see Figure 32). Align the support box
verticallyand horizontally usinga level.
Temporarily tack the support box in
place through the inside walls and into
the roof sheathing.
4. Using tin snips,cut the supportboxfrom
the top corners down to the roofline and
fold the resulting flaps over the roof
sheathing (see Figure 33).Apply a bead
of non-hardening mastic around the top
edges of the support box to make a seal
between the box and the roof. Nail in
place with roofing nails. Remove any
combustible material that might be in-
side of the support box.
5. Complete the cathedral ceiling installa-
tion by following the same procedures
outlined in steps 2 through 7 for Flat
