VENTING
INSTALLATION
INSTALLATION PRECAUTIONS
Consult local building codes before
beginning the installation. The installer
must make sure to select the proper vent
system for installation. Before installing
vent kit, the installer must read this stove
and burner system manual and vent kit
instructions.
Only a qualified installer/service person
should install venting system. The
installer must follow these safety rules:
• Wear gloves and safety glasses for
protection
• Use extreme caution when using
ladders or when on roof tops
• Be aware of electrical wiring
locations in walls and ceilings
The following actions will void the
warranty on your venting system:
• Installation of any damaged venting
component
• Unauthorized modification of the
venting system
• Installation of any component part
not manufactured or approved by
Buck Stove
• Installation other than as instructed
by these instructions
INSTALLATION PLANNING
There are two basic types of direct-vent
installation:
• Horizontal Termination
• Vertical Termination
It is important to select the proper length
of vent pipe for the type of termination
you choose. It is also important to note
the wall thickness.
For Horizontal Termination: Select the
amount of vertical rise desired. The
horizontal run of venting must have ¼"
rise for every 12" of run towards the
termination.
You may use one 90° elbow in this vent
con fig uration . See Horizontal
Termination Configurations on page 15.
For Vertical Termination: Measure the
distance 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. You may
use one 90° elbow in this vent
configuration.
Note: When using Simpson Duravent
pipe, you must order the vertical restrictor
(shown in Figures 38 through 41 on pages
18 and 19) separately.
Note: You may use two 45° elbows in
place of a 90° elbow. You must follow rise
to run ratios when using 45° elbows.
For two-story applications, firestops are
required at each floor level. If an offset is
needed in the attic, additional pipe and
elbows will be required.
You may use a chase with a vent
termination with exposed pipe on the
exterior of the house. See Installing Vent
System in a Chase, below.
It is very important that the venting system
maintain its balance between the
combustion air intake and the flue gas
exhaust. Certain limitations apply to vent
configurations and must be strictly
followed.
Installing Vent System in a Chase
A chase is a vertical boxlike structure built
to enclose venting that runs along the
outside of a building. A chase is required
for such venting.
Note: When installing in a chase, you
should insulate the chase as you would the
outside walls of your home. This is
especially important in cold climates.
Minimum clearance between vent pipes
and combustible materials such as
insulation is 1".
WARNING: Read all instructions
completely and thoroughly before
attempting installation. Failure to
do so could result in serious injury,
property damage or loss of life.
Operation of improperly installed
and maintained venting system
could result in serious injury,
property damage or loss of life.
WARNING: For direct vent
designs, proper reassembly and
resealing of the vent-air intake
system. (see figure 20) Seal all vent
connections. Seal only the outer pipe
connections with high temperature
silicone (600°F/316°C). Before
joining elbows and pipes, apply a
bead of high temperature silicone
sealant (GERTV 106/Locktite
RTV81585) to the male end of the
elbow or pipe. High temperature
silicone must be used to re-seal any
connections after maintenance to
venting system.
NOTICE: Failure to follow these
instructions will void the warranty.
WARNING: This stove with burner
system and vent assembly must be
vented directly to the outside. The
venting system must NEVER be
attached to a chimney serving a
separate solid fuel burning
appliance. Each gas appliance must
use a separate vent system. Do not
use common vent systems.
WARNING: Horizontal sections
of this vent system require a
minimum clearance of 2" from the
top of the pipe and 1" minimum to
the sides and bottom. Vertical
sections of this system require a
minimum of 1" clearance to
combustible materials on all sides
of the pipe.
WARNING: Never run the vent pipe
downward as this may cause excess-
ive temperatures which could cause a
fire.
NOTICE: Treatment of firestops and
construction of the chase may vary
from building type to building type.
These instructions are not substitutes
for the requirements of local building
codes. You must follow all local
building codes.
