VENTING
INSTALLATION

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.

NOTICE: Failure to follow these
instructions will void the warranty.

INSTALLATION PRECAUTIONS

Consult local building codes before begin­ning the installation. Only a qualified 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 DESA
International

• Installation other than as instructed by
these instructions

Your Vanguard stove with B-vent burner
system is approved for use with any listed
gas vent. A listed gas vent is a factory made
and listed system designed, and installed
exclusively for removing products of com­bustion, excess air, and dilution air resulting
from burning fuel gas. Metal vents, the most
common type of vent, employ double wall
construction enclosing an insulating air
space. This air space both helps keep flue
gases warm and reduce heat transferred to
nearby combustibles. This appliance is
equipped with a safety control system de­signed to protect against improper venting
of combustion products.

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.

WARNING: This gas 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.

TYPE B-VENT INSTALLATION
(Listed B-0 or Greater)

Before beginning installation be sure that the
overall height and gas vent size conform to
building code requirements. Gas vents ex­tending through pitched roofs can extend a
minimum height of at least 600 mm (2')
higher than any obstruction within 3m (10').
Gas vents extending through flat roofs are
required to extend at least 600 mm (2') above
the roof and at least 600 mm (2') higher than
any portion of the building or adjoining build­ing within 3m (10') of the gas vent.

• Venting instruction contained in this
manual may or may not appy to your
area. Consult your local authority for re­quirement in your area.

• Where the gas vent extends through ac­cessible spaces, it should be enclosed to
avoid personal contact and damage. En­closure walls should have a fire rating
equal to or greater than the floors through
which the gas vent passes except in single
or two-family dwellings.

• Situate the gas vent in the structure so
that it can be installed without cutting
joists, sills, plates, or major load bearing
partitions or members. It is also impor­tant to locate the base of the gas vent as
near as possible to the heating appliance.

• This burner system must be properly con­nected to a venting system. This burner
system is equipped with a vent safety
shutoff system.

• Use only vents labeled "FOR EXTE­RIOR USE" above the roofline.

• Consult the authority having jurisdiction to
select the correct gas vent diameter. Avoid
using a larger than necessary diameter .

INSTALLATION OF LISTED
B-1 VENT

WARNING: Installation should
only be made by qualified per­sons who are familiar with the
safety procedures required for
the installation of the product,
who are equipped with the proper
tools and testing instruments,
and who have achieved proper
certification of licensing. Instal­lations made by unqualified per­sons can result in the risk of in­jury or electrical shock which can
be serious or even fatal.

Figures 22 through 24 show other options
for the gas vent. When venting through a
side wall your vent pipe must have the
proper temperature rating (see Figure 24).
Manufacturer's clearances must also be
maintained. Consult the authority having
jurisdiction in your area regarding venting
through side wall.

Figure 24 - Venting Through a Side Wall

INSTALLING VENT SYSTEM
IN A CHASE

A chase is a vertical box-like structure built
to enclose venting that runs along the out­side of a building. A chase is not required for
such venting.

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.

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".

CHECKING VENT CAPACITY

Complete all gas piping, electrical, and vent
connections. After adjusting the burner sys­tem and lighting the main burners, allow a
couple of minutes for warm-up. Hold a
lighted match just under the rim of the draft
hood relief opening. Proper venting will
draw the flame toward or into the draft hood.
Improper venting, indicated by escape or
spillage of burned gas, will cause match to
flicker or go out. Smoke from a cigarette
will also be pulled into the draft hood if the
vent is drawing properly.
