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.

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".
CHIMNEYS
• Complete familiarity with chimney condition, height, size, clearance to combustibles and other factors is essential.
NOTICE: Consult the authority
having jurisdiction in your area
regarding masonry chimney venting applications.
NOTICE: A complete chimney
inspection by a qualified person
should be performed.
• Appliances using B-vent connectors to
vent into a masonry or factory-built
chimney should not exceed 1 1/2 feet in
length for every inch of connector diameter (3" vent connector has a maximum
4 1/2 foot length; 5" connector has maximum 7 1/2 foot length).
• Oversized chimneys should be relined
with appropriate listed relining systems.
• Cleanout access may be required.
RELINING SYSTEMS
• Suitability and approval of relining materials should be determined.
• Condition, size, height, and termination
of the chimney to be relined must be determined.
• No substitution of components should be
made.
• Joints and connectors should be made
according to manufacturer’ s instructions.
NOTICE: Consult the authority
having jurisdiction in your area
regarding listed chimney liner
venting applications.
WARNING: Operation of improperly installed and maintained
venting system could result in
serious injury, property damage,
or loss of life.
CHECKING VENT CAPACITY
Complete all gas piping, electrical, and vent
connections. After adjusting the fireplace
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.

HIGH ALTITUDE
INSTALLATION
Your Vanguard B-vent freestanding fireplace
heater has been AGA tested and approved for
elevations from 0-2000 feet and CGA certified for elevations from 0-4500 feet.
When installing this fireplace at an elevation above 2000 feet (in the USA), you may
need to decrease the input rating by changing the existing burner orifice to a smaller
size. Reduce input 4% for each 1000 feet
above sea level. Check with your local gas
company for proper orifice size identification and proper orifice for your location.
When installing this fireplace at an elevation above 4500 feet (in Canada), check
with local authorities.
For assistance with any high altitude installation contact DESA International’s Technical Service Department at 1-800-DESALOG (1-800-337-2564).
TROUBLESHOOTING
VENTING
PROBLEMS
Most venting problems are caused by incorrect vent sizing, improper installation, or
inadequate air supply. A preliminary check
for a field problem might include:
• Using a draft meter to determine if venting system draft meets manufacturer’s
specifications
• Checking the vent sizing according to
manufacturer’s specif ications, appliance
input, and venting configuration
• Examining the entire venting system for
faults such as disconnected joints for
damaged vent sections
• Making sure vent and air openings are
not obstructed
If these procedures do not reveal the source of
the problem, troubleshooting may include
attention to common venting problems.
FLUE GAS SPILLAGE
Spillage occurs when flue gases cannot exit
the vent system and back up into the dwelling. A primary symptom of appliances
equipped with a Vent Safety Shutoff System
(flue spill switch) is unexplained appliance
shutoffs. Other symptoms of flue gas spillage
at the draft hood include condensation on
walls and windows and/or noticeable odors.
Spillage may also result in the release of
carbon monoxide, a colorless, odorless, highly
toxic gas. A simple spillage test can be conducted if spillage is suspected. See Checking
Gas Connection, pages 13 and 14.
CAUSES OF SPILLAGE AND
CORRECTIVE ACTION
Incorrect Vent Sizing
If the vent is too small or too short, spillage
may occur. If the vent is too large, excessive
dilution air may cool flue gases and reduce
draft, causing spillage. The vent cap size
should also be checked. Check
manufacturer’s instructions, appliance input rating, and appropriate sizing tables.
Venting Condition
Loose joints can affect draft and cause spillage. “Mashed” vent sections and damaged
vent caps can restrict flow and cause spillage. Examine and replace as needed.
Obstructions
Small animals or birds may get into and
block the vent or draft hood outlet. Dust,
lint, and foreign objects may obstruct air
inlets. Remove obstructions and clean openings.
Lateral Run
Lengthy hoizontal or non-vertical runs cause
resistance to flow and may reduce draft
enough to cause spillage. The pitch of lateral runs can also be a problem; lateral runs
should be pitched 1/4" rise per foot of horizontal run from the appliance to the vent.
Elbows
Too many elbows cause excessive restriction of flow and may result in spillage.
Usually, two 90º turns can be tolerated in a
properly sized venting system. More than
two may cause problems and necessitate
changing the system.
Negative Pressure in the
Dwelling
An extremely tight house may not supply
adequate combustion and venting air. Use
of mechanical exhaust such as a dryer vent
or range vent may worsen the problem. An
air exchange system must be installed in the
dwelling to correct this problem.
Flue Gas Cooling
Venting exposed to extremely cold temperatures or venting of single wall construction loses heat needed to maintain draft;
massive masonry chimneys absorb needed
heat. If the flue gases cool excessively, draft
is reduced and spillage may result. Use
proper materials, insulate and protect properly, reline when necessary.
Down Drafts
In certain wind conditions and in certain
relationships with nearby structures and
objects, high pressure conditions may affect
draft negatively. Relocate the vent cap, raise
its height, or use an approved high wind cap.

NOTICE: This heater is intended
for use as supplemental heat. Use
this heater along with your primary heating system. Do not install this heater as your primary
heat source. If you have a central
heating system, you may run
system’s circulating blower while
using heater. This will help circulate the heat throughout the
house. In the event of a power
outage, you can use this heater
as your primary heat source.
CHECK GAS TYPE
Use proper gas type for the fireplace unit
you are installing. If you have conflicting
gas types, do not install fireplace. See dealer
where you purchased the fireplace for proper
fireplace according to your gas type.
INSTALLING GAS PIPING TO
FIREPLACE LOCATION
WARNING: A qualified service person must connect fireplace to gas supply. Follow all
local codes.
CAUTION: For propane/LP
units, never connect heater directly to the propane/LP supply.
This heater requires an external
regulator (not supplied). Install the
external regulator between the
heater and propane/LP supply.
Installation Items Needed
Before installing fireplace, make sure you
have the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• manual shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas connector (if allowed by local codes) (not
provided)
* An A.G.A. design-certified manual shutoff
valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Purchase the A.G.A. design-certified manual
shutoff valve from your dealer.
For propane/LP connections only, the installer must supply an external regulator.
The external regulator will reduce incoming
gas pressure. You must reduce incoming
gas pressure to between 11 and 14 inches of
water. If you do not reduce incoming gas
pressure, heater regulator damage could
occur. Install external regulator with the
vent pointing down as shown in Figure 25.
Pointing the vent down protects it from
freezing rain or sleet.
CAUTION: Use only new,
black iron or steel pipe. Internally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of 1/2"
diameter or greater to allow
proper gas volume to fireplace. If
pipe is too small, undue loss of
pressure will occur.
Installation must include a manual shutoff
valve, union, and plugged 1/8" NPT tap.
Locate NPT tap within reach for test gauge
hook up. NPT tap must be upstream from
fireplace (see Figure 26, page 13).
Check your building codes for any special
requirements for locating manual shutoff
valve to fireplaces.
Apply pipe joint sealant lightly to male
threads. This will prevent excess sealant
from going into pipe. Excess sealant in pipe
could result in clogged fireplace valves.
CAUTION: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.
Install sediment trap/drip leg in supply line
as shown in Figure 26, page 13. Locate
sediment trap/drip leg where it is within
reach for cleaning. Locate sediment trap/
drip leg where trapped matter is not likely to
freeze. A sediment trap traps moisture and
contaminants. This keeps them from going
into fireplace gas controls. If sediment trap/
drip leg is not installed or is installed wrong,
fireplace may not run properly.

WARNING: Do not use abrasive cleaners as this may damage
glass. Use a non-abrasive household glass cleaner to clean glass.
Do not clean glass when hot.
Glass must be cleaned periodically. During
start-up it is normal for condensation to
form on the inside of the glass causing lint,
dust, and other airborne particles to cling to
the glass surface. During initial start-up a
slight film may form on the glass due to
paint curing. The glass should be cleaned
several times with a non-amonia, non-abrasive household cleaner and warm water
after the first two weeks of operation. Thereafter, clean the glass two or three times
during each heating season, depending on
the usage and circumstances present. Refer

PILOT AND BURNERS
• Remove ember material before cleaning
burners and replace when cleaning is
complete.
• Burner and controls should be cleaned
with compressed air to remove dust, dirt,
or lint.
• Use a vacuum cleaner or small, soft
bristled brush to remove excess dust, dirt,
or lint.
LOGS
• If you remove logs for cleaning, refer to
Installing Logs, Lava Rock, and Glowing
Embers, page 17, to properly replace logs.
• Use a vacuum cleaner to remove an y carbon build-up on logs.
• Replace log(s) if broken. See Replace-
ment Parts on page 25.
• Replace ember material periodically as
needed. See Replacement P arts on page 25.
VENTING SYSTEM
Conduct annual inspection of the venting
system following these guidelines:
1. Check areas of venting system that are
exposed to the weather for corrosion (rust
spots or streaks and, in extreme cases,
holes). Have these items replaced immediately by a qualified service person.
2. Remove the vent cap and shine a flash-
light into the vent. Remove any foreign
material.
3. Check for evidence of excessive con-
densation. Continuous condensation
can cause corrosion of caps, pipes, and
fittings and can be caused by having
excessive lateral runs, too many elbows, or exterior portions of the system being exposed to cold weather.
4. Inspect joints to verify that no pipe sec-
tion or fitting has been disturbed and
loosened. Check mechanical supports
such as wall straps for rigidity.

DESA INTERNATIONAL SHALL NOT BE LIABLE FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT,

damages, so the above limitation on implied warranties, or exclusion or limitation on damages may not apply to you.
