Figures 24, 25 and 26, show other options  
for the gas vent. When venting through a  
side wall your vent pipe must have the  
proper temperature rating (see Figure 26).  
Manufacturer’s clearances must also be  
maintained. Consult the authority having  
jurisdiction in your area regarding venting  
through side wall.  
CHECKING VENT CAPACITY  
Complete all gas piping, electrical, and vent  
connections. After adjusting the fireplace  
andlightingthemainburners,allowacouple  
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. Im-  
proper venting, indicated by escape or spill-  
age 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.

Venting Condition  
TROUBLESHOOTING  
VENTING  
STOVE AND B-VENT  
Loose joints can affect draft and cause spill-  
age. “Mashed” vent sections and damaged  
vent caps can restrict flow and cause spill-  
age. Examine and replace as needed.  
BURNER SYSTEM  
INSTALLATION  
PROBLEMS  
Most venting problems are caused by incor-  
rect vent sizing, improper installation, or  
inadequate air supply. A preliminary check  
for a field problem might include:  
NOTICE: This heater is intended  
foruseassupplementalheat.Use  
this heater along with your pri-  
mary heating system. Do not in-  
stall this heater as your primary  
heat source. If you have a central  
heating system, you may run  
systemscirculatingblowerwhile  
using heater. This will help circu-  
late the heat throughout the  
house. In the event of a power  
outage, you can use this heater  
as your primary heat source.  
Obstructions  
Smallanimalsorbirdsmaygetintoandblock  
the vent or draft hood outlet. Dust, lint, and  
foreign objects may obstruct air inlets. Re-  
move obstructions and clean openings.  
• Using a draft meter to determine if  
venting system draft meets  
manufacturer’s specifications  
Lateral Run  
• Checking the vent sizing according to  
manufacturer’s specifications, appliance  
input, and venting configuration  
Lengthyhorizontalornon-verticalrunscause  
resistance to flow and may reduce draft  
• Examining the entire venting system for enough to cause spillage. The pitch of lateral  
faults such as disconnected joints for runs can also be a problem; lateral runs  
damaged vent sections  
should be pitched 1/4" rise per foot of hori-  
zontal run from the appliance to the vent.  
• Making sure vent and air openings are  
not obstructed  
CHECK GAS TYPE  
Elbows  
Use proper gas type for the burner system  
unit you are installing. If you have conflict-  
ing gas types, do not install burner system.  
See dealer where you purchased the burner  
system for proper system according to your  
gas type.  
Iftheseproceduresdonotrevealthesourceof  
the problem, troubleshooting may include  
attention to common venting problems.  
Too many elbows cause excessive restric-  
tion 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.  
FLUE GAS SPILLAGE  
Spillage occurs when flue gases cannot exit  
the vent system and back up into the dwell-  
ing. A primary symptom of appliances  
equipped with a Vent Safety Shutoff System  
(flue spill switch) is unexplained appliance  
shutoffs.Othersymptomsoffluegasspillage  
at the draft hood include condensation on  
walls and windows and/or noticeable odors.  
Spillage may also result in the release of  
carbonmonoxide,acolorless,odorless,highly  
toxic gas. A simple spillage test can be con-  
ducted if spillage is suspected. See Checking  
Gas Connection, pages 14 and 15.  
INSTALLING GAS PIPING TO  
FIREPLACE LOCATION  
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.  
WARNING: A qualified in-  
staller or service person must  
connect burner system to gas  
supply. Follow all local codes.  
CAUTION: For propane/LP  
units, never connect heater di-  
rectly to the propane/LP supply.  
This heater requires an external  
regulator(notsupplied).Installthe  
external regulator between the  
heater and propane/LP supply.  
Flue Gas Cooling  
Venting exposed to extremely cold tem-  
peraturesorventingofsinglewallconstruc-  
tion loses heat needed to maintain draft;  
massive masonry chimneys absorb needed  
heat. Ifthefluegasescoolexcessively, draft  
is reduced and spillage may result. Use  
proper materials, insulate and protect prop-  
erly, reline when necessary.  
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 in-  
put rating, and appropriate sizing tables.

INSTALLATION  
We recommend that you install a sediment  
trap/drip leg in supply line as shown in  
Figure 31. Locate sediment trap/drip leg  
where it is within reach for cleaning. Install  
in piping system between fuel supply and  
heater. Locate sediment trap/drip leg where  
trapped matter is not likely to freeze. A  
sediment trap traps moisture and contami-  
nants. This keeps them from going into

Installation Items Needed  
Before installing stove and burner system,  
make sure you have the items listed below.  
• external regulator (supplied by installer)  
• piping (check local codes)  
• sealant (resistant to propane/LP gas)  
• equipment shutoff valve *  
• test gauge connection *  
• sediment trap  
Installation must include an equipment  
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 burner system (see Figure 31).  
Check your building codes for any special  
requirementsforlocatingequipmentshutoff  
valve to stove.  
• tee joint  
• pipe wrench  
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.  
• approved flexible gas line with gas con-  
nector (if allowed by local codes) (not  
provided)

OPERATING STOVE  
WITH B-VENT  
be allowed to stabilize at room tempera-  
ture for a minimum of 30 minutes for  
proper operation.  
Burner flames will be steady; not lifting or  
floating. Flame patterns will be different  
from unit to unit and will vary depending on  
installation type and weather conditions.  
BURNER SYSTEM  
To turn the burner system off, adjust  
thermostat to the lowest setting and turn  
the gas control knob back to PILOT. The  
pilot will remain lit.  
Continued  
If the vent configuration is installed incor-  
rectly, the flames will lift or “ghost”. This  
can be dangerous. Inspect the flames after  
installation to ensure proper installation  
and performance.

• see Troubleshooting, pages 23 through 25  
Light the fireplace as instructed in Light-  
ing Instructions on page 19. Set wall ther-  
mostat to desired temperature.  
PILOT ASSEMBLY  
The pilot assembly is factory preset for the  
proper flame height. Alterations may have  
occurredduringshippingandhandling.Call  
a qualified service person to readjust the  
pilot if necessary.  
This thermostat has been electronically  
calibrated at the factory and requires no  
adjustment or leveling.  
OPERATING  
OPTIONAL BLOWER  
ACCESSORY  
The height of the thermopile must be 3/8" to  
1/2" above the pilot flame as shown in  
Figure 54. The flame from the pilot burner  
must extend beyond the thermopile.  
Figure 55 - Typical Flame Pattern  
Blower controls are located on the left  
side of the rear cover of stove (from front  
of stove).  
If your pilot assembly does not meet these  
requirements:  
• turn burner system off (see To Turn Off  
Gas to Appliance, page 19)  
The DA3610TA thermostatically-con-  
trolled blower has an ON setting and an  
OFF setting. The blower will only run  
when the switch is in the ON position. In  
the OFF position, the blower will not  
operate.

If you are using DA3610TA blower with  
optional thermostat (wall mount or re-  
mote control), your burner system and  
blower will not turn on and off at the  
same time. The burner system may run  
for several minutes before the blower  
turns on. After the heater modulates to  
the pilot position, the blower will con-  
tinuetorun.Theblowerwillshutoffafter  
the burner system firebox temperature

The blower helps distribute heated air  
from the burner system. Periodically  
check the top grates of the stove and  
remove any dust, dirt, or other obstruc-  
tions that will hinder the flow of air.

MAINTENANCE  
Installing Logs, Lava Rock, and Glowing  
Embers, page 18, to properly replace logs.  
• Use a vacuum cleaner to remove any car-  
bon buildup on logs.  
WARNING:Turnoffburnersys-  
tem and let cool before cleaning.  
• Replace log(s) if broken. See Replace-  
ment Parts on page 26.  
CAUTION:Youmustkeepcon-  
trol areas, burners, and circulat-  
ing air passageways of stove and  
burner system clean. Inspect  
theseareasbeforeeachuse.Have  
burner system inspected yearly  
by a qualified service person.  
Stove and burner system may  
need more frequent cleaning due  
to excessive lint from carpeting,  
bedding material, pet hair, etc.  
• Replace ember material periodically as  
needed. See Replacement Parts on page 26.  
CAUTION: Wear gloves and  
safety glasses while handling or  
removing broken glass. Do not  
remove if glass is hot. Keep chil-  
dren and pets away from glass.  
VENTING SYSTEM  
Conduct annual inspection of the venting  
system following these guidelines:  
If glass has been broken, carefully remove  
glass door (see Removing/Replacing Glass  
Door, page 17). Vacuum all glass pieces  
with a shop vac.  
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 imme-  
diately by a qualified service person.  
GLASS DOOR  
CAUTION: Do not vacuum if  
pieces are hot.  
2. Remove the vent cap and shine a  
flashlight into the vent. Remove any  
foreign material.  
WARNING: Handle glass  
door panel with care. Do not  
strike, slam or otherwise abuse  
glass. Do not operate burner  
system with the glass door re-  
moved, cracked, or broken.  
Use only the ceramic glass door replace-  
ment intended for this burner system (see  
Replacement Parts, page 26, for details on  
ordering). No substitutions may be made.  
See Removing/Replacing Glass Door, page  
17, for instructions for replacing glass door.  
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 el-  
bows, or exterior portions of the sys-  
tem being exposed to cold weather.  
WARNING: Do not use abra-  
sivecleanersasthismaydamage  
glass. Use a nonabrasive house-  
hold glass cleaner to clean glass.  
Do not clean glass when hot.  
WARNING: Do not operate  
burnersystemwiththeglassdoor  
removed, cracked, or broken.  
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.  
PILOT AND BURNERS  
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-ammonia, non-  
abrasivehouseholdcleanerandwarmwater  
afterthefirsttwoweeksofoperation.There-  
after, clean the glass two or three times  
during each heating season, depending on  
the usage and circumstances present. Refer  
toRemoving/ReplacingGlassDooronpage  
17ofthismanualwhenremovingglassdoor  
for cleaning.  
• Remove ember material before clean-  
ing 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.

WARRANTY INFORMATION  
KEEP THIS WARRANTY  
Model  
Serial No.  
Date Purchased  
Always specify model and serial numbers when communicating with the factory.  
We reserve the right to amend these specifications at any time without notice. The only warranty applicable is our standard written  
warranty. We make no other warranty, expressed or implied.  
LIMITED WARRANTY  
B-VENT FREESTANDING FIREPLACE AND SUN VALLEY STOVE CHASSIS  
DESA International warrants this product to be free from defects in materials and components for four (4) years from the date of first  
purchase, provided that the product has been properly installed, operated and maintained in accordance with all applicable instructions.  
To make a claim under this warranty the Bill of Sale or cancelled check must be presented.  
This warranty is extended only to the original retail purchaser. This warranty covers the cost of part(s) required to restore this heater to  
proper operating condition and an allowance for labor when provided by a DESA Authorized Service Center. Warranty part(s) MUST  
be obtained through authorized dealers of this product and/or DESA International who will provide original factory replacement parts.  
Failure to use original factory replacement parts voids this warranty. The heater MUST be installed by a qualified installer in accordance  
with all local codes and instructions furnished with the unit.  
This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that fail or become  
damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by improper installation. Travel, diagnostic cost,  
labor, transportation and any and all such other costs related to repairing a defective heater will be the responsibility of the owner.  
TO THE FULL EXTENT ALLOWED BY THE LAW OF THE JURISDICTION THAT GOVERNS THE SALE OF THE PRODUCT;  
THIS EXPRESS WARRANTY EXCLUDES ANY AND ALL OTHER EXPRESSED WARRANTIES AND LIMITS THE DURA-  
TION OF ANY AND ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS  
FOR A PARTICULAR PURPOSE TO FOUR (4) YEARS ON ALL COMPONENTS FROM THE DATE OF FIRST PURCHASE;  
AND DESA INTERNATIONAL’S LIABILITY IS HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND  
DESA INTERNATIONAL SHALL NOT BE LIABLE FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT,  
INCIDENTAL OR CONSEQUENTIAL DAMAGES.  
Some states do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation of incidental or consequential  
damages, so the above limitation on implied warranties, or exclusion or limitation on damages may not apply to you.  
This warranty gives you specific legal rights, and you may also have other rights that vary from state to state.
