Today’s homes are built more energy efficient than ever. New  
materials, increased insulation, and new construction methods help  
reduce heat loss in homes. Home owners weather strip and caulk  
around windows and doors to keep the cold air out and the warm air  
in. During heating months, home owners want their homes as airtight  
as possible.  
Quincy, MA 02269  
Note: Where listed vented decorative logs are required, thermo-  
stat operation is not permitted.  
UNPACKING  
While it is good to make your home energy efficient, your home  
needs to breathe. Fresh air must enter your home. All fuel-burning  
appliances need fresh air for proper combustion and ventilation.  
CAUTION: Do not remove the data plates from the  
grate assembly. The data plates contain important  
product information.  
Exhaustfans,fireplaces,clothesdryers,andfuelburningappliances  
drawairfromthehousetooperate.Youmustprovideadequatefresh  
air for these appliances. This will insure proper venting of vented  
fuel-burning appliances.  
1. Remove logs and heater base assembly from carton. Note: Do  
not pick up heater base assembly by burners. This could dam-  
age heater. Always handle base assembly by grate.  
2. Remove all protective packaging applied to logs and heater  
for shipment.  
PROVIDING ADEQUATE VENTILATION  
The following are excerpts from National Fuel Gas Code, ANSI  
Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation.  
3. Check all items for any shipping damage. If damaged, promptly  
inform dealer where you bought heater.  
All spaces in homes fall into one of the three following ventilation  
classifications:  
PRODUCT FEATURES  
OPERATION  
1. Unusually Tight Construction  
2. Unconfined Space  
This heater is clean burning. It requires no outside venting. There is  
no heat loss out a vent or up a chimney. Heat is generated by realistic  
dancing, yellow flames. This heater is designed for vent-free opera-  
tion with flue damper closed. It has been tested and approved to  
ANSI Z21.11.2 standard for unvented heaters. State and local codes  
in some areas prohibit the use of vent-free heaters. This heater may  
also be operated as a vented decorative (ANSI Z21.60) product by  
opening the flue damper (non-thermostat operation only).  
3. Confined Space  
The information on pages 4 through 6 will help you classify your  
space and provide adequate ventilation.  
Unusually Tight Construction  
The air that leaks around doors and windows may provide enough  
fresh air for combustion and ventilation. However, in buildings of  
unusually tight construction, you must provide additional fresh air.  
SAFETY PILOT  
Unusually tight construction is defined as construction  
where:  
This heater has a pilot with an Oxygen Depletion Sensing (ODS)  
safety shutoff system. The ODS/pilot is a required feature for vent-  
free room heaters. The ODS/pilot shuts off the heater if there is not  
enough fresh air.  
a. walls and ceilings exposed to the outside atmosphere  
have a continuous water vapor retarder with a rating  
of one perm (6x10-11 kg per pa-sec-m2) or less with  
openings gasketed or sealed and

The space in the above example is a confined space because the actual Btu/  
Hr used is more than the maximum Btu/Hr the space can support. You must  
provide additional fresh air. Your options are as follows:  
* Adjoining rooms are communicating only if there are doorless  
passageways or ventilation grills between them.  
A. Rework worksheet, adding the space of an adjoining room. If the  
extra space provides an unconfined space, remove door to adjoining  
room or add ventilation grills between rooms. See Ventilation Air From  
Inside Building, page 6.

tion 5.3 or applicable local codes.  
Example: Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling  
height) = 2560 cu. ft. (volume of space)  
If additional ventilation to adjoining room is supplied with grills or open-  
ings, add the volume of these rooms to the total volume of the space.  
2. Multiply the space volume by 20 to determine the maximum Btu/Hr  
the space can support.  
__________ (volume of space) x 20 = (Maximum Btu/Hr the space

INSTALLATION  
NOTICE: This heater is intended for use as supple-  
mental 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 log heater. This will help circulate the  
heat from your log heater throughout the house. In  
the event of a power outage, you can use this heater  
as your primary heat source.  
CAUTION: This heater creates warm air currents.  
These currents move heat to wall surfaces next to  
heater. Installing heater next to vinyl or cloth wall  
coveringsoroperatingheaterwhereimpurities(such  
as, but not limited to, tobacco smoke, aromatic  
candles, cleaning fluids, oil or kerosene lamps, etc.)  
in the air exist, may discolor walls or cause odors.  
IMPORTANT: Vent-free heaters add moisture to the air. Although  
this is beneficial, installing heater in rooms without enough venti-  
lation air may cause mildew to form from too much moisture. See  
Air for Combustion and Ventilation, pages 4 through 6.  
WARNING: A qualified service person must in-  
stall heater. Follow all local codes.  
CHECK GAS TYPE  
NOTICE: State or local codes may only allow opera-  
tionofthisapplianceinaventedconfiguration.Check  
your state or local codes.

you bought heater for proper type heater.  
INSTALLATION AND CLEARANCES  
(Vent-Free Operation Only)  
WARNING: Before installing in a solid fuel burn-  
ing fireplace, the chimney flue and firebox must be  
cleaned of soot, creosote, ashes, and loose paint by  
a qualified chimney cleaner. Creosote will ignite if  
highly heated. A dirty chimney flue may create and  
distribute soot within house. Inspect chimney flue  
and firebox for damage. If damaged, repair flue be-  
fore operating heater.

INSTALLING HEATER BASE ASSEMBLY  
INSTALLING DAMPER CLAMP ACCESSORY  
FOR VENTED OPERATION  
CAUTION:Donotremovethedataplatesattached  
to the heater base assembly. The data plates contain  
important warranty and safety information.  
Note: When used as a vented heater, appliance must be installed  
only in a solid-fuel burning fireplace with a working flue and  
constructed of noncombustible material.  
If your heater is a manually controlled model, you may use this  
heater as a vented product. There are three reasons for operating  
your heater in the vented mode.  
WARNING: You must secure this heater to fire-  
place floor. If not, heater will move when you adjust  
controls. Moving heater may cause a gas leak.  
1. The fireplace does not meet the clearance to combustibles re-  
quirements for vent-free operation.  
2. State or local codes do not permit vent-free operation.  
3. You prefer vented operation.  
WARNING:Ifinstallinginasunkenfireplace,special  
care is needed. You must raise the fireplace floor to  
allow access to heater control panel. This will insure  
adequate air flow and guard against sooting and con-  
trols being damaged. Raise fireplace floor with non-  
combustible material. Make sure material is secure.  
If reasons number 1 or 2 above apply to you, you must permanently  
open chimney flue damper. You must install the damper clamp  
accessory(toorder,seeAccessories,page26).Thiswillinsurevented  
operation (see Figure 11). The damper clamp will keep damper open.  
Installation instructions are included with clamp accessory.  
CAUTION: Do not pick up heater base assembly  
bytheburner.Thiscoulddamageheater.Onlyhandle  
base assembly by grates.  
See chart below for minimum permanent flue opening you must  
provide. Attach damper clamp so the minimum permanent flue  
opening will be maintained at all times.

IMPORTANT: Make sure the heater burners are level. If heater is  
not level, heater will not work properly. For thermostat models,  
avoid damage to thermostat bulb. Avoid nicks or sharp bends in  
thermostat bulb wire. Keep thermostat bulb in mounting bracket  
until ready to mount base to floor. See Optional Positioning Of

• piping (check local codes)  
• sealant (resistant to propane/LP gas)  
• equipment shutoff valve *  
• test gauge connection *  
• sediment trap

* A CSA design-certified equipment shutoff valve with 1/8" NPT  
tap is an acceptable alternative to test gauge connection. Purchase  
the optional CSA design-certified equipment shutoff valve from  
your dealer. See Accessories, page 26.  
For propane/LP units, theinstallermustsupplyanexternalregulator.  
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 15, page 12. Pointing the vent down protects it from  
freezing rain or sleet.

INSTALLATION  
Continued  
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 heater (see Figure 16).  
WARNING: Use pipe joint sealant that is resistant  
to liquid petroleum (LP) gas.  
IMPORTANT: Install equipment valve in an accessible location.  
The equipment shutoff valve is for turning on or shutting off the gas  
to the appliance.  
We recommend that you install a sediment trap in supply line as  
showninFigure16.Locatesedimenttrapwhereitiswithinreachfor  
cleaning. Install in piping system between fuel supply and heater.  
Locate sediment trap where trapped matter is not likely to freeze. A  
sediment trap traps moisture and contaminants. This keeps them  
from going into heater controls. If sediment trap is not installed or  
is installed wrong, heater may not run properly.  
Checkyourbuildingcodesforanyspecialrequirementsforlocating  
equipment shutoff valve to fireplaces.  
Apply pipe joint sealant lightly to male NPT threads. This will  
prevent excess sealant from going into pipe. Excess sealant in pipe  
could result in clogged heater valves.  
CAUTION: Avoid damage to regulator. Hold gas  
regulator with wrench when connecting it to gas  
piping and/or fittings.

excessive. You can open the chimney damper (if you have one)  
fully or partially to release some of the heat.  
B. BEFORE LIGHTING smell all around the appliance area  
for gas. Be sure to smell next to the floor because some gas  
is heavier than air and will settle on the floor.  
WARNING: Damper handle will be hot if heater  
has been running.  
WHAT TO DO IF YOU SMELL GAS  
• Do not try to light any appliance.  
• Do not touch any electric switch; do not use any phone in  
your building.  
• Immediately call your gas supplier from a neighbor’s  
phone. Follow the gas supplier’s instructions.

4. Wait five (5) minutes to clear out any gas. Then smell for  
gas, including near the floor. If you smell gas, STOP! Fol-  
low “B” in the safety information, column 1. If you don’t  
smell gas, go to the next step.  
C. Use only your hand to push in or turn the gas control knob.  
Never use tools. If the knob will not push in or turn by  
hand, don’t try to repair it, call a qualified service techni-  
cian or gas supplier. Force or attempted repair may result  
in a fire or explosion.  
5. Turn control knob counterclockwise

the appliance and to replace any part of the control system  
and any gas control which has been under water.  
Note: You may be running this heater for the first time  
after hooking up to gas supply. If so, the control knob may  
need to be pressed in for 30 seconds or more. This will al-  
low air to bleed from the gas system.

4. Check the injector holder located at the end of the burner tube  
again. Remove any large particles of dust, dirt, lint, or pet hair  
with a soft cloth or vacuum cleaner nozzle.  
BURNER PRIMARY AIR HOLES  
Air is drawn into the burner through the holes in the fitting at the  
entrance to the burner. These holes may become blocked with dust,  
lint, or pet hair. Periodically inspect these holes for any blockage and  
clean as necessary. Blocked air holes will create soot.  
5. Blow air into the primary air holes on the injector holder.  
6. In case any large clumps of dust have now been pushed into  
the burner repeat steps 3 and 4.  
MAIN BURNER  
Clean the pilot assembly also. A yellow tip on the pilot flame  
indicates dust and dirt in the pilot assembly. There is a small pilot  
air inlet hole about two inches from where the pilot flame comes out  
of the pilot assembly (see Figure 42). With the unit off, lightly blow

The primary air inlet holes allow the proper amount of air to mix with  
the gas. This provides a clean burning flame. Keep these holes clear  
of dust, dirt, lint, and pet hair. Clean these air inlet holes prior to each  
heating season. Blocked air holes will create soot. We recommend  
that you clean the unit every three months during operation and have  
heater inspected yearly by a qualified service person.

We also recommend that you keep the burner tube and pilot  
assembly clean and free of dust and dirt. To clean these parts we  
recommendusingcompressedairnogreaterthan30PSI. Yourlocal  
computer store, hardware store, or home center may carry com-  
pressed air in a can. You can use a vacuum cleaner in the blow  
position. If using compressed air in a can, please follow the direc-  
tions on the can. If you don't follow directions on the can, you could  
damage the pilot assembly.  
• If you remove logs for cleaning, refer to Installing Logs, pages  
13 through 17, to properly replace logs.  
• Replace log(s) if broken or chipped (dime-sized or larger).

1. Shut off the unit, including the pilot. Allow the unit to cool for  
at least thirty minutes.  
2. Inspect burner, pilot, and primary air inlet holes on injector  
holder for dust and dirt (see Figure 41).

WARRANTY INFORMATION  
KEEP THIS WARRANTY  
Model  
Serial No.

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  
COMFORT GLOW VENT-FREE GAS LOG HEATERS  
DESA warrants this product to be free from defects in materials and components for two (2) 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.  
Thiswarrantyisextendedonlytotheoriginalretailpurchaser.Thiswarrantycoversthecostofpart(s)requiredtorestorethisheatertoproperoperating  
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 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 DURATION OF ANY AND  
ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE  
TO TWO (2) YEARS ON ALL COMPONENTS FROM THE DATE OF FIRST PURCHASE; AND DESA’S LIABILITY IS HEREBY LIMITED  
TO THE PURCHASE PRICE OF THE PRODUCT AND DESA 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.
