higher comfort settings allows fireplace to run longer, producing  
greater heat output. At lower comfort settings, the fireplace will run  
less. This results in increased heating comfort. This can also result  
in lower gas bills.  
WARNING: Do not remove the data plates at-  
tached to the heater base assembly. The data plates  
contain important warranty and safety information.

WARNING: This heater shall not be installed in a  
confined space or unusually tight construction un-  
less provisions are provided for adequate combus-  
tion and ventilation air. Read the following instruc-  
tions to insure proper fresh air for this and other  
fuel-burning appliances in your home.  
PRODUCT FEATURES  
OPERATION  
This vent-free fireplace is clean burning. It requires no outside  
venting. There is no heat loss out a vent or up a chimney. Heat is  
generated by both realistic flames and glowing embers. When used  
without the blower, the fireplace requires no electricity making it  
ideal for emergency backup heat.  
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.  
SAFETY DEVICE  
This fireplace 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 system shuts off the fireplace if there  
is not enough fresh air.  
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.  
Exhaustfans,fireplaces,clothesdryers,andfuelburningappliances

air for these appliances. This will insure proper venting of vented  
fuel-burning appliances.  
PIEZO IGNITION SYSTEM  
This fireplace has a piezo ignitor. This system requires no matches,  
batteries, or other sources to light fireplace.  
BLOWER ASSEMBLY  
(VSGF28NTC)  
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.  
This fireplace has a blower assembly. The blower operates thermo-  
statically and has a variable speed control. The blower circulates  
heated air from the fireplace into the room. Use of blower is optional.  
Optional blower accessories are available for model VSGF28NVA.  
See Accessories, page 22.  
All spaces in homes fall into one of the three following ventilation  
classifications:  
1. Unusually Tight Construction  
2. Unconfined Space  
3. Confined Space  
The information on pages 4 through 6 will help you classify your  
space and provide adequate ventilation.

AIR FOR COMBUSTION AND  
VENTILATION  
Continued  
Example: Space size 22 ft. (length) x 18 ft. (width) x 8 ft. (ceiling  
height) = 3168 cu. ft. (volume of space)  
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.  
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.  
Unusually tight construction is defined as construction  
where:  
__________ (volume of space) x 20 = (Maximum Btu/Hr the space  
can support)  
a. walls and ceilings exposed to the outside atmosphere  
have a continuous water vapor retarder with a rating  
of one perm (6 x 10-11 kg per pa-sec-m2) or less with  
openings gasketed or sealed and  
Example: 3,168 cu. ft. (volume of space) x 20 = 63,360 (maximum  
Btu/Hr the space can support)  
3. Add the Btu/Hr of all fuel burning appliances in the space.

4. Compare the maximum Btu/Hr the space can support with the actual  
amount of Btu/Hr used.  
The National Fuel Gas Code, ANSI Z223.1/NFPA 54 defines a  
confined space as a space whose volume is less than 50 cubic feet  
per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating  
of all appliances installed in that space and an unconfined space as  
aspacewhosevolumeisnotlessthan50cubicfeetper1,000Btuper  
hour (4.8 m3 per kw) of the aggregate input rating of all appliances  
installed in that space. Rooms communicating directly with the  
space in which the appliances are installed*, through openings not  
furnished with doors, are considered a part of the unconfined space.  
__________________ Btu/Hr (maximum the space can support)  
__________________ Btu/Hr (actual amount of Btu/Hr used)  
Example: 63,360 Btu/Hr (maximum the space can support)  
68,000 Btu/Hr (actual amount of Btu/Hr used)  
The space in the example on page 5 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.

near top of screen. Discard screws. Lift fireplace screen up  
and pull out to remove.  
IMPORTANT: Install equipment shutoff valve in an accessible  
location. The equipment shutoff valve is for turning on or shutting  
off the gas to the appliance.  
2. Remove screws that attach log base assembly to fireplace (see  
Figure 18). Carefully lift up log base assembly and remove  
from fireplace (see Figure 18).  
Checkyourbuildingcodesforanyspecialrequirementsforlocating  
equipment shutoff valve to fireplaces.  
Note: If adding the G8000 series brick liner accessory, install it  
now. Follow instructions in G8000 accessory kit.  
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 fireplace valves. Never use thread sealant on flare threads.  
CAUTION: Do not pick up log base assembly by  
burners. This could damage burners. Only handle  
base by grates.  
CAUTION: Use pipe joint sealant that is resistant  
to liquid petroleum (LP) gas.

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  
VENT-FREE NATURAL GAS FIREPLACE  
DESA International warrants this product to be free from defects in materials and components for four (4) years and five (5) years on stainless steel burners  
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 DURATION OF ANY AND  
ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE  
TO FOUR (4) YEARS ON ALL COMPONENTS AND FIVE (5) YEARS ON STAINLESS STEEL BURNERS 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, INCIDEN-  
TAL 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.
