AIR FOR  
COMBUSTION  
AND  
WARNING  
WARNING ICON  
G
001  
This heater shall not be installed in a confined space unless  
provisions are provided for adequate combustion and ventilation  
air. Read the following instructions to insure proper fresh air for  
this and other fuel-burning appliances in your home.  
VENTILATION  
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.  
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.  
Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances draw air from  
the house to operate. You must provide adequate fresh air for these appliances.  
This will insure proper venting of vented fuel-burning appliances.  
PROVIDING ADEQUATE VENTILATION  
The following is exerpts from National Fuel Gas Code. NFPA 54/ANSI Z223.1,  
Section 5.3, Air for Combustion and Ventilation.  
All spaces in homes fall into one of the three following ventilation classifications:  
1. Unusually Tight Contruction; 2. Unconfined Space; 3. Confined Space.  
The information on pages 5 through 7 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.  
Unusually tight construction is defined as construction where:  
a. walls and ceilings exposed to the outside atmosphere have a continu-  
ous water vapor retarder with a rating of one perm or less with open-  
ings gasketed or sealed and  
b. weather stripping has been added on openable windows and doors and  
c. caulking or sealants are applied to areas such as joints around window  
and door frames, between sole plates and floors, between wall-ceiling  
joints, between wall panels, at penetrations for plumbing, electrical, and  
gas lines, and at other openings.  
If your home meets all of the three criteria above, you must provide addi-  
tional fresh air. See Ventilation Air From Outdoors, page 7.  
If your home does not meet all of the three criteria above, proceed to page 6.  
Unconfined Space  
The National Fuel Gas Code, ANSIZ223.1, 1992, Section 5.3 defines uncon-  
fined space as having a minimum air volume of 50 cubic feet (127 cubic cm) for  
each 1000 Btu/Hr input rating of all appliances in the space (cubic feet equals  
length x width x height of space). Include adjoining rooms only if there are  
doorless passageways or ventilation grills between the rooms.  
Confined Space  
The National Fuel Gas Code, ANSIZ223.1, 1992, Section 5.3 defines confined  
space as having an air volume of less than 50 cubic feet (127 cubic cm) for each  
1000 Btu/Hr input rating of all appliances in the space (cubic feet equals length  
x width x height of space). Include adjoining rooms only if there are doorless  
passageways or ventilation grills between the rooms.

DETERMINING AIR FLOW FOR HEATER LOCATION  
AIR FOR  
COMBUSTION  
AND  
Determining if You Have a Confined or Unconfined Space  
Use this work sheet to determine if you have a confined or unconfined space.  
Space: Includes the room in which you will install heater plus any adjoining rooms with  
doorless passageways or ventilation grills between the rooms.  
VENTILATION  
1. Determine the volume of the space (length x width x height).  
Continued  
Length x Width x Height =  
___________________  
cu. ft. (volume of space)  
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 openings, add the  
volume of these rooms to the total volume of the space.  
2. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space  
can support.  
____________ (volume of space) ÷ 50 cu. ft. = (Maximum Btu/Hr  
the space can support)  
Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. =  
51.2 or 51,200 (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.  
_________________ Btu/Hr (maximum the space can support)  
_________________ Btu/Hr (actual amount of Btu/Hr used)  
Example: 51,200 Btu/Hr (maximum the space can support)  
73,000 Btu/Hr (actual amount of Btu/Hr used)  
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:  
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 7.  
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 7.  
C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined.  
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space  
is an unconfined space. You will need no additional fresh air ventilation.

INSTALLING DAMPER CLAMP ACCESSORY FOR  
VENTED OPERATION  
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 non combustible  
material.  
INSTALLING  
Continued  
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.  
1. The fireplace does not meet the clearance to combustibles requirements for  
vent-free operation.  
2. State or local codes do not permit vent-free operation.  
3. You prefer vented operation.  
If reasons number 1 or 2 above apply to you, you must permanently open chimney flue  
damper. You must install the damper clamp accessory (to order, see Accessories, page  
31). This will insure vented operation (see Figure 10). The damper clamp will keep  
damper open. Installation instructions are included with clamp accessory.  
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.

CONNECTING TO GAS SUPPLY  
NOTICE  
A qualified service person must connect heater to gas supply.  
Follow all local codes.  
CAUTION  
Never connect heater directly to the propane supply. This heater  
requires an external regulator (not supplied). Install the external  
regulator between the heater and propane supply.  
Installation Items Needed  
Before installing heater, make sure you have the items listed below.  
• external regulator (supplied by  
installer, see page 16)  
• piping (check local codes)  
• sealant (resistant to LP gas)  
• manual shutoff valve *  
• test gauge connection *  
• sediment trap  
• tee joint  
• pipe wrench  
* An A.G.A. design-certified manual shutoff valve with 1/8" NPT tap is an acceptable  
alternative to test gauge connection. Purchase the optional A.G.A. design-certified manual  
shutoff valve from your dealer. See Accessories, page 31.

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 13. 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  
heater. 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 heater (see Figure 14, page 17).  
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 heater valves.  
CAUTION  
Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.  
Install sediment trap in supply line as shown in Figure 14, page 17. Locate sedi-  
ment trap where it is within reach for cleaning. 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.

A. This appliance has a pilot which must be lighted by hand. When lighting the pilot,  
follow these instructions exactly.  
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.  
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.  
• If you cannot reach your gas supplier, call the fire department.  
C. Useonlyyourhandtopushinorturnthegascontrolknob. Neverusetools. Iftheknob  
will not push in or turn by hand, don’t try to repair it, call a qualified service  
technician or gas supplier. Force or attempted repair may result in a fire or explosion.

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  
VENT-FREE PROPANE GAS LOG HEATERS  
DESA International warrants this product to be free from defects in materials and components for three (3) 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 MER-  
CHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE TO THREE (3) YEARS ON ALL COMPONENTS  
AND FIVE (5) YEARS ON STAINLESS STEEL BURNERS FROM THE DATE OF FIRST PURCHASE; AND DESA

INTERNATIONAL SHALL NOT BE LIABLE FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDI-  
RECT, 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.
