AIR FOR COMBUSTION AND
VENTILATION
WARNING: This firebox shall not be installed in a
confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air. Read the following instructions to insure proper fresh air for this and other fuelburning appliances in your home.
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, fireboxes, 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 are excerpts from National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation.
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 5 through 7 will help you classify your
space and provide adequate ventilation.
AIR FOR COMBUSTION AND VENTILATION
Unusually tight construction is defined as construction
where:
a. walls and ceilings e xposed to the outside atmosphere
have a continuous water vapor retar der with a rating
of one perm (6 x 10
openings gasketed or sealed
b. weather stripping has been added on openable win-
dows and doors
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 additional fresh air. See
From Outdoors

Confined and Unconfined Space
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
a space whose volume is not 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. 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.
* Adjoining rooms are communicating only if there are doorless
passageways or ventilation grills between them.
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.

DETERMINING FRESH-AIR FLOW FOR
FIREBOX LOCATION
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.
1. Determine the volume of the space (length x width x height).
Length x Width x Height =___________ cu. ft. (volume of space)
Example:
height) = 3168 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
Example:
Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
* Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors.
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:
Space size 22 ft. (length) x 18 ft. (width) x 8 ft. (ceiling
can support)
3168 cu. ft. (volume of space) x 20 = 63,360 (maximum
Vent-free heater _____________ Btu/Hr
Gas water heater* _____________ Btu/Hr
Gas furnace _____________ Btu/Hr
Vented gas heater _____________ Btu/Hr
Gas fireplace logs _____________ Btu/Hr
Other gas appliances* + _____________ Btu/Hr
Total = _____________ Btu/Hr
Example:
Gas water heater _____________ Btu/Hr
Vent-free heater + _____________ Btu/Hr
Total = _____________ Btu/Hr
63,360 Btu/Hr (maximum the space can support)
79,000 Btu/Hr (actual amount of Btu/Hr used)
40,000
39,000
79,000
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 V entilation Air Fr om
Inside Building, page 7.
B. Vent room directly to the outdoors. See Ventilation Air From Out-
doors, page 7.
C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room un-
confined.
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.
WARNING: If the area in which the heater may be
operated is smaller than that defined as an unconfined space or if the building is of unusually tight
construction, provide adequate combustion and ventilation air by one of the methods described in the
National Fuel Gas Code, ANSI Z223.1/NFPA 54 Section 5.3
or applicable local codes

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 FIREBOX
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. As with all concrete liners, this liner may develop
slight cracks when exposed to heat. This cracking is considered normal. 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 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.
