AIR FOR
COMBUSTION AND
VENTILATION
WARNING: This heater 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 fuel-burning
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, 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 are excerpts from National
Fuel Gas Code NFPA 54/ANS 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 Construction
2. Unconfined Space
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.
Unusually tight construction is defined as construction where:
a. walls and ceilings exposed to the
outside atmosphere have a continuous water vapor retarder with
a rating of one perm (6 x 10
per pa-sec-m2) or less with openings gasketed or sealed
b. weather stripping has been
added on openable windows 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
If your home does not meet all of the
three criteria above, proceed to

Confined Space and Unconfined
Space
The National Fuel Gas Code ANS Z223.1
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.
This heater shall not be installed in a confined space or unusually tight construction
unless provisions are provided for adequate
combustion and ventilation air.
* Adjoining rooms are communicating only
if there are doorless passageways or ventilation grills between them.

DETERMINING FRESH-AIR FLOW FOR FIREPLACE 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 fireplace 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:
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:
3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free fireplace ___________________ 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
* 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:
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 work sheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoin-
ing room or add ventilation grills between rooms. See Ventilation Air from Inside Building, page 6.
B. Vent room directly to the outdoors. See Ventilation Air from Outdoors, page 6.
C. Install a lower Btu/Hr fireplace, 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.
Space size 22 ft. (length) x 18 ft. (width) x 8 ft. (ceiling height) = 3168 cu. ft. (volume of space)
3168 cu. ft. (volume of space) ÷ 50 cu. ft. = 63.3 or 63,300 (maximum Btu/Hr the space can support)
Example:
Gas water heater
Vent-free fireplace +
Total =
63,300 Btu/Hr (maximum the space can support)

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

CLEANING AND
MAINTENANCE
WARNING: Turn off fireplace
and let cool before cleaning.
CAUTION: You must keep
control areas, burners, and circulating air passageways of fireplace
clean. Inspect these areas of fireplace before each use. Have fireplace inspected yearly by a qualified service person. Fireplace may
need more frequent cleaning due
to excessive lint from carpeting,
bedding material, pet hair, etc.
CLEANING BURNER
INJECTOR HOLDER AND
PILOT AIR INLET HOLE
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 cat 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 recommend
using compressed air no greater than 30 PSI.
Your local computer store, hardware store, or
home center may carry compressed air in a
can. You can use a vacuum cleaner in the
blow position. If using compressed air in a
can, please follow the directions on the can.
If you don't follow directions on the can, you
could damage the pilot assembly.
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 35).
3. Blow air through the ports/slots and
holes in the burner.
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.
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.
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 36).
With the unit off, lightly blow air through the air
inlet hole. You may blow through a drinking
straw if compressed air is not available.

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, 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.
