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, heaters, 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 fuelburning 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 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.
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
unconfining 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 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 10-11 kg
per pa-sec-m2) or less with openings 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 additional fresh air. See Ventilation Air
From Outdoors, page 6.
If your home does not meet all of the
three criteria above, proceed to Determining Fresh-Air Flow For Heater
Location, page 5.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Confined or Unconfined Space
Use this worksheet 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: 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. 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 can support)
Example: 2560 cu. ft. (volume of space) x 20 = 51,200 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free heater
_________________ Btu/Hr
Gas water heater*
_________________ Btu/Hr
Example:
Gas water heater

_________________ 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: 51,200 Btu/Hr (maximum the space can support)
69,000 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 6.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 6.
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.
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.

CONNECTING TO GAS
SUPPLY
WARNING: A qualified service
person must connect heater to gas
supply. Follow all local codes.
Installation Items Needed
Before installing heater, make sure you have
the items listed below.
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
* An CSA design-certified equipment
shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA designcertified equipment shutoff valve from your
dealer. See Accessories, page 24.
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 6).
We recommend that you install a sediment
trap in supply line as shown in Figure 6.
Locate sediment trap where it is within
reach for 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.
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.

PILOT FLAME PATTERN
Figure 23 shows a correct pilot flame pattern. Figure 24 shows an incorrect pilot
flame pattern. (Note: Appearance of pilot
assembly may vary by model). The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to
cool. When the thermocouple cools, the heater
will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 24
• turn heater off (see To Turn Off Gas to
Appliance)

OPERATION
In the ON position, the blower will start
when the thermostat senses a sufficient
increase in firebox temperature (approximately 10 to 20 minutes depending on
heat setting). Note: Your gas stove and
thermostat blower will not turn on and
off at the same time. The stove may run
for several minutes before the blower
turns on. After the heater modulates to
the pilot position, the blower will continue to run. The blower will shut off
after the firebox temperature decreases.

Note: It is safe to operate stove with
blower turned off. However, the blower
helps distribute heated air from the stove.
Note: Periodically check the louvers of
the firebox and remove any dust, dirt, or
other obstructions.
The thermostat control knob can be set to
any comfort level between Hi and Lo. The
thermostat will gradually modulate the heat
output and flame height from higher to
lower settings, or pilot, in order to maintain
the comfort level you select. The ideal comfort setting will vary by household depending upon the amount of space to be heated,
the output of the central heating system, etc.

CLEANING AND
MAINTENANCE
WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep control areas, burner, and circulating
air passageways of heater clean.
Inspect these areas of heater before each use. Have heater inspected yearly by a qualified service person. Heater may need more
frequent cleaning due to excessive
lint from carpeting, bedding material, pet hair, etc.

Burner
Tube
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 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 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 27).
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 28).
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.

LOGS
• If you remove logs for cleaning, refer to
Installing Logs, page 10, to properly replace logs.
• Replace log(s) if broken or chipped
(dime-sized or larger).
MAIN BURNER
Periodically inspect all burner flame holes
with the heater running. All slotted burner
flame holes should be open with yellow
flame present. All round burner flame holes
should be open with a small blue flame
present. Some burner flame holes may become blocked by debris or rust, with no flame
present. If so, turn off heater and let cool.
Either remove blockage or replace burner.
Blocked burner flame holes will create soot.
Review your video included with your heater
for additional cleaning instructions.

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 PEDESTAL STOVE
DESA International 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.
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 TWO (2) 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.
