signs of carbon monoxide poisoning resemble the flu, with headaches, dizziness,
or nausea. If you have these signs, the heater
may not be working properly. Get fresh air
at once! Have heater serviced. Some people
are more affected by carbon monoxide than
others. These include pregnant women,
people with heart or lung disease or anemia,
those under the influence of alcohol, and
those at high altitudes.
Propane Gas: Propane gas is odorless. An
odor-making agent is added to the gas. The
odor helps you detect a gas leak. However,
the odor added to the gas can fade. Gas may
be present even though no odor exists.

PRODUCT
FEATURES
Operation
This heater is clean burning. It requires no
outside venting. There is no heat loss out a
vent or up a chimney. Heat is generated by
realistic, dancing yellow flames. This heater
is designed for vent-free operation with flue
damper closed. State and local codes in
some areas prohibit the use of vent-free
heaters. You can operate heater as a vented
product by opening flue damper.
Safety Pilot
This heater has a pilot with an Oxygen
Depletion Sensor Shutoff System (ODS).
The ODS/pilot is a required feature for ventfree room heaters. The ODS/pilot shuts off
the heater if there is not enough fresh air.
Piezo Ignition System
This heater has a piezo ignitor. This system
requires no matches, batteries, or other
sources to light heater.
AIR FOR
COMBUSTION AND
VENTILATION
WARNING: 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.
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 fuelburning 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 3 through 5 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 (6x10
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 and Unconfined Space
The National Fuel Gas Code (ANSIZ223.1,
1992 Section 5.3) 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 in-
and
-11
kg
De-
stalled*, 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.
DETERMINING AIR FLOW
FOR HEATER 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:
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:
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.
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
Space size 20 ft. (length) x
2560 cu. ft. (volume of
Example:
Gas water heater 40,000 Btu/Hr
Vent-free heater + 31,500 Btu/Hr
Total = 71,500 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 can support)
71,500 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 Ventila-
tion Air From Inside Building, page 5.
B. V ent room directly to the outdoors. See
V entilation Air Fr om Outdoors, page 5.
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.

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.
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 clear-
ance 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
19). 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 above)
• 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 19.

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.
External
Regulator
Propane
Supply Tank
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).
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.
From External
Regulator (11"
W.C.** to 14"
W.C. Pressure)
Install sediment trap in supply line as shown
in Figure 14. Locate sediment 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.
CAUTION: Avoid damage to
regulator. Hold gas regulator with
wrench when connecting it to gas
piping and/or fittings.

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 PROPANE GAS LOG HEATERS
DESA International warrants this product to be free from defects in materials and components for three (3) 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 THREE (3) 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.
