W ARNINGS
IMPORTANT: Read this owner’s manual carefully and completely before
trying to assemble, operate, or service this heater. Improper use of this
heater can cause serious injury or death from burns, fire, explosion,
electrical shock, and carbon monoxide poisoning.
DANGER
Carbon monoxide poisoning may lead to death!
Carbon Monoxide Poisoning: Early 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.
Natural Gas: Natural 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.

AIR FOR
WARNING
COMBUSTION
AND
VENTILATION
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 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 continuous
water vapor retarder with a rating of one perm (6x10
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
If your home does not meet all of the three criteria above, proceed to page 6.

Confined Space 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
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.

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:
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:
Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
Example:
* 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 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.
Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) =
2560 cu. ft. (volume of space)
2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum

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.
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
29). 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.

• pipe wrench
W ARNING
Never connect heater to private (non-utility) gas wells. This gas is
commonly known as well-head gas.
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 13, 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 13, page 17. 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.

OPERATING
FOR YOUR SAFETY READ BEFORE LIGHTING
HEATER
W ARNING
If you do not follow these instructions exactly, a fire or explosion may
result causing property damage, personal injury or loss of life.
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. Use only your hand to push in or turn the gas control knob. Never use tools. If the
knob 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.
D. Do not use this appliance if any part has been under water. Immediately call a
qualified service technician to inspect the appliance and to replace any part of the
control system and any gas control which has been under water.
LIGHTING INSTRUCTIONS
W ARNING
• If fireplace has glass doors, never operate this heater with glass doors
closed. If you operate heater with doors closed, heat buildup inside
fireplace will cause glass to burst. Also if fireplace opening has vents at
the bottom, you must open the vents before operating heater.
• You must operate this heater with a fireplace screen in place. Make sure
fireplace screen is closed before running heater.

NOTICE
During initial operation of new heater, burning logs will give off a paperburning smell. Orange flame will also be present. Open damper or
window to vent smell. This will only last a few hours.
Note:
Homeowners generally prefer to operate their heater with the chimney damper
closed. This will put all the heat into the room. However there may be times you will
desire the full flames of the Hi heat setting but will find the heat output excessive. You
can open the chimney damper (if you have one) fully or partially to release some of
the heat. WARNING: Damper handle will be hot if heater has been running.
1. STOP! Read the safety information above.
2. Make sure manual shutoff valve is fully open.
3. Press in and turn control knob clockwise
Ignitor Button

LIMITED WARRANTY
COMFORT GLOW VENT-FREE NATURAL GAS LOG HEATERS
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.
