objects on the heater.
WARNINGS
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, and carbon monoxide poisoning.
Surface of heater becomes very
hot when running heater. Keep
children and adults away from
hot surface to avoid burns or
clothing ignition. Heater will remain hot for a time after shutdown. Allow surface to cool before touching.
DANGER: Carbon monoxide
poisoning may lead to death!
Carefully supervise young children when they are in the same
room with heater.
Carbon Monoxide Poisoning: Early signs
of carbon monoxide poisoning resemble the
flu, with headaches, dizziness, and/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 natural gas.
The odor helps you detect a natural gas leak.
However, the odor added to natural gas can
fade. Natural gas may be present even though
no odor exists.
Make sure grill guard is in place
before running heater.
Keep the appliance area clear and
free from combustible materials,

NATURAL GAS HEATER
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 fuelburning 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 10-11 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.
Confined 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.
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 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. 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: 2560 cu. ft. (volume of 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
Example:
Gas furnace
______________ Btu/Hr
Gas water heater
44,000 Btu/Hr
Vented gas heater
______________ Btu/Hr
Vent-free heater + 10,000 Btu/Hr
Gas fireplace logs
______________ Btu/Hr
Total
= 54,000 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)
54,000 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, ANS Z223.1, Section 5.3 or applicable local codes.

If installing bottom mounting screw into
hollow or solid wall, install wall anchor.
Follow steps 1 through 4 under Attaching To Wall Anchor Method, page 8. If
installing bottom mounting screw into
wall stud, drill holes at marked locations using 9/64" drill bit.
Replace heater onto mounting bracket.
Place spacer between bottom mounting hole and wall anchor or drilled hole.
Hold spacer in place with one hand.
With other hand, insert mounting screw
through bottom mounting hole and
spacer. Place tip of screw in opening
of wall anchor or drilled hole.
Tighten screw until heater is firmly secured
to wall. Do not over tighten. Note: Do not
replace front panel at this time. Replace
front panel after making gas connections
and checking for leaks. (see page 10).
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 3/8"
diameter or greater to allow
proper gas volume to heater. If
pipe is too small, undue loss of
pressure will occur.
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 13).
IMPORTANT: Install an equipment shutoff
valve in an accessible location. The equipment shutoff valve is for turning on or
shutting off the gas to the appliance.
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. 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.
IMPORTANT: Hold pressure regulator with
wrench when connecting it to gas piping
and/or fittings

THERMOSTAT
CONTROL
OPERATION
The thermostatic control used on this
model differs from standard thermostats.
Standard thermostats simply turn on and
off the burner. The thermostat used on
this heater senses the room temperature.
At times the room may exceed the set
temperature. If so, the burner will shut
off. The burner will cycle back on when
room temperature drops below the set
temperature. The control knob can be set
to any comfort level between 1 and 7.
Note: The thermostat sensing bulb measures the temperature of air near the
heater cabinet. This may not always agree
with room temperature (depending on
housing construction, installation location, room size, open air temperatures,
etc.) Frequent use of your heater will let
you determine your own comfort levels.

INSPECTING
BURNER
WARNING: If yellow tipping
occurs, your heater could produce increased levels of carbon
monoxide. If burner flame pattern shows yellow tipping, follow
instructions below.
NOTICE: Do not mistake orange
flames with yellow tipping. Dust
or other fine particles enter the
heater and burn causing brief
patches of orange flame.
If burner flame pattern is incorrect, as shown
in Figure 23
• turn heater off (see To Turn Off Gas to
Appliance, page 11 for non-thermostat
models or page 12 for thermostat model)
• see Troubleshooting, pages 14 through 16
Check pilot flame pattern and burner flame
pattern often.
PILOT FLAME PATTERN
Figure 20 shows a correct pilot flame pattern.
Figure 21 shows an incorrect pilot flame
pattern. 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 21
• turn heater off (see To Turn Off Gas to
Appliance, page 11 for non-thermostat
models or page 12 for thermostat model)

CLEANING BURNER
PILOT AIR INLET HOLE
We recommend that you clean the unit every
2,500 hours of operation or every three months.
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 for dust and dirt.
3. Blow air through the ports/slots and
holes in the burner.
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 24). 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.

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
COMFORT GLOW VENT-FREE RESIDENTIAL GAS 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 only the cost of part(s) required to restore this
heater to proper operating condition. 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 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.
