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
Confined Space and Unconfined
Space
The following are excerpts from National
Fuel Gas Code. NFPA 54/ANS Z223.1, Section 5.3, Air for Combustion and Ventilation.
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.
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 (6x10-11 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.
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 to Determining Fresh-Air Flow For Heater
Location on page 5.

DETERMINING FRESH-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: 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
Example:
Gas water heater*
________________________ Btu/Hr
40,000
Gas water heater

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: 51,200 Btu/Hr (maximum 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 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.

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 noncombustible 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 ventfree 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
30). 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

WARNING: You must secure
this heater to fireplace floor. If
not, heater will move when you
adjust controls. Moving heater
may cause a gas leak.
WARNING: If installing in a
sunken fireplace, special care is
needed. You must raise the fireplace floor to allow access to
heater control panel. This will insure adequate air flow and guard
against sooting. Raise fireplace
floor with noncombustible material. Make sure material is secure.
CAUTION: Do not pick up
heater base assembly by the
burner. This could damage
heater. Only handle base assembly by grates.
CAUTION: Do not remove the
metal Data Plates attached to the

WARNING: 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 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 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.
We recommend that you install sediment
trap in supply line as shown in Figure 13.
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.
CAUTION: Avoid damage to
regulator. Hold gas regulator with
wrench when connecting it to gas
piping and/or fittings.

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.
ODS/PILOT AND BURNER
• Use a vacuum cleaner or small, soft
bristled brush to clean.
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 29).
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 hairs 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 30). 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.

OPTIONAL POSITIONING OF THERMOSTAT SENSING
BULB
For Masonry and Factorybuilt Metal Fireplace
If your log set cycles to pilot, but the
room temperature drops to a lower
than ideal comfort level before the log
set comes back on, you may want to
reposition the thermostat sensing bulb.
The thermostat sensing bulb is located near
the gas valve assembly on the mounting
bracket. This location allows the thermostat
to keep the room temperature at an ideal
comfort level for most fireplace applications. For positioning the thermostat sensing bulb elsewhere, an adhesive-backed
mounting clip is available.
Tools needed: 1/4" hex driver or socket
1. Remove logs. Locate the gas valve assembly and thermostat sensing bulb
(see Figure 31).
2. With 1/4" hex driver or socket, loosen
the thermostat screw. Carefully slide
the thermostat sensing bulb out of the
retaining clamp (see Figure 33).
Note: Do not remove the screw. Make
sure you tighten the screw after removing the thermostat sensing bulb.
IMPORTANT: Do not force or bend the
thermostat sensing bulb or capillary.
3. The thermostat sensing bulb may be
located to the lower right front side of
fireplace. Determine location of sensing bulb, but do not mount sensing bulb
until step 5. If you have a masonry fireplace, see Figure 34 for location. If you
have a factory-built metal fireplace, see
Figure 35 for location. If your fireplace
has glass doors, position sensing bulb
directly behind door gap on right bottom side (see Figure 36).
4.
The mounting clip must be a minimum
of 3" from bottom of fireplace to prevent crimping of capillary. Once you
have decided on a location, clean the
area thoroughly. Remove the paper
backing from the adhesive on back of
mounting clip. Press the clip into the
new location so that the thermostat
sensing bulb will be positioned vertically with the capillary at the bottom
(see Figure 37). Slide the thermostat
sensing bulb into the clip.
IMPORTANT: Do not crimp capillary.

WARRANTY INFORMATION
KEEP THIS WARRANTY

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 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.
