CGFP28P and CGFP28PT
UNVENTED PROPANE/LP GAS FIREPLACE
PRODUCT
FEATURES
OPERATION
This vent-free fireplace is clean burning. It
requires no outside venting. There is no heat
loss out a vent or up a chimney. Heat is
generated by both realistic flames and glowing embers. The fireplace requires no electricity making it ideal for emergency backup heat.

SAFETY FEATURES
This fireplace has a pilot with an Oxygen
Depletion Sensor Shutoff System (ODS).
The ODS/pilot is a required feature for ventfree room heaters. The ODS system protects
against oxygen depletion and any interruption in the fuel supply. If either occurs, the
ODS shuts off gas flow to the burner, turning the fireplace off. An internal regulator
controls fluctuations in your gas pressure.

PIEZO IGNITION SYSTEM
This fireplace has a piezo ignitor. This system requires no matches, batteries, or other
sources to light fireplace.

THERMOSTAT CONTROL
MODELS (CGFP28PT)
These fireplaces have a thermostat sensing
bulb and a control valve. The thermostat
controls the heat output and flame height.
This maintains a consistent room temperature. Even the lowest setting provides realistic flames and glowing embers from two
burners. Selecting higher comfort settings
allows fireplace to run longer, producing
greater heat output. At lower comfort settings, the fireplace will run less. This results
in increased heating comfort. This can also
result in lower gas bills. An optional thermostatically (GA3650T) or manually
(GA3750) controlled blower is available
(see Accessories, page 32).

VARIABLE MANUAL
CONTROL (CGFP28P)
These fireplaces have a variable manual control valve which allows the user to choose the
heat setting that best suits his needs. Any
setting between low and high may be selected
by simply turning the control knob. An optional manually controlled blower (GA3750)
is available (see Accessories, page 32).

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.

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.
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 Fireplace
Location, page 5..

Confined Space and Unconfined
Space
The National Fuel Gas Code (ANS Z223.1,
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.

Unusually Tight Construction

This heater shall not be installed in a confined space or unusually tight construction
unless provisions are provided for adequate
combustion and ventilation air.

The air that leaks around doors and windows may provide enough fresh air for
combustion and ventilation. However, in

* Adjoining rooms are communicating only
if there are doorless passageways or ventilation grills between them.

DETERMINING FRESH-AIR FLOW FOR FIREPLACE 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 fireplace 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 22 ft. (length) x 18 ft. (width) x 8 ft. (ceiling height) = 3168 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: 3168 cu. ft. (volume of space) ÷ 50 cu. ft. = 63.3 or 63,300 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.

___________________ 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.
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: 63,300 Btu/Hr (maximum the space can support)
68,000 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 work sheet, 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 fireplace, 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, 1992, Section 5.3 or applicable local codes.

NOTICE: A qualified service person must connect fireplace 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 fireplace, make sure you
have the items listed below.
• external regulator (supplied by installer,
see Figure 30)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• manual shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas connector (if allowed by local codes) (not
provided)
* 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 32.
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
30. Pointing the vent down protects it from
freezing rain or sleet.

Propane
Supply Tank

Vent Pointing Down

Figure 30 - External Regulator With Vent

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 fireplace. 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
fireplace (see Figure 31, page 15).
Check your building codes for any special
requirements for locating manual shutoff
valve to fireplaces.
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 fireplace valves.
CAUTION: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.
Install sediment trap in supply line as shown
in Figure 31, page 15. 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 fireplace gas controls. If
sediment trap is not installed or is installed
wrong, fireplace may not run properly.

VARIABLE MANUAL
CONTROL OPERATION

Check pilot flame pattern and burner flame
patterns often.

The variable control valve can be set to
any heat setting and flame height desired, by simply turning the control knob
until that setting is attained. Even the
lowest setting provides realistic flames
and glowing embers from two burners.
Selecting higher settings produces
greater heat output. This results in increased heating comfort.

Figure 45 shows a correct pilot flame pattern.
Figure 46 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 fireplace will shutdown.

WARNING: Do not operate
heater between pilot and high
positions.
CAUTION: Do not try to adjust heating levels by using the
manual shutoff valve.

PILOT FLAME PATTERN

If pilot flame pattern is incorrect, as shown
in Figure 46
• turn fireplace off (see To Turn Off Gas to
Appliance, page 18 [Thermostat-controlled models} or column 1, this page,
[Manually-controlled models])
• see Troubleshooting, pages 22 through 24

flame pattern shows yellow tipping, your fireplace could produce increased levels of carbon
monoxide. Follow instructions at
bottom of this page. Yellow flame
on rear burner is normal.
NOTICE: Do not mistake orange
flames with yellow tipping. Dirt
or other fine particles are burned
by fireplace, causing brief
patches of orange flame.
If front burner flame pattern is incorrect, as
shown in Figure 48
• turn fireplace off (see To Turn Off Gas to

OWNER’S MANUAL
CLEANING AND
MAINTENANCE

3.
4.

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

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, and lint. Clean these
air inlet holes prior to each heating season.
Blocked air holes will create soot. 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, and primary air
inlet holes on injector holder for dust
and dirt (see Figure 49).

103414

5.
6.

Blow air through the ports/slots and
holes in the burner.
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.
Blow air into the primary air holes on
the injector holder.
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 50). 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

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 PROPANE/LP GAS FIREPLACE
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.
