PRODUCT FEATURES
OPERATION
This vent-free replace insert 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 ames and glowing embers. When
used without the blower, the replace insert requires no electricity making it ideal for emergency
backup heat.
SAFETY DEVICE
This replace insert has a pilot with an Oxygen
Depletion Sensing (ODS) safety shutoff system.
The ODS/pilot is a required feature for vent-free
room heaters. The ODS system shuts off the replace insert if there is not enough fresh air.
PIEzO IGNITION SYSTEM
This replace insert has a piezo ignitor. This system requires no matches, batteries or other sources
to light replace insert.
BLOWER ASSEMBLY
This replace insert is equipped with a blower
assembly. The blower operates thermostatically
and has a variable control. The blower circulates
heated air from the replace insert into the room.
Use of blower is optional.
AIR FOR COMBUSTION
AND VENTILATION
WARNING: This heater shall
not be installed in a conned
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 efcient
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 efcient, 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, replaces, 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 are excerpts from National Fuel
Gas Code ANSI Z223.1/NFPA 54, Section 5.3, Air
for Combustion and Ventilation.
All spaces in homes fall into one of the three following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 6 through 8 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 dened as construction where:
a. walls and ceilings exposed to the out-
side atmosphere have a continuous
water vapor retarder with a rating of
one perm (6 x 10
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 oors, 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 8.
If your home does not meet all of the three
criteria above, proceed to Determining
Fresh-Air Flow for Heater Location, page 7.

Conned and Unconned Space
The National Fuel Gas Code ANSI Z223.1/NFPA 54
denes a conned 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 unconned
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 unconned space.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation grills
between them.
DETERMINING FRESH-AIR FLOW
FOR HEATER LOCATION
Determining if You Have a Conned or
Unconned Space
Use this work sheet to determine if you have a
conned or unconned space.
Space: Includes the room in which you will install
replace 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. Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
__________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example: 3168 cu. ft. (volume of space) x 20 =
63,360 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in
the space.
Vent-free replace ___________ Btu/Hr
Gas water heater* ___________ Btu/Hr
Gas furnace ___________ Btu/Hr
Vented gas heater ___________ Btu/Hr
Gas replace logs ___________ Btu/Hr
Other gas appliances* + ___________ Btu/Hr
Total = ___________ Btu/Hr
113195-01C7
www.desatech.com
* Do not include direct-vent gas appliances. Di-
rect-vent draws combustion air from the outdoors
and vents to the outdoors.
Example:
Gas water heater __________ Btu/Hr
Vent-free replace + _________ Btu/Hr
Total = _________ Btu/Hr
4. Compare the maximum Btu/Hr the space can
support with the actual amount of Btu/Hr used.
_________
_________
Example: 63,360 Btu/Hr (maximum the space
73,000 Btu/Hr (actual amount of
The space in the above example is a conned space
because the actual Btu/Hr used is more than the maxi-
mum 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 adjoin-
ing room. If the extra space provides an unconned
space, remove door to adjoining room or add
ventilation grills between rooms. See Ventilation
Air From Inside Building, page 8.
B. Vent room directly to the outdoors. See Ventila-
tion Air From Outdoors, page 8.
C. Install a lower Btu/Hr replace, if lower Btu/Hr
size makes room unconned.
If the actual Btu/Hr used is less than the maximum
Btu/Hr the space can support, the space is an un-
conned space. You will need no additional fresh
air ventilation.

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 replace
insert. If pipe is too small, undue
loss of volume will occur.
Installation must include an equipment shutoff
valve and plugged 1/8" NPT tap. Locate NPT
tap within reach for test gauge hook up. NPT
tap must be upstream from replace insert (see
Figure 14).
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.
Check your building codes for any special requirements for locating equipment shutoff valve
to replaces.
Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant from
going into pipe. Excess sealant in pipe could result
in clogged replace valves.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
We recommend that you install a sediment trap in
supply line as shown in Figure 14. 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 replace insert gas controls. If sediment trap

OPTIONAL BLOWER
OPERATION
Locate the blower switch by opening lower lou-
ver on replace insert. Blower switch is located
at lower left inside louver door.
This thermostat-controlled blower has three
settings: ON, OFF and AUTO. In the ON position, the blower will operate constantly. In the
OFF position, the blower will not operate. In
the AUTO position, the blower will start when
the thermostat senses a sufcient increase in
rebox temperature.
Note: Your gas logs and thermostat blower
will not turn on and off at the same time. The
replace insert may run for several minutes
before the blower turns on. After the heater
modulates to the pilot position, the blower will
continue to run. The blower will shut off after
the rebox temperature decreases.
Note: It is safe to operate replace insert with
blower turned off. However, the blower helps
distribute heated air from the replace insert.
INSPECTING BURNERS
Check pilot ame pattern and burner ame patterns often.
PILOT FLAME PATTERN
Figure 36 shows a correct pilot ame pattern.
Figure 37 shows an incorrect pilot ame pattern.
The incorrect pilot ame is not properly heating
the thermocouple. When the thermocouple cools,
the heater will shut down.
If pilot ame pattern is incorrect, as shown in
Figure 37
• turn heater off (see To Turn Off Gas to Appli-ance, page 20)
• see Troubleshooting, page 25
Note: The pilot ame on natural gas units will
have a slight curve, but ame should be blue and
have no yellow or orange color.

BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes in
the tting at the burner entrance. These holes may
become blocked with dust or lint. Periodically
inspect these holes for any blockage and clean if
needed. Blocked air holes will create soot.
MAIN BURNER
Periodically inspect all burner ame holes with
the heater running. All slotted burner ame holes
should be open with yellow ame present. All
round burner ame holes should be open with a
small blue ame present. Some burner ame holes
may become blocked by debris or rust, with no
ame present. If so, turn off heater and let cool.
Remove blockage, blocked burner ame holes
will create soot.
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
qualied service person. Heater
may need more frequent cleaning due to excessive lint from
carpeting, pet hair, bedding
material, etc.
WARNING: Failure to keep
the primary air opening(s) of
the burner(s) clean may result in
sooting and property damage.
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 ame. Keep these holes clear of dust, dirt,
lint and pet hair. Clean these air inlet holes prior to
each heating season. Blocked air holes will create
soot. We recommend that you clean the unit every
three months during operation and have heater
inspected yearly by a qualied service person.
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.

Clean the pilot assembly also. A yellow tip on the
pilot ame indicates dust and dirt in the pilot as-
sembly. There is a small pilot air inlet hole about
2" from where the pilot ame comes out of the
pilot assembly (see Figure 41). 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.
LOGS
• If you remove logs for cleaning, refer to Installing Logs, page 17, to properly replace logs.
• Replace log(s) if broken or chipped (dime-sized
or larger).
BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes in
the tting at the burner entrance. These holes may
become blocked with dust or lint. Periodically
inspect these holes for any blockage and clean if
needed. Blocked air holes will create soot.
