PRODUCT FEATURES

OPERATION

This heater is clean burning. It requires no outside
venting. There is no heat loss out a vent or up a
chimney. Heat is generated by realistic dancing,
yellow flames. This heater is designed for vent-free
operation with flue damper closed. It has been
tested and approved to ANSI Z21.11.2 standard
for unvented heaters. This heater may also be
operated as a vented decorative (ANSI Z21.60)
product by opening flue damper (non-thermostat
models only).

SAFETY PILOT

This heater 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/pilot shuts off the heater if there
is not enough fresh air.

PIEZO IGNITION SYSTEM

This heater has a piezo ignitor. This system re­quires no matches, batteries or other sources to
light heater.

REMOTE CONTROL

ACCESSORIES

There are two optional remote controls that can be
purchased separately for this log heater:

• hand-held ON/OFF remote

• hand-held thermostat remote

See Accessories, page 34.

The hand-held thermostat may not be used where
vented decorative listing is required.

AIR FOR COMBUSTION

AND VENTILATION

WARNING: This heater shall
not be installed in a confined
space or unusually tight con
struction 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.

Todayʼs 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 effi
cient, 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.

AIR FOR COMBUSTION

AND VENTILATION

Continued

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 fol
lowing ventilation classifications:

1. Unusually Tight Construction

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 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 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 7.

If your home does not meet all of the three
criteria above, proceed to Determining
Fresh-Air Flow For Heater Location.

kg per pa-sec-m2) or

Confined Space and Unconfined Space

The National Fuel Gas Code, ANSI Z223.1/NFPA
54 defines a confined space as a space whose vol-

ume is less than 50 cubic feet per 1,000 Btu per hour

3

per kw) of the aggregate input rating of all

(4.8 m
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 m

3

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 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. 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: 2560 cu. ft. (volume of space) x 20 =

51,200 (maximum Btu/Hr the space can support)

3. Add the Btu/Hr of all fuel burning appliances in

the space.

__________Btu/Hr (actual amount of Btu/Hr used)

Example: 51,200 Btu/Hr (maximum the space

can support)

79,000 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 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 unconfined
space, remove door to adjoining room or add
ventilation grills between rooms. See Ventilation

Air From Inside Building.

B. Vent room directly to the outdoors. See Ventila

tion Air From Outdoors.

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,
confined 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,

unconfined space, you must provide two perma­nent openings: one within 12" of the ceiling and
one within 12" of the floor on the wall connecting
the two spaces (see options 1 and 2, Figure 2). You
can also remove door into adjoining room (see
option 3, Figure 2). Follow the National Fuel Gas

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or
ducts. You must provide two permanent openings:
one within 12" of the ceiling and one within 12"
of the floor. Connect these items directly to the
outdoors or spaces open to the outdoors. These
spaces include attics and crawl spaces. Follow the

National Fuel Gas Code, ANSI Z223.1/NFPA 54,
Section 5.3, Air for Combustion and Ventilation for

required size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for inlet

or outlet air into attic if attic has a thermostat­controlled power vent. Heated air entering the attic
will activate the power vent.

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
noncombustible material.

If you choose to use your heater as a manually­controlled model (no remote control installed),
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,

Accessories, page 34). This will insure vented

see
operation (see Figure 10, page 12). 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.

CONNECTING TO GAS SUPPLY

WARNING: This appliance
requires a 1/2" NPT (National
Pipe Thread) inlet connection to
the pressure regulator.

For propane/LP units, 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 pres
sure, heater regulator damage could occur. Install
external regulator with the vent pointing down
as shown in Figure 13. Pointing the vent down
protects it from freezing rain or sleet.

-

WARNING: A qualified ser­vice person must connect heater
to gas supply. Follow all local
codes.

CAUTION: Never connect
propane/LP heater directly to the
propane/LP supply. This heater
requires an external regulator
(not supplied). Install the exter­nal regulator between the heater
and propane/LP supply.

WARNING: Never connect
natural gas heater to private
(non-utility) gas wells. This
gas is commonly known as
wellhead gas.

Installation Items Needed

Before installing heater, make sure you have the
items listed below.

• piping (check local codes)

• sealant (resistant to propane/LP gas)

• equipment shutoff valve *

• test gauge connection *

• sediment trap

• tee joint

• pipe wrench

* A CSA design-certified equipment shutoff valve
with 1/8" NPT tap is an acceptable alternative to
test gauge connection. Purchase the optional CSA
design-certified equipment shutoff valve from your
dealer. See

Accessories, page 34.

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
volume 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 14,
page 14).

IMPORTANT:

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 re
quirements for locating equipment shutoff valve
to fireplaces.

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 heater 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
heater controls. If sediment trap is not installed or
is installed wrong, heater may not run properly.

CHECKING GAS CONNECTIONS

WARNING: Test all gas piping
and connections, internal and
external to unit, for leaks after
installing or servicing. Correct
all leaks at once.

WARNING: Never use an
open flame to check for a leak.
Apply a noncorrosive leak detec
tion fluid to all joints. Bubbles
forming show a leak. Correct all
leaks at once

3. Press the POWER and LOCK buttons
together to turn off the fireplace.

Auto (Thermostatic) Mode

1. Press the POWER and LOCK buttons
together to turn on the hand-held remote
control.

2. Press AUTO button to select this mode.

3. Set the desired room temperature by press
ing the TEMP + or - buttons.

4. Press the POWER and LOCK buttons

Do not leave the hand-held remote in

Note:

the AUTO mode close to the fireplace. The
radiant heat from the fireplace will turn off the
fireplace. Ideally, place the hand-held remote
in the center of the room facing towards the
fireplace.

Note: Do not hold the hand-held remote for
a long time. Body temperature will affect its
operation in the AUTO mode.

Safety Features

When away from home for an extended period
of time or as a child safety feature to prevent
accidental ignition of the fireplace, the receiver
ON/OFF/REMOTE switch should be in the
OFF position.

Auto Shutoff Feature

1. If the average room temperature exceeds
82 degrees Fahrenheit (28 degrees Centi
grade), the hand-held remote control will
perform a safety override and shut the
fireplace off. This feature is not available
in the MANU mode.

2. The receiver continuously receives signals
from the hand-held remote to control the
room temperature. If the hand-held remote
is misplaced, obstructed or for any reason
cannot transmit to the receiver, the receiver
will shut off the fireplace after 8 minutes.

Key Pad Lock Feature

This feature allows the user to lock/unlock
the keypad on the hand-held remote in the
MANU or AUTO mode to prevent inadvertent
operation (i.e. children operating the hand-held
remote control, etc.). The keypad is locked in
either on or off. Press the POWER and LOCK
buttons together to turn the unit on or off.

INSPECTING BURNERS

Check pilot flame pattern and burner flame pat­terns often.

PILOT FLAME PATTERN

Figure 37 shows a correct pilot flame pattern.
Figure 38, shows an incorrect pilot flame pattern.
The incorrect pilot flame is not properly heating
the thermocouple. When the thermocouple cools,

-

the heater will shut down. If pilot flame pattern is
incorrect, as shown in Figure 38

• turn heater off (see To Turn Off Gas to Appli
ance, page 20)

• see Troubleshooting

Note: The pilot flame on natural gas units will
have a slight curve, but the flame should be blue
and have no yellow or orange color.

CLEANING AND

MAINTENANCE

WARNING: Turn off heater

and let cool before cleaning.

CAUTION: You must keep con­trol areas, burners 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, pet
hair, bedding material, etc.

4. Check the injector holder located at the end
of the burner tube again. Remove any large
particles of dust, dirt, lint or pet hair 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 as
sembly. There is a small pilot air inlet hole about
two inches from where the pilot flame comes out
of the pilot assembly (see Figure 40). 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.

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 flame. 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 qualified 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 com
pressed air in a can, please follow the directions on
the can. If you donʼt 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 39).

3. Blow air through the ports/slots and holes in
the burner.

LOGS

-

• If you remove logs for cleaning, refer to Install-
ing Logs, page 17, to properly replace logs.

• Replace log(s) if broken or chipped (dime-sized
or larger).

MAIN BURNER

Periodically inspect all burner flame holes with the
heater running. All slotted burner flame holes should
be open with yellow flame present. All round burner
flame holes should be open with a small blue flame
present. Some burner flame holes may become
blocked by debris or rust, with no flame present. If
so, turn off heater and let cool. Remove blockage.
Blocked burner flame holes will create soot.

WARRANTY INFORMATION

111161 01

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

VENT-FREE GAS LOG HEATERS

DESA Heating Products warrants this product to be free from defects in materials and components for two (2)
year 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 Heating
Products Authorized Service Center. Warranty part(s) MUST be obtained through authorized dealers of this product
and/or DESA Heating Products 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) YEAR
ON ALL COMPONENTS FROM THE DATE OF FIRST PURCHASE; AND DESA HEATING PRODUCTSʼ
LIABILITY IS HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA HEAT
ING PRODUCTS 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.
