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 vent­free 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 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 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 fol­lowing 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

-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 ar-

eas 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

.

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 (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.

* 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.

Vent-free fireplace __________ Btu/Hr

Gas water heater* __________ Btu/Hr

Gas furnace __________ Btu/Hr

Vented gas heater __________ Btu/Hr

Gas fireplace logs __________ Btu/Hr

Other gas appliances* + __________ Btu/Hr

Total = __________ Btu/Hr

www.desatech.com

111161-01D 7

* Do not include direct-vent gas appliances. Di­rect-vent draws combustion air from the outdoors
and vents to the outdoors.

Example:

Gas water heater _________ Btu/Hr

Vent-free fireplace + ________ Btu/Hr

Total = ________ Btu/Hr

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)

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 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 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, 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,

ANSI Z223.1/NFPA 54 Section

5.3

or applicable local codes

Ventilation Air From Inside Building

This fresh air would come from an adjoining un­confined space. When ventilating to an adjoining
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

CAUTION: This heater cre­ates warm air currents. These
currents move heat to wall sur­faces next to heater. Installing
heater next to vinyl or cloth wall
coverings or operating heater
where impurities (such as, but
not limited to, tobacco smoke,
aromatic candles, cleaning flu­ids, oil or kerosene lamps, etc.)
in the air exist, may discolor
walls or cause odors.

IMPORTANT:

Vent-free heaters add moisture to
the air. Although this is beneficial, installing heater
in rooms without enough ventilation air may cause
mildew to form from too much moisture. See Air
for Combustion and Ventilation, page 5.

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,
see Accessories, page 34). This will insure vented
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.

INSTALLING HEATER BASE
ASSEMBLY

CAUTION: Do not remove
the data plates attached to the
heater base assembly. The data
plates contain important war­ranty and safety information.

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 and controls be­ing damaged. Raise fireplace floor
with noncombustible material.
Make sure material is secure.

CAUTION: Do not pick up
heater base assembly by burners.
This could damage heater. Only
handle base assembly by grates.

IMPORTANT:

Make sure the heater burners are level.

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 pres­sure, 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.

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:

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 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.

INSTALLATION

CONNECTING TO GAS SUPPLY

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

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

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.

CAUTION: Avoid damage to
regulator. Hold gas regulator
with wrench when connecting it
to gas piping and/or fittings.

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 de­tection fluid to all joints. Bubbles
forming show a leak. Correct all
leaks at once

CAUTION: Make sure exter­nal regulator has been installed
between propane/LP supply and
heater. See guidelines under

under water.

LIGHTING

INSTRUCTIONS

WARNING:

• If fireplace has glass doors,
never operate this heater with
glass doors closed. If you op­erate heater with doors closed,
heat buildup inside fireplace
will cause glass to burst. Make
sure there are no obstructions
across opening of fireplace.

• You must operate this heater

closed before running heater.

NOTICE: During initial operation
of new heater, burning logs will
give off a paper-burning smell.
Orange flame will also be
present. Open damper or win­dow to vent smell. This will only
last a few hours.

Note:

Home owners generally prefer to oper­ate their heater with the chimney damper
closed. This will put all the heat into the room.
However, there may be times you will desire
the full flames of the HI heat setting but will
find the heat output excessive. You can open
the chimney damper (if you have one) fully or
partially to release some of the heat.

WARNING: Damper handle
will be hot if heater has been
running.

1. STOP! Read the safety information, col­umn 1.

2. Make sure equipment shutoff valve is fully
open.

3. Set selector switch in the OFF position.

1. If the average room temperature exceeds

82 degrees Fahrenheit (28 degrees Centi­grade), 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, page 24

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.

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 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 39).

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 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 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 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.

LOGS

• If you remove logs for cleaning, refer to In-

stalling 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

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 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 PROD­UCTS’ LIABILITY IS HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA
HEATING 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.
