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 both

realistic ames and glowing coals. This heater is designed for vent-free operation with ue

damper closed. It has been tested and approved to ANSI Z21.11.2 standard for unvented heaters. State and local codes in some areas prohibit the use of vent-free heaters. This heater may also be operated as a vented decorative (ANSI

Z21.60) product by opening the ue damper

(non-thermostat models only).

AIR FOR COMBUSTION AND VENTILATION

WARNING: This heater shall not be installed in a room or space unless the required volume of indoor combustion air is provided by the method described in the

National Fuel Gas Code, ANSI Z223.1/NFPA 54, the International Fuel Gas Code, or applicable lo-

cal codes. 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 efcient 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

ef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, 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, Air for Combustion and Ventilation.

www.desatech.com

SAFETY DEVICE

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.

All spaces in homes fall into one of the three

following ventilation classications:

1. Unusually Tight Construction

2. Unconned Space

3. Conned 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 dened 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 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 FreshAir Flow For Heater Location, page 7.

AIR FOR COMBUSTION AND VENTILATION

Continued

Conned and Unconned Space

The National Fuel Gas Code, ANSI Z223.1/ NFPA 54 denes a conned space as a space

whose volume is less than 50 cubic feet per 1,000 Btu/hr (4.8 m3 per kw) of the aggregate

input rating of all appliances installed in that

space and an unconned space as a space whose volume is not less than 50 cubic feet per 1,000 Btu/hr (4.8 m3 per kw) of the ag-

gregate 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 unconned 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 Conned or Unconned Space

Use this work sheet to determine if you have a conned or unconned 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) = 2,560 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: 2,560 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 heater ___________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 * 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 heater + __________Btu/Hr Total = __________Btu/Hr

4. Compare the maximum Btu/Hr the space can

support with actual amount of Btu/Hr used.

_______ Btu/Hr (maximum the space can

support)

_______ Btu/Hr (actual amount of Btu/Hr

used)

Example: 5 1,200 Btu/Hr (maxim um the

space can support)

73,000 Btu/Hr (actual amount of

Btu/Hr used)

The space in the example is a conned 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 unconned space, remove door to adjoining room or add ventilation grills between

rooms. See Venti lation Air From Inside Building, page 8.

B. Vent room directly to the outdoors. See

Ventilation Air From Outdoors, page 8.

C. Install a lower Btu/Hr heater, if lower Btu/Hr

size makes room unconned.

40,000 33,000 73,000

If the actual Btu/Hr used is less than the

maximum Btu/Hr the space can support, the space is an unconned space. You will need

no additional fresh air ventilation.

the International Fuel Gas Code, or applicable local codes.

VENTILATION AIR

Ventilation Air From Inside Building

This fresh air would come from an adjoining unconned space. When ventilating to an adjoining unconned space, you must provide two permanent openings: one within 12" of the

ceiling and one within 12" of the oor 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 Code, ANSI

Z223.1/NFPA 54, Air for Combustion and Ventilation for required size of ventilation

grills or ducts.

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 oor. 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, 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 thermo-

stat-controlled power vent. Heated air entering the attic will activate the power vent.

INSTALLATION

NOTICE: This heater is intended for use as supplemental heat. Use this heater along with your primary heating system. Do not install this heater as your primary heat source. If you have a central heating system, you may

run system’s circulating blower

while using heater. This will help circulate the heat throughout the house. In the event of a power outage, you can use this heater as your primary heat source.

WARNING: A qualied service person must install heater. Follow all local codes.

NOTICE: State or local codes may only allow operation of this appliance in a vented conguration. Check your state or local codes.

WARNING: Make sure the selector switch is in the OFF position before installing heater (Remote-Ready Models Only).

WARNING: Before installing

in a solid fuel burning replace, the chimney ue and rebox

must be cleaned of soot, creosote, ashes and loose paint by a qualified chimney cleaner. Creosote will ignite if highly

heated. A dirty chimney ue and rebox may create and distribute

soot within the house. Inspect chimney flue for damage. If damaged, repair flue before operating heater.

WARNING: Seal any fresh air vents or ash clean-out doors located on oor or wall of replace. If not, drafting may cause pilot outage or sooting. Use a heat-resistant sealant. Do not

seal chimney ue damper.

WARNING: Never install the heater

• in a bedroom or bathroom

unless installed as a vented appliance, see page 11

• in a recreational vehicle

• where curtains, furniture, cloth-

ing, or other ammable objects

are less than 42" from the front, top, or sides of the heater

• in high trafc areas

• in windy or drafty areas

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 uids, 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 benecial, installing heater in rooms without enough ventilation air may cause mildew to form from too much

moisture. See Air for Combustion and Ventilation, page 6.

to the replace, you must install appliance at least 5" above the combustible ooring

(see Figure 9).

INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED OPERATION

Note: When used as a vented heater, appliance must be installed only in a solid-fuel burning replace with a working ue and constructed of noncombustible material.

For Massachusetts Residents Only: Installation of this vented gas log set in the Com-

monwealth of Massachusetts requires the damper be permanently removed or welded

in the fully open position.

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 replace does not meet the clearance

to combustibles requirements for ventfree 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 ue damper. You must install the damper clamp accessory (to order, see Accessories, page

33). This will insure vented operation (see Fig-

ure 10). The damper clamp will keep damper

open. Installation instructions are included

with clamp accessory. See the following chart for minimum perma-

nent ue opening you must provide. Attach

damper clamp so the minimum permanent

ue 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.

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

CAUTION: Never connect

propane/LP replace 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 replace 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.

• external regulator (supplied by installer)

• 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-certied equipment shutoff

valve with 1/8" NPT tap is an acceptable al-

ternative to test gauge connection. Purchase

the optional CSA design-certied equipment

shutoff valve from your dealer.

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" of water. If you do not re-

110399-01J14

INSTALLATION

Continued

duce incoming gas pressure, heater regulator

damage could occur. Install external regulator

with the vent pointing down as shown in Figure

15. 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 shut-

off 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 16 or 17, depending on

your model). 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 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 16 or 17,

depending on your model. 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 sedi-

ment trap is not installed or is installed wrong,

heater may not run properly.

Safety Features

When away from home for an extended period

of time or as a child safety feature to prevent

accidental ignition of the replace, the receiver ON/OFF/REMOTE switch should be in the

OFF position.

Auto Shutoff Feature

1. If the average room temperature reaches

a range of 82° F (28° C) to 92° F (33° C), the hand-held remote control will perform a safety override and shut the replace 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 replace. This will

occur in 8 or more minutes depending upon location of remote transmitter and strength of batteries.

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 ame pattern and burner ame

patterns often.

PILOT FLAME PATTERN

Figure 38 shows a correct pilot ame pattern. Figure 39 shows an incorrect pilot ame pattern. The incorrect pilot ame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.

If pilot ame pattern is incorrect, as shown

in Figure 39

• turn heater off (see To Turn Off Gas to Appliance, page 21 or page 24)

• see Troubleshooting, page 28

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, burners, and circulating air passageways of heater clean. Inspect these areas of heater before each use. Have heater inspected yearly

by a qualied 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.

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 ame. Keep these holes clear of dust, dirt, lint, and pet hair. Clean these air in-

let 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 qualied 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. 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 dam-

age the pilot assembly.

1. Shut off unit, including pilot. Allow 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 Figures 40 and 41).

3. Blow air through the ports/slots and holes

in the burner.

4. Check injector holder located at the end of the burner tube again. Remove any large

110399-01J 27

www.desatech.com

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 pilot ame indicates dust and dirt in the pilot

assembly. 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 unit off, lightly blow air through air inlet hole. You may blow through a drinking straw

if compressed air is not available.
