monoxide poisoning resemble the u, with head-

aches, dizziness or nausea. If you have these signs,

the replace may not be working properly. Get

fresh air at once! Have replace serviced. Some

people are more affected by carbon monoxide than

others. These include pregnant women, people with

heart or lung disease or anemia, those under the

inuence of alcohol and those at high altitudes.

Natural and Propane/LP

gases are odorless. An

odor-making agent is added to these gases. The

odor helps you detect a gas leak. However, the odor

added to the gas can fade. Gas may be present even

though no odor exists.

Make certain you read and understand all warnings.

Keep this manual for reference. It is your guide to

safe and proper operation of this replace.

1. This appliance is only for use with the type

of gas indicated on the rating plate. This ap-

pliance is not convertible for use with other

gases.

2. Do not place propane/LP supply tank(s) in-

side any structure. Locate propane/LP supply

tank(s) outdoors (propane/LP units only).

3. If you smell gas

• shut off gas supply

• do not try to light any appliance

• do not touch any electrical switch; do not use

any phone in your building

• immediately call your gas supplier from a

neighbor’s phone. Follow the gas supplier’s

instructions

• if you cannot reach your gas supplier, call

the re department

4. This heater shall not be installed in a bedroom

or bathroom, unless installed as a vented appli-

ance. See Installing Damper Clamp Accessory

for Vented Operation, page 12.

5. 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 qualied chimney cleaner. Creosote

will ignite if highly heated. A dirty chimney

ue may create and distribute soot within

the house. Inspect chimney ue for damage.

If damaged, repair ue and rebox before

operating heater.

6. Do not burn solid-fuel in a masonry or UL127

factory-built replace in which a vent-free

room heater is installed.

7. If replace has glass doors, never operate this

heater with glass doors closed. If you operate

heater with doors closed, heat buildup inside

replace will cause glass to burst. Make sure

there are no obstructions across openings of

replace.

8. To prevent the creation of soot, follow the

instructions in Cleaning and Maintenance,

page 23.

9. Before using furniture polish, wax, carpet

cleaner or similar products, turn heater off. If

heated, the vapors from these products may

create a white powder residue within burner

box or on adjacent walls and furniture.

10. This heater needs fresh, outside air ventilation

to run properly. This heater has an Oxygen

Depletion Sensing (ODS) safety shutoff sys-

tem. The ODS shuts down the heater if enough

fresh air is not available. See Air for Combus-

tion and Ventilation, page 6. If heater keeps

shutting off, see Troubleshooting, page 25.

11. Do not run heater

• where ammable liquids or vapors are used

or stored

• under dusty conditions

12. Do not use this heater to cook food or burn

paper or other objects.

13.

Do not use heater if any part has been exposed

to or under water. Immediately call a qualied

service technician to inspect the room heater

and to replace any part of the control system and

any gas control which has been under water.

14. Do not operate heater if any log is broken. Do

not operate heater if a log is chipped (dime-

sized or larger).

15. Turn heater off and let cool before servicing,

installing or repairing. Make sure the selector

switch is in the OFF position. Only a qualied

service person should install, service or repair

heater.

16. Make sure the selector switch is in the OFF

position when you are away from home for

long periods of time.

17. Remote-ready heaters must not be connected

to any external electrical source.

18. Operating heater above elevations of 4,500

feet may cause pilot outage.

19. To prevent performance problems, do not

use propane/LP fuel tank of less than 100 lb.

capacity (propane/LP units only).

20. Provide adequate clearances around air

openings.

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 ar-

eas 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.



This heater has a pilot with an Oxygen Deple-

tion 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.

ELECTRONIC IGNITION SYSTEM

This heater has an electronic ignitor to light heater

fuel supply.

LOCAL CODES

Install and use heater with care. Follow all local

codes. In the absence of local codes, use the lat-

est edition of The National Fuel Gas Code, ANSI

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.

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.

__________ 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)

73,000 Btu/Hr (actual amount of

Btu/Hr used)

The space in the above example is a conned 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 unconned

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, page 8.

C. Install a lower Btu/Hr replace, if lower Btu/Hr

size makes room unconned.

If the actual Btu/Hr used is less than the maximum

Btu/Hr the space can support, the space is an un-

conned space. You will need no additional fresh

air ventilation.

unconned space, you must provide two perma-

nent 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

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,

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 thermostat-

controlled power vent. Heated air entering the attic

will activate the power vent.

IMPORTANT: Vent-free heaters add moisture to

the air. Although this is benecial, installing heater

CHECK GAS TYpE

Use the correct type of gas (natural or propane/LP).

If your gas supply is not the correct gas type, do

not install heater. Call dealer where you bought

heater for proper type heater.
