Installation and repair must be done by a qualified service person. The appliance should be in-

spected before use and at least annually by a professional service person. More frequent cleaning

may be required due to excessive lint from carpeting, bedding material, etc. It is imperative that

control compartments, burners and circulating air passageways of the appliance be kept clean.

WARNING:ARNING:

ARNING:ARNING:

ARNING:

Any change to this heater or its controls can be dangerous. Improper installation or

use of the heater can cause serious injury or death from fire, burns, explosion or carbon monoxide

poisoning.

1. CARBON MONOXIDE POISONING:CARBON MONOXIDE POISONING:

CARBON MONOXIDE POISONING:CARBON MONOXIDE POISONING:

CARBON MONOXIDE POISONING: Early signs of carbon monoxide poisoning are similar to

the flu with headaches, dizziness and/or nausea. If you have these signs, obtain fresh air

immediately. Have the heater serviced as it may not be operating properly.

2. The installation must conform with local codes or, in the absence of local codes, with the National

Fuel Gas Code, ANSI Z223.1.

2. This heater shall not be installed in a bedroom or bathroom.

4. WW

WW

WARNING:ARNING:

ARNING:ARNING:

ARNING: Improper installation, adjustment, alteration, service or maintenance can cause

injury or property damage. Refer to this owner's manual. Installation and service must be

performed by a qualified installer, service agency or the gas supplier.

5. To prevent malfunction and/or sooting, a vent-free gas heater should be cleaned at least

annually by a professional service person. More frequent cleaning may be required due to

excessive lint from carpeting, etc. It is imperative that control compartments, burners and

circulating air passageways be kept clean.

6.

Correct placement of the ceramic fiber logs is necessary to avoid problems with sooting. Sooting

can settle on surfaces outside the heater and cause discoloration. See the appropriate sections

of this manual for instructions.

WW

WARNING:ARNING:

ARNING:ARNING:

ARNING:

Do not allow fans to blow directly into the fireplace. Avoid any drafts that alter burner

flame patterns. Do not place a blower inside burn area of firebox. Ceiling fans may create drafts

that alter burner flame patterns. Sooting and improper burning will occur.

8. This is a vent-free gas fired heater. It uses air (oxygen) from the room in which it is installed.

Provisions for adequate combustion and ventilation air must be provided. Refer to installation

guidelines.

9.

Children and adults should be alerted to the hazard of high surface temperature and should stay

away to avoid burns or clothing ignition.

10.

Young children should be carefully supervised when they are in the same room with the

appliance.

11. Do not place clothing or other flammable material near the appliance.

IMPORTANT SAFETY INFORMATION

CONTINUED

13. Keep appliance area clear and free from combustible materials, gasoline and other flammable

vapors and liquids.

15. Any safety screen or guard removed for servicing, must be replaced prior to heater operation.

16.

This vent-free gas heater is intended to be smokeless. If logs appear to smoke, turn off the

heater and call a qualified service person.

Initial burn off may cause slight smoke and odor

during the first four hours of operation.

17. Input ratings are shown in BTU per hour and are for elevations up to 2,000 feet. For elevations

above 2,000 feet, input ratings s

hould be reduced 4 percent per 1,000 feet above sea level.

Refer to the National Fuel Gas Code.

18. The appliance and its appliance main gas shut off valve must be disconnected from the gas

supply piping

system during any pressure testing of that system at test pressures in excess of 1/

2 psig (3.5 kPa).

19.

The appliance must be isolated from the gas supply piping system by closing its equipment

shut off valve during any pressure testing of the gas supply piping system at test pressures

equal

to or less than 1/2 psig (3.5 kPa).

20. Do not use this heater if any part has been under water. Immediately call a qualified service

technician to inspect the room heater and to replace any part of the control system and any

gas control that has been under water.

This heater shall not be installed in a confined space unless provisions are provided for adequate combus-

tion and ventilation air.

(a) Walls and ceiling exposed to the outside atmosphere have a continuous water vapor retarded

with a rating of 1 perm (6 x 10 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 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, gas lines, and at other openings.

The National Fuel Gas Code defines a confined space as a space whose volume is less than 50 cubic feet

per 1,000 BTU per hour (4.8m³ per kw) of the aggregate input rating of all appliances installed in that space

and an unconfined space is defined as a space whose volume is not less than 50 cubic feet per 1,000 BTU

per hour (4.8m³ 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 fur-

nished with doors, are considered a part of that unconfined space.

The following formula can be used to determine the maximum
