IMPORTANT SAFETY INFORMATION

10. This unit complies with ANSI Z21.11.2-2001 Unvented

Heaters and also complies with ANSI Z21.60-2000 Deco-

rative Vented Appliances for Solid Fuel Burning Fire-

places. State and local codes may only allow operation

of this appliance in a vented configuration. Check your

state or local codes. For vented operation, see “Vented

Instructions” in this manual.

11. Do not install the heaters in a bathroom or bedroom.

12. Correct installation of the ceramic fiber logs, proper

location of the heater, and annual cleaning are necessary

to avoid potential problems with sooting. Sooting,

resulting from improper installation or operation,

can settle on surfaces outside the fireplace. See log

placement instructions for proper installation.

13. Avoid any drafts that alter burner flame patterns. Do not

allow fans to blow directly into fireplace. 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.

14. Caution: Candles, incense, oil lamps, etc. produce

combustion byproducts including soot. Vent-free appli-

ances will not filter or clean soot produced by these types

of products. In addition, the smoke and/or aromatics

(scents) may be reburnt in the vent-free appliance which

can produce odors. It is recommended to minimize the

use of candles, incense, etc. while the vent-free appliance

is in operation.

15. This is an unvented gas-fired heater. It uses air (oxygen)

from the room in which it is installed. Provisions for

adequate combustion and ventilation air must be pro-

vided. See page 8.

INSTALLER

Please leave these instructions with the appliance.

OWNER

Please retain these instructions for future reference

IMPORTANT

Read these instructions carefully before installing or trying to operate this vent-free gas heater.

1. Due to high temperatures, the appliance should

be located out of traffic and away from furniture

and draperies.

2. Children and adults should be alerted to the hazard

of high surface temperature and should stay away to

avoid burns or clothing ignition.

3. Young children should be carefully supervised when

they are in the same room with the appliance.

4. Do not place clothing or other flammable material

on or near the appliance.

5. Any safety screen or guard removed for servicing an

appliance, must be replaced prior to operating the

heater.

6. Installation and repair should be done by a qualified

service person.

7. To prevent malfunction and/or sooting, an unvented

gas heater should be cleaned before use and at least

annually by a professional service person. More fre-

quent cleaning may be required due to excessive lint

from carpeting, bedding material, etc. It is imperative

that control compartments, burners and circulating air

passageways be kept clean.

8. 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.

9. The installation must conform with local codes or, in

the absence of local codes, with the National Fuel Gas

Code, ANSI Z223.l/NFPA54. Continued on page 4

• 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.

IMPORTANT SAFETY INFORMATION

Continued from page 3

16. Keep room area clear and free from combustible materi-

als, gasoline and other flammable vapors and liquids.

17. Unvented gas heaters are a supplemental zone heater.

They are not intended to be the primary heating appli-

ance.

18. Unvented gas heaters emit moisture into the living area.

In most homes of average construction, this does not pose

a problem. In houses of extremely tight construction,

additional mechanical ventilation is recommended.

19. During manufacturing, fabricating and shipping, various

components of this appliance are treated with certain

oils, films or bonding agents. These chemicals are not

harmful but may produce annoying smoke and smells

as they are burned off during the initial operation

of the appliance; possibly causing headaches or eye

or lung irritation. This is a normal and temporary

occurrence.

The initial break-in operation should last two to three

hours with the burner at the highest setting. Provide

maximum ventilation by opening windows or doors to

allow odors to dissipate. Any odors remaining after this

initial break-in period will be slight and will disappear

with continued use.

20. 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 should be reduced 4 percent for

each 1,000 feet above sea level. Refer to the National

Fuel Gas Code.

21. The appliance and its appliance main gas 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).

22. The appliance must be isolated from the gas supply

piping system by closing its equipment shutoff 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).

23. Do not use this room 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 which has been under

water.

24. This appliance must not be used with glass doors in the

closed position. This can lead to pilot outages and severe

sooting outside the fireplace.

25. Never burn solid fuels in a fireplace where a unvented

room heater is installed.

26. Always have a fireplace screen in place when the appli-

ance is in operation and, unless other provisions for

combustion air are provided, the screen must have an

opening(s) for induction of combustion air.

ADEQUATE COMBUSTION AND VENTILATION AIR

This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided for

adequate combustion and ventilation air.

The National Fuel Gas Code, (ANSI Z223.1/NFPA 54), defines a confined space as a space whose volume is less than 50

cubic feet per 1,000 BTU per hour (4.8 m3per kw) of the aggregate input rating of all appliances installed in that space. An

unconfined space is defined as a space whose volume is not less than 50 cubic feet per 1,000 BTU per hour (4.8 m3per 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.

UNUSUALLY TIGHT CONSTRUCTION IS DEFINED AS CONSTRUCTION WHERE…

a) walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of 1 perm

(6 x 1011 kg per pa-sec-m2) or less with openings gasketed or sealed;

b) weather striping 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.

44D0060 9

The following formula can be used to determine the maximum heater rating per the definition of unconfined space:

BTU/Hr = (L1+ L2) Ft x (W) Ft x (H) Ft

Consider two connecting rooms with an open area between, with the following dimensions:

L1= 151/2Ft., L2= 12 Ft., W = 12 Ft., H = 8 Ft.

BTU/Hr = (151/2 + 12) x (12) x (8)

If there were a door between the two rooms the calculation would be based only on the room with the heater.

BTU/Hr = (151/2) x (12) x (8)

x 1000

x 1000 = 52800 BTU/Hr

x 1000 = 29760 BTU/Hr

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.
