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 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.
10. This unit complies with ANSI Z21.11.2-2001 Unvented
Heaters and also complies with ANSI Z21.60-2000 Decorative Vented Appliances for Solid Fuel Burning Fireplaces. 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 appliances 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 provided. See page 8.

IMPORTANT SAFETY INFORMATION
Continued from page 3
16. Keep room area clear and free from combustible materials, 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 appliance.
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 appliance 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 m
3
per 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 m
3
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.
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 10
11
kg per pa-sec-m
2
) 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.

Figure 1 - Example of a Large Room with 1/2 Wall Divider
The following formula can be used to determine the maximum heater rating per the definition of unconfined space:
BTU/Hr = (L
1
+ L
2
) Ft x (W) Ft x (H) Ft
50 x 1000
Consider two connecting rooms with an open area between, with the following dimensions:
L
1
= 15
1
/
2
Ft., L
2
= 12 Ft., W = 12 Ft., H = 8 Ft.
BTU/Hr = (15
1
/
2
+ 12) x (12) x (8)
50 x 1000 = 52800 BTU/Hr
If there were a door between the two rooms the calculation would be based only on the room with the heater.
BTU/Hr = (15
1
/
2
) x (12) x (8)
50 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.

(Refer toTable).
Figure 3 - Reference Drawing of a Natural Flame Log Set in an Enclosure
Barriers such as the bottom of a glass door frame placed in front of a gas log set can change the air flow characteristics of the fireplace which in turn can cause the unit to overheat and malfunction.
NOTE: Non combustible material such as refractory brick may be used to line the floor of the fireplace in order to raise the height of the gas log set in relation to a restrictive barrier. If the unit is raised, the minimum height dimension listed in the homeowner’s manual must not be exceeded.
NOTE: If the log set is equipped with a remote receiver, a restrictive barrier may reduce the battery life by increasing the ambient temperature inside the fireplace. Placement of the receiver outside of the fireplace will extend the battery life.

• Seal any fresh air vents and/or ash clean-out doors located on the floor or wall of the fireplace. If left unsealed, drafting may cause pilot outage or sooting. Use a heat resistant sealant. Do not seal the chimney flue damper.
Before installing in a solid fuel burning fireplace, The chimney flue and firebox must be cleaned of soot, creosote, ashes and loose paint by a qualified chimney cleaner.
INSTALLING VENTED APPLICATIONS
Manual, milli-volt and Hi/Lo controlled gas logs may be installed as a vented decorative log set in compliance with ANSI
Z21.60 and National Fuel Gas Code, Section 6.6. Since, the gas logs are operated with the damper open, non-combustible
material and minimum mantel requirements do not apply.
This appliance is for installation only in a solid fuel burning fireplace (masonry fireplace or manufactured fireplace) with a working flue and constructed of noncombustible material.
Exception: DO NOT install this appliance in a factory-built fireplace that includes instructions stating that it has not been tested or should not be used with unvented gas logs. This log set may be installed as a vented log set.
BEFORE INSTALLING THE APPLIANCE:
• Turn off gas supply to fireplace or firebox.
• Have the fireplace floor and chimney professionally cleaned to remove ashes, soot, creosote or other obstructions.
Have this cleaning performed annually after installation.
• Seal any fresh air vents or ash clean-out doors located on floor or wall of fireplace. If not, drafting may cause pilot outage or sooting. Use a heat-resistant sealant.
Install and operate the appliance as directed in this manual.
DAMPER STOP INSTALLATION:
A damper stop must be provided with the unit. Contact your dealer to obtain one. The damper stop must be installed as shown in Figure 13 to prevent full closure of the fireplace damper blade and provide a minimum
29 square inch flue opening.

INSTALLING VENTED APPLICATIONS
The fireplace and gas logs function as a system. If the fireplace is spilling into the room
(check with a match or a smoke stick), reposition the damper clamp until a positive draft is obtained by opening the damper. If negative pressure in home prevents having a positive draft, contact your dealer for assistance.
PLACING AND SECURING APPLIANCE
You must secure the gas log heater to the fireplace floor. If not, the entire unit may move when you adjust the controls. Movement of unit may cause shifting of the gas logs which leads to sooting and improper burning. Grate movement could cause a gas leak.
Special care is required if you are installing the unit into a sunken fireplace.
You must raise the fireplace floor to allow access to gas log controls. This will insure adequate air flow and guard against sooting. Raise the fireplace floor using noncombustible materials, as described in “Placement in a Fireplace with Restrictive
Barrier” on page 11.
ASSEMBLY PROCEDURE:
1. Center the gas log unit in the fireplace or firebox. Make certain the front feet of the grate sit inside the front edge of the fireplace or firebox.
2. Anchor holes are located on the right and left sides of the unit. After centering the grate correctly, mark the hole positions on the fireplace/firebox floor. Drill two (2)

FLAME APPEARANCE
PLACING THE DECORATIVE ROCK
DO NOT sprinkle volcanic rock on the logs, around the pilot, or on or near burners. This may cause sooting. Place volcanic rock only on the floor of the fireplace.
During initial operation of the new heater, burning logs will give off a paper burning smell and orange flames will be present. Simply open the windows for a few hours to vent the odor.
Flames from the pilot, front and rear burner should be visually checked as soon as the heater is installed.
In addition, periodically check the flames visually during operation.
CHECKING THE PILOT FLAME
The pilot flame must always be present when the heater is in operation. It should just touch the top of the thermocouple tip for natural. See Figures 28 and 30 for correct pilot flame.
If the pilot flame does not touch the thermocouple, then the main burner cannot function reliably. See Figures 29 and 31 for incorrect shape of pilot flame.

CHECKING THE BURNER FLAME
In normal operation at full rate after 15 minutes, the following flame appearances should be observed:
Glowing Embers
Figure 32 - Correct Appearance of Rear Flames
The left and right rear flames should be yellow and extend 1"-2" above the mid log top surfaces. The yellow flames should
not contact the logs. There should be glowing embers on the middle log. Note: The front flames and embers will be
an opaque orange color during the burn off time.
OPERATING INSTRUCTIONS
Avoid any drafts that alter burner flame patterns. Do not allow fans to blow directly into the fireplace. Do not place a blower inside the burn area of the firebox. Ceiling fans may create drafts that alter flame patterns. Sooting and improper burning will result.
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 will be slight and will disappear with continued use.
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. See Figure 3, page 11.
