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 realistic dancing, yellow flames. This heater is designed for vent-free operation with flue 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 flue damper (non-thermostat operation only).
SAFETY PILOT
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.
AIR FOR COMBUSTION
AND VENTILATION
WARNING: This heater shall not be installed in a confined space or unusually tight con­struction unless provisions are provided for adequate combus tion and ventilation air. Read the following instructions to insure proper fresh air for this and other fuel-burning appliances in your home.
Todayʼs homes are built more energy efficient 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 effi cient, your home needs to breathe. Fresh air must enter your home. All fuel-burning appliances need fresh air for proper combustion and ventilation.

AIR FOR COMBUSTION
AND VENTILATION
Continued
Exhaust fans, fireplaces, 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, Section 5.3, Air for Combustion and Ventilation.
All spaces in homes fall into one of the three fol lowing ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 5 through 7 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 defined 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 (6x10 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 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 7.
If your home does not meet all of the three criteria above, proceed to Determining Fresh-Air Flow for Heater Location.

Confined and Unconfined Space
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 and an unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour
3
(4.8 m
per kw) of the aggregate input rating of all appliances installed in that space. Rooms com municating directly with the space in which the appliances are installed*, through openings not furnished with doors, are considered a part of the unconfined 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 Confined or Unconfined Space
Use this work sheet to determine if you have a confined or unconfined space.
Space: Includes the room in which you will install fireplace 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.

Example: 51,200 Btu/Hr (maximum the space
can support)
79,000 Btu/Hr (actual amount of
Btu/Hr used)
The space in the example is a confined space because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support. You must provide ad ditional fresh air. Your options are as follows:
A. Rework worksheet, adding the space of an adjoin
ing room. If the extra space provides an unconfined 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.
C. Install a lower Btu/Hr fireplace, if lower Btu/Hr
size makes room unconfined.
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, confined space. You will need no additional fresh air ventilation.
WARNING: 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.

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 pri mary heat source. If you have a central heating system, you may run system’s circulating blower while using log heater. This will help circulate the heat from your log heater throughout the house. In the event of a power outage, you can use this heater as your primary heat source.
WARNING: Never install the
heater
• in a bedroom or bathroom unless installed as a vented
-
appliance (Variable Manually­Controlled Models Only) (see page 11)
• in a recreational vehicle
• where curtains, furniture, clothing or other flammable objects are less than 42 inches from the front, top or sides of the heater
• in high traffic areas
• in windy or drafty areas
WARNING: A qualified ser­vice person must install heater. Follow all local codes.
NOTICE: State or local codes may only allow operation of this appli­ance in a vented configuration. Check your state or local codes.
WARNING: 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. Creosote will ignite if highly heated. A dirty chimney flue may create and distribute soot within house. Inspect chimney flue and firebox for damage. If damaged, repair flue and firebox before operating heater.
WARNING: 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. Do not seal chimney flue damper.
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 flu­ids, 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 beneficial, installing heater in rooms without enough ventilation air may cause mildew to form from too much moisture. See Air
for Combustion and Ventilation
CHECK GAS TYPE
Use the correct gas type (natural or propane/LP) for your unit. If your gas supply is not correct, do not install heater. Call dealer where you bought heater for proper type heater.

INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED OPERATION
Note: When used as a vented heater, appliance must be installed only in a solid-fuel burning fireplace with a working flue and constructed of noncombustible material.
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
All
vented mode.
Models
1. The fireplace does not meet the clearance to combustibles requirements for vent-free operation.
2. State or local codes do not permit vent-free operation.
3. You prefer vented operation.
If reasons number 1 or 2 above apply to you, you must permanently open chimney flue damper. You must install the damper clamp accessory (to order, see Accessories, page 38). This will insure vented operation (see Figure 10). The damper clamp will keep damper open. Installation instructions are included with clamp accessory.

INSTALLING HEATER BASE ASSEMBLY
CAUTION: Do not remove the data plates attached to the heater base assembly. The data plates contain important warranty and safety information.
WARNING: You must secure this heater to fireplace floor. If not, heater will move when you adjust controls. Moving heater may cause a gas leak.
WARNING: If installing in a sunken fireplace, special care is needed. You must raise the fireplace floor to allow access to heater control panel. This will insure adequate air flow and guard against sooting and controls being damaged. Raise fireplace floor with noncombus­tible material. Make sure material is secure.
CAUTION: Do not pick up heater base assembly by the burner. This could damage heater. Only handle base as­sembly by grates.
IMPORTANT: Make sure the heater burners are level. If heater is not level, heater will not work properly. For thermostat models, avoid damage to thermostat bulb. Avoid nicks or sharp bends in thermostat bulb wire. Keep thermostat bulb in mounting bracket until ready to mount base to floor. See Optional Positioning Of Thermostat Sensing Bulb, page 28.
