shock, and carbon monoxide poisoning.

WHAT TO DO IF YOU SMELL GAS

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.

Installation and service must be performed by a qualied installer, service agency, or local gas supplier.

WARNING: Do not store or use gasoline or other ammable vapors or liquids in the vicinity of this or any

other appliance.

This appliance is for use with only the type of gas indicated on the rating plate. This appliance is not
convertible for use with other gases.

CARBON MONOXIDE POISONING: Early signs of carbon monoxide poisoning resemble the u, with head-
aches, dizziness, or nausea. If you have these signs, the heater may not be working properly. Get fresh air
immediately! Have heater serviced. Some people are more affected by carbon monoxide than others. These

include pregnant women, persons with heart or lung disease or anemia, those under the inuence of alcohol,

and those at high altitudes.

QUALIFIED INSTALLING AGENCY

Installation and replacement of gas piping, gas utilization equipment or accessories and repair and servicing of
equipment shall be performed only by a qualied agency. The term “qualied agency” means any individual, rm,

corporation, or company that either in person or through a representative is engaged in and is responsible for:

The installation, testing, or replacements of gas piping or

The connection, installation, testing, repair, or servicing of equipment; that is experienced in such work; that

is familiar with all precautions required; and that has complied with all the requirement of the authority hav­ing jurisdiction.

In areas that prohibit the use of vent-free heaters, the log set has been tested and approved to the ANSI Z21.60
standard for Vented Decorative Logs. When used as a vented log set refer to additional instructions on page 11.

a)

b)

WARNING: This heater shall not be installed in a conned space or unusually tight construction unless pro-

visions are provided for adequate combustion and ventilation air. Read the following instructions to insure
proper fresh air for this and other fuel-burning appliances in your home.

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. Homeowners weather strip and caulk around windows and doors
to keep the cold air out and the warm air in. During heating months, homeowners 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.

PRODUCING ADEQUATE VENTILATION

The following are excerpts from National Fuel Gas Code. NFPA 54/ANS Z223.1. Air for Combustion and Ventila­tion. All spaces in homes fall into one of the three following ventilation classications:

1. Unusually Tight Construction

2. Unconned Space

3. Conned Space

The information on pages 5 through 7 will help you classify your space and provide adequate ventilation.

Conned and Unconned Space

The National Fuel Gas Code ANSI Z223.1 denes a conned space as a space whose volume is less than 50

cubic feet per 1,000 Btu per hour (4.8 cubic meter per kilowatt) of the aggregate input rating of all appliances in

-

stalled in that space, and an unconned space as a space whose volume is not less than 50 cubic feet per 1,000

Btu per hour (4.8 cubic meter per kilowatt) of the aggregate input rating of all appliances installed in that space.
Rooms connecting directly with the space in which the appliances are installed*, through openings not furnished

with doors, are considered a part of the unconned space.

This heater shall not be installed in a confined space or unusually tight construction unless provisions are
provided for adequate combustion and ventilation air.

*Adjoining rooms are connecting only if there are doorless passageways or ventilation grills between them.

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 dened as construction where:

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

Determining if You Have a Conned or Unconned Space

Use this worksheet to determine if you have a conned or unconned space.

Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways
or ventilation grills between the rooms.

1. Determine the volume of the space
Length×Width×Height= cu.ft. (volume of space)
Example: Space size 20 ft. (length) × 16 ft.(width) × 8 ft. (ceiling height) = 2560 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. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support.
(volume of space) ÷ 50 cu. ft.= (Maximum Btu/Hr the space can support)

3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free heater
Gas water heater*
Gas furnace
Vented gas heater
Gas heater logs
Other gas appliances* +
Total =

*Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors.

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)
71,000 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 maximum

Btu/Hr the space can support. You must provide additional fresh air. Your options are as follows:

Rework worksheet, adding the space of an adjoining 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

Outdoors”, page 7.
Vent room directly to the outdoors. See “Ventilation Air From Outdoors”, page 7.
Install a lower Btu/Hr heater, 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 unconned space. You will need no ad-

ditional fresh air ventilation.

WARNING: If the area in which the heater may be operated is smaller than that dened as an unconned

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. Air for combustion

and ventilation or applicable local codes.

Figure 3 - Ventilation Air from Outdoors

Ventilation Air From Inside Building

This fresh air would come from adjoining unconned space. When
ventilating to an adjoining unconned space, you must provide two

permanent openings: one within 12 inches of the wall connect

­ing the two spaces (see options 1 and 2, Figure 2). You can also
remove door into adjoining room (see option 3, Figure 2). Follow
the National Fuel Gas Code NFPA 54/ANSI Z223.1. Section 5.3,

Air for Combustion and Ventilation for required size of ventilation

grills or ducts.

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or duct. You must
provide two permanent openings: one within 12 inches of the
ceiling and one within 12 inches 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 NFPA 54/ANSI Z223.1, 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.

WARNING: Rework worksheet, adding the space of the ad-

joining unconned space. The combined spaces must have

enough fresh air to supply all appliances in both spaces.

PRODUCT FEATURES:

This log set has been tested and approved to ANSI Z21.11.2 standard for Unvented Heaters and can be operated with

the ue damper closed. State and local codes in some areas prohibit the use of vent-free heaters.

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.

THERMOSTAT HEAT CONTROL

The control automatically cycles the burner on and off to maintain a
desired room temperature.

PIEZO IGNITION SYSTEM

This heater is equipped with an electronic piezo ignitor. This system

requires AAA batteries (provided).

CAUTION: Do not remove the metal data plates from the grate assem-

bly. The data plates contain important product information.

WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS

Water vapor is a by-product of gas combustion. An unvented room heater produces approximately one (1) ounce
(30ml) of water for every 1,000 BTUs (.3KWs) of gas input per hour. Unvented room heaters are recommended
as supplemental heat (a room) rather than a primary heat source (an entire house). In most supplemental heat
applications, the water vapor does not create a problem. In most applications, the water vapor enhances the low
humidity atmosphere experienced during cold weather.

The following steps will help insure that water vapor does not become a problem.

1. Be sure the heater is sized properly for the application, including ample combustion air and circulation air.

2. If high humidity is experienced, a dehumidier may be used to help lower the water vapor content of the air.

3. Do not use an unvented room heater as the primary heat source.

WARNING: A qualied technician must install heater. Follow all local codes.

WARNING: Before installing in a solid ue burning rebox, 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.

WARNING: Maintain the minimum clearances.

If possible, provide greater clearances from the

oor, ceiling, and adjoining wall than required.
