AIR FOR COMBUSTION AND VENTILATION
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 product (ANSI Z21.60) by opening flue damper (non-thermostat operation only).
APPLICATION
These multisided logs are designed to be equally beautiful when viewed from any angle. They are designed specifically for use in see-through, peninsula, and island fireboxes with multiple open­ings. You may also install this log heater in a standard firebox.
WARNING: This heater shall not be installed in a confined space or unusually tight construction un­less provisions are provided for adequate combus­tion and ventilation air. Read the following instruc­tions to insure proper fresh air for this and other fuel­burning appliances in your home.
Today’s 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 efficient, 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, 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 following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space The information on pages 4 through 6 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 outside atmosphere
have a continuous water vapor retar der with a rating of one perm (6x10 openings gasketed or sealed
b. weather stripping has been added on openable win-
dows and doors
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
From Outdoors
, page 6.
If your home does not meet all of the three criteria above, proceed to
Heater Location
Confined and Unconfined Space
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 m3 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 (4.8 m3 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.
* 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 heater 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:
height) = 2560 cu. ft. (volume of space) If additional ventilation to adjoining room is supplied with grills or open-
ings, 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 = (Maximum Btu/Hr the space
Example:
Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
* 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:
Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling

Continued
The space in this 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 additional fresh air. Your options are as follows:
A. Rework worksheet, adding the space of an adjoining room. If the ex-
tra space provides an unconfined space, remove door to adjoining room or add ventilation grills between rooms. See V entilation Air From Inside Building.
B. Vent room directly to the outdoors. See Ventilation Air From Out-
doors.
C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room un-
confined.
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconfined space. You will need no additional fresh air ventilation.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor on the wall connecting 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, ANSI Z223.1/NFPA 54, 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 ducts. You must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor. 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, ANSI Z223.1/ NFPA 54, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts.
IMPORTANT:
attic if attic has a thermostat-controlled power vent. Heated air entering the attic will activate the power vent.
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.

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 vented mode:
1. The fireplace does not meet the clearance to combustibles re-
quirements 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 24). This will insure vented operation (see Figure 10). The damper clamp will keep damper open. Installation instructions are included with clamp accessory.
See chart below for minimum permanent flue opening you must provide. Attach damper clamp so the minimum permanent flue opening will be maintained at all times.
