PRODUCT
FEATURES
Operation
This stove is designed to accept all gas log heaters listed in Table 1, page 2. It requires
no outside venting or chimney making installation easy and inexpensive. When used
without the blower, the stove requires no electricity making it ideal for emergency backup heat.
Blower Accessory
The stove will accept the GA3700 accessory. The variable blower allows you to
select the fan speed you desire. The blower circulates heated air from the stove into
the room. Use of blower is optional.
LOCATING
STOVE
AIR FOR
COMBUSTION
AND
VENTILATION
Planning
Plan where you will install the stove. This will save time and money later when you
install the stove. Before installation, consider the following:
1. Where the stove will be located. Allow for wall and ceiling clearances (see
Installation Clearances, page 10).
2. Everything needed to complete installation.
3. These models CANNOT be installed in a bedroom or bathroom.
4. Proper air for combustion and ventilation (see below).
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
fuel-burning 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, stoves, 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 is exerpts from National Fuel Gas Code. NFPA 54/ANSI Z223.1,
Section 5.3, Air for Combustion and Ventilation.
All spaces in homes fall into one of the three following ventilation classifications:
1. Unusually Tight Contruction; 2. Unconfined Space; 3. Confined Space.
The information on pages 6 through 9 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 continu-
ous water vapor retarder with a rating of one perm or less with open-
ings gasketed or sealed
b. weather stripping has been added on openable windows 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
If your home does not meet all of the three criteria above, proceed to page 8.
Ventilation Air From Outdoors
and
, page 9

Confined and Unconfined Space
The National Fuel Gas Code (ANSIZ2123.1, 1992 Section 5.3) 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 AIR FLOW FOR STOVE 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 stove 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:
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)
Example:
3. Add the Btu/Hr of all fuel burning appliances in the space.
Example:
* 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:
The space in the above 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 work sheet, adding the space of an adjoining 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, page 9.
B. Vent room directly to the outdoors. See Ventilation Air from Outdoors, page 9.
C. Install a lower Btu/Hr gas log, 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, the space is
an unconfined space. You will need no additional fresh air ventilation.
Space size 22 ft. (length) x 18 ft. (width) x 8 ft. (ceiling height) =
3168 cu. ft. (volume of space)
3168 cu. ft. (volume of space) ÷ 50 cu. ft. = 63.3 or 63,300 (maximum
Btu/Hr the space can support)
Vent-free stove ___________________ Btu/Hr
Gas water heater* ___________________ Btu/Hr
Gas furnace ___________________ Btu/Hr
Vented gas heater ___________________ Btu/Hr
Stove logs ___________________ Btu/Hr
Other gas appliances* + ___________________ Btu/Hr
Total = ___________________ Btu/Hr
Gas water heater 40,000 Btu/Hr
Vent-free stove with log heater + 30,000 Btu/Hr
Total = 70,000 Btu/Hr
63,300 Btu/Hr (maximum the space can support)
70,000 Btu/Hr (actual amount of Btu/Hr used)
W ARNING
If the area in which the stove and gas log heater may be operated is
smaller than that defined as an unconfined space or if the building
is of unusually tight contruction, provide adequate combustion and
ventilation air by one of the methods described in the
Gas Code, ANSI Z223.1, Section 5.3
or applicable local codes.
