PRODUCT FEATURES
AIR FOR COMBUSTION AND VENTILATION
This fireplace shall not be installed in a confined space 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.
WARNING
Today's homes are built more energy efficient than ever. New materials, increased insula-
tion, 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, fireboxes, 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.
Operation
This Vent-free Gas Fireplace requires no outside venting or chimney making installation easy
and inexpensive. When used without the optional blower (model VF32B), the firebox
requires no electricity making it ideal for emergency backup heat.
Blower Accessory
The VFZC32 Vent-free Gas Fireplace will accept the VF32B Blower Kit accessory. The kit
comes with the variable blower. The variable blower allows you to select the fan speed you
desire. The blower circulates heated air from the firebox into the room. Use of the blower is
optional.
Planning
Plan where you will install the fireplace. This will save time and money later when you install
the fireplace. Before installation, consider the following:
1. Where the fireplace will be located. Allow for wall and ceiling clearances (see
Installation Clearances, pages 10 & 11).
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).

AIR FOR COMBUSTION AND VENTILATION CONTINUED
Providing adequate ventilation
The following is excerpts 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 Construction; 2. Unconfined Space; 3. Confined Space.
The information on pages 6 through 10 will help you classify your space and provide ad-
equate 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 retarder with a rating of one perm (6x10 per pa-sec-m ) or 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 10.
If your home does not meet all of the three criteria above, proceed to page 8.
Confined Space and Unconfined Space
The National Fuel Gas Code (ANSI Z223.1, 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 (4.8m 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 (4.8m 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.

AIR FOR COMBUSTION AND VENTILATION CONTINUED
Determining if You Have a Confined or Unconfined Space
Use this worksheet to determine if you have a confined or unconfined space.
Space: Includes the room in which you will install the firebox 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 22 ft. (length) x 18 ft. (width) x 8 ft. (ceiling height) =
3168 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)
Example: 3168 cu. Ft. (volume of space) 50 cu. Ft. = 63.3 or 63,300 (maximum
BTU/Hr the space can support)
3. Add the BTU/Hr of all fuel-burning appliances in the space.
Vent-free Firebox __________________ BTU/Hr
Gas water heater* __________________ BTU/Hr
Gas furnace __________________ BTU/Hr
Vented gas heater __________________ BTU/Hr
Gas firebox logs __________________ BTU/Hr
Other gas appliances* + __________________ BTU/Hr
Total = __________________ BTU/Hr
Example: Gas water Heater 40,000 BTU/Hr
Vent-free firebox with log heater + 39,000 BTU/Hr
Total = 79,000 BTU/Hr
* 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: 63,300 BTU/Hr (maximum the space can support)
79,000 BTU/Hr (actual amount of BTU/Hr used)
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 worksheet, 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.

9
AIR FOR COMBUSTION AND VENTILATION CONTINUED
B. Vent room directly to the outdoors. See Ventilation Air from Outdoors, page 10.
C. Install a lower BTU/Hr firebox, 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.
WARNING
If the area in which the firebox and gas log heater may be operated is smaller than
that defined as an unconfined space, provide adequate combustion and
ventilation air by one of the methods described in the National Fuel Gas Code,
ANSI Z223.1, 1992, Section 5.3.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining unconfined space. When ventilating to an ad-
joining unconfined space, you must provide two permanent openings: one within 12" of the
ceiling and one within 12" of the floor into adjoining room ( see options in Figure 1).
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.
WARNING
Rework worksheet, adding the space of the adjoining unconfined space. The
combined spaces must have enough fresh air to supply all appliances in both
spaces.
Figure 1 - Ventilation Air from Inside Building

10
AIR FOR COMBUSTION AND VENTILATION CONTINUED
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. (See Figure 2)
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
Maintain the minimum clearances. If you can, provide greater clearances from
floor, ceiling, and adjoining wall.
INSTALLATION CLEARANCES
Carefully follow the instructions below. This will ensure safe installation.
Minimum Wall and Ceiling Clearances (see Figure 3)
A. Clearances from the side of the firebox opening to any combustible wall should not
be less than 6 inches. (This applies to built-in installation or using an (optional) cabinet
mantel kit.)
B. Clearances from the top of the firebox opening to the ceiling should not be less than
42 inches.
