VANGUARD
UNVENTED (VENT-FREE) LOGMATE™ FIREBOX
PRODUCT
FEATURES
Operation
This firebox is designed for use with approved ANSI Z21.11.2 decorative type
unvented room heaters. (Physical size limitations apply. Refer to minimum firebox
requirements supplied with log heater.) It
requires no outside venting or chimney making installation easy and inexpensive. When
used without the blower (models FB36CA
or FB42C only), the firebox requires no
electricity making it ideal for emergency
back-up heat.
Blower Accessory
The FB36CA or FB42C fireboxes will accept the GA3700 accessory. 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
blower is optional.
Brick Liner
This firebox features a revolutionary lightweight concrete brick liner. As with all
concrete liners, this liner may develop slight
cracks when exposed to heat. These cracks
will not affect the performance of the fireplace or vent-free gas logs.
LOCATING
FIREBOX
Planning
Plan where you will install the firebox. This
will save time and money later when you
install the firebox. Before installation, consider the following:
1. Where the firebox will be located. Allow for wall and ceiling clearances (see
Installation Clearances, page 7).
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
WARNING: This firebox 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.
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, 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 fuelburning 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 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 retarder with
a rating of one perm (6 x 10
per pa-sec-m2) 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
From Outdoors
If your home does not meet all of the
three criteria above, proceed to page 5.
, page 6.
Ventilation Air
-11
kg
Confined and Unconfined Space
The National Fuel Gas Code (ANSIZ223.1,
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 FIREBOX 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 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:
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.
* 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 adjoin-
ing room or add ventilation grills between rooms. See Ventilation Air from Inside Building, page 6.
B. Vent room directly to the outdoors. See Ventilation Air from Outdoors, page 6.
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.
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 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
63,300 Btu/Hr (maximum the space can support)
79,000 Btu/Hr (actual amount of Btu/Hr used)
Example:
Gas water heater 40,000 Btu/Hr
Vent-free firebox
with log heater + 39,000 Btu/Hr
Total = 79,000 Btu/Hr
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 ventillation air by one of the methods described in the
National Fuel Gas Code, ANSI Z223.1, 1992, Section 5.3
103451
or applicable local codes.

WARRANTY INFORMATION
KEEP THIS WARRANTY
Model
Serial No.
Date Purchased
Always specify model and serial numbers when communicating with the factory.
We reserve the right to amend these specifications at any time without notice. The only warranty applicable is our
standard written warranty. We make no other warranty, expressed or implied.
LIMITED WARRANTY
VENT-FREE FIREBOX
DESA International warrants this product to be free from defects in materials and components for three (3) years from the
date of first purchase, provided that the product has been properly installed, operated and maintained in accordance with
all applicable instructions. To make a claim under this warranty the Bill of Sale or cancelled check must be presented.
This warranty is extended only to the original retail purchaser. This warranty covers the cost of part(s) required to restore
this heater to proper operating condition and an allowance for labor when provided by a DESA Authorized Service Center.
Warranty part(s) MUST be obtained through authorized dealers of this product and/or DESA International who will
provide original factory replacement parts. Failure to use original factory replacement parts voids this warranty. The heater
MUST be installed by a qualified installer in accordance with all local codes and instructions furnished with the unit.
This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that fail
or become damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by improper installation.
As with all concrete liners, this liner may develop slight cracks when exposed to heat. This cracking is considered normal.
Travel, diagnostic cost, labor, transportation and any and all such other costs related to repairing a defective heater will
be the responsibility of the owner.
TO THE FULL EXTENT ALLOWED BY THE LAW OF THE JURISDICTION THAT GOVERNS THE SALE OF THE
PRODUCT; THIS EXPRESS WARRANTY EXCLUDES ANY AND ALL OTHER EXPRESSED WARRANTIES
AND LIMITS THE DURATION OF ANY AND ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE TO THREE (3) YEARS ON ALL COMPONENTS FROM THE DATE OF FIRST PURCHASE; AND DESA INTERNATIONAL’S LIABILITY IS HEREBY
LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA INTERNATIONAL SHALL NOT BE
LIABLE FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES.
Some states do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation of incidental or
consequential damages, so the above limitation on implied warranties, or exclusion or limitation on damages may not apply
to you.
This warranty gives you specific legal rights, and you may also have other rights that vary from state to state.
