CHOOSING LOCATION FOR YOUR FIREBOX
Figure 1 shows some of many ways your firebox may be installed. Consider traffic pattern in your
room and location of doors and windows. Moving air from ceiling fans, open doors and hot air grills
may cause flames to impinge logs resulting in sooting. If a disturbance is found that affects flames, it
must be eliminated by turning off ceiling fan, closing door or closing hot air register. A corner
location may be best where space is limited.
Your Ventless Firebox Enclosure weighs no more than some of your fine furniture. If firebox is
located near a load bearing wall, additional supports to foundation will not be necessary. HEAVY
FACINGS, SUCH AS BRICK, STONE, ETC., MAY REQUIRE ADDITIONAL FOUNDATION
SUPPORT.
NOTE: WHEN FIREBOX IS INSTALLED DIRECTLY ON CARPETING, TILE OR OTHER
COMBUSTIBLE MATERIALS, OTHER THAN WOOD FLOORING, FIREBOX SHALL BE
INSTALLED ON A METAL OR WOOD PANEL EXTENDING FULL WIDTH AND DEPTH
OF ENCLOSURE.
GAS LINE
The gas supply line and electrical supply must be
installed before framing in fireplace by a licensed
installer. This appliance when installed, be electrically
grounded in accordance with local codes or in absence
of local codes, with National Electrical Code, ANSI \
NFPA 70.

UNCONFINED SPACE:
An unconfined space has a minimum air volume of 50 cubic feet for each 1,000 BTU/Hr (4.8m3per
Kw) input rating of all appliances in space (Cubic feet equals Length x Width x Height of space).
Include adjoining rooms only if there are doorless passageways or ventilation grills between rooms.
CONFINED SPACE:
“The National Fuel Gas Code defines unusually tight construction space as a space whose volume is
less than 50 cubic feet per 1,000 BTU per hour (4.8m3per KW) of the aggregate input rating of all
appliances installed in that space.
“WARNING: If the area in which heater may be operated is smaller than that defined as an
unconfined space, provide adequate combustion and ventilation air by one of methods
described in National Fuel Gas Code, ANSI Z223.1, 1992, Section 5.3”
NOTICE: Information on provisions for adequate combustion and ventilation air are located in
unvented room heater ‘s installation instructions. The unvented room heater’s instructions
must be followed exactly.
PRODUCING ADEQUATE VENTILATION
DETERMINING FRESH-AIR FLOW FOR
HEATER LOCATION
DETERMINE IF YOU HAVE UNUSUALLY TIGHT CONSTRUCTION OR UNCONFINED SPACE
Use this worksheet to determine if you have a confined or unconfined space.
SPACE: Include room in which you will install heater plus adjoining rooms with doorless
passageways or ventilation grills between rooms.
1. Determine the volume of space (length x width x height).
Length x Width x Height= ________ cu.ft. (volume of space)
EXAMPLE: 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) =
2560 cu. ft. (volume of space)
If additional ventilation to adjoining room is supplied with grills or openings, add volume of these
rooms to total volume of space.
2. Divide the space volume by 50 cubic feet to determine maximum BTU/Hr space
can support.
________ (volume of space) / 50 cu. ft = (maximum BTU/Hr space can support)
EXAMPLE: 2560 cu. ft. (volume of space) / 50 cu. ft. = 51.2 or
51200 (maximum BTU/Hr space can support.)

Page 14
3. Add the BTU/Hr of all fuel burning appliances in space.
Vent-Free Heater _________________________BTU/Hr.
Gas Water Heater* _________________________BTU/Hr.
Gas Furnace _________________________BTU/Hr.
Vented Gas Heater _________________________BTU/Hr.
Gas Fireplace Logs _________________________BTU/Hr.
Other Gas Appliance* +_________________________BTU/Hr.
Total = _________________________BTU/Hr.
Example: Gas water heater 40000 BTU/Hr.
Vent-free heater + 18000 BTU/Hr.
Total = 58000 BTU/Hr.
* Does not include direct-vent gas appliances. Direct-vent draws combustion
air from outdoors and vents to outdoors.
4. Compare the maximum BTU/Hr space can support with actual amount
of BTU/Hr used._____________BTU/Hr (maximum space can support)
_____________BTU/Hr (actual amount of BTU/Hr used)
Example: 51200 BTU/Hr (maximum space can support)
58000 BTU/Hr (actual amount of BTU/Hr used)
Space in above example is a confined space because actual BTU/Hr used is more than maximum
BTU/Hr the space can support. Additional fresh air must be provided. The following options are
available.
A. Rework worksheet, adding space of an adjoining room. If extra space provides an unconfined
space, remove door to adjoining room or add ventilation grills between rooms. See “Ventilation
Air From Inside Building”, page 15.
B. Vent room directly to outdoors. See “Ventilation Air From Outdoors” page 16.
C. Install a lower BTU/Hr heater, if lower BTU/Hr size makes room unconfined.
If actual BTU/Hr used is less than maximum BTU/Hr space can support, space is unconfined. You
will need no additional fresh air ventilation.
WARNING
YOU MUST PROVIDE ADDITIONAL VENTILATION AIR IN UNUSUALLY TIGHT
CONSTRUCTION.

Page 15
AIR FOR COMBUSTION AND VENTILATION
FROM INSIDE BUILDING
This fresh air would come from an adjoining unconfined space. When venting to an adjoining space,
you must provide two permanent openings: one within 12" of ceiling and one within 12" of floor on
wall connecting two spaces (see Options 1 and 2, Figure 6). You can also remove door into adjoining
room (see Option 3, Figure 6).
WARNING
REWORK WORKSHEET, ADDING SPACE OF ADJOINING UNCONFINED SPACE.
COMBINED SPACES MUST HAVE ADEQUATE AMOUNT AIR TO SUPPLY ALL
APPLIANCES IN BOTH SPACES.
NOTE: Each opening shall have a minimum free area of 1 square inch per 1000 BTU’s per
hour of total input ratings of all gas utilization equipment in confined space, but not less than
100 square inches.
Figure 6
Ventilation Air From Inside Building

Page 16
Figure 7 Ventilation Air From Outdoors
AIR FOR COMBUSTION AND VENTILATION
FROM OUTDOORS
Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent
openings: one within 12" of ceiling and one within 12" of floor. Connect these items directly to
outdoors. These spaces include attics and crawl spaces. Follow National Fuel Gas Code NFPA 54/
ANSI Z223.1, Section 4.3, “Air For Combustion and Ventilation” for required size of ventilation
grills or ducts.
IMPORTANT: Do not provide openings for inlet air into attic if attic has a thermostat-controlled
power vent. Heated air entering attic will activate power unit.

will need to follow these steps and diagram below and wiring diagram on page 18.
NOTE: The receptacle which is provided in Model ZCBB must be wired into your home (residence)
in order to have electricity to operate blower motor. If receptacle hasn’t been wired in during instal-
lation of ZCBB you may need to contact a licensed electrician. The Model ZCBB also has a thermo-
stat and wires and an ON/OFF switch standard on all units.
“WARNING: Any changes to this heater or its controls can be dangerous.”
A. First remove burner base and logs. Be sure to turn “OFF” gas supply before disconnecting sup-
ply line.
B. Remove (10) ten hex-head self-piercing screws that hold down the motor cover plate on inner
bottom of unit.
C. Locate (2) two wires that come down back of rear air channel from thermostat . Connect (1)
one of thermostat wires to top terminal on “ON/OFF” switch.
D. Connect black power cord wire to the 24" jumper wire provided, then attach jumper wire to mid-
dle terminal on “ON/OFF” switch. Next connect remaining thermostat wire to (1) of wires com-
ing from motor. Connect white power cord wire to white motor wire. The green power cord
wire should be screwed to motor bracket as ground wire. Place blower motor in cover plate
