IMPORTANT SAFETY INFORMATION
WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An unvented room heater produces
approximately one (1) ounce (30 mL) of water for every 1,000 BTUs (.3KW) of gas
input per hour. Unvented room heaters are recommended as supplemental heat (a
room) rather than a primary heat source (an entire house). In most supplemental heat
applications, the water vapor does not create a problem. In most applications, the water
vapor enhances the low humidity atmosphere experienced during cold weather.
The following steps will help insure that water vapor does not become a problem:
1. Be sure the heater is sized properly for the application, including ample combustion
air and circulation air.
2. Ifhighhumidityisexperienced,adehumidiermaybeusedtohelplowerthewater
vapor content of the air.
3. Do not use an unvented room heater as the primary heat source.
PRODUCING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code. NFPA 54/ANS Z223.1. Air
for Combustion and Ventilation. All spaces in homes fall into one of the three following
ventilationclassications:
1. Unusually Tight Construction
2. UnconnedSpace
3. ConnedSpace
The information on pages 7 through 9 will help you classify your space and provide
adequate ventilation.
Conned and Unconned Space
TheNationalFuelGasCode,ANSZ223.1denesaconnedspaceasaspacewhose
volume is less than 50 cu. ft. per 1,000 BTU/hr (4.8 m^3 per kw) of the aggregate input

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have a Conned or Unconned Space
Use this worksheet to determine if you have a conned or unconned 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 × Width × Height = cu. ft. (volume of space)
Example: Space size 20 ft. (length) × 16 ft. (width)× 8 ft. (ceiling height)= 2560 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)
3. Add the BTU/hr of all fuel burning appliances in the space.

outdoors and vents to the outdoors.
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 dened as construction where:
walls and ceilings exposed to the outside atmosphere have a continuous water vapor
retarder with a rating of one perm (6×10-11kg per pa-sec-m2) or less with openings
gasketed or sealed and
Weather stripping has been added on openable windows and on doors and
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”. If your home does not meet all of the three
criteria above, proceed to “Determining Fresh-Air Flow For Heater Location”.

Ventilation Air From Inside Building
This fresh air would come from adjoining un-
conned space. When ventilating to an adjoin-
ing unconned space, you must provide two
permanent openings: one within 12 inches of
the wall connecting the two spaces (see op-
tions 1 and 2, Figure 1). You can also remove
door into adjoining room (see option 3, Figure
2). Follow the National Fuel Gas Code NFPA
54/ANS Z223.1. Air for Combustion and Ven-
tilation for required size of ventilation grills or
ducts.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills
or duct. You must provide two permanent
openings: one within 12 inches of the
ceiling and one within 12 inches of the oor
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 NFPA 54/ANS Z223.1,.
Air for Combustion and Ventilation
for required size of ventilation grills or ducts.
The space in the above example is a conned 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:
Rework worksheet, adding the space of an adjoining room. If the extra space
provides an unconned space, remove door to adjoining room or add ventilation grills
between rooms. See “Ventilation Air From Inside Building”,page 9.
Vent room directly to the outdoors. See “Ventilation Air From Outdoors”, page 9.
Install a lower BTU/hr heater, 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 unconned space. You will need no additional fresh air ventilation.
NOTE: If the area in which the heater may be operated is smaller than that dened
as an unconned 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, ANS Z223.1/NFPA. Air for combustion and ventilation or
applicable local codes.

IMPORTANT: Vent-free heaters add moisture to the air. Although this is benecial,
installing heater in rooms without enough ventilation air may cause mildew to form
from too much moisture. See Air for Combustion and Ventilation, pages 8 through 10.
CHECK GAS TYPE
Make sure your gas supply is correct for your log set. If supply is not correct, do not install
heater. Call dealer where you purchased heater for proper gas log set.
Minimum Fireplace Clearance to Combustible Materials
Log size Side wall Ceiling
18 in., 24 in., 30 in. 16 in. 42 in.
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. 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.
INSTALLATION
NOTICE: This heater is intended for use as supplemental heat. Use this heater along
with your primary heating system. Do not install this heater as your primary heat
source. If you have a central heating system you may run the system’s circulating
blower while using the heater. This will help circulate the heat throughout the house.
In the event of power outage, you can use this heater as your primary heat source.
WARNING: A qualied technician must install heater. Follow all local codes.
WARNING: Before installing in a solid flue burning firebox, the chimney flue and
firebox must be cleaned of soot, creosote, ashes and loose paint by a qualified
chimney cleaner. Creosote will ignite if highly heated. A dirty chimney ue may create
and distribute soot within the house. Inspect chimney ue for damage.
WARNING: Maintain the minimum clearances. If possible, provide greater clearances
from the oor, ceiling, and adjoining wall than required.
WARNING: Seal any fresh air vents or ash clean-out doors located on the oor or
wall of replace to prevent drafting caused by pilot outage or sooting. Use a heat-
resistant sealant. Do not seal chimney ue damper.
CAUTION: This heater creates warm air currents. These currents move heat to
wall surface next to heater. Installing heater next to vinyl or cloth wall coverings
or operating heater where impurities (such as tobacco smoke, aromatic candles,
cleaning uids, oil or kerosene lamps, etc.) in the air exist may discolor walls.
NOTICE: State or local codes may only allow operation of this appliance in a vented
conguration. Check your state or local codes.
