SAFETY
Carbon Monoxide Poisoning: Early signs
of carbon monoxide poisoning resemble the
flu, with headaches, dizziness or nausea. If
you have these signs, the fireplace may not
be working properly. Get fresh air at once!
Have fireplace serviced. Some people are
more affected by carbon monoxide than oth-
ers. These include pregnant women, people
with heart or lung disease or anemia, those
under the influence of alcohol and those at
high altitudes.
Natural and Propane/LP Gas: Natural and
propane/LP gases are odorless. An odor-
making agent is added to the gas. The odor
helps you detect a gas leak. However, the
odor added to the gas can fade. Gas may be
present even though no odor exists.
Make certain you read and understand all
warnings. Keep this manual for reference. It
is your guide to safe and proper operation of
this fireplace.

AIR FOR COMBUSTION AND VENTILATION
Today’shomesarebuiltmoreenergyefficient
thanever.Newmaterials,increased insulation
and new construction methods help reduce
heat loss in homes. Homeowners apply
weather strip and caulk around windows and
doorstokeepthe cold airoutandthe warm air
in.Duringheatingmonths,homeownerswant
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 ap-
pliancesneedfreshairforpropercombustion
and ventilation.
Exhaust fans, some fireplaces, clothes dryers
and some fuel-burning appliances draw air
from the house to operate. You must provide
adequate fresh air for these appliances. This
will ensure proper venting of vented fuel-
burning appliances.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National
Fuel Gas Code ANS Z223.1/NFPA 54,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 7 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 un-
usually tight construction, you must provide
additional fresh air.
Unusually tight construction is defined as
construction where:
a. walls and ceilings exposed to the out-
side atmosphere have a continuous
water vaporretarder witha rating ofone
perm (6 x 10-11 kg 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 Ventilation Air From Outdoors,
Page 9.
If your home does not meet all of the three
criteria above, proceed to Determining
Fresh-Air Flow for Firebox Location,
Page 8.
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/
NFPA54 allows two methods for determining
whetherthespace inwhichtheheaterisbeing
installedisconfinedorunconfinedspace.The
standardmethod
definesaconfinedspace as
a space whose volume is less than 50 cubic
feetper1,000Btu/hr (4.8 m3perkw)oftheag-
gregateinputratingofallappliancesinstalled
in that space and an unconfined space as
a space whose volume is not less than 50
cubic feet per 1,000 Btu/hr (4.8 m3per kw) of
the aggregate input rating of all appliances
installedinthatspace. Roomscommunicating
directlywiththespace inwhichtheappliances
areinstalled*,throughopeningsnot furnished
with doors, are considered a part of the un-
confined space.
This appliance shall not be installed in a
confinedspaceor unusually tightconstruction
unless provisions are provided for adequate
combustion and ventilation air.
Where the air infiltration rate of a structure is
known,theKnownAirInfiltrationRate Method
may be used. Follow The National Fuel Gas
Code, ANSI Z223.1/NFPA 54 to use this
method to determine if the space is confined
or unconfined.
* Adjoining rooms are communicating only if
therearedoorlesspassageways orventilation
grills between them.
WARNING: This appliance shall
not be installed in a room or space
unless the required volume of indoor
combustion air is provided by the
method described in the National
Fuel Gas Code, ANSI Z223.1/NFPA
54, the International Fuel Gas Code,
or applicable local codes. Read the
following instructions to ensure
properfresh airfor thisand otherfuel-
burning appliances in your home.

DETERMINING FRESH-AIR FLOW
FOR FIREBOX LOCATION
Determining if You Have a Confined or
Unconfined Space Using the Standard
Method
Use this work sheet to determine if you have
a confined or unconfined space.
Space: Includes the room in which you will
install appliance plus any adjoining rooms
withdoorlesspassageways orventilationgrills
between the rooms.
1. Determine the volume of the space (length
x width x height).
Length xWidthx 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. Multiplythespacevolumeby20 todetermine
themaximumBtu/Hr thespacecan support.
________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example:3168 cu. ft. (volume of space) x
20=63,360(maximumBtu/Hrthespacecan
support)
3. Add the Btu/Hr of all fuel burning appliances
in the space.
Gas water appliance* __________Btu/Hr
Gas furnace __________Btu/Hr
Vented gas appliance __________Btu/Hr
Gas fireplace logs __________Btu/Hr
Other gas appliances* + _________Btu/Hr
Total = _________Btu/Hr
* Do not include direct-vent gas appliances.
Direct-vent draws combustion air from the
outdoors and vents to the outdoors.
Example:
Gas water appliance __________Btu/Hr
Gas firebox logs + _________Btu/Hr
Total = _________Btu/Hr
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:35,840 Btu/Hr (maximum the
space can support)
40,000 Btu/Hr (actual amount of
Btu/Hr used)
Thespaceintheabove example is aconfined
spacebecausetheactual Btu/Hrusedismore
thanthemaximumBtu/Hrthespacecansup-
port. 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 appliance, if
lowerBtu/Hrsizemakesroom 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 appliance may be operated does
not meet the required volume for
indoor combustion air, combustion
and ventilation air shall be provided
by one of the methods described in
the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, the International
Fuel Gas Code, or applicable local
codes.

Astria.us.com
126882-01B 9
AIR FOR COMBUSTION AND VENTILATION
Continued
The space in the previous example is a confined
space because the actual Btu/Hr used is more
than the maximum Btu/Hr the space can sup-
port. 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
anunconfinedspace,removedoorto adjoin-
ing room or add ventilation grills between
rooms. See Ventilation Air From Inside
Building.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors.
C. Install a lower Btu/Hr fireplace, if lower Btu/
Hr size makes room unconfined.
If the actual Btu/Hr used is less than the maxi-
mum Btu/Hr the space can support, the space is
anunconfinedspace.Youwillneed noadditional

VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining
unconfined space. When ventilating to an
adjoiningunconfinedspace, youmustprovide
twopermanentopenings: onewithin12"of the
ceiling and one within 12" of the floor on the
wall connecting the two spaces (see options
1 and 2, Figure 4). You can also remove door
into adjoining room (see option 3, Figure 4).
Follow the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Air for Combustion and
Ventilation for required size of ventilation
grills or ducts.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation
grills or ducts. You must provide two perma-
nent openings: one within 12" of the ceiling
andonewithin12"ofthefloor. 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, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation for required size
of ventilation grills or ducts.
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.
