AIR FOR COMBUSTION AND VENTILATION
Today’s homes are built more energy efficient
than ever. New materials, increased insulation
andnewconstructionmethods help reduce heat
lossinhomes.Homeownersapply weather strip
and caulk around windows and doors to keep
thecoldairoutandthewarmairin.Duringheat-
ing months, homeowners 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 ap-
pliances need fresh air for proper combustion
and ventilation.
Exhaust fans, some fireplaces, clothes dryers
and some fuel-burning appliances draw air from
thehouse tooperate.You mustprovideadequate
fresh air for these appliances. This will ensure
properventing ofventedfuel-burning appliances.
PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel
Gas Code, ANSI Z223.1/NFPA54, Air for Com-
bustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classifications:
WARNING: This heater 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 en-
sure proper fresh air for this and other
fuel-burning appliances in your home.
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
TheinformationonPages 6-8 willhelp you clas-
sifyyourspaceandprovideadequateventilation.
Unusually Tight Construction
The air that leaks around doors and windows
mayprovideenoughfreshair forcombustionand
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 10-11 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 plumb-
ing, electrical and gas lines and at other
openings.
If your home meets all three criteria above,
you must provide additional fresh air. See
Ventilation Air From Outdoors, Page 8.
If your home does not meet all three criteria
above, proceed to Determining Fresh-Air
Flow For Heater Location, below.
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/
NFPA54 allows two methods for determining
whether the space in which the heater is being
fire-parts.com

Astria.us.com
126810-01B 7
AIR FOR COMBUSTION AND VENTILATION
Continued
installed is confined or unconfined space. The
standard method defines a confined space as
a space whose volume is less than 50 cubic
feet per 1,000 Btu/hr (4.8 m3per kw) of the ag-
gregate 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/hr (4.8 m3per 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.
Where the air infiltration rate of a structure is
known, the Known Air Infiltration Rate Method
may be used. Follow The National Fuel Gas
Code,ANSI Z223.1/NFPA54 tousethismethod
to determine if the space is confined or uncon-
fined.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation
grills between them.
DETERMINING FRESH-AIR FLOW FOR
HEATER 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
fireplace 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 20 ft. (length) x 16 ft.
(width) x 8 ft. (ceiling height) = 2560 cu. ft.
(volume of space)
Ifadditional ventilationto adjoiningroom issup-
plied with grills or openings, add the volume of
these rooms to the total volume of the space.
2. Multiplythespacevolumeby20todetermine the
maximum Btu/Hr the space can support.
________ (volumeofspace)x20=(Maximum
Btu/Hr the space can support)
Example: 2560 cu. ft. (volume of space) x 20 =
51,200 (maximum Btu/Hr the space can sup-
port)
3. Add the Btu/Hr of all fuel burning appliances in
the space.
Vent-free fireplace __________Btu/Hr
Gas water heater* __________Btu/Hr
Gas furnace __________Btu/Hr
Vented gas heater __________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 heater __________Btu/Hr
Vent-free fireplace + _________Btu/Hr
Total = _________Btu/Hr
4.
Comparethe maximumBtu/Hr thespacecan sup-
port with the actual amount of Btu/Hr used.
_______ Btu/Hr (maximum can support)
_______ Btu/Hr (actual amount used)
Example:51,200 Btu/Hr (maximum the space
can support)
73,000Btu/Hr(actual amountofBtu/
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
roomoraddventilationgrillsbetweenrooms.See
Ventilation Air From Inside Building, Page 8.
B. Vent roomdirectly tothe outdoors.See Ventila-
tion Air From Outdoors, Page 8.
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 maximum
Btu/Hr the space can support, the space is an un-
confined space. You will need no additional fresh
air ventilation.
40,000
33,000
73,000
WARNING: If the area in which the
appliance may be operated does not
meet the required volume for indoor
combustion air, combustion and ven-
tilation 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 ap-
plicable local codes.

is more than 12", you may need the hood ac-
cessorytodeflect heatawayfrom your mantel
shelf. See Figure 5 and Figures 6 and 7,
Page 11, for minimum clearances.
IMPORTANT:If you cannot meet these
minimum clearances, you must operate
heater with chimney flue damper open. Go
to Installing Damper Clamp Accessory for
Vented Operation, Page 13.
MANTEL CLEARANCES
In addition to meeting noncombustible mate-
rial clearances, you must also meet required
clearances between fireplace opening and
mantelshelf. Ifyoudo notmeettheclearances
listed below, you will need a hood.
Determining Minimum Mantel Clearance
If you meet minimum clearance between
mantel shelf and top of fireplace opening, a
hood is not required (see Figure 6).
Determining Minimum Mantel Clearance
When Using a Hood
If minimum clearances in Figure 6, are not
met, you must have a hood. When using a
hood there are still certain minimum mantel
clearances required. Follow minimum clear-
ances shown in Figure 7, when using hood.

INSTALLING DAMPER CLAMP
ACCESSORY FOR VENTED
OPERATION
NOTE: When used as a vented heater, ap-
pliance must be installed only in a solid-fuel
burningfireplacewithaworkingflueandcon-
structed of noncombustible material.
For Massachusetts Residents Only: Instal-
lationofthisgas log setasaventedappliance
in the Commonwealth of Massachusetts re-
quires the damper be permanently removed
or welded in the fully open position.
If your heater is a non-thermostatically-
controlled model, you may use this heater as
a vented product. There are three reasons
for operating your heater in the vented mode.
1. Thefireplacedoes notmeetthe clearance
to combustibles requirements for vent-
free operation.
2. State or local codes do not permit vent-
free operation.
3. You prefer vented operation.
If reasons number 1 or 2 above apply to you,
you must permanently open chimney flue
damper. You must install the damper clamp
accessory (to order, see Accessories, Page
29). This will ensure vented operation (see
Figure 10). The damper clamp will keep
damper open. Installation instructions are
included with clamp accessory.
See chart below for minimum permanent flue
opening you must provide. Attach damper
clamp so the minimum permanent flue open-
ing will be maintained at all times.

tor (if allowed by local codes) (provided)
For propane/LP units, the installer must
supply an external regulator. The external
regulator will reduce incoming gas pressure.
You must reduce incoming gas pressure to
between 11" and 14" of water. If you do not
reduceincominggas pressure, heater regula-
tordamagecouldoccur. Installexternalregu-
lator with the vent pointing down as shown in
Figure 12. Pointing the vent down protects it
from freezing rain or sleet.

NPT tap must be upstream from heater (see
Figure 13).
IMPORTANT:Install equipment shutoffvalve
in an accessible location. The equipment
shutoff valve is for turning on or shutting off
the gas to the appliance.
Check your building codes for any special
requirements for locating equipment shutoff
valve to fireplaces.
Apply pipe joint sealant lightly to male NPT

with wrench when connecting
it to gas piping and/or fittings.
WARNING:Testallgaspiping
and connections, internal and
external to unit, for leaks after
installing or servicing. Correct
all leaks at once.
WARNING: Never use an
open flame to check for a leak.
Applyanoncorrosiveleakdetec-
tion fluid to all joints. Bubbles
forming show a leak. Correct all
leaks at once.
CAUTION: Make sure exter-
nal regulator has been installed
between propane/LP supply
and appliance. See guidelines
under Connecting to Gas Sup-
ply, Page 14.
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of
1/2"diameterorgreatertoallow
proper gas volume to heater. If
pipe is too small, undue loss of
volume will occur.
We recommend that you install a sediment
trap (not supplied with log set) in supply line
as shown in Figure 13. Locate sediment trap
where it is within reach for cleaning. Install
in piping system between fuel supply and
heater. Locate sediment trap where trapped
matter is not likely to freeze. A sediment trap
captures moisture and contaminants. This
keeps them from going into heater controls.
If sediment trap is not installed or is installed
wrong, heater may not run properly.
