PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National
FuelGasCode.NFPA54/ANSZ223.1,Sec-
tion 5.3, Air for Combustion and Ventila-
tion.
Allspacesinhomesfallintooneofthethree
following ventilation classifications:
1. Unusually Tight Construction
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 win-
dows 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-
fined as construction where:
a. walls and ceilings exposed to the
outside atmosphere have a con-
tinuous water vapor retarder with
a rating of one perm (6x10-11 kg
per pa-sec-m2) or less with open-
ings 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, be-
tween sole plates and floors,be-
tween wall-ceiling joints, be-
tween wall panels, at penetra-
tionsforplumbing,electrical,and
gas lines, and at other openings.
If your home meets all of the three
criteria above, you must provide ad-
ditional fresh air. See Ventilation Air
From Outdoors , page 6.
If your home does not meet all of the
three criteria above, proceed to De-
terminingFresh-AirFlowForLogSet
Location , page 5.
Today’s homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
helpreduceheatlossinhomes.Homeowners

want their homes as airtight as possible.
While it is good to make your home energy
efficient,yourhomeneedstobreathe.Fresh
air must enter your home. All fuel-burning
appliances need fresh air for proper com-
bustion and ventilation.
Exhaustfans,fireplaces,clothesdryers,and
fuel burning appliances draw air from the
house to operate. You must provide ad-
equate fresh air for these appliances. This
will insure proper venting of vented fuel-
burning appliances.
AIR FOR
COMBUSTION AND

WARNING: This appliance
shall not be installed in a con-
fined space or unusually tight
construction unless provisions
are provided for adequate com-
bustion and ventilation air. Read
the following instructions to in-
sure proper fresh air for this and
other fuel-burning appliances in
your home.
Confined and Unconfined Space
The National Fuel Gas Code (ANS Z223.1,
1992 Section 5.3) defines a confined space
as a space whose volume is less than 50
cubicfeetper1,000Btuperhour(4.8m3per
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 m3per kw) of the aggregate
inputratingofallappliancesinstalledinthat
space.Rooms communicatingdirectlywith
the space in which the appliances are in-
stalled*, through openings not furnished
with doors, are considered a part of the
unconfined space.
This log set shall not be installed in a con-
fined space or unusually tight construction

OWNER’S MANUAL
DETERMINING FRESH-AIR FLOW FOR APPLIANCE 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 appliance 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)
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: 2560 cu. ft. (volume of space) ÷50 cu. ft. = 51.2 or 51,200 (maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel burning appliances in the space.
Gas fireplace logs _____________ Btu/Hr
Gas water heater* _____________ Btu/Hr
Gas furnace _____________ Btu/Hr
Vented gas heater _____________ Btu/Hr
Vent-free heater _____________ 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.
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: 51,200 Btu/Hr (maximum the space can support)
95,000 Btu/Hr (actual amount of Btu/Hr used)
ThespaceintheaboveexampleisaconfinedspacebecausetheactualBtu/HrusedismorethanthemaximumBtu/Hrthespacecansupport.
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 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 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 unconfined space. You will need no
additional fresh air ventilation.

Installation Items Needed
Before installing log set, make sure you
have the items listed below.
• piping (check local codes)
• sealant (resistant to LP gas)
• manual shutoff valve
• test gauge connection
• adjustable (crescent) wrench or pliers
• sediment trap
• tee joint
• pipe wrench
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
yourlocalcodes.Usepipeof1/2"
diameter or greater to allow
proper gas volume to log set. If
pipe is too small, undue loss of
pressure will occur.
Installsedimenttrapinsupplylineasshown
inFigure 6.Locate sedimenttrapwhere itis
within reach for cleaning. Locate sediment
trap where trapped matter is not likely to
freeze. A sediment trap traps moisture and
contaminants. This keeps them from going
into log set controls. If sediment trap is not
installed or is installed wrong, log set may
not run properly.
Installation must include a manual shutoff
valve, union, and plugged 1/8" NPT tap.
Locate NPT tap within reach for test gauge
hook up. NPT tap must be upstream from
log set (see Figure 6).
Apply pipe joint sealant lightly to male
threads. This will prevent excess sealant
fromgoing into pipe. Excess sealant inpipe
could result in a clogged burner injector.

Propane/LP Gas Conversion
To convert to propane/LP gas, the burner
inlet fitting and pilot orifice must be re-
placed.Thepropane/LPburnerinletfittingis
supplied with the orifice installed for a 24"
log set. If you have an 18" or 30" set, you
must change this orifice also. See Figure 1,
page 3 for product identification.
Burner Inlet Fitting
1. Removetheburnerinlet fittingfrom the
burner pan assembly. DO NOT remove
the orifice from this fitting. The pro-
pane/LP burner inlet fitting is included
in the hardware kit (see Figure 15).

Changing Pilot Orifice
The pilot is provided with a natural gas
orifice installed. For propane/LP gas you
must remove it and replace it with an pro-
pane/LP orifice. The hardware kit contains
an propane/LP orifice with a red stripe for
converting the pilot.
1. Gently loosen and remove the pilot
line connection from the bracket (see
Figure 17, page 11).
2. Be sureto use thecorrect orificeforyour
appliance. The hardware kit included
withthis appliance containstwo orifices
with a cone-like shape. If you have an
18" set, the orifice for the burner inlet
fitting is red; for a 30" set, it is black. If
you have a 24" log set, the orifice is al-
ready installed inside the fitting.
3. For an 18" or 30" set, use a 10mm
socket or nut driver to remove the ori-
fice from the propane/LP burner inlet
fitting. Choose the correct orifice for
your log set size and install in place of
the orifice you just removed.
4. Using thread sealant (resistant to the
actionofpropane/LPgas)onlargerend
of fitting, screw the burner inlet fitting
through hole and into burner manifold.
Tighten using a wrench.
5 . Follow steps 1 through 12 under Natu-
ral Gas Installation, pages 9 and 10.
