PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National
Fuel Gas Code. NFPA 54/ANS Z223.1, Sec-
tion5.3,AirforCombustionandVentilation.
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-
termining Fresh-Air Flow For Appli-
ance Location , page 5.
Today’s homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
helpreduceheatlossinhomes.Homeowners
weatherstrip andcaulk aroundwindows and
doorstokeepthecoldairoutandthewarmair
in. During heating months, home owners
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
VENTILATION
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
unlessprovisions are provided for adequate
combustion and ventilation air.

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 propane/LP gas)
• manual shutoff valve
• 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.

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 a 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 18).
2. Replace the orifice(seeFigure18) with
the propane/LP pilot orifice with the
red stripe.
3. Replace and tighten the pilot line to the
bracket.
4. Continue with step 7 under Hearth Kit
Assembly and Installation, page 9.
Note: Followthe instructions under the sec-
tion, Testing Burner for Leaks, column 3.

IfyouareusingtheCGHRCremotecontrol
option, you must first connect the leads of
thereceiver to theterminal block onthe gas
control (see Figure 19).
1. Connect the leads to the male fast-on
terminals marked TH and TPTH.
2. Install a 9Vbattery(referto the instruc-
tions included with the CGHRC).
3. Install a 9V battery into the hand-held
transmitter.
4. Insert the receiver into the simulated
log control cover, with the raised cyl-
inder fitting into the hole in the cover.

Control
Valve
No Optional Accessories
If you choose no remote accessories at this
time, the provided jumper wire must be
installed to the terminal block on the gas
control. Connect the lead to the fast-on
terminals marked TH and TPTH.
TESTING BURNER FOR
LEAKS
1. Generously apply soapy solution to all
connections.
WARNING: Never check for
gas leaks with open flame.
2. Light the burner with the shut-off valve
no more than half open and holding a
match slightly in front of the pan (see
Lighting Instructions, page 13).
3. Inspect all connectionsforbubbles,raw
gas odor, or flame from any area other
than the burner (leaks). If leaks are de-
tected, shut off the gas valve immedi-
ately. Tighten, or reassemble the loose
connection(s) using pipe joint com-
pound until burner system is leak free.
4. When the burner is tested and leak free,
observe the individual tongues of flame
on the burner. Note: The burner design
includesmore ports onthe outside ofthe
bar. Make sure that all ports are clear
and producing flame evenly across the
burner.Ifanyportsappearblocked,clear
them by removing the burner manifold
and reaming the ports with a modified
paper clip or other suitable tool.
5. When finishedtesting,turn the gasshut-
off valve OFF to extinguish all flames.
