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.
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
Confined Space 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 heater shall not be installed in a con-
fined space or unusually tight construction
unlessprovisions areprovided foradequate
combustion and ventilation air.

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 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 win-
dow 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 of the three
criteria above, you must provide ad-
ditional fresh air. See Ventilation Air

PRODUCT
FEATURES
OPERATION
This vent-free fireplace is clean burning. It
requires no outside venting. There is no heat
loss out a vent or up a chimney. Heat is
generated by both realistic flames and glow-
ingembers.Thefireplacerequiresnoelectric-
itymakingitidealforemergencybackupheat.
SAFETY FEATURES
This fireplace has a pilot with an Oxygen
Depletion Sensor Shutoff System (ODS).
TheODS/pilotisarequiredfeatureforvent-
freeroomheaters.TheODSsystemprotects
against oxygen depletion and any interrup-
tion in the fuel supply. If either occurs, the
ODS shuts off gas flow to the burner, turn-
ing the fireplace off. An internal regulator
controls fluctuations in your gas pressure.
PIEZO IGNITION SYSTEM
This fireplace has a piezo ignitor. This sys-
tem requires no matches, batteries, or other
sources to light fireplace.
THERMOSTAT CONTROL
MODELS (CGFP28PT)
These fireplaces have a thermostat sensing
bulb and a control valve. The thermostat
controls the heat output and flame height.
This maintains a consistent room tempera-
ture. Even the lowest setting provides real-
istic flames and glowing embers from two
burners. Selecting higher comfort settings
allows fireplace to run longer, producing
greater heat output. At lower comfort set-
tings,thefireplacewillrunless.Thisresults
in increased heating comfort. This can also
result in lower gas bills. An optional ther-
mostatically (GA3650T) or manually
(GA3750) controlled blower is available
(see Accessories, page 32).
VARIABLE MANUAL
CONTROL (CGFP28P)
These fireplaces have a variable manual con-
trol valve which allows the user to choose the
heat setting that best suits his needs. Any
settingbetweenlowand highmaybeselected
by simply turning the control knob. An op-
tional manually controlled blower (GA3750)
is available (see Accessories, page 32).

DETERMINING FRESH-AIR FLOW FOR FIREPLACE 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 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 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. 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: 3168 cu. ft. (volume of space) ÷50 cu. ft. = 63.3 or 63,300 (maximum Btu/Hr the space can support)
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.
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: 63,300 Btu/Hr (maximum the space can support)
68,000 Btu/Hr (actual amount of Btu/Hr used)
ThespaceintheaboveexampleisaconfinedspacebecausetheactualBtu/HrusedismorethanthemaximumBtu/Hrthespacecansupport.
You must provide additional fresh air. Your options are as follows:
A. Rework work sheet, 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 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 unconfined space. You will need no
additional fresh air ventilation.
WARNING:Iftheareainwhichtheheatermaybeoperatedissmallerthanthatdefinedasanunconfinedspace
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, 1992, Section 5.3 or applicable local codes.
Example:

Installation Items Needed
Before installing fireplace, make sure you
have the items listed below.
• external regulator (supplied by installer,
see Figure 30)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• manual shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas con-
nector (if allowed by local codes) (not
provided)
* AnA.G.A.design-certifiedmanualshutoff
valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Pur-
chase the optional A.G.A. design-certified
manual shutoff valve from your dealer. See
Accessories, page 32.
The installer must supply an external regu-
lator. The external regulator will reduce
incoming gas pressure. You must reduce
incominggaspressuretobetween11and14
inchesofwater.Ifyoudonotreduceincom-
ing gas pressure, heater regulator damage
could occur. Install external regulator with
the vent pointing down as shown in Figure

The variable control valve can be set to
any heat setting and flame height de-
sired,bysimplyturningthecontrolknob
