This heater 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 glowing coals. This
heater is designed for vent-free operation
with flue damper closed. It has been tested
and approved to ANSI Z21.11.2 standard for
unvented heaters.
PRODUCT FEATURES
SAFETY DEVICE
This heater has a pilot with an Oxygen Deple-
tion Sensing (ODS) safety shutoff system. The
ODS/pilot is a required feature for vent-free
room heaters. The ODS/pilot shuts off the
heater if there is not enough fresh air.
ELECTRONIC IGNITION SYSTEM
This heater has an electronic ignitor to light
heater fuel supply.
AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall
notbeinstalledinaroomorspace
unless the required volume of
indoorcombustionairisprovided
by the method described in the
National Fuel Gas Code, ANSI
Z223.1/NFPA54,theInternational
Fuel Gas Code, or applicable
local codes. Read the following
instructionstoinsureproperfresh
airfor thisandother fuel-burning
appliances in your home.
Today’s homes are built more energy efficient
than ever. New materials, increased insulation
and new construction methods help reduce
heat loss in homes. Home owners weather
strip and caulk around windows and doors to
keep the cold air out and the warm air in. Dur-
ing heating months, home owners 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, fireplaces, clothes dryers and
fuel burning appliances draw air from the house
to operate. You must provide adequate fresh
air for these appliances. This will insure proper
venting of vented fuel-burning appliances.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from NationalFuel
Gas Code, ANSI 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 6 through 8 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 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 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 8.
If your home does not meet all of the three
criteria above, proceed to DeterminingFresh-
Air Flow For Heater Location, page 7.

AIR FOR COMBUSTION AND VENTILATION
Continued
Confined and Unconfined Space
The National Fuel Gas Code, ANSI Z223.1/
NFPA54 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 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/hr (4.8 m3per kw) of the ag-
gregate 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 un-
confined space.
* 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
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 door-
less 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. Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example: 2560 cu. ft. (volume of space) x 20
= 51,200 (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.
Example:
Gas water heater __________ Btu/Hr
Vent-free fireplace + _________ 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 used)
Example: 51,200 Btu/Hr (maximum the
space can support)
73,000 Btu/Hr (actual amount of
Btu/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 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
an unconfined space, remove door to adjoin-
ing room or add ventilation grills between
rooms. See Ventilation Air From Inside
Building, page 8.
B. Vent room directly to the outdoors. See
Ventilation 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 maxi-
mum Btu/Hr the space can support, the space is
an unconfined space. You will need no additional
fresh air ventilation.

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
and one within 12" of the floor. 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.

ers. This could damage heater.
Only handle base assembly by
grates.
IMPORTANT: Make sure the heater burners
are level.
Installation Items Needed
• hardware package (provided with heater)
• approved flexible gas hose and fittings
provided (if allowed by local codes)
• sealant (resistant to propane/LP gas, not
provided)
• electric drill with 3/16” masonry drill bit
Note: Install optional MRC Series receiver
and hand-held remote control kit (see Ac-
cessories, page 39) before installing gas log
heater. See installation instructions included
with the kit.
1. Apply pipe joint sealant lightly to male
threads of the 3/8 NPT side of gas fitting
elbow (provided) and connect to inlet
side of gas control. Remove gas fitting
from flexible gas hose (provided) before
connecting to elbow (see Figure 10).
2. Position heater base assembly in fire-
place.

CONNECTING TO GAS SUPPLY
WARNING: This appliance
requires a 3/8" NPT (National
PipeThread)inletconnectionto
the pressure regulator.
WARNING:Aqualifiedservice
person must connect heater to
gassupply.Followalllocalcodes.
CAUTION: Never connect
propane/LP fireplace directly
to the propane/LP supply. This
heaterrequiresanexternalregu-
lator (not supplied). Install the
external regulator between the
heater and propane/LP supply.
WARNING: Never connect
natural gas fireplace to private
(non-utility) gas wells. This
gas is commonly known as
wellhead gas.
Installation Items Needed
Before installing heater, make sure you have
the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas connec-
tor (if allowed by local codes) (not provided)
* An equipment shutoff valve with 1/8" NPT
tap is an acceptable alternative to test gauge
connection. Purchase the optional equipment
shutoff valve from your dealer.
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 re-
duce incoming gas pressure, heater regulator
damage could occur. Install external regulator
with the vent pointing down as shown in Figure
12, page 14. Pointing the vent down protects
it from freezing rain or sleet.
CAUTION: Use only new,
black iron or steel pipe. In-
ternally-tinned copper tubing
may be used in certain areas.
Check your local codes. Use
pipe of 1/2" diameter or greater
to allow proper gas volume to
heater.Ifpipeistoosmall,undue
loss of volume will occur.
Installation must include an equipment 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 heater (see
Figure 13, page 14).
IMPORTANT: Install equipment shutoff valve
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
threads. This will prevent excess sealant from
going into pipe. Excess sealant in pipe could
result in clogged heater valves.
WARNING: Use pipe joint
sealantthatisresistanttoliquid
petroleum (LP) gas.

We recommend that you install a sediment
trap 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 traps moisture and contami-
nants. This keeps them from going into heater
controls. If sediment trap is not installed or is
installed wrong, heater may not run properly.
CAUTION: Avoid damage to
gas control. Hold gas control
with wrench when connecting
it to gas piping and/or fittings.
CHECKING GAS CONNECTIONS
WARNING:Testallgaspiping
and connections, internal and
external to unit, for leaks after
installing or servicing. Correct
all leaks at once.
* Purchase the optional equipment shutoff
valve from your dealer.
**Minimum inlet pressure for purpose of input
adjustment.
