OPERATION
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 ames and glowing coals. This
heater is designed for vent-free operation
with ue damper closed. It has been tested
and approved to ANSI Z21.11.2 standard for unvented heaters. State and local codes in some areas prohibit the use of vent-free heat­ers. This heater may also be operated as a vented decorative (ANSI Z21.60) product by
opening the ue damper.
PRODUCT FEATURES
SAFETY DEVICE
This heater has a pilot with an Oxygen Deple­tion 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
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 insure proper fresh air for this and other fuel-burning appliances in your home.
Today’s homes are built more energy efcient 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
efcient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning ap­pliances need fresh air for proper combustion and ventilation.
Exhaust fans, replaces, 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 National Fuel Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned 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 un­usually tight construction, you must provide
additional fresh air.
Unusually tight construction is dened 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 oors, 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 Determining Fresh­Air Flow For Heater Location, page 7.

AIR FOR COMBUSTION AND VENTILATION
Continued
Conned and Unconned Space
The National Fuel Gas Code, ANSI Z223.1/ NFPA 54 denes a conned space as a space
whose volume is less than 50 cubic feet per
1,000 Btu/hr (4.8 m3 per kw) of the aggregate
input rating of all appliances installed in that
space and an unconned space as a space
whose volume is not less than 50 cubic feet
per 1,000 Btu/hr (4.8 m3 per 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 un­conned 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 Conned or Unconned Space
Use this work sheet to determine if you have
a conned or unconned space.
Space: Includes the room in which you will install
replace 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. 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 replace __________ Btu/Hr Gas water heater* __________ Btu/Hr Gas furnace __________ Btu/Hr
Vented gas heater __________ Btu/Hr Gas replace 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 replace + _________ 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 conned
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 unconned space, remove door to adjoin­ing 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 replace, if lower Btu/
Hr size makes room unconned.
If the actual Btu/Hr used is less than the maxi-
mum Btu/Hr the space can support, the space is an unconned space. You will need no additional
fresh air ventilation.
WARNING: If the area in which
the heater may be operated does not meet the required volume for indoor combustion air, combus­tion and ventilation 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 applicable local codes.

Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must provide two perma­nent openings: one within 12" of the ceiling
and one within 12" of the oor. 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.

of the following:
• operate the logs only with the
ue damper open
• raise the mantel to an accept-
able height
• remove the mantel
FLOOR CLEARANCES
A. If installing appliance on the oor level,
you must maintain the minimum distance of 14" to combustibles (see Figure 8).
B. If combustible materials are less than 14"
to the replace, you must install appliance at least 5" above the combustible ooring
(see Figure 9).
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, ap­pliance must be installed only in a solid-fuel burning replace with a working ue and con­structed of noncombustible material.
For Massachusetts Residents Only: Instal­lation of this gas log set as a vented appliance in the Commonwealth of Massachusetts re­quires the damper be permanently removed or welded in the fully open position.
If your heater is a manually-controlled model,
you may use this heater as a vented product. There are three reasons for operating your heater in the vented mode.
1. The replace does not meet the clearance
to combustibles requirements for vent­free operation.
2. State or local codes do not permit vent­free operation.
3. You prefer vented operation.
If reasons number 1 or 2 above apply to you, you must permanently open chimney ue
damper. You must install the damper clamp
accessory (to order, see Accessories, page
42). This will insure vented operation (see Fig-
ure 10). The damper clamp will keep damper open. Installation instructions are included with clamp accessory.
See chart below for minimum permanent ue
opening you must provide. Attach damper clamp so the minimum permanent ue open­ing will be maintained at all times.

INSTALLING HEATER BASE ASSEMBLY
WARNING: You must secure
this heater to replace oor. If
not, heater will move when you
adjust controls. Moving heater may cause a gas leak.
WARNING: If installing in a sunken replace, special care is needed. You must raise the replace oor to allow access to heater control panel. This will in­sure adequate air ow and guard against sooting and controls be­ing damaged. Raise replace oor with noncombustible material. Make sure material is secure.
CAUTION: Do not pick up heater base assembly by burn­ers. 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 exible gas hose and ttings (only
provided with TF burner system series) (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 Ac­cessories, page 42) before installing gas log heater. See installation instructions included with the kit.
1. Apply pipe joint sealant lightly to male
threads of the 1/2 NPT side of gas tting
elbow (provided) and connect to inlet
side of gas control. Remove gas tting from exible gas hose (provided) before
connecting to elbow (see Figure 11).
2. Position heater base assembly in re­place.
3. Mark screw locations through holes in front panel of base (see Figure 12). If
installing in a brick-bottom replace, mark
screw locations in mortar joint of bricks.
4. Remove heater base from replace.
5. Drill holes at marked locations using 3/16" drill bit.
6. Attach base, through holes in back side pan­els of base, to replace oor using masonry
screws provided in hardware package (see Figure 12).
7. Connect to gas supply. See Connecting To Gas Supply.

CONNECTING TO GAS SUPPLY
WARNING: This appliance requires a 1/2" NPT (National Pipe Thread) inlet connection to the pressure regulator.
WARNING: A qualied ser­vice person must connect heater to gas supply. Follow all local codes.
CAUTION: Never connect
propane/LP replace directly to the propane/LP supply. This heater requires an external regu­lator (not supplied). Install the external regulator between the heater and propane/LP supply.
WARNING: Never connect
natural gas replace 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 exible gas line with gas con-
nector (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
13. Pointing the vent down protects it from
freezing rain or sleet.
CAUTION: Use only new,
black iron or steel pipe. In­ternally-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. If pipe is too small, 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 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 replaces.
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 sealant that is resistant to liquid petroleum (LP) gas.
* Purchase the optional equipment shutoff
valve from your dealer.
