WARNING: This heater shall
not be installed in a room or space
unless the required volume of in-
door 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 lo-
cal codes. Read the following in-
structions 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 insula-
tion, 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. During 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
PRODUCT FEATURES
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 realistic,
dancing yellow ames. 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 product
(ANSI Z21.60) by opening ue damper (non-
thermostat operation only).
APPLICATION
These multisided logs are designed to be
equally beautiful when viewed from any angle.
They are designed specically for use in see-
through, peninsula, and island reboxes with
multiple openings. You may also install this
log heater in a standard rebox.
SAFETY PILOT
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.
PIEZO IGNITION SYSTEM
This heater has a piezo ignitor. This system
requires no matches, batteries, or other
sources to light heater.
REMOTE CONTROL ACCESSORIES
There are four optional remote controls that
can be purchased separately for this log
heater:
• wall switch
• wall thermostat
• hand-held ON/OFF remote
• hand-held thermostat remote
See Accessories, page 30.
Note: The wall thermostat or hand-held
thermostat may not be used where vented
decorative listing is required.
AIR FOR COMBUSTION AND VENTILATION
air must enter your home. All fuel-burning ap-
pliances 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, SAir 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

www.fmiproducts.com
110398-01F 7
and ventilation. However, in buildings of un-
usually 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 (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 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 Fresh-
Air Flow For Heater Location.
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 un-
con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 heater 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 sup-
port.
________ (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 heater _________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 heater + _________ 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 of Btu/Hr
used)
Example: 51,200 Btu/Hr (maximum the
space can support)
73,000 Btu/Hr (actual amount of
Btu/Hr used)

Continued
The space in this 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 adjoin-
ing room or add ventilation grills between
rooms. See Ventilation Air From Inside
Building.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors.
C. Install a lower Btu/Hr heater, 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, combus-
tion and ventilation air shall be
provided by one of the methods
described in the National Fuel
Gas Code,ANSI Z223.1/NFPA54,
the International Fuel Gas Code,
or applicable local codes.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining
unconned space. When ventilating to an
adjoining unconned space, you must provide
two permanent openings: one within 12" of the
ceiling and one within 12" of the oor on the
wall connecting the two spaces (see options
1 and 2, Figure 2). You can also remove door
into adjoining room (see option 3, Figure 2).
Follow the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Air for Combustion and
Ventilation for required size of ventilation
grills or ducts.

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 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 thermo-
stat-controlled power vent. Heated air entering
the attic will activate the power vent.

MANTEL CLEARANCES
In addition to meeting noncombustible mate-
rial clearances, you must also meet required
clearances between replace openings and
mantel shelf on each side of the replace. If
you do not meet the clearances listed below,
you will need a hood.
Determining Minimum Mantel Clearance
If you meet minimum clearance between
mantel shelf and top of replace opening, a
hood is not required (see Figure 6).
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 clear-
ances required. Follow minimum clearances
shown in Figure 7 when using hood.
NOTICE: Surface temperatures
of adjacent walls and mantels
become hot during operation.
Walls and mantels above the
firebox may become hot to
the touch. If installed properly,
these temperatures meet the
requirement of the national
product standard. Follow all
minimum clearances shown in
this manual.

ACCESSORY FOR VENTED
OPERATION
Note: When used as a vented heater, ap-
pliance must be installed only in a solid-fuel
burning replace with a working ue and con-
structed of noncombustible material.
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 vent-
free operation
2. State or local codes do not permit vent-
free 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
30). 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 open-
ing will be maintained at all times.

CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-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. Lo-
cate NPT tap within reach for test gauge hook
up. NPT tap must be upstream from heater
(see Figure 14, page 15).
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.
We recommend that you install sediment trap
in supply line as shown in Figure 14, page
15. Locate sediment trap where it is within
reach for cleaning. Install in piping system
between fuel supply and heater. Locate sedi-
ment trap where trapped matter is not likely

CONNECTING TO GAS SUPPLY
WARNING: A qualified
service person must connect
heater to gas supply. Follow all
local codes.
WARNING: Never connect
propane/LP heater directly to the
propane/LP supply. This heater
requires an external regulator
(not supplied). Install the exter-
nal regulator between the heater
and propane/LP supply.
WARNING: Never connect
natural gas heater 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 (for propane/LP units
only, 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
* A 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.
