REMOTE CONTROL ACCESSORIES
PRODUCT FEATURES
There are four optional remote controls
that can be purchased separately for this
replace insert:
• wall switch
• wall thermostat
OPERATION
This vent-free replace insert 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
embers. When used without the blower, the
replace insert requires no electricity making
it ideal for emergency backup heat.
SAFETY DEVICE
This replace insert 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 system
shuts off the replace insert if there is not
enough fresh air.
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 efcient
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. During heating months, home owners want their
homes as airtight as possible.
While it is good to make your home energy
efcient, 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 classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned 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 dened as
construction where:
PIEzO IGNITION SYSTEM
This replace insert has a piezo ignitor. This
system requires no matches, batteries or
other sources to light replace insert.
BLOWER ASSEMBLY
This replace insert is equipped with a blower
assembly. The blower operates thermostatically and has a variable control. The blower
circulates heated air from the replace insert
into the room. Use of blower is optional.
• hand-held ON/OFF remote
• hand-held thermostat remote

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
Fresh-Air Flow for Heater Location.
Conned and Unconned Space
The National Fuel Gas Code ANSI Z223.1/
NFPA 54 denes a conned space as a space
whose volume is less than 50 cubic feet per
1,000 Btu per hour (4.8 m3 per kw) of the ag-
gregate input rating of all appliances installed in
that space and an unconned space as a space
whose volume is not less than 50 cubic feet per
1,000 Btu per hour (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 unconned 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 Conned or
Unconned Space
Use this work sheet to determine if you have
a conned or unconned 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)
AIR FOR COMBUSTION AND VENTILATION
Continued
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. 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: 3168 cu. ft. (volume of space) x 20
= 63,360 (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
Tota = _________ 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 of Btu/Hr
used)
Example: 63,360 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 conned
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 pro-
vides an unconned 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 unconned.

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. Any outside
air ducts and/or ash dumps in the replace shall
be permanently closed at the time of appliance
installation.

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 Internation-
al Fuel Gas Code, or applicable
local codes.
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining
unconned space. When ventilating to an
adjoining unconned 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 3). You can also remove door
into adjoining room (see option 3, Figure 3).
