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

ames and glowing ceramic logs/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.

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.

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

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.

www.fmiproducts.com

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.

REMOTE IGNITION AND CONTROL

This gas log set has a battery powered
electronic remote ignition and control. This
system requires no matches or other source
to light log set.

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 combus-

tion 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
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,

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 per hour (4.8 m3 per kw) of the ag-

gregate 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 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 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 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) = 2,560 cu. ft.

(volume of space)

If additional ventilation to adjoining room is sup-

plied 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: 2,560 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

Vent-free replace _________ Btu/Hr
Gas water heater* _________ Btu/Hr
Gas furnace _________ Btu/Hr

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 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 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.

MANTEL CLEARANCES

In addition to meeting noncombustible mate-

rial clearances, you must also meet required
clearances between replace opening and

mantel shelf. 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).

Figure 6 - Minimum Mantel Clearances

Without Using Hood

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.

NOTICE: Surface temperatures
of adjacent walls and mantels be­come hot during operation. Walls
and mantels above the rebox
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.

NOTICE: If your installation does
not meet the minimum clear­ances shown, you must do one

of the following:

• operate the logs only with the
ue damper open

• raise the mantel to an accept­able 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).
