WARNING: This heater shall
not be installed in a room or
space unless the required vol-
ume of indoor combustion air
is provided by the method de-
scribed in the National Fuel Gas
Code,ANSI Z223.1/NFPA54, the
International Fuel Gas Code, or
applicablelocalcodes.Readthe
following instructions to insure
proper fresh air for this and
other fuel-burning appliances
in your home.
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 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.
Today’s homes are built more energy efficient
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.
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:
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.

side atmosphere have a continuous

2. Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
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.
________ (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.

above,youmustprovideadditionalfreshair.

The National Fuel Gas Code, ANSI Z223.1.3/
NFPA54 defines a confined 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 unconfined 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 aggregate 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.
* Do not include direct-vent gas appliances.
Direct-vent draws combustion air from the
outdoors and vents to the outdoors.

Determining if You Have a Confined or
Unconfined Space
The space in the above example is a confined
space because the actual Btu/Hr used is more
Use this work sheet to determine if you have than the maximum Btu/Hr the space can sup-
port. You must provide additional fresh air. Your
options are as follows:
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.
A. Rework worksheet, adding the space of an
adjoining room. If the extra space provides an
unconfined space, remove door to adjoining
room or add ventilation grills between rooms.
See Ventilation Air From Inside Building,
page 8.
1. Determine the volume of the space (length
x width x height).
Length x Width x Height =__________cu. ft.
(volume of space)
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors, page 8.
Example: Space size 20 ft. (length) x 16 ft.
(width) x 8 ft. (ceiling height) = 2560 cu. ft.
(volume of space)
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.
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.

WHAT TO DO IF YOU SMELL GAS
FOR YOUR SAFETY
• Do not try to light any appliance.
• Do not touch any electric switch; do
not use any phone in your building.
• Immediately call your gas supplier
from a neighbor’s phone. Follow the
gas supplier’s instructions.
READ BEFORE LIGHTING
WARNING: If you do not fol-
low these instructions exactly,
a fire or explosion may result
causing property damage, per-
sonal injury or loss of life.
• If you cannot reach your gas supplier,
call the fire department.
C. Use only your hand to push in or turn
the gas control knob. Never use tools.
If the knob will not push in or turn by
hand, don’t try to repair it, call a quali-
fied service technician or gas supplier.
Force or attempted repair may result in
a fire or explosion.
A. This appliance has a pilot which must
be lighted by hand. When lighting
the pilot, follow these instructions
exactly.
B. BEFORE LIGHTING smell all around
the appliance area for gas. Be sure to
smell next to the floor because some
gas is heavier than air and will settle
on the floor.
D. Do not use this appliance if any part
has been under water. Immediately call
a qualified service technician to inspect
the appliance and to replace any part of
the control system and any gas control
which has been under water.

THERMOSTAT
CONTROL OPERATION
OPERATING
BLOWER
The thermostatic control used on this fireplace
differs from standard thermostats. Standard
thermostats simply turn on and off the burner.
The thermostat used on this fireplace senses the
room temperature. The thermostat adjusts the
amount of gas flow to the burner. This increases
or decreases the burner flame height. At times
the room may exceed the set temperature. If so,
the burner will shut off. The burner will cycle back
on when room temperature drops below the set
temperature.
This blower has three settings: ON, OFF, and
AUTO. In the ON position, blower will operate
constantly. In the OFF position, blower will not
operate. In theAUTO position, blower will start
when thermostat senses a sufficient increase
in firebox temperature.
Note: Your fireplace and thermostat blower
will not turn on and off at the same time. The
fireplace may run for several minutes before
blower turns on. After heater modulates to
pilot position, blower will continue to run.
Blower will shut off after firebox temperature
decreases.
The control knob can be set to any heat level
between HI and LO.
Note: The thermostat sensing bulb measures
the temperature of air near the fireplace
cabinet. This may not always agree with
room temperature (depending on housing
construction, installation location, room size,
open air temperatures, etc.). Frequent use of
your fireplace will let you determine your own
comfort levels.
Note: It is safe to operate fireplace with blower
turned off. However, blower helps distribute
heated air from fireplace.

pattern often.
BURNER FLAME PATTERN
Figure 33 shows a correct burner flame pat-
