AIR FOR COMBUSTION AND VENTILATION
Unusually Tight Construction
Confined and Unconfined Space
WARNING: This heater shall
not be installed in a confined
space or unusually tight construc-
tion unless provisions are provided
for adequate combustion and ven-
tilation air. Read the following in-
structions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
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
defined as construction where:
a) walls and ceilings exposed to
the outside atmosphere have a
continuous water vapor retarder with
a rating of one perm ( 6×10-11 kg per
pa-sec-m2) or less with openings
gasketed or sealed and
The National Fuel Gas Code, ANS
Z223.1 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
unconfining 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 in-
stalled in that space. Rooms com-
municating directly with the space
in which the appliances are
installed*, through openings not
furnished with doors, are consid-
ered a part of the unconfined
space.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from
National Fuel Gas Code, NFPA 54/
ANSZ 223.1.Section 5.3, 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
b) weather stripping has been
added on windows that open and
doors and
c) caulking or sealants are ap-
plied 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.
This heater shall not be installed
in a confined space or unusually
tight construction unless provisions
are provided for adequate com-
bustion and ventilation air.
The information on pages 4 through
5 will help you classify your space
and provide adequate ventilation.
If your home meets all of the
three criteria above, you must pro-
vide additional fresh air. See Ven-
tilation Air From Outdoors, page 5.
If your home does not meet all of the
three criteria above, proceed to
Determining Fresh-Air Flow For
Heater Location, below.
* Adjoining rooms are communi-
cating only if there are doorless
passageways or ventilation grills
between them.
AIR FOR COMBUSTION AND VENTILATION
DETERMINING FRESH AIR FLOW FOR HEATER LOCATION
Determining if You Have a Confined or Unconfined Space
Use this worksheet to determine if you have a confined or unconfined 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 width height).
×
×
Length Width Height=
cu.ft. (volume of space)
×
×
Example: Space size 20ft. (length) 16ft. ( width) 8ft. (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. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support.
(volume of space)÷50 cu. ft.=(Maximum Btu/Hr the space can support)
Example: 2560 cu. ft. (volume of space)÷50 cu.ft.=51.2 or 51,200(maximum Btu/Hr the space can support)

*Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and
vents to the outdoors.
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)
56,000 Btu/Hr(actual amount of Btu/Hr used)
The space in the above example is a confined 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 unconfined
space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation Air From
Inside Building (below).
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors (below) .
C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined.
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an
unconfined space. You will need no additional fresh air ventilation.
WARNING: If the area in which the heater may be operated is smaller than that defined as
an unconfined space or if the building is of unusually tight construction, provide adequate
combustion and ventilation air by one of the methods described in the National Fuel Gas Code,
ANS Z223.1, Section 5.3 or applicable local codes.
Ventilation Air From lnside Building
This fresh air would come from an adjoining un-
confined space. When ventilating to an adjoining
unconfined space, you must provide two perma-
nent openings: one within 12" of the ceiling and
one within 12" of the floor 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. NFPA 24/ANS Z223.1. Section 5.3, Air
for Combustion and Ventilation for required size of
ventilation grills or ducts.
Ventilation Air From Outdoors
Figure 2 -Ventilation Air from Inside Building
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 floor. Connect these items directly to the out-
doors or spaces open to the outdoors. These spaces
include attics and crawl spaces. Follow the National
Fuel Gas Code, NFPA 54/ANS Z223.1, Section 5.3.
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.

CAUTION: This heater creates
warm air currents. These currents
move heat to wall surfaces next to
heater. Installing heater next to vinyl
or cloth wall coverings or operating
heater where impurities (such as
tobacco smoke, aromatic candles,
cleaning fluids, oil or kerosene lamps,
etc.) in the air exist,may discolor walls.

WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vaporis a by-product of gas combustion.An unvented room
heater productes approximately one (1) ounce (30ml) of wter for
every 1,000 BTU’s (.3KW’s) of gas input per hour.
The following steps will help insure that water vapor does not
become a problem.
1. Be sure the heater is sized properly for the application,
including ample combusion air and circulation air.
2. If high humidity is experienced, a dehumidifier may be used
to help lower the water vapor content of the air.
3. Do not use an unvented room heater as the primary heat
source.
Unvented room heaters are remommended as supplemental heat
(a room) rather than a primary heat source (an entire house) .In
most supplemental heat application, the water vapor does not create
a problem. In most applications, the water vapor enhances the low
humidity atmosphere experience during cold weather.

THERMOSTAT CONTROL
OPERATION
The thermostat control knob can be
set to any comfort level between HI
and LO. The thermostat will gradually
modulate the heat output and flame
height from higher to lower settings,
or pilot, in order to maintain the
comfort level you select. The ideal
comfort setting will vary by household
depending upon the amount of space
to be heated, the output of the
central heating system, etc.
Note: Selecting the HI setting with the
control knob will cause the
burners
to remain fully on, without modulating
down in most cases. The LO and HI
setting has temperature range of ap-
proximately 55 F(12.78 C) to 90 F(32.
22 C),respectively.This is the tempera-
ture at the hydraulic thermostat bulb not
the room temperature.The owner is ad-
vised to determine the particular heat
setting that is desired for comfort, as
heating requirements are different for
every owner.
Attention:If the owner does not want
the main burner to ignite and turns the
gas control knob to the LO setting, the
main burner will still ignite if the
temperature at the hydraulic thermo-
stat bulb drops to 55 F(12.78 C).
If no heat is desired,turn the gas cntrol
knob to the PILOT position.

the pilot assembly (see Figure 18).
With the unit off, lightly blow air
through the air inlet hole. You may
blow through a drinking straw if
compressed air is not available.
CLEANING AND MAINTENANCE
WARNING: Turn off heater and
let cool before cleaning.
CAUTION: You must keep control
areas, burner, and circulating air pas-
sageways of heater clean. Inspect these
areas of heater before each use. Have
heater inspected yearly by a qualified
service person. Heater may need more
frequent cleaning due to excessive lint
from carpeting, bedding material, pet
hair, etc.
CLEANING ODS/IGNITOR AND
BURNER
Clean with a vacuum cleaner.
CLEANING MAIN AIR INLET HOLE
We recommend that you clean the
unit every three months or after 2500
hours of operation. We also recom-
mend that you keep the burner tube
and pilot assembly clean and free of
dust and dirt. To clean these parts
we recommend using compressed air
no greater than 30 PSI. You can use a
vacuum cleaner in the blow position. If
using compressed air in a can, please
follow the directions on the can. If you
don't follow directions on the can, you
could damage the pilot assembly.

LOGS
1. Shut off the unit, including the
pilot. Allow the unit to cool for at least
thirty minutes.
ꢀ
If you remove logs for cleaning,
2. Inspect burner, pilot and primary air inlet
holes on injector holder for dust and dirt
(see figure 17).
3. Blow air through the ports/slots and
holes in the burner.
4. Check the injector holder located at
the end of the burner tube again.
Remove any large particles of dust, dirt,
lint, or pet hair with a soft cloth or
vacuum cleaner nozzle.
5. Blow air into the primary air holes on
the injector holder.
6. In case any large clumps of dust have
been pushed into the burner, repeat steps
3 and 4.
refer to Installing Logs, page
15, to properly replace logs.
Replace log(s) if broken or chipped
(dime-sized or larger).
ꢀ
MAIN BURNER
Periodically inspect all burner flame
holes with the heater running. All
slotted burner flame holes should
be open with yellow flame present. All
round burner flame holes should be
open with a small blue flame
present. Some burner flame holes
may become blocked by debris or
rust, with no flame present. If so,
turn off heater and let cool. Either
remove blockage or replace burner.
Blocked burner flame holes will
create soot.
