OWNER’S MANUAL
PROVIDING ADEQUATE
VENTILATION
Confined and Unconfined Space
AIR FOR
The National Fuel Gas Code (ANS Z223.1,
1992 Section 5.3) 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 aggregate 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
inputratingofallappliancesinstalledinthat
space. Rooms communicating directly with
the space in which the appliances are in-
stalled*, through openings not furnished
with doors, are considered a part of the
unconfined space.
COMBUSTION AND
VENTILATION
The following are excerpts from National
Fuel Gas Code. NFPA 54/ANS Z223.1, Sec-
tion5.3, AirforCombustionandVentilation.
WARNING: This heater shall
notbeinstalledinaconfinedspace
or unusually tight construction
unless provisions are provided
foradequatecombustionandven-
tilation air. Read the following in-
structions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
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 5 through 7 will
help you classify your space and provide
adequate ventilation.
Today’s homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
helpreduceheatlossinhomes.Homeowners
weather strip and caulk around windows and
doorstokeepthecoldairoutandthewarmair
in. During heating months, home owners
want their homes as airtight as possible.
Unusually Tight Construction
This heater shall not be installed in a con-
fined space or unusually tight construction
unless provisions are provided for adequate
combustion and ventilation air.
The air that leaks around doors and win-
dows may provide enough fresh air for
combustion and ventilation. However, in
buildings of unusually tight construction,
you must provide additional fresh air.
* Adjoining rooms are communicating only
iftherearedoorlesspassagewaysorventila-
tion grills between them.
Unusually tight construction is de-
fined 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
appliances need fresh air for proper com-
bustion and ventilation.
a. walls and ceilings exposed to the
outside atmosphere have a con-
tinuous water vapor retarder with
a rating of one perm (6x10-11 kg
per pa-sec-m2) or less with open-
ings gasketed or sealed and
Exhaustfans, fireplaces, clothesdryers, and
fuel burning appliances draw air from the
house to operate. You must provide ad-
equate fresh air for these appliances. This
will insure proper venting of vented fuel-
burning appliances.
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, be-
tween sole plates and floors, be-
tween wall-ceiling joints, be-
tween wall panels, at penetra-
tions 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 7.

criteriaabove,proceedtoDeterminingFresh-

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:Includestheroominwhichyouwillinstallheaterplusanyadjoiningroomswithdoorlesspassagewaysorventilationgrillsbetween
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. 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)
3. Add the Btu/Hr of all fuel burning appliances in the space.

Total = ___________________Btu/Hr
* 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)
60,000 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 cansupport.
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 adjoin-
ing room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 7.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 7.
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 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, 1992, Section 5.3 or applicable local codes.

in Figure 21. Locate sediment trap where it
is within reach for cleaning. Locate sedi-
ment trap where trapped matter is not likely
to freeze. A sediment trap traps moisture
and contaminants. This keeps them from
going into heater controls. If sediment trap
is not installed or is installed wrong, heater
may not run properly.
Installation must include a manual shutoff
valve, union, and plugged 1/8" NPT tap.
Locate NPT tap within reach for test gauge
hook up. NPT tap must be upstream from
heater (see Figure 21). An appliance main
gas valve (manual shutoff valve) must be
located within easy reach for turning the gas
supply on and off.
CAUTION: A qualified service
person must connect heater to
gassupply.Followalllocalcodes.
Never connect heater directly to
the propane/LP supply. This
heater requires an external regu-
lator (not supplied). Install the
external regulator between the
heater and propane/LP supply.
IMPORTANT: Hold pressure regulator
with wrench when connecting it to gas pip-
ing and/or fittings.
The installer must supply an external regu-
lator. The external regulator will reduce
incoming gas pressure. You must reduce
incominggaspressuretobetween11and14
inches of water. If you do not reduce incom-
ing gas pressure, heater regulator damage
could occur. Install external regulator with
the vent pointing down as shown in Figure
20. Pointing the vent down protects it from
freezing rain or sleet.

ing the thermocouple. This will cause the
thermocouple to cool. When the thermo-
couple cools, the heater will shut down.
Note: When using the heater the first time,
the flame will be yellow for approximately
one hour until the log cures.
The thermostatic control used on this
heater differs from standard thermostats.
Standard thermostats simply turn on and
off the burner. The thermostat used on
this heater senses the room temperature.
The thermostat adjusts the amount of gas
flow to the burner. This increases or de-
creases the burner flame height. At times
the room may exceed the set temperature.
If so, the burner will shut off. The burner
willcyclebackonwhenroomtemperature
drops below the set temperature.
WARNING: If yellow tipping
occurs, your heater could pro-
duce increased levels of carbon
monoxide. If burner flame pat-
tern shows yellow tipping, follow
instructions,bottomofthispage.
If pilot flame pattern is incorrect, as shown
in Figure 27
• turn heater off (see To Turn Off Gas to
Appliance, page 14)
• see Troubleshooting, pages 16 through 18

This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that fail or become damaged
