WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An
unvented room heater produces approximately one
(1) ounce (30ml) of water for every 1,000 BTU’s
(.3KW’s) of gas input per hour.
Unvented room heaters are recommended as supplemental heat (a room) rather than a primary heat
source (an entire house). In most supplemental heat
applications, the water vapor does not create a
problem. In most applications, the water vapor enhances the low humidity atmosphere experienced
during cold weather.
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 combustion 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.

FRESH AIR FOR
COMBUSTION AND
VENTILATION
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from
National Fuel Gas Code. NFPA
54/ANS Z223.1, 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
The information on pages 4
through 6 will help you classify
your space and provide adequate
ventilation.
WARNING: This heater
shall not be installed in a
confined space or unusually
tight construction unless
provisions are provided for
adequate combustion and
ventilation air. Read the
following instructions to
insure proper fresh air for this
and other fuel-burning
appliances in your home.
Confined and
Unconfined Space
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 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 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 unconfined space.
This heater shall not be installed
in a confined space or unusually
tight construction unless
provisions are provided for
adequate combustion and
ventilation air.
*
Adjoining rooms are
communicating only if there are
doorless passageways or
ventilation grills between them.
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.
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
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
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 floors, between wallceiling 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 5 and 6.
If your home does not meet all of
the three criteria above, see
Determining Fresh-Air Flow for
Heater Location, page 4, 5.
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)=2560cu. 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)

WARNING: Rework worksheet, adding the space of the adjoining
unconfined space. The combined spaces
must have enough fresh air to supply all
appliances in both spaces.
AIR FOR COMBUSTION
AND VENTILATION
Continued
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an
adjoining unconfined space. When
ventilating to an adjoining unconfined
space, you must provide two permanent
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 54/ANS Z223.1.
Section 5.3, Air for Combustion and
Ventilation for required size of
ventilation grills or ducts
Example:
Gas water heater 44,000 Btu/Hr
Vent free heater + 10,000 Btu/Hr
Total = 54,000 Btu/Hr
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.
3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free heater Btu/Hr
Gas water heater* Btu/Hr
Gas furnace Btu/Hr
Vented gas heater Btu/Hr
Gas Fireplace logs Btu/Hr
Other gas appliances* + Btu/Hr
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)
54,000 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, page 5.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 6 .
C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined.

VENTILATION AIR
Ventilation Air From Outdoors
Provide extra fresh air by using
ventilation grills or duels: 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
outdoors 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

INSTALLATION
CONNECTING TO GAS SUPPLY
WARNING: A qualified
service person must connect
heater to gas supply. Follow all
local codes.
WARNING: This appliance
requires a 3/8" NPT (National Pipe
Thread) inlet connection
to the pressure regulator.
CAUTION: Never connect
heater directly to the
propane/LP supply. This heater
requires an external regulator
(not supplied). Install the
external regulator between the
heater and propane/LP supply.
*A CSA/AGA design-certified equipment shutoff valve with 1/8" NPT tap is
an acceptable alternative to test gauge connection. Purchase the optional
CSA/AGA design-certified equipment shutoff valve from
your dealer. See Accessories, page 17.
Figure 14 -Gas Connection
The installer must supply an
external regulator. The external
regulator will reduce incoming gas
pressure. You must reduce
incoming gas pressure to between
11 and 14 inches of water. If you
do not reduce incoming gas
pressure, heater regulator damage
could occur. Install external
regulator with the vent pointing
down as shown in Figure 13.
Pointing the vent down protects it
from freezing rain or sleet.

Vent Pointing Down
excess sealant from going into
pipe. Excess sealant in pipe could
result in clogged heater valves.
IMPORTANT: Install an equipment
shutoff valve in an accessible
location. The equipment shutoff
valve is for turning on or shutting
off the gas to the appliance.
CAUTION: Use only new,
black iron or steel pipe.
Internally-tinned copper tubing
may be used in certain areas.
Check your local codes. Use pipe
of large enough diameter to
allow proper gas volume to heater.
If pipe is too small,
undue loss of pressure will occur.
Typical Inlet Pipe Diameters
All models up to 20,000 BTU’s use
3/8’’ or greater pipe;
All models 25,000 BTU’s and higher,
use 1/2” or greater pipe.
Installation must include an
equipment 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 14).
Install sediment trap in supply line
as shown in Figure 14. Locate
sediment trap where it is within
reach for cleaning. Locate
sediment 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.
IMPORTANT: Hold pressure
regulator with wrench when
connecting it to gas piping and/or
fittings.
CAUTION: Use pipe joint
sealant that is resistant to
liquid petroleum (LP) gas.

nTHERMOSTAT CONTROL OPERATIONn
The thermostatic control used on this
model differs from standard
thermostats.Standard thermostats
simply turn on and off the burner. The
thermostat used on this heater senses
the room temperature. 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. The
control knob can be set to any comfort
level between HI and LO.
Note: The thermostat sensing bulb mea-
sures the temperature of air near the
heater cabinet.This may not always agree
with room temperature(depending on
housing construction, installation location,
room size, open air temperature,etc.)
Frequent use of your heater will let you
determine your own comfort levels.

ODS/PILOT AND BURNER
l Use a vacuum cleaner, pres-
surized air, or a small, soft
bristled brush to clean.
CLEANING BURNER
PILOT AIR INLET HOLE
We recommend that you clean the
unit every 2,500 hours of operation or
every three months. We also
recommend 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 PSl.Your local
computer store, hardware store, or
home center may carry compressed
air in a can. 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.
1. Shut off the unit, including the
pilot. Allow the unit to cool for
at least thirty minutes.
2. Inspect burner and pilot for dust
and dirt.
3. Blow air through the ports/slots
and holes in the burner.
Also clean the pilot assembly. A
yellow tip on the pilot flame indicates dust and dirt in the pilot
assembly. There is a small pilot air
inlet hole about two inches from
where the pilot flame comes out of
the pilot assembly (see Figure 25).
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.
Figure 25 - Pilot Inlet Air Hole
CABINET
Air Passageways
l Use a vacuum cleaner or
pressurized air to clean.
Exterior
l Use a soft cloth dampened with
a mild soap and water mixture.
Wipe the cabinet to remove dust.
nINSPECTING BURNERn
Check pilot flame pattern and
burner flame pattern often.
PILOT FLAME PATTERN
Figure 21 shows a correct pilot
flame pattern. Figure 22 shows an
incorrect pilot flame pattern. The
incorrect pilot flame is not touching
thermocouple. This will cause the
thermocouple to cool. When the
thermocouple cools, the heater will
shut down. If pilot flame pattern is
incorrect, as shown in Figure 22.
l turn heater off (see To Turn Off
Gas to Appliance on page 11
for non-thermostat models or
