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 BTUs (.3kWs) of gas input per hour. An unvented room heater is recommended as a
supplemental heater (a room) rather than aprimary 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 the proper size for the application, including adequate combustion air and circulation air.
2. If high humidity is experienced, the 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.
AIR FOR COMBUSTION AND 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-burningappliances in your home.
PRODUCING ADEQUATEVENTILATION
The following are excerpts from National Fuel Gas Code, NFPA54/ANSI Z 223.1,Section 5.3, Air forCombustion 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 youclassify your space and provide adequate ventilation.
Confined andUnconfined Space
The National Fuel Gas Code, ANS Z223.1 definesa confined space as a space whose volume is less than 50 cubic feet
per 1,000 Btu per hour (4.8 m^3 per kw) of the aggregate 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 m^3 per kw) of the
aggregate input rating of all appliances installed inthat space. Rooms communicating directlywith 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 ina confined space or unusually tight construction unless provisions are provided for
adequate combustionand ventilation air.
·Adjoining rooms are connecting only if there are doorless passageways or ventilation grills between them
Unusually Tight Construction
The air that leaks around doors and windows may provideenough fresh air for combustion andventilation. However, in
buildings of unusually tight construction, you must provide additional fresh air.

6
Unusually tight construction is defined as construction where:
a) walls and ceilings exposed to theoutside atmosphere have a continuous water vapor retarder with a rating of one perm
(6x10
-11
kg per pa-sec-m
2
) or less with openings gasketed or sealed and
b) weather stripping has been added on windows that can be opened 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 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 7). If your home does not meet all of the three criteria above, proceed to “Determining Fresh-Air Flow For
Heater Location: (next page).
DETERMINING FRESH-AIR FLOW FOR HEATERLOCATION
Determiningif You Have aConfined 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 volumeof the space 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 oropenings, add the volume of these rooms to the
total volumeof 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)?0 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.
Vent-free heater ______________Btu/Hr
Gas water heater* ______________Btu/Hr
Gas furnace ______________Btu/Hr
Vented gas heater ______________Btu/Hr
Gas heater 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)
56,000 Btu/Hr(actual amount of Btu/Hr used)
The space in the above example isa 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) Reworkworksheet, adding the space of an adjoining room. If the extra space provides an unconfined space,
removedoor to adjoining room or add ventilation grills between rooms. See “Ventilation Air From Outdoors,
page 7.
b) Vent room directly to the outdoors. See “Ventilation Air From Outdoors , 7.
c) Install a lowerBtu/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 unconfinedspace. You will need no
additional fresh air ventilation.
NOTE: If the area in whichthe heater may be operated is smaller than that defined asan unconfinedspace or if the
building is of unusually tight construction, provide adequate combustionand ventilation air by one of the methods
described in the National Fuel Gas Code, ANS Z223.1, Section 5.3 or applicablelocal codes.
Example:
Gas water heater 30,000 Btu/Hr
Vent-free heater +26,000 Btu/Hr
Total =56,000 Btu/Hr

7
Ventilation Air From Inside Building
This fresh air would come from adjoining unconfined space. When ventilating
to an adjoining unconfined space, you must provide two permanent openings:
one within 12 inches of the wall connecting the two spaces (see options 1 and
2, Figure 1). You can also remove door into adjoining room (see option 3,
Figure 1). 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.
Ventilation Air From Outdoors
Provideextra fresh air by using ventilation grills or duct. You must providetwo
permanent openings: one within 12 inches of the ceiling and one within 12
inches of the floor. Connect these items directly to the outdoors or spaces
open to the outdoors (see Figure 2). 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 requiredsize 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. 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.
INSTALLATION
NOTICE: This heater is intended for use as supplemental heat.
Use this heater along with your primary heating system. Do not
install this heater as your primary heat source. If you have a central
heatingsystem, you may run system’s circulating blower while using
heater. This will help circulate the heat throughout the house.
WARNING: A qualifiedtechnician must install heater. Follow all local codes.
WARNING: Never install the heater
·in a bedroom or bathroom
·in a recreational vehicle
·flammable objects are less than 42 inches from the front, top, or sides of the heater
·in high traffic areas

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 coveringsor operating heater where impurities(such as tobacco smoke,
aromatic candles, cleaning fluids, oil or kerosene lamps, etc.) in the air exist, may discolor walls.
WARNING: Maintain the minimum clearances. If you can, provide greater clearances from floor, ceiling and
adjoining sideand back walls.
IMPORTANT: Vent-free heaters add moisture to the air. Although this is beneficial,installing heater in rooms without
enoughventilation air may cause mildew to form from too much moisture. See Air for Combustion and Ventilation, pages
5 through 7.
CHECK GAS TYPE
Use only the type of gas indicated on the plate. If your gas supply can not meet that requirement, do not install heater.
Call thedealer where you purchasedheater for the proper type of heater.

CONNECTING TO GAS SUPPLY
WARNING: A qualifiedtechnician must connect heater
WARNING: This appliance requires a 3/8 NPT inlet connection
to pressure regulator (see figure 4).
CAUTION: Never connect heater directly to the gas supply. This
heater requires an external regulator (not supplied). The external
regulator between the gas supply and heater must be installed.
INSTALLATION ITEMS NEEDED
Before installing heater, make sure you have the items listed below.
·piping (check local codes)
·sealant(resistant to propane/LP gas)
·equipment shutoff valve*
·test gauge connection**
·sediment trap
·tee joint
·pipe wrench
·Flexible Gas hose (check local code)
* A CSA design-certified equipment shutoff valve with 1/8 NPT tap is an
acceptable alternative to test gauge connection. Purchase the optional
CSA design-certified equipment shutoff valve from your dealer.
WARNING: Never connect heater to private (non-utility) gas
wells. This gas is commonly known as wellhead gas. Theinstaller
must supply an external regulator. The external regulator will reduce
incoming gas pressure. You must reduce incominggas pressure to
between 11 and 14 inches of water columnfor propane and between
5 and 10.5 inches of water column for natural gas. If you do not
reduce incoming gas pressure, heater regulator damage could occur.

INSTALLATION
Continued
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 ½inch diameter or greater to
allow proper volume gas to heater. If pipe is too small, loss of
pressure will occur. Installation must includean equipment shutoff
valve, union, and plugged 1/8-inch NPT tap. Locate NPT tap
within reach for test gauge hook up. NPT tap must be upstream
from heater (see Figure 6).
*Purchase the optional CSA design-certified equipment shut off valve
from your dealer. See Accessories
**Minimum inlet pressure for purpose of input adjustment.
IMPORTANT: Install equipment shutoff valve inan accessible location. The equipment shutoff valve is for turning on
or shutting off the gas to the appliance. Apply pipe joint sealant lightly to male threads. This will prevent excess sealant
from going intopipe. Excess sealant in pipe could result in clogged heater valves.
CAUTION: Use pipe joint sealant that is resistant to gas (PROPANE or NG). We recommendthat you install a
sediment trap in a supply line as shown in Figure 6. Locate sediment trap where it is within reach for cleaning. Install in
the piping system between fuel supply andheater. Locate sediment trap where trapped matter is not likelyto 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 incorrectly, heater may not run properly.
CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting into gas piping and/or
fittings. NG Models: 5 to 10.5 W.C. Gas supplier provide external regulator for natural gas
CAUTION: Two gaslineinstallation atthe same time is forbidden. Youare not allowed toopenthe cover while
the machine is running.
Heater is pre-set at factory for propane gas, no changes are required for connecting to propane. Only a qualified installer
or service technician can perform gas selection andconnecting to gas supply.

THERMOSTATIC CONTROL OPERATION
The thermostatic control usedon this model differs from standard thermostats. Standard thermostats simply turn the
burner on and off. The thermostat used on this heater senses the room temperature. At times the room may exceedthe
set temperature. If so, the burner will shut off. The burner will cycleback on whenroom temperature drops below the set
temperature. The control knob can be set to any comfort level.

CLEANING AND MAINTENANCE
WARNING: Turn off heater and let cool before servicing.
CAUTION: You must keep control areas, burner, and circulating air passageways of heater clean. Inspect these areas of
heater before each use. Have heater inspected yearly by a qualified service technician. Heater may need more frequent
cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.
ODS/PILOT AND BURNER
Use a vacuum cleaneror pressurizedair.
CLEANING BURNER PILOT AIRINLET HOLE
We recommend that you clean the unit every 2,500 hours of operation or every three months. We also recommendthat
you keep the burner tube and pilot assembly clean and free of dust and dirt. Toclean these parts we recommend using
compressed air no greater than 30 PSI. 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 though 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 inlethole about two inches from where the pilotflame comes
out of the pilotassembly (see Figure 23). With the unit off, lightly
blow air through the air inlethole. You may blow through a
drinking straw if compressed air is not available.
