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-burning appliances in your home.
Providing Adequate Ventilation
The following are excerpts from National Fuel Gas Code, NFPA 54/ANSI 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 5 through 6 will help you classify your space and provide adequate ventilation.
Confined and Unconfined Space
The National Fuel Gas Code, ANSI 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 connecting 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 connecting only if there are doorless passageways or ventilation grills between them.
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 (6×10-11kg 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 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”. If your home does not meet all of the three criteria above, proceed to “Determining Fresh-Air Flow
For Heater Location”.
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=
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)
3. Add the Btu/Hr of all fuel burning appliances in the space.

*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”.
b) Vent room directly to the outdoors. See “Ventilation Air From Outdoors”.
c) Install a lower Btu/Hr heater if lower Btu/Hr size makes room unconfined.
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, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation, or
applicable local codes.
Ventilation Air From lnside 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 inches of the ceiling and one within 12 inches
of the floor on the wall connecting the two spaces (see options 1 and 2,
Figure 2). You can also remove the door into adjoining room (see option
3, Figure 2). Follow the National Fuel Gas Code. NFPA 54/ANSI Z223.1,
Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts.
Figure 1 - Ventilation Air from Outdoors
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must provide
two 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. These spaces include attics and crawl spaces. Follow the National Fuel Gas Code, NFPA 54/ANSI 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. 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.

Remove heater from carton.
Remove all protective packaging applied to heater for shipping
Check heater for any shipping damage. If heater is damaged, promptly inform dealer where you bought
heater.
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 (.3 KWs)
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 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.
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 experience during cold weather.
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 heating system, you may
run system’s circulating blower while using heater. This will help circulate the heat throughout the house. In
the event of a power outage, you can use this heater as your primary heat source.
Caution: If you install the heater in a home garage:
• Heater pilot and burner must be at least 18 inches above the floor.
• Place heater where moving vehicle will not hit it.
WARNING: A qualified service person must install heater. Follow all local codes.
WARNING: Never install the heater
• in a bedroom or bathroom
• in a recreational vehicle
• where curtains, furniture, clothing, or other flammable objects
are less than 36 inches from the front, top, or sides of the heater
• in high traffic areas
• in windy or drafty areas
WARNING: Maintain the minimum clearances shown in Figure
4. If you can, provide greater clearances from floor, ceiling, and
joining wall.
CAUTION: This heater creates warm air currents. These current
move heat to wall surfaces next to heater. Installing heater next to
vinyl or cloth wall coverings or operating heater where impurities
oil or kerosene lamps, etc.) in the air exist may discolor walls.

INSTALLATION
CONNECTING TO GAS SUPPLY
WARNING: A qualified service technician must connect heater to gas supply. Follow all local codes.
WARNING: This appliance requires a 3/8-inch NPT (National Pipe Thread) inlet connection to the pressure
regulator.
WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas.
WARNING: Do not over tighten gas connections.
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 1/2-in. diameter or greater to allow proper gas volume to heater.
If pipe is too small, undue loss of pressure will occur.
NATURAL GAS MODELS:
CAUTION: Check your gas line pressure before connecting heater to gas line. Gas line pressure must be
no greater than 10.5 inches of water. If gas line pressure is higher, heater regulator damage could occur.
pROPANE MODELS:
CAUTION: Never connect heater directly to the gas supply. This heater requires an external regulator (not
supplied). Install the external regulator between the heater and gas supply.
CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting into gas piping
and/or fittings.
CAUTION: Use pipe joint sealant that is resistant to gas (Propane or Natural Gas).
11
Typical Inlet Pipe Diameters
Use 3/8-inch black iron pipe or greater.
Installation must include an 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 12).
IMPORTANT: Install an equipmen
shutoff valve in an 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 into pipe. Excess sealant in pipe
could result in clogged heater valves.
Figure 12 - Gas Connection (inches) for NG
*A CSA/AGA design-certified equipment shutoff valve with 1/8-inch NPT tap
is an acceptable alternative to test gauge connection. Purchase the optional
CSA/AGA design-certified equipment shutoff valve from your dealer.
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.
Install sediment trap in supply line as shown in Figure 12.
Place sediment trap where it is within reach for cleaning. Place
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.

THERMOSTAT CONTROL OPERATION (only for ML/N100TBH )
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 1 and 5.
MN/L100TBH
Note: The thermostat sensing bulb measures 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.
TO TURN OFF GAS TO APPLIANCE

INSPECTING BURNER
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 19 shows a correct pilot flame pattern. Figure 20 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching
the 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 20.
• turn heater off (see “To Turn Off Gas to Appliance” on page 15)
• see Troubleshooting pages 18 through 20.
WARNING: If yellow tipping occurs, your heater could produce
increased levels of carbon monoxide. If burner flame pattern shows yellow
tipping, follow instructions at bottom of this page.
Figure 19 - Correct Pilot Flame Pattern
Figure 20 - Incorrect Pilot Flame Pattern
Notice: Do not mistake orange flames with yellow tipping. Dirt or other fine
particles enter the heater and burn causing brief patches of orange flame.
BURNER FLAME PATTERN
Figure 21 shows a correct burner flame pattern. Figure 22 shows an
incorrect burner flame pattern. If burner flame pattern is incorrect, as
shown in Figure 22.
• Turn heater off (see “To Turn Off Gas to Appliance”).
• See Troubleshooting, pages 18 through 20.

CARE 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.

Flame Pattern
ODS/PILOT AND BURNER
• Use a vacuum cleaner, pressurized 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 23). 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.
