GENERAL SAFETY INSTRUCTIONS:
SAFETY : Accidents are always tragic especially because so many of them could
have been prevented with a little care and judgment. There are some basic good
practices we hope you will follow for safe use of your gas-fired room heater.
IMPORTANT : Read this user's manual carefully and completely before
trying to assemble, operate, or service this heater. Improper use of this heater
can cause serious injury or death from burns, fire, explosion, electrical shock,
and carbon monoxide poisoning.
Early signs of carbon monoxide poisoning resemble the flu, with headaches,
dizziness, or nausea. If you have these signs, the heater may not be working
properly. Get fresh air at once! Have heater serviced. Some people are more
affected by carbon monoxide than others. These include pregnant women, people
with heart or lung disease or anemia, those under the influence of alcohol, and those
at high altitudes.
Begin by insuring proper installation and servicing. Follow the installation
instructions provided with this product. Have your heater installed by a qualified
technician. Have the installer show you where the gas supply shut off valve is
located so that you know where to shut off the gas to the heater. If you smell gas,
your installer has not done a proper job of checking leaks. If the connections are not
perfectly seated or tightened, you may have a leak and therefore a faint gas smell.
Finding a leak is not a DO-IT-YOURSELF procedure. Some leaks can only be
found with the main burner gas on and this must be done by a qualified technician.
PRECAUTIONS:
✑ Never use natural gas in a unit designed for liquefied petroleum gases.
✑ Never use liquefied petroleum gases in a unit designed for natural gas.
✑ Check all joints and connections. To avoid the danger of fire, accident or
explosion, never check a potential gas leak with an open flame.
✑ This heater shall not be installed in a bedroom or bathroom.
✑ Never install the heater in any of the following locations:
ꢁ Recreational vehicle
ꢁ Where curtains, furniture, clothing, or other flammable objects are less than
36 inches from the front, top, or sides of the heater
ꢁ Fireplace
ꢁ High traffic area
ꢁ Drafty areas
✑ This heater needs fresh, outside air for ventilation to run properly. This heater
has an oxygen depletion sensor(ODS)pilot light safety system. The ODS shuts
down the heater if not enough fresh air/oxygen content(18%)is available.
✑ Never run heater in confined space. Open a door to an adjoining room to help
ventilate(For air openings, see National Fuel Code).
Page 3
✑ If heater shuts off, do not relight until you provide fresh, outside air. If heater
keeps shutting off, have it serviced.
✑ Do not run heater where :
ꢁ Flammable liquids or vapors are used or stored.
ꢁ Dusty condition exists.
✑ Never place any objects on the heater.
✑ Supervise children when they are in the same room with heater, never
allow them to sit, stand or play on or around the heater.
✑ Make sure grille guard is in place before running heater.
✑ Do not use heater if any part has been under water. Immediately call a qualified
service technician to inspect the room heater and to replace any part of the
control system and any gas control which has been under water.
✑ Keep appliance area clear and free from combustible materials, gasoline and
other flammable vapors and liquids.

PRODUCT FEATURES:
Safety Device
This heater has a pilot with an Oxygen Depletion Sensor Shutoff System
(ODS).
The ODS pilot is a required feature for vent-free room heaters. The
ODS pilot shuts off the heater if the normal air oxygen content is reduced
to 18%.
Piezo Ignition System
This heater has a piezo ignitor. This system requires no matches,
batteries, or other sources to light heater.
Thermostatic Heat Control
Thermostat has a sensing bulb, and a control valve. This results in the
greatest heater comfort. This can also result in lower gas bills.
FRESH AIR FOR COMBUSTION AND VENTILATION:
WARNING : This heater must have fresh air for proper operation. If not, poor
fuel combustion could result. Read the following instructions to insure proper fresh
air for this and other fuel-burning appliances in your home.
ADEQUATE COMBUSTION/VENTILATION AIR
All spaces in homes fall into one of the three following ventilation classifications:
ꢀ
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:
-Walls and ceilings exposed to the outside atmosphere have a continuous
water vapor retarder with a rating or one perm or less with openings gasketed or
sealed and
-Weather stripping has been added on openable windows and doors
-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.

heater should be inspected before use and at least annually by a professional
service person. More frequent cleaning may be required due to excessive lint from
carpeting and other materials. It is imperative that the control compartments,
burners and circulating air passageways of the heater be kept clean.
CONNECTING TO GAS SUPPLY :
WARNING : Never connect an unregulated gas line to the heater.
An installer supplied, design certified gas pressure regulator must be installed to
bring the gas supply pressure down to 14 inches of water column.
IMPORTANT : Check gas line pressure before connecting heater to gas line.
Gas line pressure must not be higher than 14 inches of water. If gas line pressure is
higher, heater gas pressure regulator damage could occur.
CAUTION : Use only new, black iron or steel pipe and 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
pressure loss will occur.
Typical Gas Supply Pipe Diameters

LEAK CHECKING:
GENERAL : Although all gas connections on the heater are leak tested at the
factory prior to shipment, a complete gas tightness check must be performed at the
installation site due to possible mishandling in shipment, or excessive pressure
unknowingly being applied to the appliance. Periodically check the whole system for
leaks, or immediately check if the smell of gas is detected.
BEFORE TESTING
Do not smoke while leak testing. Extinguish all open flames.
Make a soap solution of one part liquid detergent and one part water. You will need
a spray bottle, brush or a piece of rag to apply the solution to the fittings.
For LP units, check with a full cylinder.
CAUTION : NEVER LEAK TEST WITH AN OPEN FLAME
PRESSURE TESTING-GAS SUPPLY PIPING SYSTEM
ꢀThe appliance and its individual shutoff valve must be disconnected from the gas
supply piping system during any pressure testing of that system at test pressures
in excess of 1/2 psig.
ꢀ The appliance must be isolated from the gas supply piping system by closing its
individual manual shutoff valve during any pressure testing of the gas supply
piping system at test pressures equal to less than 1/2 psig.

Shutting Off Heater
ꢀTurn control knob clockwise
to the OFF position.
Shutting Off Burner Only (Pilot stays lit)
ꢀTurn control knob clockwise
to the PILOT position.
THERMOSTAT CONTROL OPERATION
The thermostat used on these models differs from standard thermostats. Standard
thermostats simply turn the burner on and off. The thermostat used on this heater
senses the room temperature. The thermostat adjusts the amount of gas flow to the
burner. This increases or decreases the burner flame height/input rating. 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.
Page 15
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 etc.). Frequent use of
your heater will let you determine your own comfort levels.
MANUAL LIGHTING INSTRUCTIONS
1. Remove lower front panel.
2. Follow steps 1 through 4 as stated under Lighting Instructions.
3. Press and turn control knob counterclockwise
to the PILOT position.
4. With control knob pressed in, strike match, hold match to pilot until pilot lights.
5. Keep control knob pressed in for 30 seconds after lighting pilot. After 30
seconds, release control knob.
6. Replace lower front panel.
INSPECTING MAIN BURNER AND PILOT BURNER
Pilot Flame Pattern
The following figures show a correct and incorrect flame patterns. The incorrect
flame is not touching the thermocouple. This will cause a nuisance shut down.
Thermocouple
Thermocouple
Pilot Burner
Pilot Burner
CORRECT
INCORRECT
If pilot flame pattern is incorrect as shown above, turn heater off and refer to
troubleshooting guide.
Burner Flame Pattern
This heater allows the view of flames and provides the simulation of a solid fuel
fireplace. The incorrect log position can cause flame impingement, which can
cause soot formation. Propane installations seem to have more of a sooting
problem due to the richness of LP gas.
Page 16
WARNING :
If heavy sooting occurs, your heater could produce increased levels of carbon
monoxide.
If gas log shows carbon deposit, turn heater off and refer to troubleshooting guide.
CARE AND MAINTENANCE :
Dust, list or debris may affect heater performance. The heater draws air into it during normal
operation. In the process dust, lint or debris will be drawn into the heater and spider webs can
build up during off season. Keep burner, gas control and combustion and circulating air
passageways clean. Inspect or have these areas inspected annually at the beginning of the
heating season by a qualified service person. Room heater may require frequent cleaning due
to excessive lint or debris depending upon the surroundings.
BEFORE CLEANING - Ensure the gas supply is off and the gas control knob
is in the off position. Make sure the heater is cool.
WARNING:DANGER OF BODILY INJURY
If fan assembly accessory is used, turn off power supply at disconnect
switch or service panel before removing any access panels from heater.
BURNER AND ODS PILOT CLEANING - Clean the exterior with soft bristle
brush, vacuum cleaner pressurized air. Never use a wooden toothpick as it may
break off and clog the ODS pilot or main burner port.
Use a flashlight to inspect the main burner inlet to ensure it is not blocked. If
obstruction can be seen, use a metal wire coat hanger that has been straightened
out.
In order to clean ODS pilot orifice, use pressurized air to blow dust out.
Sometimes blowing air backwards through the pilot will get rid of the
accumulated dirt. If that does not work, blow out any dust through primary air
openings of pilot assemblies(Daemyeong has two openings; one beneath the
bimetal strip and the second one opposite from bimetal strip. Use the one wide
open, do not try to lift the bimetal.).
AIR PASSAGEWAYS AND UNIT CASINGS - Use a vacuum cleaner or
pressurized air to clean the combustion and circulating air passageways and
dampened cloth to clean the cabinet/casing.

SOLVING COMMON PROBLEMS
The 3 most common problems associated with any gas heater are gas leaks, wrong gas
pressure and dirt.
Do Not Use Your Heater Without Checking For Leaks! Leaks can occur during shipment and
installation. A simple solution of soap and water dabbed on the fittings will bubble if a gas leak is
present. Do not take short cuts!
Wrong Gas Pressure! Too much gas pressure may severely damage your heater. Too little gas
pressure and your heater will not burn correctly. If your installer can not check gas pressure, find
one who can or call your gas supplier. Do not take shortcuts!
Dust & Dirt! This heater does require some cleaning. If the pilot light will not stay lit or if one brick is
not as bright as another, your heater is probably due for a good cleaning.
Replacement of the thermocouple or pilot assembly is generally not needed. Review Heater
Maintenance on page 15 of the owners manual.
While we want every one to be completely satisfied with their purchase it is impossible to cover
problems occurring form improper installation or a lack of maintenance.
