Universal Unvented Room Heater
DANGER: Carbon monoxide poisoning may lead to death.
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, persons with heart or lung disease or
anemia, those under the influence of alcohol, and those at
high altitudes.
Natural and Propane/LP Gas:
Natural and Propane/LP gases are odorless. An odor
making agent is added to these gasses. The odor helps
you detect a gas leak. Gas may be present even though
no odor exists. Make certain you read and understand all
warnings. Keep this manual for reference. It is your guide
to safe and proper operation of this heater.

PRECAUTIONS:
1. 10,000 BTU may be installed in a bedroom, but shall not
be installed in a bathroom or any place where a strong
wind would shut down the appliance.
2.
This heater needs outside ventilation air to run properly.
The Oxygen Depletion Sensor (ODS) safety shutoff
system shuts down the heater if not enough fresh
air is available. See
Fresh Air for Combustion and
Ventilation
, page 4.
3. Keep all air openings in heater clear, free of debris
or any blockage. This will ensure that enough air for
proper combustion enters the heater.
4. If heater shuts off, do not relight until you provide fresh,
outside air. If heater keeps shutting off, it requires
servicing.
5. Turn off and let cool before servicing. Only a qualified
service person should service and repair heater.
6. Do not run heater:
•
Where flammable liquids or vapors are used or stored
•
During dusty conditions.
7.
Before using furniture polish, wax, carpet cleaner or
similar products, turn heater off. If heated the vapors
from these products may create a white powder residue
within burner box or on adjacent walls or furniture.
8.
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.
9.
Operating heater above elevations of 4,500 feet could
cause pilot/ODS to shutdown heater.
10. Always run heater with control knob in a locked
position. Never set control knob between locked
positions. Poor combustion and higher levels of carbon
monoxide may result if control knob is left between
locked positions.
**Operating heater above elevations of 4,500 feet could cause pilot/ODS to shutdown heater.**
