Unvented Liquid Propane Fired Room Heater
DANGER: Carbon monoxide poisoning may lead to
death.
Carbon Monoxide Poisoning:
Early signs of carbon monoxide poisoning resemble
the fl u, 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
infl uence of alcohol, and those at high altitudes.
Propane/LP Gas:
Propoane/LP gas is odorless. An odor making agent is
added to propane/LP gas. The odor helps you detect
a Propane/LP gas leak. However the odor added to
propane/LP 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 units may be installed in a bedroom, but
not a bathroom, or any place where a strong wind
would shut down the appliance.
WARNING: An unvented heater having an input
of more than 10,000 Btu/hr (2 931W) shall not be
installed in a bedroom or bathroom.
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 insure 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 qualifi ed
service person should service and repair heater.
6. Do not run heater:
• Where fl ammable 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 underwater.
Immediately call a qualifi ed service technician to
inspect the room heater and to replace any part of
the control system and any gas control which has
been underwater.
9. Operating heater above elevations of 4,500 feet
could cause the 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.
