WARNING: Any change to this heater or its con-
trols can be dangerous.

patterns. Ceiling fans can create drafts that alter

SAFETY INFORMATION
IMPORTANT: Read this owner’s manual carefully
and completely before trying to assemble, operate, or
service this fireplace. Improper use of this fireplace
can cause serious injury or death from burns, fire,
explosions, electrical shock, and carbon monoxide
poisoning.
WARNINGS
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 fireplace may not have been installed
properly. Get fresh air at once! Have fireplace inspected and
serviced by a qualified service person. 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.
Propane/LP gas and natural gas are both odorless. An odor-making
agent is added to each of these gases. The odor helps you detect a gas
leak. However, the odor added to these gases can fade. 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.
