WARNING ICON

G 001

 WARNINGS

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,
explosion, electrical shock, and carbon monoxide poisoning.

WARNING ICON

G 001

 DANGER

Carbon monoxide poisoning may lead to death!

SAFETY

INFORMATION

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 be working properly. Get fresh air at once! Have fireplace
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.

Natural Gas

: Natural gas is odorless. An odor-making agent is added to natural

gas. The odor helps you detect a natural gas leak. However, the odor added to
natural gas can fade. Natural 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 fireplace.
