UNVENTED NATURAL GAS FIREPLACE

LFP33NR

SAFETY
INFORMATION

 DANGER: Carbon monoxide

poisoning may lead to death!

Carbon Monoxide Poisoning: 

Early

signs of carbon monoxide poisoning re-
semble the flu, with headaches, dizziness,
or nausea. If you have these signs, the fire-
place 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 preg-
nant women, people with heart or lung dis-
ease 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 the gas. The
odor helps you detect a gas leak. However,
the odor added to the gas 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 fireplace.
