DANGER: Carbon monoxide poisoning may 

lead to death!

Carbon Monoxide Poisoning: 

Early signs of carbon mon-

oxide 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 ser

-

viced. 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 and Propane/LP gases are odorless. An odor-making 

agent is added to these gases. 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.
