tive harm.

IMPORTANT: Read this owner’s 

manual carefully and completely 

before  trying  to  assemble,  op

-

erate  or  service  this  fireplace. 

Improper  use  of  this  fireplace 

can  cause  serious  injury  or 

death  from  burns,  fire,  explo

sion, electrical shock and carbon 

monoxide poisoning.

 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 
be working properly. 

Get fresh air at once!

 

Have  fireplace  serviced.  Some  people  are 

more affected by carbon monoxide than oth-

ers. 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 Gas:

 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.

  WARNING:  Any  change  to 

this  heater  or  its  controls  can 

be dangerous.

 WARNING: Do not allow fans
