the grate only. Do not pick the unit up by 

the burners.

  Gloves are recommended when handling 

ceramic fiber logs to prevent skin irritation 

from  loose  fibers.  Logs  are  fragile  —  

handle with care.

In planning the installation for the fireplace it is necessary 

to determine where the unit is to be installed and whether 

optional accessories are desired. Gas supply piping should 

also be planned. The following steps represent the normal 

sequence of installation. Each installation is unique, how-

manual. The canopy MUST be installed for safe opera-

tion of the unit.

to the 

Electrical Section

 found in this manual. (Electrical 

connections should only be performed by an experi-

enced, licensed certified tradesman).

4.   Install optional ON/OFF kit on units with millivolt control. 

Refer to the installation instructions included with the 

kit and also refer to the 

Electrical Wiring

 section found
