INSTALLATION
The dimensions shown in Figures 4 through 10 and defined in the fireplace 
manufacturer's instructions are minimum clearances to maintain when 
installing  this  heater.  Left  and  right  clearances  are  determined  when 
facing the front of the heater.
When heater is installed into a ventless firebox, minimum clearances, 
as specified by the ventless firebox manufacturer, must be met.
Follow these instructions carefully to ensure safe installation. Failure 
to follow instructions exactly can create a fire hazard.
Sidewall and ceiling clearances: The sides of the fire-
place opening must be at least 16" from any combustible 
wall. The ceiling must be at least 42" from the top of the 
fireplace opening.

To  install  the  gas  logs  into  a  fireplace  with  no  wooden 
mantel,  shelf  or  other  combustible  projection  above  the 
fireplace  opening,  measure  the  heat  resistant  material 
height, per Figure 5, then see TABLE A.
Heat resistant materials such as slate and marble must be 
at least 
1
/2" thick. Sheet metal should not be installed
